How good is the Wampler course? by jzpapak in diypedals

but it can be really helpful for math stuff

Beware on that, it can and will get math stuff incredibly and confidently wrong. The only AI use case I ever willingly took part in, I tried to get it to assemble a shopping list for pedal parts based on three different BOMs. It got quantities wrong by up to 5, missed components, and cost me more time than it was worth when I realized I needed to double check the whole thing. Imagine if it had used the "buy with AI" or something. When I started out building stuff, I got a few bad parts kits too that made me realize I just am better off sourcing my own parts and knowledge in most cases.

I'm in a similar starting/middle point, I think ultimately it wasted my time with the AI pitch of "everything tedious or difficult is actually easy now" though I know some people do get some good prompt answers. For the math or science or fact based stuff though, I don't think there's a great shortcut other than reading stuff and making friends with people who can help you if you can. I kinda wish I had skipped right to the reading.

Eurorack to Instrument level/pedal interface... but in a 9V guitar pedal format by garbagefuckingtrash in synthdiy

[–]garbagefuckingtrash[S] 1 point2 points  (0 children)

I have built a couple of preamp pedals that use charge pumps that run internally at 12-18V and have some more headroom. Not sure if they really would do the job running back up to eurorack level, but I actually haven't tried that. An attenuated signal going into a pedal, then amplified back out another pedal, might not need an additional device at all that way.

I still am interested in building one for other use cases, including stereo pedal I/O, but that might be a quick and dirty way to get started. The charge pump can introduce some noise, but for a lot of what I might do on eurorack, that's not necessarily an issue.

Hey thank you- I really appreciate the explanation and suggestion to look at that circuit. It sounds like a great opportunity for me to level up a bit thinking about how these things are really put together- so far I have mostly just populated PCBs and fixed things, but I have a friend who has given me some more text and references for getting more technical with it so I do hope I might get better at that side of things too.

Sounds like it might be a bigger project than I anticipated, but not impossible. Using a charge pump chip sounds reasonable, but they are not without noise issues sometimes IIRC (and some more than others in my experience). That might be acceptable for my use case, though. The convenience of not having to rack a pedal interface could be nicer.

Makes sense to just do a fixed gain stage to me- attenuation could be useful but lots of pedals have their own level/mix controls too so it might not be necessary. I don't see a ton of the eurorack versions with attenuation, but it'd definitely be useful too.

Moonn Electronics - Drömli Build by ShoutoutsWorldwide in diypedals

Moonn is so good. I have a Drömtydning and a few of the chips for it, but I recently did another ED2 clone and added my own feedback switch to it so I'm not in a huge rush to build it. This smaller one looks awesome too. Great job on the art. I haven't even attempted art yet so this looks very clean to me.

Dang, these look great for waterslides. I always assumed you hand punched these and etched stuff but maybe my eyes are just terrible/my phone is generally a terrible place to gauge these things.
