Arduino based DMX flood light

The project I am working on these days is to combine the DMX hard- and software into a DMX controllable flood light.

The main goal for this project is to build a cheap DMX spots so no special parts where used.

Here you see some of the early pictures:

The casing

I bought a cheap 100W Spotlight from a local dealer for less than 3 € and extracted everything from it.

The Prototype

The prototype was build using a breadboard with an Serial Arduino on the back.

This is not a good design because using only 9 LEDs of red, green and blue results only in a low light but it proves that the space in such a small casing is sufficient for the electonics and the layout using MOSFETs. The power supply I used is an external 12 V socket adapter.

The software is the DmxSerialRecv sample sketch that comes with the DMXSerial library.

Here is the final assembled prototype:
