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.

LEAP#358 MC34063 Boost Converter Kit
The MC34063 is a monolithic DC-to-DC switching controller that can be adapted to step-down, step-up and inverting applications with a minimum of external components.
This module is a very cheap kit designed by ICStation ICSK034A. It has a fixed converiguration to boost 5V in to 12V out.

LEAP#357 The Monarch
The Monarch is another beautiful electronic “bug” from the Boldport Club. As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub
The Monarch joins The Lady and The Gent in the Boldport Bug series. They are all exceptionally beautiful boards and make a nice display piece..
