Dave,
This is a copy of the standard response I sent to those who prepaid:
"Received the Paypal, thank you. The casings and other machined bits are enroute and the boards are about a week and a half away (Wayne's creations are being microscopically soldered together as I write this) from completion, after which I get them and begin my slave labor. Will update at CPF if something goes terribly wrong but I doubt it, in fact things should be even smoother this time around since I have the experience of forty nano-robot soldering operations behind me from the first run, and have grown little magnifying glass lenses in the fronts of my eyeballs..."
So there you have it. As long as the parts all get here, I begin. To maintain the best results I can, they are built in little bunches, maybe four to six at a time, after which I wait for things to cure and set, then I test, then I ship. So depending upon where in the prepaid queue you are, it may be a slight while. But of course, "All good things come to he who waits..."
