Robin Price
, a colleague in the SARC PhD lab (and co-conspirator in making acid-house & improv) has started a new blog documenting his work. Currently the blog shows his work on making an Arduino-controlled DAC, allowing you to send smooth (non-PWM) voltages into your 303, x0x-box, or other voltage controlled synth. The video demo is shown above, and the blog can be found here:
