Isn'tses Fort Processor - psychogeographic pcb-art noise synth

[WhiteWarlock]

Tim, are you planning on making Eurorack version of your Fort Processor?
basically such will require you making PCB revision... people can make own faceplates...
Give it some Thoth.

We are thinking about it, definitely designed with the possibility in mind..... first thing is to try powering it from 12v, gonna prototype some eurorack-compatible version soon i think :)


Selling the PCBs and a handful of built versions on Etsy too now: https://www.etsy.com/uk/shop/isntses

is it 9v now? will function in frack rack
can you pretty please throw me schematic... here there or whatever
will look around and see if have the chips for breadboarding
then take some notes for coming up with mods for making this 12v module
when have some mythical extra time...
may as well do some R&D upgrading the design
you can have whatever notes/schematics come up with for making this circuit eurorack module pcb
obviously this has potential for becoming way more

hmmm can most likely reverse engineer it from pcb images
will need ordering some of those chips
doubting have have 4040 or 4093 right now
no super stress

Thanks for the interest, In theory it should work with no modification on 12v since all the components are rated for above that, and i put eurorack power header pins on there for experimentation purposes :) should try it today actually. I guess maybe the pitch of the oscs might be totally different?

Sorry we are not giving out the schematic at this point, might be able to in future... , it's nothing too complex tho: basically classic 4040 divider, 4049 amp/distortion, a 4066 switch to toggle/strobe (using one inverter of the 4049 to make opposite high/low switching of 2 signals) between the input distorted signal and the 4093 oscillators, +classic 'twin T' bass drum mangled into more of a drone and triggered by a very low subdivision of the input signal :) all connected together in a probably completely non-optimal way haha

The two build guides contain a lot more info and I'll PM you the mod ideas text i'm writing up and really should finish soon!!

if you are interested could maybe trade a PCB for something?

Thanks the info on Fort Processor & BOM...
sort of just attempting figuring out what exactly the circuit does...
plus getting in some posting time here...
no big stress

Fort Processor kits are back in stock at Thonk after being unavailable for a while due to covid logistics!!! Buy one - https://www.thonk.co.uk/shop/fort-processor/

Also we have bare PBCs - including a new deluxe gold plated version - and fully built circuits for sale on our Isn'tses Etsy and bandcamp pages:

Following on to my reply to whitewarlock above, we have now tested it on 12v and it does indeed seem to work fine and sound the same as on 9v.

We made a podcast/radio show kind of thing featuring noise + music from various Fort-Processor-using artists: https://www.mixcloud.com/lisa-mckendrick-hexa/isntses-podcast-01-fort-processor/

Found a load of leftover PCBs of the original green prototype version, so we are selling a few ready-made green Fort Processors at a discount. They work/sound the same as the black versions but look a bit messier (there are a few extra wires across the board here and there). Actually they should be MORE expensive if anything as they are more limited and more of a pain to build :D so grab a bargain! - https://isntses.bandcamp.com/merch
