Things I've Built


This is a Java application (and framework API) for interacting with bowler devices. It makes it easy to interact with the devices and quickly develop hardware.

Michigan J Skeleton

This was a fun halloween project from 2011 where i added a layer to the DyIO where you can load a song and synchronize motions to that music. I made a skeleton sing and dance.


This is a Dynamic I/O controller. It used the bowler protocol to abstract microcontroller functions across a communication link. All features can be requested from a host application and used through the same interface.


This is the first robot to use the Bowler CNC controller. It is a closed loop control system running each axis. We have increased the possible precision per axis while cutting the cost down to 1/4 of an equivalent stepper.

I'm sure you have figured out how to squeeze every last clock cycle out of you PICs over th years but this might be of interest
