Fans of Doctor Who with a pechance for synthesizers be happy. Here's a model of a Dalek hacked with an Arduino clone. Kudos to MatrixSynth for this story.
Martin Orman published this video on 30th of December 2016 and describes the project as follows:
"I picked up this Dalek from a car boot sale so it's a bit battered. I installed a synthesizer written onto an ATMEGA 328P chip (Arduino Uno clone that I built) inside. It runs on battery or 9v DC mains adapter in. There are two mono outputs i.e. 3.5mm and 1/4". It's possible to run both outputs together in order to set up two audio channels in your DAW that will create a stereo output. This is recorded into Ableton 9 through a Focusrite Scarlett 18i8 with standard reverb, compression and Reaktor Molekular 'Plagiarism' added to give some additional harmonics."
Martin Orman encourages you to contact him over on YouTube for instructions or to buy one.
