LEAP#362 H-83A 12 song music chip
The H-83A is yet another music chip, this time programmed with 12 tunes. I haven’t figured out all the songs, but they sound like classic Chinese folk tunes.
This chip requires very minimal external components (resistor, switch and power), but volume is decent in all it’s 8-bit wonder!

LEAP#361 128x128 TFT LCDs
I dug out a 1.44 inch 128*128 SPI Color TFT LCD Module from my parts drawer as a possible display for a project I’m working on.
First .. put it to the test and try a couple of Arduino libraries.

LEAP#360 TL431 Shunt Regulator
The TL431 Precision Programmable Reference is a cheap and easily adjustable shunt regulator. The standard grade offers a reasonable 2% reference voltage tolerance.
In this mini-circuit I am testing the common application as a shunt regulator/reference voltage e.g. for use in power supplies.

LEAP#359 HS-088 Effects Chip
Just another audio effects chip. this time a simple dorbell effect. The effect is very similar to - and not any more pleasant! - than the kind of effect you can get with common two-tone 555 circuits.
