Was great fun to be a part of @JennyList ‘s This Week in #hackaday panel show for BornHack radio 102.8 FM last week. Thanks for having me on with @annejan and Mike! https://youtu.be/RHVIUPLQPOY?si=91OXlijU6KbUtXoM

Mercury and copper glow in a vacuum when you shake them. Pretty cool. Lightbulb from the 17th Century.

Hmmm. I have, uh, various bits ... Anyone got a good vacuum pump?

Interesting $10 spectrometer chip that'd make a real nice tricorder addition to give chemical analysis. Probably be a while before its on #Hackaday but.

I has an excite. This dry-looking paper:

https://arxiv.org/html/2605.27250v1

describes a mechanosynthesis experiment where individual carbon atoms were combined into specific straight and branched molecular carbon chains with an STM. This is not just pushing atoms around a substrate. This is atomically precise fabrication of bonded molecules.

In short, the very basis of nanofabrication popularly referred to as "The Diamond Age." I've been waiting a while for this.

Hey @GustavOne - thank you for a wonderful SAO, I just added random LEDs and it looks amazing with added hot glue diffuser!

I am returning a very high end fitness product. The hardware was defective or proprietary software was so bad or intentionally hostile. Did they use AI to design this thing? The lack of printed instructions to troubleshoot how to power it up and if it was supposed to lose all its memory after it died after a few minutes. I lost a lot of time with this. Did they test it before selling it? Not able to use it once.

I'm sure someone already published a quality DIY project on #hackaday and this is why I love open source open hardware.

Hackaday Europe in Lecco, Italy was a blast!

My first ever Hackaday event, and probably not my last 😉

I met lots of people, both old friends and new, as well as some I already knew online but hadn't met in real life yet.
I also gave a lightning talk about what I'm currently up to with my Tiny FABulous FPGAs.

Now, with lots of nice goodies and a cool badge, I'm back home again.
