Right, #Hackster round-up time - and it's a big 'un, as I didn't post much last week owing to being absolutely run off my feet at #EmbeddedWorld2026
First up, a new Notecard from Blues (formerly Blues Wireless), which offers Wi-Fi, cellular, and non-terrestrial network (NTN) satellite connectivity in one. They were showing it off at the show, though it's hard to get a good signal to LEO through the Messe roof...
Speaking of cellular connectivity, the Walter Cat 1 Bis is an upgraded version of the Walter development board - now offering faster, better cellular.
Design files have been promised, as with the original Walter.
Then there's the Argo CM5, which I covered back when it was just somebody's random project - and now it's heading to @crowdsupply as a teeny-tiny carrier board for the #RaspberryPi Compute Module 5.
That brings us to today, where I started with a look at a project from Taras Woronjanski to port the #Arduino UNO Q libraries to Rust.
Sticking with #Arduino, there's the Forgetfulino - which lets you compress and upload the source code of your Arduino sketches for storage in the microcontroller's flash - meaning you can easily recover it again when you find the board abandoned in a drawer three years later.
Or is that just me?
Rod Hull, of @futurewas8bit fame, has designed a tester for old microcomputer power supplies - which looks like "a microwave that's had an idea."

And, finally, there's the TinkerNav - an Espressif ESP32-S3-based sub-$100 dev board offering GNSS satellite navigation reception with on-receiver RTK correction support for centimeter-level accuracy.
And it's all up on the #GeminiProtocol too:

As a bonus for #GeminiProtocol users, the index page also has a little event diary from my trip to #EmbeddedWorld2026 - and the all-too-eventful journey *back* from the show, from which I am still recovering.
Oh! And while the videos from #EmbeddedWorld2026 are still working their way through the editing process, #Hackster has put together a little teaser.
That teeny-tiny DJI camera I took is great. Shame about the oik in front of the lens, tho'!
Finally, before I let you go, a call for participation: #Hackster is running a #competition dubbed Invent the Future - and has 300 (three hundred!) #Arduino UNO Q boards to give away, gratis, to entrants.
If you fancy a shot at picking one up, you can find out more on the official competition page - you've got until the 5th of April to apply, but until the 30th of August to complete your project.

@ghalfacree I have a short form for the location on my fileserver where the firmware is: something like.
f/p/c/avr/m328/pandora
I usually leave a sticker somewhere on the project.
which is just enough of a hint to get me back into trouble.
