Did you learn circuit design by yourself or are you working in that industry?
Thanks man, simplicity was the main goal.

I have just been teaching myself really. I have a basic grasp of electronics, and a plan of attack, and built it up from there really

so i was having a little play with my super accurate power meter

Image

the highest i could get it to go, was while just being sat in the retropie menu. a quick sonic speed trial actually dropped it to 0.15-0.17ma so we could easily cope with a tiny drone battery :) maybe 400mah to get 2 hours

as a sideline, i have already been playing with some other ideas to go even smaller still!!! pushing the boundaries a little with this screen!!

Image

maybe 96x64 is no good for gaming!

No but 128x128 is workable... Especially with pico-8 running natively at that res :)

How did you set the iled screen up by the way?

i used the good old fbtft. need to play with the speed, you get flickery 'brighter' lines

Code: Select all

sudo modprobe fbtft_device custom name=fb_ssd1331  gpios=reset:25,dc:24 speed=16000000
Just running it on a pi3 as a quick test of the Chinese wares

Image

but can you spot the deliberate mistake?

hmm seems my image didnt upload properly!! I can still see it, but maybe nobody else can

yeah the image is reversed. apparently its down to the initialization command on the screen. Sure adds another layer of difficulty to playing games

I have fixed the switch issue, so you would be able to turn it off without the protection kicking in.

Rounded the corners, put holes in all the corners, made it look a bit better.

I wont be ordering any of these, will be hanging on until i add safe shutdown and the like, but if anyone wants to play, feel free
