SP0256A-AL2 Sings the Twelve Days of Christmas

Partly prompted by a programming challenge by Futzle on Mastodon, I thought it might be interesting to try to get my Arduino and SP0256A-AL2 to sing the Twelve Days of Christmas. https://makertube.net/w/diBkzrhkh3tekAPBhGzrVj Warning!

MiniDexed Raspberry Pi IO Board V2 Design

My two MiniDexed PCBs were some of the earliest ones I made and so I've wondered about revisiting them for a while now. This is a respin of the SSD1306 version of the IO board that is, hopefully, slightly nicer to build a case around! Here is the link to the original PCB: MiniDexed Raspberry … Continue reading MiniDexed Raspberry Pi IO Board V2 Design
