Just had a bit of a setback, everyone
Spent over 7 hours working on this today. Couldn't get the right diodes so kludged in some much bigger diodes. Finally got it into a state where I was ready to plug it in and... The Wizzard isn't working. I turn it on, but get no picture or sound. (Maybe the PSU has finally died?)
This is before I even got a chance to plug the controller.
Working on this has highlighted several issues.
- The PCB for the joystick lower is almost perfect. I might move the connectors for the fire buttons here.
- The PCB for the fire buttons isn't long enough. There's interference between the buttons and where the PCB is soldered in.
- The PCB for the joystick upper needs a slight tweak. The solder pad needs moving a few mm closer to the edge
- The PCB for the keypad area needs a LOT of work. Currently there are several issues with it.
Problems with the keypad PCB are:
- I need to add some holes for screws and plastic pins to poke through
- The button spacing is just wrong
- With the diodes on the bottom, even teeny tiny ones, it's going to be too thick
- With the buttons on top, even low profile SMD buttons, there is no way the overlays are going to work. Maybe we move the diodes to the top and just accept we can' use overlays? This would free up some limitations and allow a much cleaner board.
- The connector to go to the next board is both too low AND backwards
Of course the list is completely irrelevant if I can't get the Wizzard working :-/
I need to take a break from this project. I'll take a closer look at everything tomorrow.

You do not have the required permissions to view the files attached to this post.
Keyboard section. The button spacing is off and I need some additional cutouts under there.
Joystick part with the contact section in place.
Joystick part with the contact section flipped over so you can see it.
Initially I'll only solder up some of the buttons, not all of them.
