Figured out why my EV controller power light doesn’t come on. It would seem I soldered the LED in backwards…ugh.
Beyond that, I can program the chip and fuses, and it would seem that it’s communicating via serial, but I’m not getting any feedback to RTD Explorer.
This was a triumph…no, it really was. After this long dark age, there’s something to report and should be (slightly) more regular updates from here on out.
I managed not too long ago to finally get a programmer kit from Adafruit to build a USBtinyISP programmer for loading code onto the ATMega168 microprocessor that is the ‘brain’ of our EV motor controller. After a little research and some trial and error, I think I’ve got our control board programmed.
We’ve got a copper bus bar coming on Tuesday that’ll get cut to make the 3 main bus bars of the controller – 3/8″ x 3/4″ x 45 1/2″ long, 99.99% pure electrical conductive copper. It’ll get cut in thirds to make the 3 bus bars of the controller. Once all this is up and ready, we’ll only need a capacitor bank to begin testing the controller on the go-kart!
