Thanks for the thought stream Erich. I have one other wacky idea for the list. Maybe for next year when life in theory will settle or possibly over the 2020-2021 winter.
I’d like to re-engineer a device called the CNC FROG. It was originally a kind of 1.5 or 2.5 axis CNC gizmo but really it was just a flexible stepper motor controller and driver built into a single quite ingenious UI. I think it sold for around $USD 150 with some bits of hardware for Sherline and Taig lathes. You could do ordinary turning and threading with it. As it turned out though what it was really good at was just driving random bits of machinery via stepper motor. The UI (a generous term) was very clever and flexible so you could configure it to operate in any units you liked after a short setup period. So you could advance a machine in thousands of an inch of hundredths of a millimeter or fractions of degrees or radians or anything else you could cook up. This flexibility had it selling into light industry for operating turntables, indexers, etc. There were and are lots of solutions for the very computer literate but this was for the illiterate. The flavour of the FROG reminds me of forth somewhat. Small, fast, flexible and a bit obscure. A niche in other words. The project would need a new hardware platform - probably an open source hobby platform with PCB’s and assembled gizmos with options and cases which would be fun but the key functionality would be the firmware. Developing a small, simple, elegant UI I suspect would be very controversial and difficult. There is something of a template in the original but much could be done to introduce more elegance. I’d try to fund the project so it would be a paying proposition for major participants. If you are interested in the FROG CNC it is hard to find now. This might get you started. http://www.cartertools.com/frog.html > On Jun 28, 2020, at 10:29 AM, Erich Wälde <ew.fo...@nassur.net> wrote: > > - Whacky Ideas > > - git? -- With all the cool kids using git repositories, should > I attempt do convert the existing repositories, webpage, etc? > does sourceforge.net <http://sourceforge.net/> provide git repositories? > Can the > existing svn repository be converted on the server side? > sourceforge is OK but github seems easier to use to me.

I’m somewhat surprised that it is in suspended animation given the popularity of Arduino as a platform. I find virtualization a big complicated hammer to solve problems that could be resolved in a more elegant manner. Simplification isn’t very popular today though.
