The 100u cap is just a power filter for any DC ripple. Can you post pics of your board (both sides)? This is just a LPB-1, so we should be able to solve it pretty quick. If I had to guess I'd say you've got a cold solder joint somewhere.

For PPCB projects you can pretty much get away with a cheapie from Amazon as long as it has some sort of temperature control. I used something like this for my first few dozen projects. That being said, an upgraded iron makes things easier. I now use a Weller WE1010 and like it a lot (was a...

Considering the parts count, it sounds like you've got a bad solder joint somewhere. Can you show pics of the underside of the board? Might be a good idea to reflow suspect joints.

Nice build. I like those hot red wires. Or is that just a lighting trick?

Rat is life. Nice build!

Just about all pedals, at least the ones offered here, take less than an amp

Try an Electra distortion on a breadboard and you see how the forward voltage affects the clipping, volume, and compression with hard clipping diodes. LEDs have higher fV so it sounds more “open” and responsive to dynamics.

Try recalibrating your tester.

Looks like I fried my bluetooth chip with too much voltage by accident. Back to the drawing board.

A 78l05 is what I’ve been using. The only other possibility I can think of is using a coupling capacitor between the Bluetooth and amp, like in pedals between circuit blocks.

So, I decided to ditch the charge pump and just power the amp with my 9v, 1A main supply. On its own plus the LED light bar (same supply) they both work fine. I also have this that I can try as a step down converter to 5V, but there may be some current issues and I'll go back to my idea above...

So, what I think will work is having 2 separate power supplies: the 9v main supply and a rechargeable battery. There's too much cross talk powering the bluetooth and amp on a single supply. The battery will power a switch with LED ring and the bluetooth module. I also have a LED light bar that...

I'm gonna be DIY stubborn about this and not try to "buy" the solution unless I have to. There's gotta be a way to get this going. My 9v supply is an old daisy chain that I may try to take advantage of. This will be my lunch break today. Sigh

Alright. Scratch that. Hooking up a 9v battery to the module via regulator and I get squeaky clean sound. Amp is on a separate supply. Thinking out loud, this is either a current issue (probably not) or cross talk with the amplifier. For the record I tried a DIY amp using a LM386 as per the...

Update I decided on a whim to figure out why the bluetooth module is causing this hum. Tried hooking the module to my bench supply, which is separate from the other supply and there is no issue now. The hum occurs if I use my 9v supply or a battery. Could this just be DC cross talk between devices?

Hey Guys, Not guitar pedal related, per se, but a project I am working on. I've got some pretty good, albeit old, speakers that I'm trying to hook up to a bluetooth transmitter and amplifier that I'm going to stuff into a 125b enclosure (along with other items making this a utility box) and...

I wish I had friends that brought me pedal parts

The Orange Guy will change his mind every day. My advice is to just pull the trigger on a Tayda order (not $800 worth) and just go build for a while until this all blows over. OR Actually go practice guitar.

Awesome. Thank you! I was searching for this for a while...

This question is more for the old timers here during the Fig days (we surely miss him). I remember a few years ago Fig passed around an Electric Ladyland PCB to most of us. I've finally put it together this afternoon and everything seems to work. It was partially put together months ago and left...
