Lenovo IdeaPad Slim 3 deal is a ‘great value’ fuss-free work laptop

Published

on

If you just need a reliable Windows laptop for everyday use, this Lenovo deal is a genuinely good price – it’s an easy recommendation for remote and hybrid workers, and for my money, it ticks all the boxes for general business work.

So, right now, the Lenovo IdeaPad Slim 3i has dropped to £499 (was £599) at Argos. For an all-rounder business laptop, this one of the best budget picks around for under £500.

Inside, the machine is equipped with an efficient Intel Core i5 13420H processor and 16GB RAM, so essential office tasks, photo editing, browsing, and streaming won’t be a problem – no slowdowns or sluggishness here.

Today’s top Lenovo laptop deal

This is a budget-friendly configuration built around Intel’s Core i5-13420H, an 8-core, 12-thread chip from the 13th-gen Raptor Lake-H family, with four performance cores boosting up to 4.6GHz and four efficiency cores.

The 15.3in WUXGA (1920×1200) IPS panel uses a 16:10 aspect ratio, which gives you a bit more vertical space for documents and browsing than the more common 16:9 laptops in this price range. It’s rated at 300 nits with an anti-glare coating, with decent contrast and color accuracy (provided you calibrate it). That makes it ideal for creating images for, say, your work’s social media pages, though I wouldn’t recommend it for colour-critical tasks required by creative professionals.

16GB of RAM and a 512GB SSD is a sensible balance for this price point — enough headroom for normal multitasking across browser tabs, office apps, and streaming without feeling cramped. The laptop weighs 1.59kg and measures 17.9mm thick, with Lenovo quoting up to 14.5 hours of battery life, though real-world use — especially on the Intel variant — will likely fall short of that figure.

Connectivity is fairly standard for the budget class: two USB-A ports and one USB-C port, all capped at 5Gbps, plus HDMI 1.4 (so no native 4K60 output — you’ll need the USB-C port’s DisplayPort Alt Mode for that), a full-size SD card reader, and a 3.5mm headphone jack. Wi-Fi 6 and Bluetooth round out the wireless side.

Best Budget Earbuds for 2026: Cheap Wireless Picks

Published

on

Baseus Inspire XP1: A trickle of earbuds from value oriented brands have come out in the last year in collaboration with Bose, which has been gradually expanding its “Sound by Bose” initiative that brings its brand to more affordable headphones and earbuds. Like the Skullcandy Method 360 ANC earbuds, the Baseus Inspire XP1 feature very good sound in a set of comfortable earbuds that share some similarities with Bose QuietComfort Ultra earbuds, particularly how they fit (they have similar ear tips to the Ultras, and the buds fit my ears quite well). The Inspire XP1’s price fluctuates and sometimes dips to $100, which is the best time to buy them.

Anker Soundcore Liberty 4 NC: Released in 2023, the Anker Soundcore Liberty 4 NC earbuds carry a lower list price than 2022’s Liberty 4 buds and are arguably better in some ways. They have improved noise cancellation and better sound quality, along with support for the LDAC audio codec for devices that support it. (Many Android smartphones do, and in theory it offers slightly improved sound quality when paired with a music streaming service that offers high-res tracks.) Nicely discounted, they’re lightweight buds that should fit most ears comfortably with four sizes of ear tips to choose from. That said, the newer P31i cost less and offer similar performance.

QCY MeloBuds Pro: Like Earfun, QCY makes a variety of budget earbuds and headphones that deliver good bang for your buck. The MeloBuds Pro look a little generic, but they’re lightweight and comfortable and sound good for what they cost, offering decent clarity and well-balanced audio (you can tweak their sound profile a bit with the EQ settings in the QCY companion app). Also, they’re noise-canceling and voice-calling performance are better than average for sub-$50 earbuds. And finally, they have ear-detection sensors, multipoint Bluetooth pairing, a low-latency gaming mode and support for Sony’s high-quality LDAC audio codec (many Android devices support LDAC).

Roseselsa Ceramics X: Truth be told, I’d never heard of the Roseselsa Ceramics X earbuds before I saw a post comparing them to Final Audio’s more expensive ZE3000 SV buds that argued the two models are essentially the same. This would make the Ceramics X far better value but it didn’t quite prove to be true. While I ended up liking the Final Audio ZE3000 SV better, I was impressed by the sound quality of the Ceramics for how little they cost. Also, not only did they fit my ears well, but I thought their noise canceling was effective, and their voice-calling performance was acceptable. They also support the AAC and LDAC audio codecs for Bluetooth playback (many Android smartphones support LDAC).

Anker Soundcore AeroFit 2: Anker’s Soundcore AeroFit 2 used to be on list but their list price has risen from $100 to $130, so I had to pull them off. These open earbuds have been completely redesigned and look quite different from the original AeroFit buds, which also listed for $100. The second-gen Aerofit are not only more comfortable but look sleeker, sound significantly better and offer all-around improvements. The buds aren’t as light as the Shokz OpenFit 2 buds and don’t sound quite as good, but they cost quite a bit less and offer good all-around performance with augmented bass response. Available in multiple colors, they’re a good option for those looking for ear-hook style open earbuds with a fairly premium design and good sound quality without the high price tag of top-end models.

