[Samcervantes] wanted a cyberdeck. Specifically, he wanted a Clockwork Pi uConsole, but didn’t want to wait three months for it. There are plenty of DIY options, but many of them are difficult to build. So [Sam] did the logical thing: he designed his own. The Bumble Berry Pi is the result. The design criteria? A […]
If you’re familiar with electrical slip rings as found in motors and the like you’ll know them as robust assemblies using carefully chosen alloys and sintered brushes, able to take the load at high RPM for a long time. But not all slip ring applications need this performance. For something requiring a lot less rotational […]
Despite the best efforts of modern medicine, Huntington’s disease is a condition that still comes with a tragic prognosis. Primarily an inherited disease, its main symptoms concern degeneration of the brain, leading to issues with motor control, mood disturbance, with continued degradation eventually proving fatal. Researchers have recently made progress in finding a potential treatment […]
Ever get to the train station on time, find your platform, and then stare at the board showing your train is 20 minutes late? Bay Area Rapid Transit (BART) may run like clockwork most days, but a heads-up before you leave the house is always nice. That’s exactly what [filbot] built: a real-time arrival display […]
If you have a Nest thermostat of the first or second generation, you probably noticed it recently became dumber. Google decided to pull the plug on the servers that operate these devices, turning them into — well — ordinary thermostats. Lucky for us [codykociemba] has been keeping up with various exploits for hacking the thermostat, […]
The arrival of cheap thermal printer mechanisms over the last few years has led to a burst of printer hacking in our community, and we’re sure many of you will like us have one knocking around somewhere. There are a variety of different models on the market, and since they often appear in discount stores […]
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 […]
Years ago, no math education was complete without understanding how to compute a square root. Today, you are probably just reaching for a calculator, or if you are writing a program, you’ll probably just guess and iterate. [MindYourDecisions] was curious how people did square roots before they had such aids. Don’t remember? Never learned? Watch […]
Just because you are paranoid doesn’t mean people aren’t out to get you. Do you think your soldering iron is after you? Well, [nanofix] asks (and answers): Is My Soldering Iron Dangerous? He has a look at his cheap FNIRSI soldering station and measures a “phantom voltage” of nearly 50 volts AC across the tip […]
