Inspired by this neat Nintendo Switch dock, I thought it would be fun to fit an entire game console into a power adapter. The idea is not so far-fetched, nowadays you can get a 4K computer to fit in a tiny box.
This wall adapter features a tiny wireless controller, about the size of the 8bitdo Zero 2. It stores in a small compartment, where it also docks and charges.
After plugging this into the wall, all that is needed is to run an HDMI cable to the TV. Only one cable to deal with! I currently have a Raspberry Pi Zero as my travel kit for gaming, and it needs an HDMI cable, the power adapter, and a wired USB SNES controller to operate. It’s often a tangled, bulky mess.
Speaking of the HDMI cable, I designed the shape of this device to act as a spool for the cable:
With the power prongs folded up, this would make for such a compact kit. I believe it would be small enough to be sold in vending machines at airports and hotels.
For this design I think a bunch of included 8-bit and 16-bit games would complete the package. An SD Card slot for adding games would be welcome too. If you want to be really fancy, this could include wi-fi and streaming apps. A variant with 2 controllers can be done as well.
