If you’re a regular GitHub user you’ll be familiar with the website’s graphical calendar display of activity as a grid. For some of you it will show a hive of activity, while for others it will be a bit spotty. If you’re proud of your graph though, you’ll want to show it off to the world, and that’s where [HarryHighPants]’ Git Contributions E-Ink Display comes in. It’s a small desktop appliance with a persistent display, that shows the current version of your GitHub graph.
At its heart is an all-in-one board with the display and an ESP32 on the back, with a small Li-Po cell. It’s all put in a smart 3D printed case. The software is the real trick, with a handy web interface from which you can configure your GitHub details.
It’s a simple enough project, but it joins a growing collection which use an ESP32 as a static information display. The chip is capable of more though, as shown by this much more configurable device.
Embedded devs be like “i spent two days writing 20 lines of code. Time to commit this to github”
Majority of the time spent in setting up the hardware setup, setting up the logic analyser or oscilloscope trigger right, setting the hardware peripherals on the MCU correct etc etc
And i wouldnt have it any other way
This can turn from I have something to post, to I have to post something.
haha i want to brag that sometimes i re-factor for a net reduction of hundreds of lines of code, one day after another until it’s thousands
I keep meaning to get one of those e-ink displays. Don’t use github, but I can see they could be quite useful for a lot of other things … for fun.
Sir, step away from the e-ink display.
