This is my last log entry prior to the close of the contest. But not my last entry in this project by any means! I've learned a lot, but have more to do! Video summary follows.

I didn't get the control scheme refined, or have time to try and implement the capacitive touch buttons. But I'm satisfied with the results because there is a lot of promise. The fact that it drives pre-made motors nicely means that I need some refinement in the motor construction on the board. I have ideas to improve that. But I'll need to step away from active work on this until later this fall. Other projects call, but it has been a blast bringing this one to life in a hurry!

Unfinished business:

• Ensure adequate bulk power storage for motor pulses.
• Ability to burn 328PB boot loader after assembly.
• Capacitive touch button library and testing.
• Hall sensor feedback testing.
• Analog comparator feedback testing.
• Reduce overall thickness even more.
• Optimize PWM pin usage to allow high frequency without affecting Arduino delay() and millis().
• Optimize control algorithm.
• Test delta winding configuration.
• Clean up the code and implement a simple switch/case based state machine.
• Test R/C PWM input signal mode, use the EEPROM for calibrations.
• Add library to play music through the coils.
• Add LEDs to visualize current flow and direction in the output phases.

If you are interested in collaborating and/or remixing it to make it your own, I'd love to hear from ya!