Soundpeats Air3 Deluxe HS: What makes these $40 Soundpeats Air3 Deluxe HS buds special is that they sound surprisingly good for open earbuds — they’re close to what you get from Apple’s AirPods 3 for sound (they’re a little more behind the AirPods 4, which offer improved sound from the AirPods 3). On top of that, they support Sony’s LDAC audio codec for devices that offer it. Not too many cheap open earbuds have good sound but these Soundpeats have good bass response and clarity. They’re also good for making calls and have a low-latency gaming mode. Battery life is rated at 5 hours at moderate volume levels, and these are IPX4 splash-proof.

Amazon Echo Buds (2023): Amazon’s 2023 Echo Buds impressed me in a few ways that I wasn’t expecting. For starters, they sound good for inexpensive open earbuds, delivering decent clarity and ample bass. But they also have a robust feature set, including multipoint Bluetooth pairing, hands-free Alexa and ear-detection sensors that pause your audio when you take one or both buds out of your ears. Their sound falls short of that of Apple’s AirPods 4, which deliver better bass performance and overall fuller, cleaner sound (they’re better at handling more complicated music tracks with a lot of instruments playing at the same time). But the AirPods 4, even the entry-level model ($129), cost significantly more.

Jabra Elite 4: The lightweight Elite 4 fit my ears comfortably and offered good, well-balanced sound with punchy bass and decent clarity. They support Qualcomm’s aptX audio codec (for Android and other devices that support aptX) but only the SBC codec for iPhones (no AAC support). The Elite 4 is missing more premium features like ear detection sensors and has a four-microphone array for noise canceling and voice calls (voice-calling performance is good but not exceptionally good). What’s a little confusing is that Jabra also sells the Elite 4 Active, a slightly more ruggedized version of the same buds that carries a list price of $120 but sometimes sells for less than the standard Elite 4. So get the Elite 4 Active if it costs less.

JBL Live Pro 2: Over the years, JBL has put out some decent true-wireless earbuds, but nothing that really got me too excited. That’s finally changed with the arrival of the Samsung-owned brand’s new Live Pro 2 and Live Free 2 buds. Both sets of buds — the Live Pro 2 have stems while the Live Free 2 have a pill-shaped design — offer a comfortable fit along with strong noise canceling, very good sound quality and voice-calling performance, plus a robust set of features, including multipoint Bluetooth pairing, an IPX5 splash-proof rating and wireless charging.

JBL Live Free 2: Like the Live Pro 2, JBL’s new Live Free 2 buds are surprisingly good. With 11mm drivers, six microphones, oval tubes and oval silicon tips, they combine a comfortable fit along with strong noise canceling, very good sound quality and voice-calling performance. Features include multipoint Bluetooth pairing and wireless charging, and they’re rated for up to seven hours with IPX5 water-resistance (splash-proof).

Beats Studio Buds: The Beats Studio Buds look a lot like the rumored stemless AirPods some people have been waiting for. Geared toward both iOS and Android users, they are missing a few key features on the Apple side of things (there’s no H1 or W1 chip), but they’re small, lightweight buds that are comfortable to wear and offer really good sound. While their noise canceling isn’t as good as the AirPods Pro’s, they do have a transparency mode and they’re decent for making calls. Read our Beats Studio Buds review.

Sennheiser CX: If you can’t afford Sennheiser’s flagship Momentum True Wireless 4 earbuds, the CX are a good alternative. They feature very good sound, plus decent noise canceling and voice-calling performance. The only issue is they stick out of your ears a bit and may not fit some smaller ears. This model, which often sells for less than $100 on Amazon, doesn’t feature active noise canceling but the step-up CX Plus does (the CX Plus is also a good value, particularly when it goes on sale). Learn more about the budget earbuds in my full Sennheiser CX true wireless earbuds review.

Final DX10000 CL Headphones Pack True Diamond Drivers and an $8,500 Reality Check

Published

on

Final has unveiled the DX10000 CL, a new closed-back flagship headphone built around a 40mm True Diamond dynamic driver, with pre-orders opening July 9, 2026. The standard edition is priced at $8,499, while the first 150 units will be sold as a Collector’s Edition for $8,999. Because apparently the headphone market looked at five-figure loudspeaker cables and said, “Hold my paulownia wood box.”

Before anyone starts polishing the Crown Jewels, Final is not exactly operating in uncharted waters here. Diamond material has already appeared in personal audio, including Periodic Audio’s Carbon IEM, TXN Sound’s Diamond IEM, and a much wider field of diamond-like carbon driver coatings used by brands such as Campfire Audio and Austrian Audio.

The difference is that Final is not merely saying “diamond-like” or using diamond as jewelry-counter shorthand. The DX10000 CL uses a CVD-grown True Diamond diaphragm in a full-size closed-back flagship headphone, and Final has built the entire acoustic system around it.

The timing is also worth noting. The high-end headphone category has been moving well beyond the old $1,000 psychological barrier for years. Meze Audio recently announced the ARTA at $6,000 with a 225-ohm high-impedance planar magnetic driver; Audeze’s LCD-5s sells for $4,500 and adds SLAM acoustic management to its planar platform; the Audeze CRBN2 electrostatic headphone is $5,995; and Meze’s Elite Tungsten remains a $4,000 planar magnetic headphone.

The DX10000 CL is more expensive than all of those, so Final had better be bringing more to the table than a shiny diaphragm and a huge asking price.

