yep! they were intended for tour only, but due to no tours going on! I have another load coming, they are inverted though. doing a limited run of black on white. pithing the next 7 days! ---

I thought I should add this! its a response to an email I got yesterday Can i power the fart box with my eurorack power supply? YES You can just skip a few components on the fart box as it has a built in power filter No need to solder in :- D9 D10 D11 D12 D13 D14 U8 U9 C17 C18 The above are the components you won’t need if your powering it from the Eurorack. You can still put them in, it will work either way Solder the eurorack +12v to the positive leg of C4 Solder the eurorack -12v to the negative leg of C5 Solder GND to the negative leg of C4 That will make it powered by the eurorack power ---

> [@fredrik](#): > > It’s a mockup, and I need to figure out where to put the switches, also I cannot count so one of the pots is missing from the cross contamination synthesis panel so need to redo that one. And maybe I should get some brown filament? its awesome fredrik! looking forward to seeing it buzzzz… or should I say fart ---

On the flip side of this, what would be the best way to power a couple additional modules from the fart box power supply? ---

The reverse — get the voltages from C4 and C5, where you’d inject them if you didn’t use the supply. ---

Hey all, almost got my fart box good to go! Question, what do the trim pots do? Thanks! ---

The upper ones are 3340 scale trimmers (check the various 3340 threads for how to best trim them), the others shift the triangle output up and down, iirc. Not entirely sure what to aim for with those, but odds are @lookmumnocomputer has some suggestions. ---

Thanks! Got mine mostly working, but I was using spare salvaged caps from other electronics and parts might be bad, so ordered some new things. My cutoff/resonance doesn’t seem to be working as I imagine it should be. The BOM had switches as “on-off-on”, but I’m now wondering if they should be off-on? Anyone know? ---

Pretty sure that’s an error. Haven’t switched mine yet, but I will eventually. ---

I dont suppose anyone has a copy of the fart box bill of materials??? its disappeared and I can not seem to find it! if not thats ok ill make a new one, but I thought id first ask! thanks ---

Huh, I was looking at that not that long ago, and then somewhat asked what a BOM was [so I linked to it](https://lookmumnocomputer.discourse.group/t/suggestions-for-part-suppliers-in-germany/1059/8) but didn’t save a copy, because, you know, “the cloud” and all that. Have you double-checked if it ended up in [drive.google.com/drive/trash](http://drive.google.com/drive/trash) by mistake? (I was about to suggest searching your drive for “1DJFKooefsL-sErRvynaODwfEZe6ILGkZ” but seems you cannot search for document codes…) ---

Oh, I wondered why you posted about the BOM in the german supplier thread, but that’s where I mentioned it. Which I discovered after moving the posts here. Oh well 😃 ---

I kinda like the juxtaposition here of FaceBook and FartBox. [Previous page](https://lookmumnocomputer.discourse.group/t/fart-box-builds/828.md?page=1) [Next page](https://lookmumnocomputer.discourse.group/t/fart-box-builds/828.md?page=3)
