Umm, do you have the code and boards you purchased listed anywhere? I am trying to get some bench demo setups and trying to find functional setups with available parts and code has been rather maddening...
I had to hack the Honus code from back in the day to get my setup working and I have a horrible lag issue. I am going to try an alorium board setup, but have to fabricate a custom shield with segregated power for the servos on it so that the alorium setup can uitilize the built-in fpga processor.
The other option is to pursue rewriting everything in circuit python and using a metro m4 express.
I want the cannon and light pieces hashed out before I work on designing my own writeup and build on the bomb gauntlet setup with off the shelf pieces.
