MAGNUM OPUS KEYBOARDUS, OR BUILD AD INFINITUM?

It happens to pretty much everyone who gets into keyboards. No commercial keyboard can meet all your needs, so you start building them. Use them a while, find problems, build a new keyboard to address them. Pretty soon you think you have enough user experience to design the perfect keeb — the be-all, end-all magnum opus clacker you can take to the grave. This time, it happened to [aydenvis]. We must say, th ...

A WALKING ROBOT WITH A SINGLE SERVO

We’ve all been there — you see somebody do something cool on YouTube and you just have to give it a go. For [lonesoulsurfer], the drop-everything-and-build happened to be a little four-legged walker robot that runs on a single servo. Though it may be simple, there really is nothing like seeing a robot you created take its first steps. [lonesoulsurfer]’s walker is made mostly from scrap aluminium and other s ...

OPEN-SOURCE ROBOTIC ARM FOR ALL PURPOSES

A set of helping hands is a nice tool to have around the shop, especially if soldering or gluing small components is a common task. What we all really want, though, is a robotic arm. Sure, it could help us set up glue or solder but it can do virtually any other task it is assigned as well. A general-purpose tool like this might be out of reach of most of us, unless we have a 3D printer to make this open-sou ...

USB BELL RINGS IN CUSTOM TERMINAL

Old TeleTypes and even typewriters had bells. Real bells. So that ASCII BEL character is supposed to make an honest to goodness ringing sound. While some modern terminals make a beep from the computer speakers, it isn’t the same. [Tenderlove] must agree, because the turned a Microchip USB to I2C bridge chip into a HID-controlled bell. The only problem we see is that you have to have a patch to your terminal ...

ARDUINO TAKES CONTROL OF DEAD BUSINESS CARD CUTTER

It’s a common enough situation, that when an older piece of equipment dies, and nobody wants to spend the money to repair it. Why fix the old one, when the newer version with all the latest bells and whistles isn’t much more expensive? We all understand the decision from a business standpoint, but as hackers, it always feels a bit wrong. Which is exactly why [tommycoolman] decided to rebuild the office ...

SURFBOARD LED STRIPS LIGHT UP THE WAVES

Surfing is an activity predominantly enjoyed during the day, primarily for reasons of warmth and water safety. Of course, if you prefer to carve the waves at night, you might enjoy the latest project from [Moritz Sivers] – a surfboard kitted out with motion-reactive LEDs. The build consists of a regular surfboard, with a channel cut around the perimeter into which WS2812B LED strips are glued. Powered by a ...

UPGRADED INFOTAINMENT OPTIONS ON A 14 YEAR OLD MERCEDES

It used to be that upgrading a car stereo was fairly simple. There were only a few mechanical sizes and you could find kits to connect power, antennas, and speakers. Now, though, the car stereo has interfaces to steering wheel controls, speed sensors, rear-view cameras, and more. [RND_ASH] was tired of his 14-year-old system so he took an Android head unit, a tablet, and an Arduino, and made everything work ...

CODESPACES FOR EMBEDDED DEVELOPMENT

We can sympathize with [Benjamin Cabé]. He has a lot of development boards and it has become painful to maintain the many toolchains for each board. We’ve also suffered from upgrading one tool breaks another tool in some obscure way. His solution? Use Github Codespaces which you can get early access for beta testers. The idea is that you can spin off a container-specific to a GitHub repository that has all ...

A MOBILE PHONE FOR THE PULSE DIAL GENERATION

One of the useful side effects of the ubiquitous availability of cellular network data modules is that they can be used to create custom mobile phones. It’s surprising in a way that we don’t see as many of these projects as we’d expect, but by way of redressing that deficiency we’re pleased to see the work of [Proton Gamer], who has taken a vintage rotary dial phone and upgraded it with an Arduino and GSM s ...

HEX MATRIX CLOCK IS SPELLBINDING

Just when we think we’ve seen all possible combinations of 3D printing, microcontrollers, and pretty blinkenlights coming together to form DIY clocks, [Mukesh_Sankhla] goes and builds this geometric beauty. It’s kaleidoscopic, it’s mosaic, and it sorta resembles stained glass, but is way cheaper and easier. The crucial part of the print does two jobs — it combines a plate full of holes for a string of addre ...

THIS TUBE PREAMP HAS A NIXIE VOLUME DISPLAY

The pursuit of audiophile hi-fi is one upon which many superlatives and perhaps a little too much money are lavished. But it’s also a field in which the self-builder can produce their own equipment that is as good or often better than that which can be bought, so it provides plenty of interesting projects along the way. [Justin Scott]’s tube preamplifier is a great example, with its novel use of a pair of N ...
