This weekend I found myself digging through the AT Protocol specifications and the Bluesky Personal Data Server (PDS) implementation. In doing so, I discovered that I could setup a website that is fully hosted on Bluesky.

This weekend I reached 3,000 miles running in 2025 after initially accomplishing the goal in 2023. I wrote a few words about the unique challenge of doing a difficult thing a second time, and why you have to make hard things possible before you can make them normal.

Make it Possible, Then Make it Normal
This past Saturday I went out for a 12 mile run with a few friends. Absent the beautiful fall colors on display this time of year in North Carolina, there was nothing especially notable about this par...

ICYMI I wrote about how FPGAs are configured and why that can lead to some interesting SPI routing on Lattice iCE40 development boards.
**Interesting SPI Routing with iCE40 FPGAs**
I wrote about iCE40 FPGAs, and why the way an FPGA is configured can lead to interesting board design decisions. @mith.ro's Fomu is a useful study due to eschewing a USB-Serial chip for accessing the FPGA and SPI flash.

I think @golioth.io may be the first custom Brick in @officialarduino.bsky.social App Lab 👀
We make use of both the BLE and Wi-Fi connectivity on the UNO Q to proxy data for BLE peripherals, stream data from attached sensors, and perform network-based positioning with Golioth Location!

We just released v0.2.0 of signy, our signed URLs library for embedded devices! This release includes support for ESP-IDF, which enables some new interesting use cases, such as leveraging the esp_http_ota component for OTA firmware updates from @golioth.io.

I whipped up a case for the @officialarduino.bsky.social Uno Q.
* MakerWorld: bit.ly/43BpU3G
* Printables: bit.ly/4qBBoho
* Thingiverse: bit.ly/3Jz6uFU
What's running *on* the Uno Q?
Stay tuned...👀
