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.

Thank you for the Like of the #FilaMecanum project Kevin.  I apologize for my inner monologue that happened on the chat session.  That was not intended for public consumption.  :)  I do envy the ability to do 'that' though...  Please check out my actual planned submission this year, #P2 - Pick and Place for 3D Printers which is *still* waiting on a Jetson Nano to move forward.

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
