LEAP#356 PX088A Für Elise Music Chip

Another potted music chip! Figuring them out is half the fun;-)

The PX088A is a simple, nondescript single-tune chip. Found out it plays the main theme from Beethoven’s Für Elise. The recommended configuration turned out to be a battery killer, but I was able to get it working with a few adjustments.

LEAP#355 Snow Flake

When @LuckResistor announced the Snow Flake to the Boldport Club community, I knew I had to join in!

The Snow Flake is an Atmel SAM D ARM Cortex-M0-controlled LED ornament. I’ve just completed building the first Once I have built some more I will be able to experiment with co-ordinated operation, but even a single snowflake makes for an impressive display.
