Wow Suit Gen 3 – Up and Running

Problems listen in the previous entry have been resolved. It seems that I can not push the APA102 strips to run above 5MHz using the Raspberry Pi’s SPI port. That seems to be the maximum before I get noise on the line. 6MHz works as well but you can see some noise on the very end of the block when allot of power is consumed. I think it is a combination of things. but im happy with 5MHZ

 

 

The other issue was the Power Up drain. For now the best forward is to put hardware switches onto each power tap. There are 11 power taps. Ill assign 7 switches on a small perf board that joins all the taps together to the 6 USB power cables. If i start up the sequence sequentially, the LEDs have 0 noise and power on in the OFF state, which is what we want! If i power up all the taps at once, i get a huge whopping bunch of noise and the batteries cut out to protect themselves from overload.
