Mute Your Microphone While Typing with Hushboard
Yesterday while surfing the ASCII highways of IRC (yes, IRC) a URL linking to a MacOS application scrolled by my screen. Unclack is a small MacOS utility which silences the microphone of the user when they’re typing. The purpose is to prevent the noise of typing being passed through to other participants when on a…

A USB Fan Controller that now works under Linux

IoT Nixie Tubes
Every day I make a cup of coffee, organize a list of the things I want to do that day, and try to work through it. Every time I finish one of the tasks, I mark it as complete. By the end of the day, ideally there are no things left on the list, but if there are, I’ll move them into a backlog and start fresh the next…

The World's current and next Innovations depend on a single country, Taiwan
The world’s current and next innovations depend on a single country: Taiwan. It’s probably one country you might never hear about, or perhaps confuse with its neighbor, Thailand, or even think it’s a part of China.

Pentium on a 386 Motherboard
I was wondering what would be the ultimate upgrade for my 386 motherboard. It has a soldered-in 386 CPU, an unpopulated 386 PGA socket, and a socket for either a 387 FPU or a 486 PGA. It might even be compatible with a Weitek processor, though I’m not entirely certain. There’s also a possibility that it has a…

The idea is not new, a quick google search showed that it was indeed possible but you need a special adapter for these microscope lenses. The adapter is called “RMS…
