I’ve been talking to a friend about the method of doing the LED light up on activation mod via the hex inverter.
According to him, there is another easier method that will work just as well, and potentially not need an external battery.
He’s good with electronics and building analog circuits, but not familiar with controller pcbs, and I’m not versed enough electronics or building circuits to give him the specifics of how the Cthulhu or 360 pad works. As far as he knows the pad should be able to power the LEDs on it’s own via the USB, but maybe someone here knows otherwise.
Basically his method uses PNP transistors and a couple resistors of specific values instead of the hex inverter.
What I’m hoping is that some of the electronics gurus on the board will let me know if this method would work.
He would like to know what the benefit of using the hex inverter would be as opposed to using PNP transistors which can be easily found at Radioshack (while the inverters need ordered for most people).
Here is the schematic:
Any thoughts or input would be appreciated. Thanks.
