[Rick] had a problem. His garage refrigerator was tasked with a critical duty—keeping refreshing beverages at low temperature. Unfortunately, it had failed—the condenser was forever running, or not running at all. The beverages were either frozen, or lukewarm, regardless of the thermostat setting. There was nothing for it—the controller had to be rebuilt from scratch. […]
Connected devices are ubiquitous in our era of wireless chips heavily relying on streaming data to someone else’s servers. This sentence might already start to sound dodgy, and it doesn’t get better when you think about today’s smart glasses, like the ones built by Meta (aka Facebook). [sh4d0wm45k] doesn’t shy away from fighting fire with […]
Halloween is about tricks and treats, but who wouldn’t fancy a bit to drink with that? [John Sutley] decided to complete his Halloween party with a drink dispenser looking as though it was dumped by a backstreet laboratory. It’s not only an impressive looking separating funnel, it even runs on an Arduino. The setup combines […]
Generally people equate the Arduino hardware platforms with MCU-centric options that are great for things like low-powered embedded computing, but less for running desktop operating systems. This looks about to change with the Arduino Uno Q, which keeps the familiar Uno formfactor, but features both a single-core Cortex-M33 STM32U575 MCU and a quad-core Cortex-A53 Qualcomm […]
Do you remember the movie WALL-E? Apparently, [Leviathan engineering] did, and he wasn’t as struck by the title character, or Eva, or even the Captain. He was captivated by BURN-E. His working model shows up in the video below. We’ll be honest. BURN-E didn’t ring a bell for us, though we remember the movie. He […]
[WhiskeyTangoHotel] wrote in with his newest clock build — and he did warn us that it was minimalist and maybe less than useful. Indeed, it is nothing more than a super-cheap ESP32-C3 breakout board with an OLED screen and some code. Worse, you can’t even tell the time on it without pointing your cell phone […]
When we see an extremely DIY project, you always get someone who jokes “well, you didn’t collect sand and grow your own silicon”. [Patrícia J. Reis] and [Stefanie Wuschitz] did the next best thing: they collected local soil, sieved it down, and fired their own clay PCB substrates over a campfire. They even built up […]
Strictly speaking, a Theremin uses a pair of antennae that act as capacitors in a specific R/C circuit. Looking at [aritrakdebnath2003]’s MIDI THEREMIN, we see it works differently, but it does play in the manner of the exotic radio instrument, so we suppose it can use the name. The MIDI THEREMIN is purely a MIDI […]
The Arduino ecosystem is an amazing learning tool, but even those of us who love it admit that even the simplified C Arduino uses isn’t the ideal teaching language. Those of us who remember learning Pascal as our first “real” programming language in schools (first aside from BASIC, at least) might look fondly on the […]
