Pedalboard

Design and 3D models to make my pedalboard.

The current design hosts 5 pedals with filtered supplies using ZGP modules and a built-in battery. There is an unfiltered DC extension on either side. The extensions are unfiltered to preserve battery life, since the filters account for most of the power consumption.

Fact-finding results

I did some experiments to validate if the concept of ZGP filters with the myVolts USB adapter would work.

• myvolts connected to 7 ZGPs first (no pedals), then connect myvolts to battery
  • doesn't work (ZGPs flicker on and turn off immediately), probably due to inrush protection in the myvolts
  • plugging USB in and out repeatedly doesn't work
• myvolts connected to battery first, then connect myvolts to daisy chain with 7 ZGPs (no pedals)
  • doesn't work at first (ZGPs flicker on and turn off immediately), probably due to inrush protection in the myvolts
  • plugging DC jack in and out then works (ZGP caps are charged -> able to power on)

• myvolts connected to battery first, then connect myvolts to daisy chain with 7 ZGPs and 5 pedals

  • doesn't work at first (ZGPs flicker on and turn off immediately), probably due to inrush protection in the myvolts
  • plugging DC jack in and out then works (ZGP caps are charged -> able to power on)

• myvolts connected to battery, no load

  • after 15 minutes, battery powers off
  • connecting pedals does not wake it up
  • pressing battery power button does not wake it up
  • only way is to unplug/replug myvolts
