Thank you. I won't be selling anything, but the files and documentation will be on Github, for anyone interested.
My projects are very easy to build, otherwise I would not be able to build them! Some kit building experience is required. There are no instructions, just a schematic and BOM. That's about it unless you want to dig into the code. I hope that at some point, someone with real C++ experience will go through it and comment. As it is, it works perfectly, and bugs are corrected as they are found. On Wednesday, February 24, 2016 at 7:51:24 PM UTC-5, Greg P wrote: > > Nice clock Mitch.