What Makes the Final DX10000 CL Different?

The core of the DX10000 CL is its 40mm True Diamond diaphragm dynamic driver. Final says the center dome is produced using Chemical Vapor Deposition, where diamond is grown as a crystalline layer before the substrate is removed, leaving a self-supporting diamond dome. That matters because this is not the same thing as a common DLC coating placed over another diaphragm material.

final-dx10000-cl-collectors-edition-headphones-5

Final’s argument is straightforward: diamond offers very high rigidity, high sound velocity, and strong internal damping, which should help the driver maintain piston-like motion, reduce deformation, and suppress residual vibration after the signal stops.

The company has also redesigned the supporting driver assembly, including a polyurethane surround, lightweight polyimide bobbin-integrated voice coil, free-floating lead wire structure, N55 neodymium magnet, aluminum shorting ring, and internal damping system. Exotic diaphragm materials do not automatically guarantee great sound. Implementation still does the heavy lifting, as usual. And that’s before you even start thinking about the source, DAC, and headphone amplifier to make this very expensive headphone worth the expenditure.

Closed-Back Is the Hard Part

The DX10000 CL is not another open-back flagship chasing a huge soundstage and then calling isolation someone else’s problem. Final is taking on closed-back headphone design, which is harder to get right at this level because rear sound waves reflect inside the enclosure and can create resonance, coloration, and that familiar cupped-in effect.

To address that, Final uses a high-rigidity, airtight housing machined from an aluminum-magnesium alloy with 5-axis CNC machining. Inside the housing, unnecessary material is removed to reduce weight, and the resulting cavities are filled with dedicated acoustic damping material to control internal reflections.

The earpads are also part of the tuning strategy. Instead of relying on a fully sealed pad that increases low-frequency pressure and then correcting the balance with elevated treble, Final uses Ultrasuede with controlled air permeability and a selected foam material.

The goal is to manage the ear chamber more naturally while maintaining an effective seal. That is a smarter claim than simply promising “more bass,” which is one of the most abused marketing terms around in the Head-Fi world.

Better-defined bass with real clarity, detail, and texture should be expected from an $8,500 headphone, but we’ll see whether Final’s driver, enclosure, and damping choices actually deliver.

Built to Be Serviced, Not Worshipped From Across the Room

One of the more useful details is the DX10000 CL’s 12-point through-bolt construction. Final says the housing assembly is clamped together with 12 screws rather than adhesive, allowing the headphone to be disassembled and serviced. Wear components are replaceable, which matters when the standard version costs $8,499 and the Collector’s Edition costs $8,999. At that price, “throw it out when the pads go” would be immediate grounds for a red card and that one is not being overturned because someone makes a phone call.

The Collector’s Edition adds gold-colored accents, a traditional Japanese paulownia wood box, a Shingen Pouch made from Tango Chirimen silk, and a CNC-machined aluminum headphone stand. The standard edition uses silver-colored accents and ships with the protective carrying case used across Final’s D Series headphones.

Cables and Connectivity

Final includes two silver-coated OFC cables co-developed with Junkosha: a 4.4mm balanced cable at 1.5 meters using ePTFE insulation, and a 4-pin XLR cable at 3 meters using larger conductors and PFA insulation. Final also includes two adapters: 4-pin XLR female to 6.3mm male, and 4.4mm female to 6.3mm male. That gives the DX10000 CL broad compatibility with desktop headphone amplifiers and high-end audio systems.

final-dx10000-cl-collectors-edition-headphones-box

Final DX10000 CL Specifications:

  • Headphone Type: Closed-back over-ear headphone
  • Driver: 40mm True Diamond diaphragm dynamic driver
  • Diaphragm Process: CVD-grown diamond center dome
  • Housing: Aluminum-magnesium alloy
  • Magnet: N55 neodymium
  • Voice Coil: Lightweight polyimide bobbin-integrated structure
  • Shorting Ring: Aluminum
  • Earpads: Ultrasuede with selected foam material
  • Construction: 12-point through-bolt serviceable housing assembly
  • Impedance: 20 ohms at 1 kHz
  • Sensitivity: 92 dB/mW at 1 kHz
  • Weight: 543 grams
  • Included Cable: 4.4mm balanced, 1.5m, silver-coated OFC with ePTFE insulation
  • Included Cable: 4-pin XLR, 3m, silver-coated OFC with PFA insulation
  • Included Adapters: 4-pin XLR female to 6.3mm male; 4.4mm female to 6.3mm male
final-dx10000-cl-collectors-edition-headphones-6

The Bottom Line

The DX10000 CL stands out less for using diamond as a driver material and more for how Final applies it: a CVD-grown True Diamond diaphragm inside a closed-back flagship with a rigid aluminum-magnesium housing, controlled internal damping, and serviceable construction.

At $8,499, expectations are high. This is for serious headphone listeners who want a closed-back reference design, already have a capable desktop system, and are willing to pay for Final’s specific approach to driver material, enclosure control, and long-term ownership.

Bellevue, Wash.-based Pulse Space says it has received a $40 million award from the U.S. Space Force to develop technologies for laser-based power beaming and orbital tracking systems.

The startup, founded in 2022, is working on a system that would collect energy using solar arrays and send that energy via a laser beam to remote nodes in space. The technologies developed for the system could also be used to track objects in orbit and transmit data.

