Description
Santa's sequencer badge
After joining to PCB Badge challenge, organized by the Brazillian Computer Engineer and Youtuber Julia, from the channel Laboratório da Julia (Julia's Lab), it was needed to develop a PCB Badge with a Christmas theme. My project idea is to make a simple ornament. Its implementation is made with a Johnson decade counter IC, the CD4017, to create a sequencer. The clock circuitry was made by transistors, creating an Astable Multivibrator.
Update Jan. 27th: The pcb design flaw is now corrected: the transistors ground plane was isolated from the rest.
More about it and a more complete documentation on the Github link.
