Just went through a small set of minor upgrades and fixes. Had to fix the plunger sensor assembly, an accidentally snipped led data wire (oops) and the power switch connections. Upgraded the cab with a tactile rotary volume control provided by OakMicros (thank you Mike!). Volume up and down is controlled by input button presses with the zebs I/o board. Works awesome with PinVol. Button press is configured as coin in. See pictures
