It’s been quite some time since I last posted about this. The project has been on the back burner for some time now since I’ve just been so busy with other things. It’s actually pretty far along the process but the cost of the parts is just too high, and the kit has quite a few parts.
I’ve been revisiting the design again to see if I can make it easier to build and less costly.
A question: Would you consider a version without a DAC? Instead of having an 8-bit digital interface (Arduino compatible), it would have analog X and Y inputs and a video/blanking input.
