Title: Glasshole worked great (for about 1/2 hour)
Post by: photon on March 07, 2021, 07:17:58 PM
I finished up my Glasshole build yesterday, got the trimmers set just right and it sounded awesome. I had time to play with it for about 30 min. and everything worked and sounded great.

Today when I plugged it in, it just emits a horrible drone and the LEDs are on steady at full brightness (including the one inside that drives the photocells).

Weird, right? Any suggestions very much appreciated.

Thanks!

Sounds like a grounding issue. Have a look to make sure something fell or shifted and is touching the enclosure. Sometimes when all the solder joints cool down, wackiness ensures. What's going on with lug 6 on the stomp?

What's the little light cover made of?

Thanks, I'll take a close look tonight. As for Lug 6 on the stomp, I don't see what you mean.

It's 3D printed to be a tight fit around the photocells and lined with aluminum tape.

It must have been the angle on the previous photo, it looked bent forward.

Looks like the J1 and IN wires need to be flip flopped.

Looks like the stomp wiring is as per the build doc.

Are you sure you didn't accidentally connect an AC output wall wart to this? A sure fire sign that AC has been connected is when all of the 'lighting' on a pedal shines bright like a Christmas tree  :-\

I agree with Greg, the wiring looks good to me.

Check that your DC input is not shorting on the pot below. I'd recommend using pot covers or electrical tape.
