A homemade 3x20 Watt LED blinder.
A prime example of not so well designed electronics: Switching the primary side of LED drivers with mechanical relays. All electronics are powered by a 230V-5V "phone charger". For reading the DMX signal, an adaptation of the Mathertel design for isolated DMX was used. together with the DMXserial library on the cheapest arduino I could find. Also clearly visible is my terrible woodworking skills around the DIP switch package.
So to conclude, I would not recommend using this project as an example. But o boy, it is bright!
