Tayda used to be pretty fast, but I've been averaging 4-5 weeks for an order of ~8 powdercoated enclosures. The last lot were stuck on...

I still have no idea what you mean by LDO inverter. Can you please link to what you are talking about?

$5 is for unregulated 12v in (as this is a more common commercial voltage range). It's $15 for 2w, regulated, 9v in. What do you mean...

Again - they are literally the same thing in 99% of pedals. Referencing an op-amp to vref instead of ground has the function of creating...

The question shouldn't be what is requiring a bipolar supply or not because they both do - one using a dual supply, and one using a...

This is switching power supply PCB design 101 - you tie the separate grounds back at a singular point (preferably the DC jack, or at the...

Finished. I've added the PCBWay direct output and a BOM - everything is pretty straight forward and easily available. It does...

Nothing substantial to add except if you do take "better employee" courses, make sure you get paid for them. If they expect you to do...

Almost done - just need to finalise a few things to make it as easy/cheap to make as possible. Using a fully isolated onboard switcher...

All wire has resistance, and if it has resistance it will have an associated voltage drop. A meter of 24AWG has a total resistance of...

It's basically just the two halves of a Animato split into controllable sections (as part of me messing around with dual PCBs) with some...

I think it's like the tone wood debate - does it make a difference? Sure. Are there a million other things going on that could have as...

Slots aren't 100% accurate to the original, but it's close enough for government work. Document is scaled to the correct size; align the...

I know this is a really, really old post - but did you ever discover any other series of CMOS chips that are quiet? I'm pushing my luck...

Your component designators don't match the current build documents. Can you please confirm which diodes/resistors you are talking...
