David spends a lot of his free time tinkering with various music technology- here are a few examples. Currently he’s working to restore an old 70’s Conn organ with a leslie speaker that he found for free.

David has also created a small drum pad and MIDI trigger using an Arduino. David’s control program includes hysteresis. While he uses this drum pad when he plays, he’s still working to evolve the solution into something more feature-rich.

Additionally, David has recently built a group of small speakers for testing and prototyping new system designs. In the first picture, you can see an early experiment with port length and turbulence. In the second picture you may notice some white-out on one of the speakers— this was used in concert with a laser measurement system to obtain its Thiele/Small parameters, so that David could model these transducers and their enclosures in Spice.