“This historic $40 million award is a defining moment for Pulse Space, and I am exceptionally proud of our team for making it happen,” Karl Stedman, Pulse Space’s founder and CEO, said today in a news release. “We are honored to partner with the United States Space Force to mature our laser-based technologies and are proud to share this massive step forward with our investors and shareholders. Pulse’s technical development platform is helping pave the way toward that future.”

Pulse Space was previously awarded a $1.9 million Air Force contract in support of its work on laser-based military communications systems. The company said its proposed satellite constellation would support “secure, high-bandwidth optical communication and energy delivery,” with the ability to transmit 29.7 kilowatts of power to a 3-meter (10-foot) target from 1,000 kilometers (621 miles).

The company is also on the Missile Defense Agency’s list of potential vendors for SHIELD contracts, with a ceiling of $151 billion. SHIELD — which stands for Scalable Homeland Innovative Enterprise Layered Defense — is a program that encompasses a broad range of work areas for the Pentagon’s Golden Dome missile defense initiative.

The Best Tech-Packed E-Bike Yet

Published

on





I had a chance to test out the Segway Myon e-bike at CES 2026, back in January and I’ve been thinking about it ever since. In Las Vegas, this bike blew me away. Now that I have one, I’ve found a few warts, but I’m still genuinely impressed.

I’m a 49-year-old, 270-pound man who is riding a bike for the first time in two weeks. Why it’s the first time in two weeks is a subject we’ll discuss in a little bit, but suffice it to say, it’s been a while since I’ve had the opportunity to get out and cruise. I biked from my home in Streamwood, IL over to the city of Elgin, along the river for a spell to the Illinois Prairie Path, on to the Great Western Trail, back over to Woodfield mall, and finally back to my home.

I just crossed my 50th mile on this trip. I’ve been biking for just over four hours in 87-degree heat. Overall, I’m tired, but I feel pretty good, and I have the bike under me to thank for it.

Advertisement

Put simply, this bike packs the most technology I’ve seen in a bike that costs less than $2,000. There’s a lot to love here, and it doesn’t cost much to love it — comparatively. $2,000 is a lot of money, but what you get compared to what you get in other e-bikes is outstanding. It’s no exaggeration to say that this sets the new standard for e-bikes in America.

Smooth riding

One of my favorite parts about this bike has to be the motor. It is incredibly powerful and very smooth. The bike uses a torque sensor to determine when assistance in needed. A torque sensor can tell how much effort you’re putting into pedaling and nudge you a little faster and a little harder. It doesn’t take much for it to kick in, but when it does it feels natural — as if you’re just pedaling a little bit harder. By comparison, a cadence sensor detects when the pedals move and engages the motor basically whether you need it or not. Overall, I vastly prefer torque sensors.

As far as the assistance is concerned, you can set your own level. For the most part, I left the assist level between one-quarter and one-half power. I basically never needed more than that; it was plenty. On the 50-mile journey that culminated my review period, I kicked it up to half power toward the end, both because I didn’t need to conserve the battery as much, it was largely uphill, and because I was getting pretty gassed.

It’s not cheating

Some people will look at someone riding an e-bike and consider them to be cheaters. I totally see where that opinion is coming from, but after this latest ride, I can very much assure you that is not the case. Basically, it’s like being in a four-hour spin class. That’s no joke. The Myon has a throttle as well, so it is possible to just cruise on this bike if you want, but that takes a big hit on the battery.

For one trip, I biked about 12 miles from my home to a newly-published geocache — I was the first to find it, thank you very much. On the way back, I decided to just let the bike do the work. The trip down used about 20% of the battery. The ride back depleted it by nearly 50%. You’re better off biking, using the motor to assist your pedaling, rather than just wholesale relying on the throttle. The motor is so powerful, you don’t need to turn up the assistance much at all, but your legs will be doing some work, for sure.

The tech packed in

The Segway Myon has a ton of useful tech built into it. Of course, there’s a bright, full color display in the middle of the handlebars. On each end is a turn signal that flashes the handlebars front and back so everyone knows where you’re going. The bike also has a lot of security features like Airlock, which allows you to unlock the bike just by having your phone nearby. When the bike is locked and it’s moved, the real wheel locks and won’t spin and a loud klaxon sounds indicating the bike is being moved without its owner nearby.

I found this feature to be a tad annoying — my phone didn’t unlock the phone or prevent the alarm from sounding nearly in time. Most of the time, I had to pull my phone out of my pocket and manually unlock the bike in the app just to shut it up. I like the idea of the locking rear wheel and alarm, but overall, Bluetooth doesn’t seem quick or reliable enough to make that connection and disable those features before they annoy you.

Moreover, the security features are hard on the battery — draining it by about 9% overnight. That’s not great. If you don’t ride your bike and don’t leave it plugged in, you may go out after three days and find a quarter of the battery drained. What would make this feature better would be a geofence that allows you to disable all those features when you are home, so the bike knows that it’s safe, so it can relax and save some battery.

Navigation with Here maps is (currently) terrible

The bike also comes with built in navigation, which is a really cool concept, but it’s fundamentally flawed in a number of ways. Most notably, navigation relies on app connectivity which, as I’ve already discussed, is far from perfectly. That’s already not great. The app has a navigation feature that remains hidden until you expose it. I had to edit the quick options in the app to locate navigation panel in order to actually use it, but that’s still not the worst part about the navigation.

