I'm pretty happy with how this turned out! I found an old hammered bronze timpani/kettle drum shell that had been sitting outside, cleaned it up a little, and turned it into a hanging lamp.

I hooked up an ESP8266 board running ESPHome to the debug UART on the Weatherflow hub. A couple of lines of lambda code in the config, and it's now filtering only the sensor report JSON and broadcasting it over UDP. From there, Home Assistant integrations listen, parse, and present the data.
I opened up my Weatherflow hub and found some useful test points. The red module is the main microcontroller with wifi and BLE radios, and the module with the metal shield is the radio that actually listens for the Weatherflow sensors. The two modules communicate via I2C.
I got interested in meshtastic this past week, but I've been trying not to buy new hardware for new obsessions while I still have drawers full of parts.
The datasheet for this GPS receiver is dated 2008, but I hooked up power and serial, and within a few minutes it was detecting sats even indoors.
I didn't know the Habitat ReStore (building material thrift store) had an electronics section until recently. The other day I found this cool "computer math" calculator with bin/oct/hex modes for $1
When digital storage oscilloscopes were new and expensive, you could buy a digital front-end for your analog scope. This Heath/Zenith SD-4850 is a really nice example.
Replacing the worn out right-click switch in my old MS Trackball Explorer turned into more of a project than I'd planned. I've repaired a lot of stuff, and I've never encountered plastic this brittle -- posts and clips just shattering from the touch of a q-tip.
Starting the year off with a hike up Enchanted Rock. Wish I'd brought a radio -- could've got a combo SOTA/POTA activation
