[joppedc] wrote in to let us know that the Formula 1® season is coming to an end, and that the final race should be bangin’. To get ready, he built this ultra-sleek logo light box last week that does more than just sit there looking good, although it does that pretty well. This light box […]
USB PD is a fun protocol to explore, but it can be a bit complex to fully implement. It makes sense we’re seeing new stacks pop up all the time, and today’s stack is a cool one as far as code reusability goes. [Vitaly] over on Hackaday.io brings us pdsink – a C++ based PD […]
Here’s a fun rabbit hole to run down if you don’t already have the RP2040/RP2350 PIO feather in your cap: how to serve data without CPU intervention using PIO and DMA on the RP2350. If you don’t know much about the RP2040 or RP2350 here’s the basic run down: the original Raspberry Pi Pico was […]
Have trouble sleeping, or getting to sleep in the first place? You’ve no doubt heard of white noise machines, but know it would be much cooler to make your own. Enter Noise Maker, a DIY sound sculpture by [optimus103733], who wanted to learn something in the process of creating. The best thing about this sound […]
Once upon a time, owning a calculator watch was the epitome of cool. Well, for a very specific subset of the population with our own definition of “cool” anyway. The only thing cooler than wearing a calculator watch? Making a calculator watch, of course! If you do it as part of developing your own SDK […]
When the iconic “Boing Ball” first debuted 40 years ago, it was a wonder to behold. There was nothing like it in the home compuing world upto that time, and it showed that Commodore’s new “Amiga” was a powerhouse sure to last the test of time. Forty years later, the Amiga as we knew it […]
Whenever there’s a superlative involved, you know that degree of optimization has to leave something else on the table. In the case of [PegorK]’s f32, the smallest ESP32 dev board we’ve seen, the cost of miniaturization is GPIO. There’s only one GPIO pin broken out, and it’s pre-wired to an LED. That’s the bad news, […]
Some people may remember the joys of trying to boot Linux on an 8-bit AVR microcontroller, which was an absolute exercise in patience. In comparison [He Chunhui]’s Tiny386 emulator running on an ESP32-S3 MCU is positively zippy when it boots and runs Windows 95. The provided video (also embedded below) makes clear that while you […]
WiFi-enabled ‘smart’ light bulbs are everywhere these days, and each one of them has a microcontroller inside that’s capable enough to run all sorts of interesting software. For example, [vimpo] decided to get one running a minimal Minecraft server. The Bl602-equipped board inside the LED lightbulb. (Credit: vimpo, YouTube) Inside the target bulb is a […]
Over on YouTube, [Ben Eater] pursues that classic 8-bit sound. In this video, [Ben] integrates the MOS Technology 6581 Sound Interface Device (SID) with his homegrown 6502. The 6581 SID was famously used in the Commodore line of computers, perhaps most notably in the Commodore 64. The 6581 SID supports three independent voices, each consisting […]