The bike uses Here maps to navigate. I have a lot of respect for Here — it was the default navigation app for Windows Phone; I’m a fan. But Here maps is terrible for biking directions, and it’s worth reiterating that this navigation…is for a bike.

On any given route, I entered the destination on Google Maps and in the Segway navigation app, and without fail, Google had better directions. In one instance, Here wanted me to ride my bike on the shoulder of a thoroughfare with a posted speed limit of 45 mph while Google (rightly) directed me to the bike path that literally ran parallel to the road 50 feet to the north. It got to the point where I simply stopped using the bike’s (Here) navigation because it was, for all intents and purposes, useless.

Advertisement

Quality, but delicate construction

The build quality of the bike is very solid, and very heavy. The bike has a step-through frame, with an optional body bar. I left it off — I’m old and I prefer step-through frames. Each handlebar has a controller with buttons and switches that control the technology on board. A joystick on the left side switches you between screens, and rocker switch on the right controls the gears for the bike — electronic switching is quite handy by the way. In a couple of weeks, Segway will roll out an automatic gear switching feature. When I receive that update, I will test it and if it significantly improves the overall experience, I’ll be sure to update this review.

The problem I ran into (and the reason why I didn’t ride a bike for two weeks) was because at some point when either loading or unloading the bike from my car, the pedal assist rocker switch popped off and I lost it. Segway sent over a new control unit which required disassembly of the handlebar, and when I tried to reconnect the wires to the control board, I inadvertently bent delicate pins inside one of the connectors. I had to head to a bike shop where they were able to straighten the pins and get the connector working again.

When I looked more closely at the rocker switch that popped off I could easily see how it happened. The button had a small slot below it that could easily catch on a sharp edge and pop the button right off. The pins inside the connector are also a bit too easily bent for my taste. I hope Segway takes these notes to heart when designing its next bike.

Intuitive and easy

Overall, the bike is easy to ride and control. I sometimes found myself turning on the turn signal when I meant to adjust the pedal assistance because the rocker switches are identical left and right. Beyond that though, I love the idea of navigation built into the display, and media controls which you can adjust via that control screen.

The bike can also switch between being a class 2 and a class 3 e-bike. The difference is a class 3 e-bike can go up to 28 miles per hour, but that disables the throttle entirely. I left the bike in Class 2 mode for most of my review period because I like having the throttle if I need it, and 28 miles per hour is too fast for trail riding, which is where I spent most of my time. All that being said, I wouldn’t hate it if Segway made the switch a little easier to access.

Segway Myon pricing, availability, and verdict

I love this bike, paint points and all. I could see any one of the issues I ran into turning you off — that’s fair. But this is by far the best value you can find in an e-bike of this quality. The bike retails for $1,999.99 — you can buy the Segway Myon from the Segway store online, now. In the world of e-bikes, the average is around $1,200 to $1,500, so this bike is more expensive than other options. But the sheer amount of (useful, functional) tech built into this bike makes it worth it.

Other e-bikes have similar features — a color screen, a smooth torque sensor, turn signals — but no other bikes have all of these features for this low a price. Which is why, when I asked the bike shop how often they’ve sold one (since they started selling them earlier this year, 2026), they told me they sell about one per week.

But there is room for improvement. Here maps is basically a non-starter for navigation. It actually makes me wonder if Segway even tested the navigation before shipping it. I get Here maps is probably less expensive to license than bigger-name alternatives, but it’d almost be better to have nothing. 

I’d also like to see geofencing implemented to save the battery while you’re storing the bike at home.

But beyond that, this is absolutely a bike you should consider if you’re in the market. The overall experience is absolutely premium, and there’s just enough room for improvement that makes me really excited to see what the company will offer next year.

Fixing A Dodgy Cheap Audio DAC

Published

on

One of the attractions of buying at the bottom end of the electronics market by mail order from China is that you never quite know what will come your way. Sometimes it’s a diamond in the rough, while with others it’s a mess. Occasionally along comes something which should work but doesn’t, and that’s the moment when you wonder if you could fix it. [Nyanpasu64] had just such a device, an HDMI to VGA converter with audio that didn’t work. What could be wrong?

The HDMI to VGA chip has an onboard audio digital-to-analog converter (DAC), and it’s a delta-sigma design. This type of DAC is frequently used in audio applications because it works by shifting its switching frequency many times higher than the input sample rate, thus reducing considerably the distortion. This one wasn’t performing as advertised though, and the problem turned out to be that switching frequency being all over the output. Clearly the filter wasn’t working, which led to the design of a new filter. The write-up is therefore an extensive dive into filter design, and in part also a discovery of the effect of impedance on them.

For a super-cheap module to cause so much work, one might ask why not simply spend a few more dollars and get a better one. But had they done that we wouldn’t have seen this write-up, so we’re sticking with team cheap.

A Brief History Of The Crazy Old 7-Segment Display

Published

on

How old is the seven-segment display? Surely it is a product of the 1970s. After all, calculators started showing up, and the height of junior high humor was plugging 7734 into your calculator and showing it to someone upside down. Of course, for it to go mainstream, maybe they really originated in the 1960s, but no earlier than that, right? Actually, no. Sure, the LED seven-segment display had to wait for LEDs. But the actual idea is much older than that.

