In this video I turn the final output circuitry into a PCB. This is circuits from multiple vga videos going all the way back to the first in the vga series. You can probably guess from the length of the video, I ran into some problems with this one. I thought about splitting this into two videos but I couldn’t find a place where it felt right. Conceptually though it has two halves. Firstly the classic schematic, layout, route and solder is the first part, right up until I test the board. Secondly the remainder of the video is troubleshooting, diagnosis and repair. Based on previous comments I imagine some people will be interested in that second half even if they wouldn’t normally have watched a PCB build video.
With the schematic I have a false start trying out a wider form factor, making the PCB’s for the VGA into a (educated) guess of the space I need is proving to be a challenge. We’ll see how that goes when I get to the final couple of modules.
