We’ve seen our share of do-it-yourself portable game systems in our time, such as this handheld Nintendo 64, or an NES built into an NES game cartridge. This time around, the portable NES isn’t built into the vehicle through which you play it, but is instead impressive another way: it’s 3D-printed.Dubbed the NESPo for obvious reasons, modder Dave Nunez decided to create the portable NES using a Nintendo-on-a-chip (NOAC), which is an NES hardware clone, because he didn’t want to destroy an original console. He purchased an NOAC for $15 — the Retro-BIT RES — and chopped it up to access the vital guttyworks. A $20 4.3-inch TFT reverse camera screen was used, as well as a NiMH rechargeable battery in place of a lithium polymer battery since those require a specialized discharge circuit. The battery bestows the overall system with around three hours of life.The unique aspect of the NESPo, though, is that the case and buttons are 3D-printed. Nunez designed the parts in OpenSCAD, then printed them out with polylactic acid (PLA) using the Makerbot Replicator 2. The entire printing process took 14-and-a-half hours. After that, Nunez affixed all of the NOAC parts into the casing.Then he designed and printed the buttons, attached them and the case’s front and back face plates, and hoped nothing broke when he smooshed the whole thing together. The end result is a nice, do-it-yourself portable NES that houses the game cartridge inside the unit. It may not be ergonomically sound, but it looks nice and is playable.Check out Nunez’s blog for intricate details of the entire process.
