Build and test an MC34063-based boost converter.

Build

Notes

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 but now available from many sellers on aliexpress, ebay etc.

It has a fixed converiguration to boost 5V in to 12V out.

This page is a web-friendly rendering of my project notes shared in the LEAP GitHub repository.

LEAP is my personal collection of electronics projects, usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting (IMHO!).

The projects are usually inspired by things found wild on the net, or ideas from the sources such as:

Feel free to borrow liberally, and if you spot any issues do let me know. See the individual projects for credits where due. There are even now a few projects contributed by others - send your own over in a pull request if you would also like to add to this collection.
