I made another, this has that Electric Druid One-Shot chip, so it’s basically the LMNC Bounce without CV-controls or output level control.
The FIRING BOARD name suits quite well for this, so a great success. It even worked at the first* try. And looks quite nice.
*Ok, at the very first I tried how it works without output buffer, with the output filter from datasheet straight to output. Didn’t work well, the output impedance was way too high and unreliable depending on what it was connected to, so I added a TL072 as a buffer. Half of it is unused, but well… With more space I could have put the level control there, but this 0-5 volt output is fine for now.
For those of you (like me) choosing to spray paint your plywood cases I can recommend (in hindsight) using an undercoat on the sides of the ply, because the layers are super visible and suck up paint.
It still needs a bit more sanding and another coat on the edges before I get onto the Neon coat.
Im not sure my eyes are ready for how bright my cases are going to be! Haha.
Some short update on the Kosmo Multitool. Hardware is all working except some small flaws I’ve been able to correct on the fly. Software-wise I got all devices running and started some kind of framework which will ease later development. It is harder than I thought to get decent results from the ADC and DAC. I’m using a calibration factor for the ADC and a look-up table for the DAC which seems okay for now. Currently I’m looking into a plugin mechanism so it is easy to extend the menu and add functionality. Unfortunately I underestimated the amount of memory all the hardware libraries are consuming. I will go for an Arduino Nano Every which has more memory and is pin compatible with the Nano. It should be a drop-in replacement, we’ll see.
Yeah, thanks for the info! I definitely need to look into that. I already threw some stuff out that uses interrupts but now it at least compiles. Everys are ordered, I hope they will show up soon.
My 0.02:
I have a Nano Every, for simple projects(CV in, single channel DAC, a couple of pots and a few switches) it has been a drop in replacement, no issues at all. Having said that, I’m a complete novice at Arduino so haven’t tried anything very advanced.
This is an overload but usefull lo-fi mastering module, specially create for my modular drum rack (Or for other things too). It is composed of a simple two-rate compressor/expander circuits, build with the NE570 compander chip (really good for sound processing effects) by a fantastic Thomas Henry’s book (“Making music with the NE570 Compander”, available in www.lulu.com).Then I added two EQ settings: an old but efficient Baxandall’s tone control and a Tilt EQ (two rate); there are inspired by a design from music thing modular, “simple EQ”.

CowBell, cymbal, iron bar, hammer and sickle and many other metallic sounds. This is a really cool circuit for add to my modular drum rack. I added a cv decay control with a vactrol. I just still put an output passive volume control.
More info here =>
I build a simple adjustable Tom/Conga drum module with an integrated echo’s effect. When we playing with the delay we can make nice beats, and with a cv input we can have so funny and organic sounds like bleep and bloops

Same for you! Thats a nice bit of build progress. =D
Im going to work on testing all the 3D printed stuff ive made so far now that I have made @THOGRE 's buss board, I can test how things all work together.
Ill save up my progress before I post (rather than get told off by the discourse weblords again lol (re:bigbutton necro))
DigiDelay was primarily designed as Guitar effect padal with Sync and Bypass trigger buttons. Some clock2gates on stripboard to push it towards Kosmo Synth. It will also support one-shot echos!
