I've been toying around with (distracting myself with) SDR a bit more recently. Here's a go at using it to capture NOAA-19 as it passed over Chicago tonight. This is an unencrypted weather satellite you can just grab images of the planet from!

Today I upgraded the mini rack: it now has SDR capabilities courtesy of a CaribouLite, for portable radio fun! Full video on the setup and remote SDR with GQRX here: www.youtube.com/watch?v=Hz2W...

🎉 Workshop at #CHI2025: "Sensorimotor Devices: Coupling Sensing and Actuation to Augment Bodily Experience" If you’re passionate about sensorimotor interaction, wearables, or motion-coupled feedback, join us! 🗓️ Deadline: Feb 13, 2025 AoE 🔗 sensorimotordevices.github.io

#meshtastic on the RP2350 Stamp? It's more likely than you think!

Week 1 of our "hci engineering" class is underway. Had the privilege of subbing in for @pedrolopes.org and tried to bring his energy with live coding, circuits and demos 😄 This year, we are trying out teaching on the XIAO RP2350 and have new assignments on tinyML, SDR, and high-frequency sampling!

Where This Xmas Card’s Going, We Don’t Need Batteries!

A fresh start on Bluesky: I am Shan-Yuan, a PhD candidate passionate about "haptics" (touch, texture, force), which we have mostly given up with touchscreens & VR/AR headsets. I re-envision and build new hardware that enables fun and dexterous computing interactions (hoping to start a new lab!).

It’s refreshing to see both social (don’t feed trolls) and technical (no outrage maximization newsfeeds) insulation from bad faith actors’ baiting strategies. Durable communities are built around consent, discovery, and safety not around manipulation, surveillance, and extraction.

I am recruiting a postdoc! The research emphasis is participatory design for decision-making interfaces. Check out the two project descriptions on my website. people.cs.uchicago.edu/~kalea/prosp... The position is through UChicago’s Data Science Institute. datascience.uchicago.edu/research/pos...
