Last week, we examined a Doom port for the venerable Atari ST. As is so often the way with this thing, one netted another, and [Steve] wrote in to inform us about a different version under the name DOOM8088ST. The port is so named because it’s based on Doom8088, which was originally written for DOS […]
There are lots of different types of microphone, with the ribbon microphone being one of the rarer ones. Commercial versions are often prized for their tone and frequency response. You can make your own too, as [Something Physical] demonstrates using a packet of chewing gum. Yes, the ribbon in this microphone was literally gained from […]
[Dmytro] was able to lay his hands on a InfiRay T2S+ camera. It’s a capable thermal imaging unit that comes at a cheaper price than many of its rivals. [Dmytro] decided to pull it apart to see what makes it tick, and he discovered a few interesting things along the way. Like so much modern […]
Don’t you hate it when making your DIY X-ray machine you make an uncomfortable amount of ozone gas? No? Well [Hyperspace Pirate] did, which made him come up with an interesting idea. While creating a high voltage supply for his very own X-ray machine, the high voltage corona discharge produced a very large amount of […]
Garage doors! You could get out of your vehicle and open and close them yourself, but that kinda sucks. It’s much preferable to have them raise and lower courtesy some mechanical contrivance, and even better if that is controlled via the web. [Juan Schiavoni] shows us how to achieve the latter with their latest project. […]
Some things are so common you forget about them. How often do you think about an ordinary resistor, for example? Yet if you have a bad resistor, you’ll find it can be a big problem. Plus, how can you really understand electronics if you don’t know all the subtle details of a resistor? In the […]
Once upon a time, typing “www” at the start of a URL was as automatic as breathing. And yet, these days, most of us go straight to “hackaday.com” without bothering with those three letters that once defined the internet. Have you ever wondered why those letters were there in the first place, and when exactly […]
Vintage hi-fi gear has a look and feel all its own. [ThunderOwl] happened to be playing in this space, turning a heavily-modified Technics stereo stack into an awesome neo-retro PC case. Meet the “TechnicsPC!” This is good. We like this. You have to hunt across BlueSky for the goodies, but it’s well worth it. The […]
If you’ve dealt with reactance, you surely know the two equations for computing inductive and capacitive reactance. But unless you’ve really dug into it, you may only know the formula the way a school kid knows how to find the area of a circle. You have to have a bit of higher math to figure […]
