LED driver utility board - free simple OSH design

[electrosonic]

I made a small 1/2" x 1/2" board to add an led indicator to a project. They cost $1.25 for three boards from OSH Park, maybe some will find this useful.  The idea is you mount the led then attach the board to the led, I think the board is small enough so it won't be a problem. Not verified - so please let me know if I screwed something up - use at your own risk.

This turns the LED on when the signal goes high. I haven't checked but you could probably rewire the same board with a PNP so the LED lights when the input goes low.

So the LED lights up when you are playing and turns off when you are silent?

I'm not sure if it would be bright enough with guitar signal - I think maybe the OP is refering to a 5V source?

I guess I wasn't clear enough about what this is for. It is not meant for a guitar signal, it is a small add-on board for adding LED status.

It could be used to add a LED to a LFO to show its rate (without loading down the LFO much).

Or add an LED to a compressor to show when it is compressing

In another thread I was looking at my ancient BOSS PH-1, the LED doesn't toggle like all modern pedals (it only lights when the footswitch is pressed). I can use this and tap into the flip flop have the LED status behave like modern pedals.

Nothing new here, but it is simple and small and cheap.
