After a year plus of playing around with this side project, I have finally launched what I'm calling Mimir (mimirframe.com) It's a self-hosted platform that turns e-ink frames, old tablets, TVs, and monitors into ambient displays. No subscription. Open source. #opensource #eink #raspberrypi
Mimir — Self-hosted display management
One small server on your network, driving every screen you own. Local-first, open source, no cloud account.

Wonderful time outside London picking up a couple of new SOTA badges and enjoying the opportunity to play radio with friends new and old. The best thing about this hobby is always the people we enjoy the time with along the way!
George Smart, M1GEO@m1geo.com · 2mo agoGreat to catch @k5em.com on a layover and activate #sota G/CE-005 and #pota GB-1850 today, along with @G5RFJ - we had a blast on both HF and VHF mixed modes! #hamradio

Fun morning knocking out a Pasadena area favorite SOTA summit with John before the last day of SuperCon

I was in Los Angeles this weekend for @hackaday-feed.bsky.social SuperCon and had the chance to meet up with some of my favorite SoCal SOTA peeps @n6ara.bsky.social and Mark KD7DTS and chat on the sofa. Don't miss the earlier episodes! youtu.be/VBG_cy7qeCM

What an inaugural post on bsky.app. A (the) major glacier collapse at Bichgletscher/Kleines Nesthorn.
Never seen before perspective of a tornado in Arnett, OK by our research drone on May 18th. Watch the full video here on YouTube: youtu.be/NGD2e741Riw
Does anyone else find the Discover feed totally useless to discover anything? All it shows me are posts I've already read from people I already follow.
A little sun, snow, and family therapy today. Beautiful day to be in the mountains.
Bambu's firmware shenanigans are making me rethink ever recommending one again. They have to backtrack on it, or lose the goodwill of the 3DP community that is "open source but willing to give on value sometimes", which is not an insignificant sector.

The first aurora of 2025 danced in the night sky last night.
Fippin' the breakers is the easiest way to find local RFI - or to find out it's not local. When doing so, remember to check your radio power supply too, especially if it's of the switching type. Helped a ham in the neighborhood hunting RFI for him to realize it was the radio switching power supply.

Last day to order a SotaCAT for the year! Get WiFi control, click-to-tune spotting, and SotaMAT integration on your KX2/KX3. We have a few in stock still; any in-stock orders today will ship tomorrow, then we're taking the holidays off. store.invertedlabs.com
single sided PCB, fully fabricated on my bench in under an hour using a fiber laser. i’m STOKED.
🎶 Christmas time is here 🎶 c/o gpt: Receivers strain to hear But noise is oh so near Glowing reindeer on the lawn Make pure reception disappear I tune and adjust my knobs To find that perfect tone Yet flick’ring bulbs and singing shrubs Turn clear bands into drone Oh, static noise is here...
For the past year or so, I've been working with @ab6d.bsky.social to turn his SotaCAT design and concept into a ready-to-buy hardware design. After a couple of pre-order rounds and testing, today I opened the web store for general SotaCAT consumption. So what is SotaCAT exactly?
