I had to change my plans a bit and I couldn't take care of etching PCBs. Instead I took some time and looked into the 14-segment displays. I was worried at first, but it turns out once you can drive 7-segment displays, 14-segments is pretty much the same, just a few pins more:
That is almost true, except the code and font definition. I'm still working that out, but I guess it's just a matter of time.
The only other news is that I didn't receive yet the FM radio modules I ordered. By itself, it is not big problem, but I still need to make a few design decisions, and having those radio modules and testing them would answer a few questions. There is still a slim chance they will arrive tomorrow morning.
As before, lots of PCBs to etch and now I have some practical knowledge with 14-segment displays. This will allow me to start designing PCBs for them.
Short log entry, but at least there is some progress. I hope to show more next time!
