Products that do what From Hacking a T480 to the Fastest Open-Hardware 75 Hz E-Ink Display does
Three years ago, I posted here about hacking together a fast e-ink laptop from a T480 because I was tired of spending all day on LCDs. I liked e-ink’s comfort, but it was too slow for day-to-day use. https://news.ycombinator.com/item?id=26245563 That post drew in people, which grew into a community experimenting with ways to make e-ink usable for everyday computing. That project later turned into a company and a multi-year project to make e-ink fast and open. We built our own FPGA-based controller, Caster, and went through multiple iterations to push past e-ink’s usual limits,…

Hello! I'm Byran. I spent the past ~6 months engineering a laptop from scratch. It's fully open-source on GH at: https://github.com/Hello9999901/laptop

Finally got my hobby OS up and running on real hardware. I love the old IBM thinkpads, so thought it was the perfect machine to get it working on. Been working on it for quite some time now, but this has been a big milestone!

A while ago I was looking for information on a obscure and short lived British computer. I found an article[1] in the archives of BYTE magazine[2] - and was captivated immediately by the tech adverts of bygone eras. This led to a long side project to be able to see all 100k pages of BYTE in a single searchable place. [1]: https://byte.tsundoku.io/#198502-381 [2]: https://news.ycombinator.com/item?id=17683184

Today, we’re launching our first product on Crowd Supply: a fast, open-hardware dev kit for driving e-ink displays. It supports 75Hz refresh, both color and monochrome panels, and more. This all started with a post on Hacker News about building an e-ink laptop. That post led to conversations with makers, minimalists, and others exploring how e-ink could fit into daily life, or help with personal health challenges. From those conversations came a community, which grew into a project, became a company, and brought us to today’s launch. We bootstrapped from the beginning, pushing through COVID…

3D printing is such a fascinating field of technology, so a couple months ago, I decided to take a deep dive and learn how they actually work! This took me to one of my very first PCB projects, a small, cheap, 3D printer motherboard. While it's not the most cutting edge board, I learned a lot and I fully documented my process designing it (https://github.com/KaiPereira/Cheetah-MX4-Mini/blob/master/J...), so other people can learn from my mistakes! It runs off of an STM32H743 MCU, has 4 TMC stepsticks with UART/SPI configurations,…

We wanted to do something very challenging to prove to ourselves that we can do anything we put our mind to. The reasoning for why we chose to build a toy TPU specifically is fairly simple: - Building a chip for ML workloads seemed cool - There was no well-documented open source repo for an ML accelerator that performed both inference and training None of us have real professional experience in hardware design, which, in a way, made the TPU even more appealing since we weren't able to estimate exactly how difficult it would be. As we worked on the initial stages of this project, we…

I love getting cool swag from hackathons and I also love designing PCB's, so when my friend asked me if I would design hackathon badges for a large game jam in singapore, I was absolutely down! The theme of overglade was a "The game jam within a game", pretty cool concept right! High schoolers from around the world were flown out to the event by hackclub after they spent about 70 hours designing their own game. These badges needed to be really cheap and simple, because we were going to manufacture about a hundred in a pretty limited amount of time. I went with a zero-power approach, which…

It took me a few years of fits and starts but I've finally got my DIY persistence of vision bike light to display video! I designed and built the PCB for it and wrote the code for the wifi streaming of video frames with a bit of help from Claude. This was actually one thing I was dreading as I was hitting a wall being burned out on this project. With a little bit of Claude's help in getting the ESP32 wifi stack working It's finally finished! Some tech specs: Using an ESP32 42 LED's per strip, 4 strips total spaced 90 deg apart. Angular resolution of the image is 1 deg so it updates all 168…
