Here's what I'm working on now.
My daughter is a Duck Hunt junkie. Given that I'm cannibalizing one of our Super Joy mechanisms, I had the idea that a neat semi-portable would be one crammed into the little light pistol that comes with these units.
I cannot find a screen small enough to actually incorporate this into the project, so this will be akin to the NOAC in a controller posted in one of the other threads.
As you can see, the NOAC board itself, with the cartridge connector removed, fits in one side of the rather empty pistol with room to spare.
I'll be cutting down the other board to provide control logic for P1, which will be incorporated into the pistol itself.
The controls will be on the left side of the pistol. Think of orienting it with the left side facing "up" and in the shape of a "V" or reversed "L" -- hope that makes sense. In this way, you won't have to point the light gun at yourself or anyone else to play the non- light-gun games.
The directional pad will be on the grip , and the buttons will be where there are already some button shaped features. The "start", reset and select will be close by.
I confess that had a temptation to cut the "hammer" off of the pistol, and to utilize it as the extension for the power switch to turn the unit on and off. Cock the hammer to power it up, as it were.
Power will be via either some N cells, though it looks like three AAA (or maybe even AA) batteries will fit easily. Most likely AAA, I think.
I've debated whether to try and wire a 72 pin cart connector. This would run along the right side of the pistol along the flat part of the "slide so it wouldn't interfere with either use of the light pistol, or regular play with no cart.. Several complications, I think. First, nothing can impede the front part of the barrel internally -- anything in front of the LED shaped light receiver. Second, it would need to stick out a bit and would be unsightly and I'm going for as "clean" a design as I can here. Finally, since this is a "TV" connected game, I'm not in any hurry to add cartridge capabilities as I've got a perfectly good YOBO for that!
When it's done, it will be painted using the original FAMICOM color scheme, but with the bright orange barrel thing. Mainly, I want it to look a lot MORE like a toy than it does now.
So here's a pic, just to wet your appetite...
