Ben makes a Yobo portable that accepts NES cartridges. Yobo is a brand of Nintendo clones. They are essentially Nintendos on a chip, glop tops on a circuit board, and it is basically a clone of Nintendo systems. The goal is to make a Yobo portable that is about the size of an NES cartridge. Visit the Ben Heck Page:

Yobo is a brand of Nintendo clones. They are essentially Nintendos on a chip, glop tops on a circuit board, and it is basically a clone of Nintendo systems. Ben found one of these in a junk pile for $5 and as it turns out it works. He was thinking they could hack it up and use the parts to try to make a really small Nintendo clone. He wants to make it so it’s about the size of an NES cartridge. It will be more than an emulator, it will accept NES cartridges.

Ben starts on the case design using Fusion 360. He’s got the PCB mostly done. Ben noticed an issue when they do their laser paint. It’s hard to get the copper out from between traces so he went into design rule check. This is a file that indicates what tolerances the board house will accept. You can check your design against it. Once that’s taken care of the PCB is mostly done. He’ll still need to add a capacitor for the audio amplifier though. He’s using through –hole on some these parts to use up parts on hand (audio amp and controller shift register). Ben continues to fine-tune the design in Illustrator.

The final design will use the same type of flat Li-po batter as the Raspberry Pi No HDMI project. Ben laser prints the front panel. He 3d prints parts with Makergear M2 and the old Replicator 1. Felix works on the PCB while Ben works on the screen. Ben always laser paints at the laser’s top resolution of 1200 DPI, even though it’s pretty slow. Meanwhile, Felix uses a scrubbing technique with the PCB to make the copper dissolve faster. Ben uses a digital potentiometer with pushbuttons for the volume control as there’s no room for a physical knob or dial.

At 15.50 are you cutting holes in the FR4 with a laser? My laser wont touch that at all.

Ben clean a cart with some wd40 and stick it in the portable. It will loosen up that yobo 72pin adaptor. Those are notoriously tight.

Wow, that looks wonderful, guys! Probably one of the best NES handhelds I’ve seen. Great touch exposing the label and also keeping the carts mostly receded into the device! All hail the little handle grip.

Pretty sure Contra was before Predator, that artwork is a Commando ripoff I believe.
