Well I ordered an M3 stick for the hell of it, plus a 128GB micro SD card. I ordered one without an OS as I have a spare 64-bit Win 10 pro disk.
@jmtanous -I have a couple of clarifications:
*With connectify - am I correct in assuming that the application tries to join your home wifi network and if it does not find it, creates an adhoc network? Can you set them both with fixed IP addresses? That would make Microsoft Remote Desktop connection much easier.
- In regard to the dongle - it seems a few posts suggest that you don't need one if you are using MRD.
@pfile The power is fed into the M3 stick with a USB cable. I'm also assuming I can find a way of connecting this to a different DC power supply. I don't like the idea of mains out in a damp field. Did you take apart an old charging power supply cable and rig it to a DC to DC converter?
I have a couple of outreach events at local schools and this system will be great. (As long as it does not get stolen 
)
