I spent my weekend putting these kits behind a Kosmo panel. The first 2 kits, a Boss FA-1 and a OD-1 clone, are done and sounding great. I’m still waiting on a few parts to make the HM-2 clone work.
These Aion kits all called for opamps I don’t keep on hand to be close to the “originals”. (LM1458, LM348N, 2N5088)… I’ve just been tossing in TL072’s. Sounds just fine to me.
I left the other components as is in the kits, so my guitar playin buddy can just plug in when he comes over. I’ve been using a passive attenuator before an a Barton BMC30 after for my Kosmo stuff.
I love how Colin just melts into his synth and the music! He also has his very own style, not the typical atmospheric or synthwave-like doodling, simply different and refreshing.
so I am working on a cheaper alternative to aluminum rack rail this looks promising so far the only problem I am running into is modules that the component pcb’s are less than 10 mm from center of mounting holes
8mm is as close as I can be before I have to start " modifying " holes on face panels and filing the edges of pcb’s to try and gain a little more clearance .
These look amazing!!! I’m a big fan of oval mounting holes and I put them on all of my panels. I do it more just in case I screw up my math when placing them in kiCad. I inherited a router recently from a friends father but I still need to learn how to use it.
I’m going on the road again so I have to step back from building for a while, but wanted to post what I’ve got so far. 12 modules done, a few just need a little tweak here or there, but it’s nearly a full box!
Today I finished the pesky MS-20 filter, turns out that the 13700 wasn’t pushed into its socket, there were a couple of dud resistors, and the output jack wasn’t wired into the resonance pot, etc etc.
I also soldered up one of my noise generator boards which worked first try.
Demo with noise generator filtered with the MS-20 stripboard:
it’s actually a fume extractor with, as you presumed correctly, some homegrown lighting in it
