Ah, ok thanks. So you’re using a barrel connector coming from the D-tap? What are you using as a power supply in your Eurorack? I could see no power supply unit that takes the power from the battery per se. Do you have some kind of regulator? My uzeus takes up to 15v but my lithium NP-1’s charge to over 16V when full even though they have a lower nominal voltage and I’d be concerned about plugging them in directly. For my audio bag I wired a cheap DC-DC voltage regulator in line with my barrel connector for audio recorders with narrower acceptable voltage ranges to ensure I wasn’t going over voltage…
…scratch the bit about what power source, I just spotted your uZeus in plain sight! Still interested to hear if you have a regulator on the D-tap.
I hid the power supply so well you missed it!! There’s a 12v 1amp regulator on it in this pic as that’s what the Digitakt needs. I’m not an E.E. so take this with a granular of synthesis but I don’t use a regulator with the mico zeus as it’s specs and the battery match. There’s no overheating that I can tell and all 4 modules function normally.
I wired mine by hand from cobbled together eBay components (and Brian’s seen evidence of my soldering skills!) as I was powering a Tascam DR680 and didn’t trust the “Y’should be right’s” I was hearing in response to voltage ranges. I had a digital voltage display so that i could keep an eye on that, so transited many a Colombian and Mexican airport security with a device which looked for all the world like a bomb counter in a 80’s TV show replete with green AND yellow wires!
It’s still floating about somewhere, perhaps I can repurpose it!
He he…would it surprise you to know the wiring was speaker wire twisted together and taped with electrical tape? I swear I’ve been busily up-skilling since the…ahem…flimsy diode pad issue
