I'm retired (yeeted out of the workforce due to Long Covid, and the brain fog)
I'm about to pull the trigger on TinyTapeout, and possibly the Zero to Asic course, so I can get a BitGrid chip running, and characterized. It's either scalable to Petaflops, or not... and I need to know.
This will require learning VLSI design, how to write testing routines, and then there's all of the software required to actually make it useful.
I'm also looking to get a decent 3d printer, and some machine tools so I can make machine shop parts with my own machine shop. ;-)
I especially want to be able to make cutters and hob/shape gears, like I used to for work.
Oh, and continue on with Kicad 8.0 so I can build a PCB for a 16+ channel SDR receiver to do passive radar.
