Introduction The goal of today’s workshop is to design and assemble a printed circuit board (PCB) which takes the form of a magpie with a blinking eye. Once assembled, the add-on will plug into your badge and scare everyone within swooping distance whilst reminding them that Birds Aren’t Real. By the end of the workshop you’ll have learnt how to design a schematic and layout a PCB using KiC...

On your bPod, you’ll find a tools menu which provides a way to interface with a number of common embedded protocols. The digital explorer board in combination with a logic analyser provides a way to see what these signals look like, and hopefully provide a greater understanding of the protocols used in modern electronics.

Good value for money soldering iron: https:/...

Two months ago I was sitting at home, browsing Discord, and see this screenshot posted by Laser Ninja. For those who haven’t seen it before, Wombat is a 200ish% percent keyboard designed by Jono, and looks something like the below. After a few messages trying to figure out the feasibility of handwiring up such a monstrous keyboard, and offers of help from Rory and Ant, I replied to Jono...
