Alpha Release 3 is done, will take some time to get it but looks promising.


Big thanks to PCBWay for sponsoring this release! I will post a full review and feedback later once I get the whole thing assembled and tested. PCBWay went out of their way to accommodate the really demanding SMT and budget and we had to work really hard to "meet in the middle". That tiny PCB which is the size of a US quarter dollar cost $300, so that's not a small effort.


I know some people ask about time. This type of development takes a lot of time, more-so that I'm working alone, and in my spare time off-work. I have a full-time job. As I mentioned, usually this takes a large team of about 10 to 20 people and about a year to develop (say, 10-man-years, 20-m-y on the upper edge of the envelope) in a high-pressure cooker environment. This isn't a typical home-brew DIY project you complete with off-shelf components and a soldering iron. I'm trying to achieve this at a tiny fraction of the time and budget. Realistically, I'll be lucky if I get the Beta release by March '24.
