LEAP#292 H823 Audio Effects Chip
Potted music chips! Figuring them out is half the fun;-) The H823 chip arrived in kit and so far I have been unable to find a source for the music chip alone, or indeed anything approximating a datasheet. But after a bit of tinkering, I was able to get it sussed and control it in all its 1-bit glory.. As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub

LEAP#291 CD4060 Music-Light Kit
Learning how to use the CD4060 14-Stage Ripple Carry Binary Counter by building a music/LED-effects kit. I’m not sure what you would actually use this for, but it is an interesting demonstration of the CD4060 14-Stage Ripple Carry Binary Counter.

LEAP#290 The Boldport Club PissOff
The PissOff project was a great opportunity to play with hot-air reflow in a neat circuit involving an ARM Cortex M0, audio amplifier, and an SD card. As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub

LEAP#289 Voltmeter-Ammeter LED panel module
This combined voltmeter-ammeter panel-mount module is a decent unit if you don’t need more precision than ±0.1V/±0.01A.
It did take a bit of reverse-engineering and experimentation to get it calibrated, but once done the accuracy
stays true within 1% over the full range.
