Hi all,
Just pondering how best to approach this; I have created something of a patchbay for a mixer, and I have a bunch of effects that are essentially very simple stompbox and guitar pedal circuits - single transistor boosters, blenders, fuzz etc
I have the capacity to have perhaps 10-20 of these circuits (I plan to build a few more complex ones alongside the simple stuff) so that I can patch and chain different effects and experiment with sounds. They're generally standard 9v - some might be 18v for more headroom. I've put a little 2 pin 9v/gnd header on each board so I can just plug it in.
I need a way to power these efficiently, keeping things clean and quiet as much as I can. I'm thinking I either make a supply from scratch - something that will deliver 9v to each effect, and I could utilise charge pumps to step up to 18v for circuits that need it. I'm thinking a very simple Eurorack-style busboard that I can feed from a single supply then distribute everything from there.
What I'm unsure about is how best to go about making something like that from scratch - whether things need to be 'isolated' or whether effctively daisy-chaining a bunch of circuits in such a way will be an issue. My other option would be to go out and buy a pre-built guitar pedal psu and just gut and modify it to use my 2 pin board connectors instead of dc jacks.
How would people approach this? Tons of pedal PSU schematics floating around but I don't really know what to look for. I have enough stuff lying round in the bitsbox (loads of LM317Ts doing nothing) but it might just be reinventing the wheel.
Any advice appreciated!
