Ok update, DC 2.1mm Jacks (from China) and 3 pin DIN sockets (UK) arrived already mounted on PCB, just waiting for encoder and also some pre-crimped 2.54mm low profile plugs (for the LEDs) ....as this will same me time crimping my own as this is a real pita task with small gauge wire. If they don't arrive then I'll crimp my own but I dislike this task intensely!
Folks have said they would like to pay for my effort, but I have categorically stated "no" as this is not my design and only comes about from the goodness and willingness of Dave and some left over PCBs from me, so if you feel this way, maybe make a donation to IIS!
Shouldn't be long now, some things from China are real fast other come by camel train!
