Issue 3 PCBs are identical to issue 2 but have less Oakley Buss headers available. I've restricted it to eight 0.1" three way headers now. Issue 2's thirteen was somewhat excessive for a distribution board containing 16 power headers.

Shouldn't it be pins 1 and 3 and pin 2 not used?The midiDAC, however, generates the CV and gate lines for your modular so this should have two wires connected on its buss connector. Both pins 1 and 2 are used on this module.
Also I have a bit of a hard time to understand under wich circumstances I should connect the optional links R1, R2 and R3 (I see that you ommited them on Dizzy 4). My system is mostly built of Oakley modules plus a few other brands (Haible, MOTM, Yusynth, CGS, Barton,...). By now I have built everything with dotcom style connectors and used diy MOTM adapters where needed. Also I have some Dizzy 3 and some Dizzy 4 boards in the drawer to use.The middle location, pin 2, is ground on the module and this should not be connected to the Dizzy or midiDAC modules. Connecting the two grounds in this way could induce earth loops and introduce hum or crosstalk in your system.
Yes. I'll get that corrected. Thanks for pointing it out.Shouldn't it be pins 1 and 3 and pin 2 not used?
In a standard set up you would only connect R3. You can ignore R1 and R2. R3 simply connects the middle pin of the Oakley Bus header to 0V and is used to electrically isolate the noisy gate signal with the more delicate CV line. If you are not using the Oakley Bus then you can omit R3 too.I have a bit of a hard time to understand under which circumstances I should connect the optional links R1, R2 and R3
I use Molex KK 0.156" connectors rather than MOTM's MTA156 system. You don't need an expensive tool, just an ordinary Molex style crimper, the housings are cheaper, and I think it's a better connector too.Leverkusen wrote: ↑Mon Mar 09, 2020 9:45 amnot really looking forward to crimp those 60 wires for the MOTM connectors by hand...