The concept of building numbers from a small set of reusable segments predates LED displays by decades. In fact, the basic idea appears in patents from the early 1900s and may have roots in even older mechanical signs and printing techniques.

The history isn’t entirely straightforward. Unlike vacuum tubes or transistors, segmented displays evolved gradually through a series of practical ideas rather than one defining invention.

Blacking out the Eight

While looking into the history of segmented displays, I was reminded of something I’d seen years ago in retail stores: reusable price tags printed with rows of eights.

Advertisement

Rather than printing every possible price, the clerk simply used a marker to black out portions of each figure, transforming an 8 into whatever digit was needed. Cover a few strokes, and the eight becomes a three. Remove a different set, and it becomes a zero or a five. It was, in essence, a manual segmented display.

Finding the exact origin of these price tags is akin to finding out where Romans bought sponges. They were inexpensive commercial supplies, not the sort of products that historians carefully documented. My recollection is from the middle of the twentieth century, but the underlying concept is almost certainly older.

Everything New is Old Again

George Mason’s 1898 21-segment display used 21 lamps and a complicated switch to display any digit or letter in a very stylish font. You can see a modern recreation of these ancient displays in the video below. While this is the basic idea, certainly, it is more ambitious than a simple 7-segment display.

I couldn’t determine that Mason’s displays were ever used for anything.

You could argue that an early 1903 invention by Carl Kinsley to draw characters telegraphically using six pens was an even better precursor, but using magnets to draw with pens on tapes hardly seems to qualify as a display, although figure 12 in the patent clearly shows the formation of numbers and even letters with this arrangement.

Digits of Patent

The direct parent of modern segmented digit displays appeared in the early 1900s (filed 1908; granted in 1910). Technically, this was an 8-segment display because it had a bar dedicated to forming a proper four, with the top-left part slanted. But removing that one segment is just an optimization. It may or may not have been the first, but by 1910, seven-segment displays were in use and not just curiosities on a workbench or dreams in a patent application.

Even for lit-up displays, the first implementations weren’t LEDs. Early displays used incandescent lamps or neon-filled tubes. By the 1930s and 1940s, segmented neon or incandescent indicators were appearing in industrial equipment and counters, instead of the common columns of ten neon bulbs, pointers, or rotating wheels.

Then, too, there were different approaches. Nixie tubes used individual character forms that lit up. Decatrons could count with ten different glowing points, each representing a digit.

Enter the LED

The real explosion came in the late 1960s when practical LED displays arrived. Suddenly, segmented displays could be compact, rugged, inexpensive, and operate at low voltages. Calculators, clocks, frequency counters, digital multimeters, and every imaginable piece of consumer electronics adopted them almost overnight.

Of course, it wasn’t just LEDs. Numitrons used seven tiny incandescent filaments. Vacuum fluorescent displays used segments with phosphor that glowed when excited. LCDs adopted the same pattern, blocking or passing light to produce the segments. But the key idea was something that lights up, arranged in seven segments.

Radio Shack’s 1976 catalog featured magnified LED displays.

Early LED displays often had all the diodes on a single die to reduce cost. That made them very tiny. It wasn’t unusual to see displays with magnifying bubbles to make it easier to read.

The important point isn’t whether they used exactly seven segments. Many didn’t. Some divided the numerals differently or used additional pieces to produce more attractive typography. The insight was the same: begin with the most complex digit and selectively remove strokes to create all the others.

Why Seven?

One of the reasons seven segments became the standard is that they strike a perfect balance (although not everyone agrees, as you can see in the video below). With fewer than seven elements, several decimal digits become difficult to distinguish. Adding more segments certainly improves appearance, but every additional segment increases wiring, decoding logic, manufacturing cost, and the number of possible failure points. Seven is the right number for — um — numbers. But what about letters?

You can make some compromises to show some letters. For example, old computers would display hex digits using seven segments, but the A would be uppercase and the B would be lowercase. You also had to light the top segment for the 6 to make it look different from a B. But you only need A-F for hex. If you need, say, the letter S, there’s no real way to make it not look like a 5 with 7 segments. But sometimes, the letters you can make are good enough.

There were also 8- and 9-segment displays that could do better with letters and special characters. You can increase the segments further to get more glyphs.

The Union Jack

Different segment counts for displays (public domain by [errorage])

The solution for full letter displays was to add more segments. Despite Mason, you didn’t really need 21. By the 1970s, fourteen-segment and sixteen-segment displays had become common in instruments, telephones, calculators, and video cassette recorders. Their pattern of diagonals and crossbars earned them the nickname “Union Jack” display because the arrangement resembles the British flag. These are also sometimes called starburst displays. You occasionally see 16-segment displays, too.

Even Today

Today, you have a plethora of options for adding alphanumeric screens to just about anything. Yet, you still see 7-segment displays hanging around.

The seven-segment display isn’t successful because it’s beautiful. It isn’t even especially flexible. It’s successful because it’s close to the minimum solution that works. It delivers readable numbers with very little hardware, whether the technology behind it is incandescent bulbs, neon, vacuum fluorescence, LEDs, LCDs, or even ink on a printed price tag.

Perhaps that’s why it has survived every technological transition for more than a hundred years. Good engineering ideas often outlive the technologies that first bring them to life.

