Bam, I have a sealed DS18B20 sensor for you.
I was going to make them up to the 3pin DIN but if you want I can just send so you it to wire thru the motor DB9 and place as you wish. Or I can just give you a std non insulated DS18B20.
I have your PCBs all but made, just waiting for the gray encoder, DIN PCB sockets and few other small things.
I spoke you you about DC jack, aka you requested 2.1mm but I have not yet put that on so you can change your mind still!
Powering all devices is a real pain, I made a small distribution DC/USB hub so I can power multiple devices (and DSLR with +8V) and have a 4 port USB hub all in one. Things like this are invaluable to users and many users make their own.
