Poor in what way? It’s a PCB for a 100 VA toroidal transformer connected to 115/230 V mains. I guess you could leave out the warnings, but that won’t make the dangers go away.

more power ! that makes a whole bunch now , why do the lights in the house dim when I turn my modular on LOL

They are, so I guess they’re not exactly the same.
Poor may be a bad choice of words @fredrik. It’s one thing to design your own board and through ignorance proceed to burn your house down or blind yourself. But I always feel “iffy” when “it worked for me but may kill stupid folk” hits the hobby market . Like these folks who print plans for 3d guns etc. I just believe you should stand by your work and be prepared to support it.
Not picking a fight with you or metatronics but this is like a kit plane, one cock up and it’s toast. To me that’s not a product it’s a dare.

Exactly @Bitnik ! Kits like this are unfinished professional work and are “unnecessary“ in a DIY world.
Apologies too to @ChristianBloch. Sorry, didn’t mean to poop your purchase mate. Products like that just scare the crap out of me. Play safe.

in reading on these boards [ frequency central FC power ] which I should have done first . the 7812 / 7912 regulators are only rated to 500 ma draw or about 7 / 8 ish modules that pull 60 ma . the 2 amp wallwarts I am using are overkill to . I do have some .47 amp wallwarts wonder if those would be adequate ?
Remember the wall wart needs to supply the total current, if it’s 400 mA on +12 and 300 mA on -12 that’s 700 mA.
Where’s this 500 mA from? ST L7812 is rated to 1.5 A, with adequate heat sink.

muff wiggler forum really old posts probably rev. 1 boards . yeah I was planning on using the 2 amp wallwart anyway just because more head room . I have 16 modules in each rack box and plan on using two of these power supplies per box .in theory that should be fine . I will double check the exact specs of the regulators I am using [ lm7812 and 7912ct ] . thanks for the heads up on the numbers . if we go on about this it will have to be transported to the diy power supply thread

No worries. I personally appreciate the warning, though I didn’t need it. I do find it hilarious.
All in, this build is costing me around $100 whereas a finished build would have been $250. And I’m building two. So far. If I didn’t feel confident I could do it and do it safely, I shouldn’t be saving that money.

They ain’t much, but they’re mine! Barton Circuits Sallen-Key VCF and Analog Drum PCBs. I didn’t realize how fiddly this was going to be…

I’ll be building one of those filters soon! Putting it behind a Kosmo size panel and moving the middle board mounted pot to the bottom, panel mounted, for larger spacing. And I’ve built the analog drum, too, in Eurorack format.

Just a tiny little order from JLCPCB
The Mikrokosmos are up on Tindie. The rest are intended mainly for my use but I’ll sell off leftovers once I’ve checked them out.
