I made my own TRMNL e-ink device
I made my own TRMNL e-ink device launched on April 24, 2025 with 85 votes, #535 of 7,818 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
The creator built a custom TRMNL e-ink device, a wireless display that shows information on an electronic paper screen. Designed for personal use and hobbyists interested in hardware projects, it demonstrates how to construct and customize this type of device. The project is documented on the creator's website for others interested in making their own e-ink displays.

From the sources
Some time ago, my friend George linked me to TRMNL , a new battery-powered e-ink display with an associated service that generates the images that the display will actually show. It looks really well-made, and I have an irrational attraction to e-ink displays, so naturally I had to pre-order one. Their website is a bit confusing, and doesn’t entirely tell you what the things you’re buying are, which made the purchasing experience somewhat more painful than it needed to be. For example, along with the device, they sell a $20 “developer edition” license which “unlocks their API”. I expected this upgrade to give me API access so I could retrieve the image…from stavros.io

Trading cards made with e-ink displays2022 · wyldcard.io · ▲1,149I made a thing! In 2014, I was holding a stack of iPhones and thought to myself: "Hey, if I had each phone display a playing card, I could click a button and they'd shuffle themselves" I pared that idea all the way down to this: trading cards made of e-ink displays. Right now, each card costs me about $20 each, but with only a bit more scale, I think I can get that down to $10. In doing this project, I learned how to design electronics and circuit boards. I learned Rust and wrote my first driver, I upped my CAD skills, 3D printed, and did my first resin casting. I generated the images on the…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
