Terrible title sorry. I’ve noticed that amongst the the switch pads on PCBs, there is usually one square pad (DPDT etc). Although I note that Pedal PCBs ones don’t have this, only others. What is the reasoning for having a square pad? The orientation of the switch doesn’t matter? Although I’ve...

Hi all, I'm looking to streamline the wiring process and so want to board mount my power jacks. All I can find are square / rectangular ones (https://www.taydaelectronics.com/hardware/dc-power/dc-power-jack-2-1mm-barrel-type-pcb-mount.html), but this creates a problem when drilling...

Perfect. Answers everything. A legend. Appreciate your time. Thanks again

Hey @Chuck D. Bones - Firstly, thanks for your work here. Learn something new each time. I'm working through your notes / comments above and got a couple of queries. You've noted: Replace R16 with a jumper, use either 20K or 22K for R6. Makes no difference. Then clarified in a later comment...

Hi all, Designed a few pedals in Eagle and got them to work pretty well, but these were basic and relatively low part count. However, I have drawn up something that is much larger and I've lost the confidence that I have everything covered. Has anyone used a service that can check over these...

Not that this is in anyway helpful, but no, I haven't managed to fix it. I've put it on the shelf and moved onto other projects to build back some enthusiasm in tackling it

It wouldn’t be an issue with the chip specs I’ve used? I note that I’ve used an lm324N and a 833N. Whereas the build docs call for lm324A? I did a quick google prior to using them and didn’t see anything that I thought would be a problem, but I’m happy to be wrong

That’s a green led that was connected to pin 7 in order to solve the noise issue. There is a good thread where a user solved the noise issue by connecting these up. I thought that was the problem initially, so I clipped the connection to pin 7, but have left the led connected to ground in the...

Thanks all. Apologies for the delay in replying, had work. Appreciate the responses. I’ve clipped D2 and D3 to remove them from the circuit and can confirm that @PedalPCB is correct and isn’t the issue here. I’m going to learn how to use a multimeter and report back. Might take me a hot...

Hi all, Tearing my hair out with this one. I’m only getting clean signal when engaged. I’ve switched out all the ICs and checked over too many times. Is there anything that you guys can see that I’m missing? Thanks for looking.

All, Interested in building up a promethium with no potentiometers. They are only going to be dimed anyway. Is this as simple as just soldering a resistor that corresponds with the potentiometer value? Which pads do I connect the resistor too if this is the case (there being 3)? Thanks for any...

Hey all, I’ve been looking a at few pedal designs and it seems that some designers have used non-polarised electrolytic caps in their circuits. To my uneducated eyes, it looks as though a normal polarised cap would would in it’s place, but obviously the designer would use a common component if...

Hi all, I’ve been looking at projects using LDRs and want to understand their function and effect on the actual sound. Why use these instead of standard resistors? Do they have a variable effect? How does this work if the light from the led is constant? Sorry, bit of a ramble, I love the...

Have you had a chance to draw this up yet @PedalPCB?

*BUMP* Hey man, any update on the version with the order switcher? Sorry, know you are crazy busy. Just want to make sure this doesn’t get buried. Cheers
