Overview

These are notes and files relating to the 'Learn To Solder' Robot Badge.This badge kit has been produced to use at events as a simple soldering exercise and promote the hackspace. This badge was based upon a simple flashing LED badge that was seen at UK Maker Faire 2011 in Newcastle. This robot shaped badge was designed by Matt Little based on an idea by Rob Keating from PCB manufacturers, Beta Layout. Beta Layout produced a number of batches of these PCBs for Nottingham Hackspace.

Build Instructions

Parts List - Simple

The simple version of the badge is just an LED wired derectly with a battery. A colour changing LED is used to make it a bit more interesting.
