Assembling the Mini Mood Light v1 Kit

The Mini Mood Light is a small interactive and reprogrammable coloured light generator circuit.  The mood light consists of a Texas Instruments MSP430 micro controller connected to two RGB LEDs, four buttons and some supporting components all on a custom circuit board.

A kit with the circuit board and all the required components is available from, along with code and instructions for setting up a suitable Linux development environment.

The process of assembling the Mini Mood Light v1 kit isn't particularly difficult but it can take over 30 minutes depending on your soldering proficiency.

The minimum required tools are a soldering iron, some solder, a side cutters and pliers.  Additional useful tools include a helping hand stand, a multimeter, a soldering iron stand, a solder sucker and some solder wick.
