Project 01a
I decided to mill the asynchronous circuit. And I'm not great with electronics, I still have some issues understanding the essential structure of these various circuits. Milling in progress. There was initilally a problem with the endmill that none of the traces came out properly when I tried. Dan then suggested zeroing the endmill at various places and not just once at the corner of the board. This actually worked and the next four boards that I milled came out perfectly.
Project 01b
I was able to successfully program the bridge and one node with Dan's guidance. The other node however was giving me some problems. Dan dint know what was wrong with it either. After grappling with the issue for a while, I decided to mill and solder another node instead of wastimg time debugging it. Unfirtunately the otehr node dint seem to be working as well. This should esssentially be a work in progress until I figure out whats wrong with the nodes.
