This is the status:
Owing to the strong interest, I will go ahead with the PCB's. I've sent the Gerber's to the PCB plant, they will let me have 2 protos as soon as they are done. This could be up to 5 working days, they say they are busy.
Once I get them back, I'll build a pre just to make sure all is OK, & once done, we'll get all the boards out. Looks like 80 PCB's at the moment.
I will have a Paypal account set up in the near future for this project.