And once you start looking for segmented displays, you’ll notice they’ve been hiding in plain sight for much longer than the digital age.

The enterprise AI challenge nobody solves with code generation alone

Published

on

Presented by SAP


Generating code with AI is fast, but getting that code to run reliably inside a large enterprise, integrated with live systems, governed for compliance, and maintainable over years requires foundational work that most organizations underestimate.

While 81% of all organizations have a detailed strategy, only 12–16% reach AI‑driven execution, says SAP’s Michael Ameling, CPO of SAP Business Technology Platform, and the reasons rarely come down to the quality of the generated code.

“Across industries, enterprises that have invested heavily in AI tooling are hitting a wall when generated code meets the reality of their existing environments, because generating code and operationalizing it are not the same problem,” Ameling says.

Advertisement

There are specific requirements for deploying AI-generated logic at enterprise scale: what data and integration readiness actually look like, how governance works when AI agents move from producing recommendations to executing workflows, and how development teams are changing their role as AI takes over more of the coding work.

Why AI code generation fails in enterprise production environments

The productivity gains from AI code generation are real and well-documented, but the ease of prototyping has given many organizations a misleading sense of how far along they actually are.

“Generating code is one thing,” Ameling says. “Enterprise customers, including multinationals and large organizations, need to ensure there are no compromises in compliance or security. Code that runs reliably for ten or twenty years, as it does at many of SAP’s largest customers, also has to be maintained, patched, and understood by whoever inherits it. Life cycle management, in other words, does not generate itself.”

The issue is rarely the generation quality. Teams build something compelling, then discover they lack access to the data it depends on, or the integrations it assumes, or the permissions required to run it in a real environment. The problem is essentially that AI amplifies an organization’s existing data and process maturity, but it can’t substitute for it.

Advertisement

This dynamic intensifies as AI moves from producing code to executing actions. Latency, cost, and system load all increase when logic runs continuously against live data rather than rendering a one-time output. The performance requirements of an autonomous agent operating across a multinational’s transaction systems are categorically different from those of a developer copilot.

How to connect AI-generated logic to fragmented enterprise systems

The architecture challenge that most enterprise AI projects underestimate is integration. Real enterprise environments are not clean slates: they combine cloud systems, legacy on-premise infrastructure, fragmented data stores, and dozens of business applications that were never designed to talk to each other. Getting AI-generated logic to operate reliably across all of them requires a layer that unifies data access, process context, and governance, and it has to be in place before any agent starts executing. And organizations that see AI as a reason to defer infrastructure modernization are making a mistake.

“The question is not whether to modernize or not. Of course you need to modernize,” Ameling says. “But the value you get on top of this is much higher with AI. Federated data access and harmonized process layers are not alternatives to upgrading a fragmented landscape, they’re what make the upgrade worthwhile.”

At the platform level, this translates into a set of practical requirements: structured data integration, end-to-end process visibility, and the ability to discover and connect to APIs across both modern and legacy systems. SAP’s approach with the Business AI Platform draws on tools including its Joule Studio, Integration Suite, Business Data Cloud, and SAP AI Agent Hub enterprise architecture layer to provide that context. The goal is to give AI-generated logic accurate, current knowledge of what a business is doing and how, rather than just access to raw data.

AI agents handle large challenges by dividing them into smaller, autonomous tasks, with each agent responsible for a specific domain, and all coordinated toward a shared outcome. A financial close, for example, involves dozens of discrete sub-processes. Agents handling each task in parallel, within defined constraints, can compress cycle times dramatically, but only if the underlying systems they interact with are coherent and accessible.

The governance and oversight that AI agents require in production

When AI moves from assistant to operational actor, the governance questions loom large, because agents that trigger workflows, update records, and interact with live business systems need the same accountability framework that applies to human employees, i.e., identities, defined privileges, and auditable behavior.

There are two distinct models:

Principal propagation, where an agent acts on a user’s behalf, inheriting that user’s permissions and scope.

Advertisement

System-triggered agents, where the agent operates under its own identity and role-defined privileges, functioning more like an automated HR role than a personal assistant.

Both models require the same underlying infrastructure: an agent hub where operators can see which agents exist, what APIs they can access, and what they are authorized to do. Observability also needs to be operationalized correctly for AI, combined with both technical and business evals.

“In production, openness is very important,” Ameling says. “We use OpenTelemetry as a framework, so we can integrate with other solutions, for end-to-end observability of the tool, third-party agents and the like.”

On top of that, standard technical evals, which test whether an agent produces consistent outputs, are necessary but not enough. Business evals assess whether an agent is actually moving the performance indicators it was deployed to improve, but it has to work end-to-end.

Advertisement

Where the testing happens is equally important. The traditional software development cycle across dev, test, and production environments breaks down when a model produces different outputs depending on whether it is running against test data or live data. Getting to trustworthy AI in production means accepting that validation looks fundamentally different from what engineering teams have practiced for decades, with live environment testing, even A/B/C testing to ensure outcomes are reliable.

How AI-driven code generation is changing software engineering roles

The role of the developer is not disappearing in this environment, but its center of gravity is shifting. The productivity multiplier is significant when developers can run multiple coding agents in parallel across open terminals, each working on a separate problem and each taking several minutes to complete. But it introduces a new kind of cognitive demand, because humans have to stay in the loop. That means tracking context across concurrent workstreams, evaluating outputs that range across large codebases, and making architectural judgments that no agent can be trusted to make alone.

