Project #1 – The AcceleroSynth – Mk1

Apr 3, 2012 @ 15:03


We are finally ready for our first electronics project, The AcceleroSynth. It is an microcontroller-based (Arduino) music synth that is controller by a 3 axis analog accelerometer. It will be both a hardware and a software synth. This is the announcement for the project and in the coming days I will post the BOM (Bill of Material), schematics and Arduino code with the first assembly video. The project will first be assembled on a protoboard, then a soldered version will be built either on a perfboard or on an Arduino ProtoShield. If there is enough demand either a PCB or an Arduino Shield will be built for the project and sold here. More on that later. The first installment on the building of the project should be up on a few days.

Tomorrow’s Video – An Introduction to Microcontrollers

Mar 28, 2012 @ 22:12

I’m hard at work… Actually make that “I think” that tomorrow’s video post will be an introduction to microcontrollers. I will dig some stuff out of the drawers tomorrow and as usual make it up as I go and it will probably be about microcontrollers.

Sleep tight…
