Hah, don't worry - I didn't think it was harsh. I've had no training/edu in HDL whatsoever, so this was a deep dive - I expected to be told I'm doing wrong!

The end result is on FPGA, yes. Still a long way before that works. And I'll make sure any massive screwups are documented in next parts, those are the best parts (and, probably most valuable) to write about :)
