OK folks, here's the deal. I have about 20 boards left of this project, and am willing to let them go for $50 USD each plut PP and shipping. There is a problem, though with the mini toggle switches. Mouser used to carry them, but they seem to be presently out of stock with no plans to re-stock. There is another source, but there is a minimum order of 100 pieces with a 6 week lead time. I would suggest some sort of group buy, but since each board uses 4 switches, that would mean 25 boards, and I have only 20. All of the other parts are pretty much off-the-shelf. The other issue is that I have some family medical matters that are taking most all of my time, so the support for this project would be VERY limited. I might add that this is NOT a project for beginners, and while I have an up-to-date and correct BOM, it is a pretty tight board.
