Yes… I mean all of my modules are me first ones for now, but the very first, the noise module is the most unprotected. It doesn’t even have the bypass capacitors on TL072 and… At all. But now I actually have a template on EasyEda. It looks like this:

It says 1uf, but sometimes I use 10uf. I am not sure if it affects things at all and If I need them in every module (like in mult, this one is actually from my 2xMult schematic, which is a new module that I’ll show later), but I just like these small caps, they look cute. It is a fairly recent innovation, before that (starting from LFO, the second module) I had this template:

And again, it was everywhere. Sometimes I want to add diodes there, but I am too lazy to mess with my old modules layout. It’s not this simple, sadly. It would be easier to redo it from scratch.
I was considering top do it too. But I don’t know how they call them. And I already kinda spent lots of money on things on Ali, that I should get in few weeks, the most closest package should arrive in two days, maybe three… It has DACs and LEDs and some other stuff for Arduino projects (quantizers and such), so I am actually thinking about DIY way of restricting the power connectors. Like maybe I should glue something on the connectors. The other idea is to clue something on these connectors and make the connectors symmetrical. Like +12 -12 gnd gnd -12 +12. But I like 4 GND wires. And I would have to redo the wiring of my old modules if I want to do that… And I have to redo the PSU connector too… Too much trouble! I need a mechanical solution, I think. Like What they do with Eurorack power connectors. Some kind of notches and all that. I am thinking hard how to do that in my low effort DIY way. I have to do it sooner, cause for now the case for my modular is empty and I have an opportunity to fix my power line and connectors troubles. I had a very sketchy power line, the power distribution thing, btw. It had naked wires on the bottom, so I am redoing it right now too. I also ordered a bunch of striped boards for the power distribution lines in my other case (which again isn’t ready yet. At all, it’s just planks and screws for now). Yeah… I’ll show you later what the problem was with my old power terminals or whatever they call it.
I don’t think it is a bad idea… Maybe people don’t use it because they don’t usually have a problem of connecting modules the wrong way. Well, it also could be some kind of power consumption thing. Like it eats the current. So you just waste it on something that is fairly unlikely when you have proper connectors. Maybe probably.
I hope so too! And It looks like it will be a nice rig. The power distribution would be much more reliable and there would be no weird flux… Or at least not as much as there was before. That remind me that I also need to wash the potentiometers and jack sockets… Argh.
So I’ll write an update on the whole situation later today or maybe tomorrow. Spoiler - washing and reflowing helped a lot
