We aren’t sure what [theglassman] is working on, but based on his recent projects, we think it is probably something interesting. He’s been decapping ICs, growing oxide on silicon substrates, and has built a tube furnace capable of reaching 1200 °C. What would you do with something that can melt cast iron? We aren’t sure, […]
Often, we face tedious tasks with no way around them. Sometimes, you just have to grit your teeth and push through. But small tweaks can make the onerous task a bit easier to handle. [James Bowman] sent in his latest quick project that helps him fold small boxes more efficiently. To fulfill orders on his […]
By virtue of its triple bond, acetylene burns hotter than any other common hydrocarbon when mixed with oxygen, but it isn’t the only flame hot enough for welding. With the assistance of a homemade oxygen concentrator, [Hyperspace Pirate] was able to make a natural gas torch that melts steel, even if welding with the torch […]
CRTs don’t last forever, and neither do the electronics that drive them. When you have a screen starting to go wonky, then you need a way to troubleshoot which is at fault. A great tool for that is a pattern generator, but they’re not the easiest to come by these days. [baritonomarchetto] needed a pattern […]
Let’s face it, nobody likes scrubbing, but what option do you have? You can’t exactly break out the grinder to clean off the remains of last nights dinner… right? Well, maybe not a grinder, but thanks to this hack by [Markus Opitz], you can use an oscillating tool. It’s a simple enough hack: [Markus] modeled […]
As is regrettably typical in the cordless tool world, Milwaukee’s M18 batteries are highly proprietary. Consequently, this makes them a welcome target for reverse-engineering of their interfaces and protocols. Most recently the full diagnostic command set for M18 battery packs were reverse-engineered by [Martin Jansson] and others, allowing anyone to check useful things like individual […]
Over on his YouTube channel our hacker [Jerry Walker] repairs a Tektronix 577 curve tracer. A curve tracer is a piece of equipment which plots I-V (current vs voltage) curves, among other things. This old bit of Tektronix kit is rocking a CRT, which dates it. According to TekWiki the Tektronix 577 was introduced in […]
When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they can reach extremely fine precision when paired with external feedback. The micro-manipulator is made of a mobile platform supported by three pairs of parallel linkages, each linkage actuated by […]
[BPS.space] takes model rocketry seriously, and their rockets tend to get bigger and bigger. If there’s one thing that comes with the territory in DIY rocketry, it’s the constant need to solve new problems. Coating the inside of a tube evenly with a thick, goopy layer before it cures isn’t easy. One such problem is […]
