Pi desoldering

A project log for Raspberry Pi with 2.8 inch touch screen

I'm thinking about recreating Adafruit's PiGRRL, except in a different form factor

I'm most of the way to finishing this project, but that last 10% is the hardest part. I followed the excellent tutorial posted by Adafruit on making framebuffer copy work with their 2.8 inch screen. It was very in-depth, explaining why every instruction and command was essential for the process. Here's the link if you want to follow/bookmark it:

I fired up Quake 3 as soon as I was done installing everything:

Today I desoldered all of the excess connectors and jacks from the Pi and soldered the screen close to the board. Here's the mess leftover from the desoldering effort:

It wasn't as clean and easy as Ben Heck made it seem, but it was possible for us mere mortals. Here's the link to Ben Heck's show and the specific episode in which he desoldered the Pi and attached this exact screen:

Ben Heck is frequently my inspiration for projects and what is possible. I tried to take some pics of the screen combo once it was soldered up, but the camera wouldn't focus properly on the thin profile of it:

I still have to cut up the PCB for the controller and wire up the buttons as well as make some kind of 3-D printed case for it.

I forgot that I need a USB port for dragging and dropping ROMs as well as configuring the GPIO buttons, so I'm gonna have to put one back on the board, perhaps permanently. I'm not sure when I'll get to work on it more, but I'll keep updates rolling in.
