Powering the Daisy Patch SM "standalone"

Hi,

I’m trying to build a standalone Impulse Response loader/player that can take line level input and supply stereo output. I’ve previously programmed stomp boxes using the Daisy Seed on the PedalPCB Terrarium and Cleveland Audio Hothouse platforms, but this is going in a larger enclosure with some other analogue devices.

I considered using the Daisy Pod as my “platform” but it has things I don’t need (like midi and pots and switches that won’t be accessible inside the enclosure) and I’d need to find a way to wire in separate pots and switches mounted to the enclosure. So instead, I ordered the Patch Submodule.

However, I am confused about how to power it. I see it needs +/-12V and can’t run audio off USB only (as I’d originally planned to do). I don’t have space for a separate PSU inside the enclosure, though I could probably fit a small set of components/PCB.

Ideally I’d run it off an isolated “pedal” power supply that can do 500mA cent-negative 12V, 18V or 9V. However, I am not very experienced with electronics and getting very confused about charge pumps, DC-DC converters, and the like.

I’d be grateful for any help! Or, if this is a dead end, some thoughts on whether I could ‘adapt’ the Daisy Seed Pod to run external switches and pots.

Thanks!

The patch SM is mostly intended for Eurorack synth modules. Eurorack has +12 and -12 supplies (and sometimes +5).

For other applications, the Daisy Seed is more appropriate, and operates with a single voltage of in the range of +5 to +17.

Yeah, I get it. The problem for me is that the Seed obviously doesn’t have audio I/O with buffering and so I’d need a circuit to do that. Which puts me in the land of either making a PCB or adapting something. The Hothouse pedal kit from Cleveland Audio comes close, but is expensive to order unless I try to fabricate my own version.

I did look at the Daisy Seed Pod which does have the audio I/O built in. However I need to wire in my own external hardware – panel mounted stereo output jacks, power (USB?), a pair of LEDs, an output volume control, and a rotary switch for selecting the model. I can’t tell if that is possible on the Pod, where the controls seem to mostly be pre-installed on the development board…

I’d use a Seed.
