New 400 in 1 Famicom Project

by Onyxthecat Fri Jan 09, 2015 10:32 pm

So I wanted make some custom lables and get a neat set of real Famicom carts for a little side project to sell on my etsy store. After I got them done I realized the new board was way different and wasn't going to fit inside easily. So now I'm not sure how to proceed. Maybe make custom mounts and epoxy/J.B Weld them on to hold the board? What do you guys think?

No response?
JB weld is stronger than aluminum. I know this because my brother used some to fill in parts of an aluminum engine block that wasn't supposed to have the header he put on it, then he machined it and ran it as his engine for a long time. When we disassembled the engine it hadn't changed at all. It's cheap and more permanent that most materials.
Hot glue or 2 part epoxy would also work for this type of application.


I like the logo - I'll buy one.

I use JB Weld too, stuff is strong. I once filled in a cracked hollow gear shift knob, put it together while the epoxy was still wet. It solidified to make the knob very solid, no more cracking of the handle while shifting gears.

I wonder if there are a bit of metal in the compound that might make it conductive. That could be an issue for the PCB mount. Is that cart really 400 individual games?

Yeah, there is iron powder in JB Weld, tho it's surrounded by 2 part epoxy. I've tried to pass a current through cured stuff and had no continuity. Still, 2 part epoxy should cure harder than a famicom shell anyway, and it's cheaper.

You got my interest depending on the 400 games in 1 you'll shove on there. Do advertise that on here when the time comes as etsy is a hot mess trying to find anything.

Alright, thanks for the responses. I found a plastic welding epoxy with 3500 psi tensile strength. I have the cart together now with plastic supports inside since last night. Should be fully cured in a few more hours.

BTW, here is the board I'm using:
