Raspberry Jam 2023

with the Hackberry Men’s Shed

Software

Linux OS (Raspbian in my case)
The pi-clock package I forked at my GitHub page

Hardware

Display

I used a N140BGE-LA2 LB3 1366X768 LCD panel that I ripped out of an old laptop. I got the controller board by searching for that exact model string on eBay and purchasing the results; it takes 12V at 3A to run the panel. I cut a display area out of a piece of project board from Home Depot with a jigsaw, then used a router with a rabbet bit to make the inside edge wider than the outside edge. Another piece of project board screwed in behind it holds the panel in place (though I did have to do some work with a utility knife and a chisel to get some fiddly bits cut out properly).

Power Supply

I used a simple 12V power supply sourced off Amazon. Though it included a USB port, I didn’t want to rely on that and got a 12V-5V converter with a MicroUSB output.

Raspberry Pi

I used a spare 2B, as this project doesn’t really require a lot of computing power. In fact, there’s enough spare processing cycles on the Pi that it would be easy to trivial to run a basic web server for a site very like this one, along with my Home DNS Forwarder.
