I’m sure I’m not the only person who got their new Korg Volca thing home only to discover that the power jack doesn’t fit any of the AC adapters you have laying around. This is annoying. I for one have a box with about 30 different power adapters to check through. But I have found a good, cheap solution.
First off, what you need is this:
- DC 9V
- Center Positive
- 1.7mm connector
According to this guy, Matthew Zipkin A Volca device never consums more than 80mA, so pretty much any 9V AC adapter has enough juice to power multiple Volcas.
The problem is the plug is an uncommon size, 1.7mm. If you want to try splicing something together look for the yellow-tipped plugs. If I recall correctly, old Sony CD Walkmans used the 1.7mm plug. But another solution is this: Adafruit sells 2.1mm to 1.7mm DC jack adapters for $2.50. They also sell a 9VDC Center-positive 1000MA supply for 6.95.
The Adafruit solution is actually cheaper than the AC adapters I just bought on Amazon.com, with higher power output.
You can also power multiple Volcas from a single supply with guitar effect daisy chain cable, if you buy enough 2.1mm to 1.7mm adapters.
