README

This project is subject to the CERN Open Hardware Licence
Electronic Load Controller Design is available here.
This repository is a direct implementation of the ludens.cl ELC circuit.
The Schematic and Printed Circuit Board have been produced in KiCad. The Printed circuit board has been routed single-layer so it may be possible to etch your own easily enough. Otherwise it can be made very cheaply. There's plenty of improvements that can be made to the design, and there's plenty of optimisations for the PCB layout too if you fancy changing things up.
To use this Load Controller you'll need a way to program the PIC microcontroller and you'll have to use the code available on the lidens.cl website. Perhaps they can make a binary available for anyone to use without them having to use the PIC basic compiler.

Questions
How big is the Elc ludens.cl PCB?
It measures 100 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Elc ludens.cl use?
52 parts, built around the PIC16F628A-I/P and BC337. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Elc ludens.cl KiCad files?
From the BrianSidebotham/elc repository on GitHub, at the commit this page was made from: the board is elc-ludens.cl.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Elc ludens.cl design in my own project?
Its repository states no licence, so its author keeps all rights: ask BrianSidebotham before reusing the design.