“The more specific and complete the prompt, the less intervention is required, and developers are learning that bringing more context upfront pays dividends in reduced back-and-forth,” Ameling says. “But the output still needs to be understood, not just accepted.”

The competitive edge will remain intellectual property, not tooling. The companies that pull ahead will be those that most effectively encode their domain knowledge into the systems they build.

Advertisement

“A manufacturer’s process expertise, a financial institution’s risk logic, a logistics firm’s routing intelligence, these are the assets that AI can accelerate, but only if the organizations that hold them do the work to make them accessible and usable,” Ameling says. “Protect that, and apply AI to accelerate your differentiation.”

I Built the Chemistry Platform I Needed in My Own Classroom

Published

on

As a current high school student, the first thing I noticed about chemistry was that it was not only hard because of math or vocabulary. It was hard because so much of it was invisible.

In class, I could write a chemical formula. I could memorize that a molecule had a certain shape or that a reaction moved in a certain direction. But much of chemistry did not feel like something I could touch, move, test, or explore. The most important parts happened in a way I would never see.

A Two-Dimensional Perspective

Chemistry is a subject built on relationships. Atoms connect, electrons move, bonds form, molecules bend, acids and bases shift equilibrium, gases respond to pressure and temperature, and reactions balance because matter must be conserved. When those ideas stay flat on a page, students memorize answers without understanding the system behind them.

As a rising 12th-grade student at Suitland High School in Prince George’s County, Maryland, I set out to build a solution because I wanted a serious chemistry workspace students like me could use. I wanted something visual and interactive that could run on school devices without complicated setup — without the need for students to create accounts, download resources, or collect student data. I also wanted something that could open in a browser and allow students to begin learning right away.

Atomency started from a simple question: What would chemistry look like if students could build, manipulate and test ideas instead of only reading about them?

I began by building a workspace where students could create molecules and see structure-based information. From there, I added VSEPR-style analysis so students could connect formulas to molecular geometry instead of treating shapes as something to memorize from a chart. Then I kept expanding it: I incorporated reaction simulations, nuclear decay tools, kinetics tool, acid–base and pH tools, gas-law models and assignment workflows to help teachers bring the platform into the classroom.

I built all of this independently while still being a high school student. That meant I was not just designing a product in theory; I was building from inside the problem. I knew what it felt like to sit in a classroom and need a better way to see what was happening. I knew what it felt like when a concept almost made sense, but the missing piece was the ability to interact with it.

A Three-Dimensional Solution

Students usually receive educational tools instead of imagining or creating them. But students notice things adults can miss. We notice when a website is too slow on a school Chromebook. We notice when a platform requires an account before we can try it. We notice when a tool looks impressive in a presentation but does not align with the way a classroom actually works.

Access shaped how I built Atomency. A chemistry platform should not require expensive software or perfect devices. It should not require students to provide personal information. It should not assume all students have tutors, can pay to access resources, and have personal laptops powerful enough to run advanced programs. If a tool is meant to help students, it should reflect students’ reality.

For me, that reality was a public school classroom where students needed more ways to understand chemistry. Chemistry can become a gatekeeping subject. If students fall behind early, later topics become harder because everything builds on earlier ideas. Atomic structure connects to bonding. Bonding connects to molecular geometry. Geometry connects to polarity. Reactions connect to stoichiometry and equilibrium. Once one link in that chain breaks, the whole subject can start to feel impossible.

I wanted Atomency to help repair those links by making the relationships clearer. Instead of only telling students that a molecule has a certain shape, the platform can help them see how structure connects to geometry. Instead of only practicing reaction-balancing in steps, students can work with reactions as systems. Instead of treating acids, bases, gases, kinetics and nuclear decay as separate units, students can see chemistry as a connected field where patterns repeat in different forms.

Early usage showed me that students and teachers were looking for a platform like this. Atomency’s aggregate GoatCounter analytics indicated 25,162 visits from Feb. 24 to May 24, 2026, with strong engagement in the builder and simulations, the molecular workspace where students can create molecules and see structure-based information. This mattered to me not because it made the platform look popular but because it showed that people were using the parts of the platform that matched the original reason I built it: to give students a place to experiment with chemistry visually.

Atomency has been featured by Eric Curts in Control Alt Achieve and mentioned by Middle School Matters. My AP Chemistry teacher, Dr. Glenn Soltes, described the platform as having meaningful instructional potential. These moments helped me understand that the platform was not just something I made for myself. Other educators could see value in it too.

Still, the biggest lesson I learned was that students should be taken seriously as designers of learning environments. We are close to the problems because we experience them every day. When students say a tool is confusing, inaccessible, slow or disconnected from the way they learn, that feedback is not a complaint. It is design information.

Advertisement

Educational technology should not only be built for students but also with students and by students. That does not mean every student must become a software developer. It means schools and education companies should recognize that students have insight, creativity and lived experiences that can improve tools inside real classrooms.

I built Atomency because I needed a better way to learn chemistry. But as the platform grew, it became about something larger than my own classroom. It became a way to ask what happens when a student is trusted not only as a learner but also as a builder.

Chemistry became easier for me to understand when I could make it visible. Maybe school technology can become better when student experience becomes more visible too.
