During my residency at The Edge I held a series of free DIY interactive chandelier making workshops. Held over period of three wekends, I introduced participants to basic electronics and soldering. I provided a range of building materials, including plastic flowers, beads, plastic toys, cake coolking racks, chains and other sparkly, shiny things. I also provided coloured LED lights, wire and soldering irons, with participants building their own stands of coloured lights.
For this workshop I designed a programmable circuit board that drives the LEDs in the chandeliers. Each board contains an ATTiny85 microprocessor, which can be reprogrammed using the Arduino programming interface. The methods of prgramming the ATTiny was inspired by the work by the High-Low Tech Research Group at MIT Media Lab.
Here is the code for the chandelier circuit:
