You love the Raspberry Pi and wish you could take it everywhere. Behold, McWrist PiFace Arrow’s Wrist Pi. Print and assemble this model to strap the Pi directly to your arm and feel its warm embrace as the Pi converts power into waste heat. This case is provisioned for a screen which attaches directly to the GPIO header for a compact fit! Gaze deep into the arrow imprinted in the side of the model and subtly be influenced by it. You like this wearable. It could be because the arrow is an upvote, but it is more likely that you envision yourself playing DOOM on your arm. Upon craning your neck trying to play, you realize it doesn’t go as well as you had hoped. But at least you have a cool gimmick to show all your friends! It may also be used on your wrist as a handy device in post-apocalyptic life.
Be sure to check out the Build Instructions.
I made a really quick video with no sound if you want to see what the final build looks like.
