Break over, testcard generator continues
The lower of the two boards above is the cheap Altera EP2C5144 FPGA board
I bought from China. The board at the top is some perf board with a 3 channel
DAC soldered to it using an SMT adapter. It was not too easy to solder the SMT
part down due to the design of the cheap adapter board. The top board plugs
into the FPGA board. Hopefully I can get the grounds short enough.
I should now be able to wire the whole thing together with Vero prototype wire,
keep the connections short and not need to buy any Vero combs.
I plan to add a sync separator chip to the board so the unit can be used as a text
overlay generator as well as a test card generator.
