I spent a few days soldering parts together trying to rearrange the schematic in my head to make building easy.
I made plenty of nonworking flip-flops, so I went back to basics.
1) Install KiCad
2) Enter the schematic of one flip flop
3) do a PCB layout pretending I don't have a PCB so i can get all the parts in the right order and connected together properly.
4) Start soldering!
I'm on step #3 and I'll post the KiCad files soon.
