The Digital Mermaid | Ep. 92 - The Motor Spins! @TheDigitalMermaid | Uploaded February 2024 | Updated October 2024, 5 hours ago.
Wow, ok, so this is a lot! It took a LOT more work than expected, but the motor is finally under my own control!
The Kelly KLS-72100N, Golden Motor 10kw BLDC, and my own home brew (with your help!) arduino-based helm controls are all talking and working together. It's been a slog, but holy moly have I ever learned a lot. ^_^
We use MCP4725 12-bit DACs to send voltages to the controller, and a TI ULN2003a Darlington transistor array to flip the switches going to the controller. I also chase down a voltage issue that turns out to be a really dumb oops on my side.
