After years of making screwdrivers and teaching people to repair electronics, we just made our first electronic tool. It's been a journey for us to build while hewing to our repairable principles. We're really excited about it. It's a USB-C powered soldering iron and smart battery power hub. Super repairable, of course. Our goal is to make soldering so easy everyone can do it: https://www.ifixit.com/fixhub We didn’t want to make just another iron, so we spent years sweating the details and crafting something that met our exacting standards. This is a high-performance iron: it…

Here's a "behind-the-scenes" look at my development of a cool sensor during my PhD (electrical engineering). This sensor is only about 1/3 of my total research for my degree and took about a year. I've been on HN for a while now and I've seen my fair share of posts about the woes of pursuing a PhD. Now that I'm done with mine I wanna share some anecdotal evidence that doing a PhD can actually be enjoyable (not necessarily easy) and also be doable in 3 years. When I started I knew I didn't want to work on something that would never leave the lab or languish in a dissertation PDF no one…

Hi HN, This is my attempt to fix groggy mornings by lowering my bedroom CO2 from 1700 ppm to ~900 ppm. I designed a simple, 3D-printed fan duct that directs air under the door to improve air circulation. A note on the design process: I used CadQuery, a Python library for creating parametric 3D models. I didn't know tools like this existed and highly recommend it if you can program; it turned out to be more convenient than manually iterating on prototypes in a GUI. The project is open source and the post explains the full build. Happy to answer any questions.

Hey guys, A couple weeks ago, I was in Shenzhen, China for a hackathon and on the first day, we all used the one-day PCB fabrication to make PCB badges to wear during the event. I decided to go a little crazy and make some cool 3D alchemical-cosmological badges. It's 3 PCB's stacked on-top of each other that's connected using testpoints on each board. The innerboard has a 10 cent CH32V003 MCU that powers the WS2812B neopixels on the outer rings using the testpoints and shines through using exposed soldermask. If you have any questions about how the design works, feel free to let me know!

Hi HN, I’m part of the team building Sniphi. Sniphi is a modular digital nose that uses gas sensors and machine-learning models to convert volatile organic compound (VOC) data into a machine-readable signal that can be integrated into existing QA, monitoring, or automation systems. The system is currently in an R&D phase, but already exists as working hardware and software and is being tested in real environments. The project grew out of earlier collaborations with university researchers on gas sensors and odor classification. What we kept running into was a gap between promising lab results…
