Now I just want to automate this record-and-process in a little homelab setup where the image can be updated and displayed on a monitor in my room with each NOAA pass.

Grainy image of swirling clouds.

Grainy image of clouds overlaid on a colored image of the US.

You can record these beeps and ticks as a .WAV file and pass them through decoding software to get the image. It's a little grainy, but tools like SatDump can clean and contextualize it with overlays.

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!

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

Classroom of students watching a live demo of using a signal generator to make a buzzer chirp at different frequencies.

Classroom of students observing a presenter (alex) and slide deck titled "technical HCI + microcontroller basics"

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!

You can enjoy haptics while charging devices with my arm-wear! (beautifully shot by John Zich at University of Chicago)

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.
