Nice, my order is in!
Wonderful, I’ve got one!
-Fumu / Esopus
No one had buy some in Europe ?
I’m preparing an order to jlcpcb for this week.
Black Frontpanel + Red PCB (both in 1.6mm, too expensive to get frontpanels in 2.0mm)
Here’s what will be left for sale:
- 2x AO’s Busboard (12x(2x5) version)
- 3x AO’s Quantizer set
- 0x AO’s MikroKosmos set (I’ll keep all 5 for myself for experimentation with various springy things, so if you want some I’ll have to order more than 5)
- 0x AO’s Protoboard (in white, not red) (just as above, I’ll keep all 5 for myself, but can order more)
- 3x Maybe AO’s GateGrinder set (I’ll get them eventually, but maybe not yet) (3 left)
If there is enough interest for them, I can add any of the other public designs (in Kosmo format) from Analog Output, CTorp and d42kn355/cruxFX (and maybe others I don’t know of ?) to my order. I’ll get them anyway, a few every month to not blow up my budget… And keep 2 of each for myself, so 3 of each left for sale.
I’ll sell the leftovers at cost + 2 Euros per order for packaging + shipping from France (if you don’t live in the EU you better order direct from JLCPCB…).
Many thanks to the authors for sharing their great work !
cool thank you very much, I would be interested in only the PCB of the Quantizer if it is possible, if not with the panel but I would not use it as much as it serves someone 
As the Quantizer PCB is “generic” (dac/ino), I can get 5 more for experimenting and sell one to you.
@analogoutput Can the Ginkosynthese Grains firmwares be adapted to dac/ino, or is the hardware way too different and would need a complete rewrite ?
I know the grains uses PWM and dac/ino has a “real” DAC, but that shouldn’t make a massive difference in the code… unless writing to the SPI DAC is to slow (vs the PWM register write) to keep up with the sample rate.
yes I would like that, thank you
keep us informed
Not very familiar with Grains but… I mean, it’s an Arduino Nano, it’ll run the code, input pin assignments might have to be changed but that’s trivial. Question is the analog output. Synapse, the project dac/ino is based upon, was designed for control voltage output, not audio, and I have no idea if the DAC outputs are fast enough for what Grains is trying to do. Maybe you could use PWM — Grains writes PWM to pin 11 which is used in dac/ino to communicate with the DAC but if that can be changed to pin 6 or 9 those are available (one’s buffered and connected to a 2-pin Molex for an output jack, the other connects directly to a header or 8-pin Molex). Looks like Grains uses a hacky alternative to analogWrite and my guess is it can be made to work on pin 6 or 9 but I’m not sure. On Grains the PWM output is connected to a low pass filter, so doing it this way you’d probably want to bodge a resistor-capacitor network onto the output. Or not, the filter can be bypassed on Grains: “Bypassing the filter provides more clarity and a slightly louder output but more artifacts in the sound.”
Well, try it and report back!
Added: @sebastian was messing with a module that could run Grains sketches, apparently it worked but there were tuning issues. Probably a solvable problem. The hardware can be considerably simpler than dac/ino if it’s just running Grains.
Thanks for the info.
I’ll have a look once I get the PCBs.
The tuning issues were probably because of a broken Arduino! I will try with another one soon…
Does anyone in the Eu desire panel blanks?
I planned to release all the panel blank gerbers.
Figure now would be a good time lol
Let me know if you want the gerbers @eric
Blanks are evil
You always need some to fill the holes in you case, just to replace them with modules a week later !
But yes, a few blanks, of different width, are always useful.
They’ll have to wait a couple of month to be manufactured until my budget will allow it.
I was thinking about a 10cm blank having 8 screw holes top and bottom, spaced as if it was 4x 25mm panels, to ease the drilling of the holes in the wooden rails. Hope this was clear
Blanks are great for DIY modules, not just for covering gaps! I realized after too long that I can buy Eurorack blank panels for about the same as all the other methods I’d tried for creating my own.
I have never tried to drill such big holes if FR4.
Maybe it works great, maybe not at all. It’s worth a try.
In any case, a really sharp drill is required for fiberglass based materials.
many have used my panels for DIY as well
I think I made drill dots on the 10 and 5cm’s lol I can’t remember which
One of d42kn355’s blank was accidentally out of stock and out of inconvenience I was gifted a dupe of the panel that looks like lookmumnocomputer’s pin set. They’re applicable when I ever decide to display both side. The open purpose of blanks spurs imagination. The first idea I had was getting blinking lights where the speed was CV and the pattern was generic to the blank’s internal components with lights blinking at different times.
-Fumu / Esopus
I’m definitely looking forward to more of the 10cm blanks. The dot pattern is rad.
I drilled a switch-sized hole in my Splashback Delay panel and enlarged a couple of stupidly too small holes in one of my own panels using a Harbor Freight step drill and drill press and it presented no problems.
