I recently picked up a few VATTENSTEN low voltage 5V LED strips from IKEA because I figured they’d be easier to integrate into a USB-powered Raspberry Pi or Raspberry Pi Pico project. I was right!
I wanted to display my Hackaday Superconference badge without continually burning through disposable batteries, or having to cycle through rechargeables every other day. A fellow conference-goer shared this LiPo holder design which just fits into the badge’s AA receptacles and provides a sturdy plane to which to strap a bigger…
In the final day of Hackaday Superconference 2023, I feel like I started to get into the groove of the conference. During the afternoon, I found a spot to play around more with my badge while within earshot of a couple of sessions that–frankly–were beyond my level of understanding in…
Second day of Hackaday Superconference 2023 was a bunch of fun. I had the delightful surprise of unknowingly chatting with Benedetta Lia Mandelli and Emilio Sordi the day before only to see them on stage presenting the Soft Actuator Orthosis talk. They seem like neat humans working on ways to…
First day of Hackaday Superconference 2023 down and I’ve had some time at home to tinker with the code on this year’s badge. The badge itself has some nifty analog-ish oscilloscope-like features that I’m sure I’d understand and enjoy more if I knew more about electrical engineering. However, I do…
After I built the cardboard stock sorting shelf, I had about a week of breathing issues as a result of poor ventilation from the sawdust and particulate in the air in my garage. Resolved to avoid another week of feeling crummy, I bought a beefy fan and have eventual plans…
Well, I finally got around to updating my CO2 Monitor to take advantage of the latest APIs in the Flipper Zero firmware. (It wasn’t quite as bad as I thought it would be 😅) Now it even has its own application icon!
I picked up an Aranet4 Home CO2 sensor on a Black Friday sale and have finally had the chance to run a commercially-calibrated CO2 sensor against my DIY CO2 monitor on the Flipper Zero and found that my sensor needed some calibration.
I’ve been working on a lot of hardware projects lately: making text-to-speech appliances work on transit vehicles, making software for internet-connected signs, prototyping tools to help me make good health decisions, and building out my go-sensors libraries to support physical environment sensors. I’ve spent a lot of my time as…
In April 2021, I had a problem at work: I didn’t understand how our on-vehicle application communicated with the text-to-speech appliance to make next stop announcements.

I’ve been playing with environment sensors for a while to help me understand how factors of air quality correlate to my health. In 2019, I had a particularly bad asthma attack that was exacerbated by wildfires in California. Since then, I’ve learned a lot about how 2.5 micron particulate matter…
I was tired of fiddling with the fold-up case that my RadioShack 22-810 multimeter (photo not mine) came in. The probes were a pain to fit into the case properly and I also wanted to have the option to use wires with Dupont connectors to play nicely with my breadboard.…
For multiple reasons–my asthma, air quality, and COVID-19–I run several air purifiers throughout my home. I run a whole Levoit Core 300 air purifier on top of my desk, which typically is useful for collecting my cat’s dander in addition to putting clean air out close to my face. However,…
My cat has an addiction to drinking directly from the tub’s faucet. We’ve tried to get him nice water dishes and electric pump water fountains, but he just craves that good, good tub water. (And is extremely vocal about when he wants to drink.)
