Back in 2016, Michael Diamond had an idea to set up a music and light show using a Raspberry Pi to control LED strings draped around the house. To prove out his concept, he made a prototype seen in the video below.
While interesting, after receiving some feedback that the relays he was using might not be able to hold up to prolonged use, he decided to put the project on the “in progress shelf,” perhaps to be worked on at a later date. Inspiration to return to the project came much later in the form of seeing a Tesla vehicle doing a Christmas light and sound show.
To get around the relay reliability problem, his next iteration uses eight MOSFETs for control of the LEDs. In addition to changing up this switching method, he also added a Pimoroni pHAT DAC to properly output audio signals, and purchased 12V LED strips to use in his demo. This allows everything to run off of a single power supply.
While the needed parts haven’t yet arrived, when complete, it’ll use a 5V power supply for the Pi Zero he’s using, and voltage will be stepped up using a boost converter to power the LEDs.
It may not be able to drive you to work like a Tesla, but the display looks and sounds great in the clip here.
