My first DIY handheld and introduction to BitBuilt - An Intel Celeron x86 PC stick crammed into a handheld form factor!
You may be wondering why I've renamed it to the x86 SNES: it uses a SNES controller for its controls and I'm bad at naming things.
I have started on May 8th and finished my first prototype on June 20th.



Components

On Ebay, I found a pc stick with a 3A draw current. It's perfect for my simple project, since I can use it with a portable phone battery. Most importantly, the PC stick DOES NOT use an Intel Atom processor; those are too weak for simple gaming. The Ebay listing inspired me to build the handheld.

Material list
  • Intel Celeron J4125 (with integrated graphics)
  • SNES controller
  • Arduino nano microcontroller
  • 10,000 mAh 5v 3a portable phone battery
  • 5 inch 800x480 HDMI display
  • HDMI ribbon cable
  • Nintendo Switch joystick (I got the fancy hall effect joy-con joystick)
  • Wires

I spent way too many hours modeling the components, designing the case, and redesigning. Also, I butchered the controller.

Hopefully I remember to continue updating with progress!
