Recycling Laptops And IMacs Makes PC Building Fun And Affordable Again

July 19, 2026 by 55 Comments

Building a PC used to be a fun adventure — what’s the latest, what’s the greatest, what can I afford? Well, that last question seems to have taken over and sucked all the fun out for a lot of people. [Matt] from [DIY Perks] on YouTube has hit upon a solution that’s brought back the fun, at least for him: recycling! The video is embedded below, and he runs a forum whose thread has more details.

Long story short, though, he’s flagging recycled laptop components as both good value for money and a fun rabbit hole to go down researching parts. The best part, of course, is that you can get a mobo with 32GB of RAM soldered on, and embedded RTX graphics, and a decent processor for about what you’d pay for that RAM on sticks these days. The big hack is getting the dang thing started: he needed to make a single-pin ribbon cable after identifying which pin on the keyboard membrane hit the power button. If you can score a laptop that does not power on from the keyboard, you’ll have an easier time in that regard.

Remembering The Zilog Z80 As It Turns Fifty Years Old

July 19, 2026 by 34 Comments

Perhaps the saddest thing about the Zilog Z80 is that this humble 8-bit microprocessor wasn’t allowed to live until its 50th birthday. This, fortunately, doesn’t prevent people like [David Oberhollenzer] from reminiscing on this influential processor and what it means to them personally.

First released in July of 1976, this humble 8-bit miracle would go on to power not just a range of home computers, but also be found in everything from industrial controllers to arcade systems. Despite this success, the new owner of Zilog — Littelfuse — decided to put an end to this winning streak in 2024 for the stand-alone processor and its peripherals.

QT6 Brings BASIC To The Web Browser, Or Your Computer

July 19, 2026 by 10 Comments

In the old days, you either swore by BASIC or you swore at it — but just about everybody got their start on the educational language. Nowadays, the kids are learning Python, but there’s a case to be made for BASIC — either for education, or just for nostalgic fun. BASIC-256 fills that niche, and now that it’s being ported to the oh-so-portable QT6 by [UglyMike], there’s even a webAssembly version that will let you run BASIC in your browser.

This version of BASIC is based on KidBASIC, which was aimed at the educational market. It’s got some handy-dandy graphics routines, 64-bit variables, and other quality-of-life features you can find in the docs. The new port is multi-platform, though the MacOS version has only been compiled for Apple Silicon — less of an issue than it used to be — and the web version naturally can’t get access to hardware for, e.g., serial ports, so it is somewhat more limited than a full install. There’s a second ARM build for Raspberry Pi along with the ubiquitous x86, but the project is open source, so if you really want to run this on an UltraSPARC system, you are welcome to compile it there. That said, this is a beta version, and the dev is actively looking for problems — so give it a go and let them know.

This isn’t the only open source BASIC out there — even Microsoft released their source code, at least for the 6502.

Thanks to [UglyMike] for the tip!

A black pickup sits in front of a snow-capped mountain range in the background. It has a white camper shell with a sci-fi looking "01" emblazoned on the side in black text. An orange, wedge-shaped tent pops up above the campershell and truck roof.

A Pop-Up Truck Camper For Less

July 19, 2026 by 13 Comments

We live in a veritable Cambrian Explosion of camping options, ranging from a tarp on the ground to multi-million dollar RVs. Somewhere around the middle is the pop-up truck camper, but [Further Fabrication] wanted to build his own.

As is often the case, he saw the cool pop-up truck campers on the market, but balked at the cost. To make matters worse, the options out there weren’t really available in his country. After getting a solid set of measurements from the truck and some materials, he set to work.

The most interesting part of this build is probably the aluminum/plywood sandwich [Further Fabrication] chose for building the main structure of the camper shell. While many would’ve chosen a tubing space frame for the build, he decided to sandwich two layers of plywood around plywood beams and large rectangular aluminum tubing. These were affixed with a combination of construction adhesive and screws to create a lightweight yet sturdy enclosure.

The tent portion uses a 600-denier PVC-coated waterproof polyester fabric, sewn with nice YKK zippers, and features large windows with screens for excellent ventilation. The roof consists of two sections of aluminum composite sandwich, and the side panels were made from cutoffs of the roof material. Instead of the standard cam-lock used on most camper shells, [Further Fabrication] chose a solenoid-actuated system and more conventional grab handles.

We’ve covered campers several times, including a solar-powered RV, a truck camper that expands lengthwise rather than up, and several bike-based campers.

Open-Source Mid-Drive E-Bike Motor Has Lots Of Promise, And Hyphens

July 18, 2026 by 26 Comments

[Pedro Neves] has a mid-drive e-bike, but he doesn’t own it — not truly, since he can’t repair the motor unit. For a hacker to be in that position, there are only two options: crack the old one and make it your own, or build your own from scratch. [Pedro] built his own and is open-sourcing it on his website for everyone to play with. Right now, that’s .step files and a BOM, so you’ll need to watch the design/build video on YouTube below to get the full picture.

His choice of a motor from an old battery-powered angle grinder is both thrifty and environmentally friendly, so we approve. His goal of 25 km/h seems like a reasonable speed limit, but may still be too fast for some countries’ regulations— so do check the local rules if you’re going to build this. Making the most of 3D-printed components is also a choice that makes the project more accessible, but don’t worry — the bearing surfaces are all metal. That includes the clutch bearing that will let you pedal home if the battery dies or the motor craps out. Well, unless the printed plastic axle gives up the ghost, but that got replaced with a CNC version, so it’s all good. Unless you’ve got legs like Hercules, it ought to hold.

If that’s not DIY enough, you could always build the motor yourself. This mid-drive is also part of a larger project [Pedro] is working on for a whole cargo bike, as he details in his video, which is a worthy project we’ve seen other examples of before.

Write 2D And 3D Games In Modern MoonBASIC

July 18, 2026 by 8 Comments

One of the major strengths of the BASIC programming languages has always been their no-fuss setup and rich set of commands for operations that would take considerably more work in a bare-bones language like C. MoonBASIC continues this legacy with a BASIC variant optimized for both 2D and 3D game development.

Included in the package are Raylib, Box2D, and Jolt, whose functionality is exposed via over 4,200 commands in their respective namespaces. You can also download a whole IDE package based around VS Code, use it on the command line, or add it to an existing VS Code installation.

Your AI Ham Radio Buddy

July 18, 2026 by 12 Comments

AI chatbots are everywhere these days, and they seem to “know” about everything. But while that is a strength, it can sometimes be a weakness because it isn’t laser-focused on one topic. Not so with this Ham-radio-centric chatbot called HamGPT. The service is clearly built on another GPT engine but understands how to retrieve data from common ham radio sources, such as the FCC database, propagation reports, and the like. It didn’t, however, seem to have access to ham radio-related books, magazine articles, or other “static” data that we could tell.

You do have to sign up for an account, which includes providing your callsign and location. There is a free tier that allows a limited number of queries per day, so you can try it to see if it is useful for you without subscribing.
