Wolf + Lamb Custom 3 Channel Midi Controller

Step 5Add the Battery Pack Hack

Add the Battery Pack Hack
Before I finished the controller, I added a 9v battery to power the whole thing. After unscrewing the case 2 times to replace it, I went to Radio Shack and found a model airplane battery pack w/ recharger.

Using two sided tape, I affixed the pack to the inside of the controller, connect the power leads through the power rocker switch, and into the Doepfer board. I left the recharging harness hanging out of the back through the power supply hole I had made for the original power input (on the board itself).

We now recharge it for a few hours, and travel for 2 or 3 performances without recharging since the Doepfer uses very little current.
