The 28th Annual Chaos Communications Congress just wrapped things up on December 31st and they’ve already published recordings of all the talks at the event. These talks were live-streamed, but if you didn’t find time in your schedule to see all that you wanted, you’ll be happy to find your way to the YouTube collection [...]

Want to monitor how much a wheel has turned in your project? Then you need a rotary encoder! Here’s a way to add rotary encoding without changing the mounting method of your wheels (translated).

With winter upon us, and all the windows shut, [Garfield] and [Socks] can get a little restless. But [Dino] is determined to keep his furry friends entertained through the cold dark months.

[Grenadier] built his very own x-ray machine. He’s no stranger to high voltage – we’ve seen his Jacob’s Ladders and Marx generators. Surely he can handle himself with high voltage and dangerous equipment. With this portable x-ray machine, [Grenadier] has begun overloading Geiger counters. We’re just happy he knows what he’s doing. The key component of [...]

The north end of their facility is home to a huge 15×17 glass block wall that happens to face a well-traveled [...]
If you do a lot of SMD soldering, a reflow oven is the fastest and most efficient way to get all those tiny components attached to your PCB. [Frank Zhao] saw the reflow ovens we featured here over the last few weeks and figured he might as well show off his rig as well. We’re [...]
