I use a lock screen that takes a screenshot of my desktop and adds a blur for privacy reasons.

Apparently, running an #SDR on the device is hard to hide with a blur 😂

Upgraded the #SteamDeck OLED from 512GB to 2TB. Since SteamOS is a full Archlinux, I didn't even need a computer to mirror and enhance the SSD. I just used a Thinkpad docking station and an M2 case to attach the SSD.

Tickets for #39c3 were sold out in less than a second. I wish the congress was less gated and also in a city that's not so expensive as Hamburg during Christmas holidays.

Turns out you can fit an optical drive in that cool slice docking station for the X220. So, I went ahead and installed GTA2 from CD-ROM as if it's 1999. 😌

I removed the proprietary BIOS from my new Thinkpad X220 and flashed #coreboot with SeaBIOS. I also neutralized the Intel Management Engine. Bonus: I had spare space on the firmware chip, so I also added Tetris and Doom which I can play now even without any operating system.

Built my first federated app. Each new publicly hosted instace announces their existence, and if correctly configured, will be accepted into the mesh of the meshes ... already seeing eight instances in different regions.

Released v0.5 of the Meshtastic grid dashboard. I decided to add federation to it. Let's see how it goes :-)

Added neighbor info to the meshtastic explorer dashboard. You can see the actual mesh now. Each line is a direct connection.

We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe. signal.org/blog/pdfs/ge...

I bought a #Thinkpad X220 (again) as if it was 2012. This is the rare version with USB3 and an Intel Core i7-2460M. It is also in a fairly good condition.

I'll max out the RAM to 16GB and add two SSDs to 512GB + 2TB. And I'll swap out the TFT screen with an LG IPS display.

I looked up the specs of the Waveshare SX1268 #LoRa hat which is intended to be mounted on a Raspberry Pi through a 2x20 pin header. I did some research and thought it would be feasible to map the pins to a 2x12 pin header of the Odroid H3+.

Charging the #meshtastic solar batteries to 100% before the winter hits. Let's see how long we can stay online.

The RAK WisMesh Tag with keychain arrived today. It has a great form factor and works really great with #Meshtastic out of the box. Did some testing in the neighborhood.

I built a #meshtastic dashboard for local communities over the weekend. It has a chat and map view.

The incredible Berlin ICC opened for 49h this weekend. Designed like a spaceship, served as congress center for 20k people in the 1970s. Today, there is no plan or idea what to do with it. But it's so pretty.

Today my GPIO expansion for the T-Echo arrived, so I can add a temperature and humidity sensor outside the case. All my #meshtastic metadata will contain weather readings afterwards.

Someone instructed AI to send out spam in batches but the agent instead sent out the entire script including API address and tokens. Matches my kind of humor.

C-Base under maintenance. 🌝
PSA:

No Stammtisch today as @c-base.org is in maintenance mode in preparation for the 30 year celebrations.
If you come on board there will be no relaxed conversations with drinks as usual - but you will be expected to work on maintaining the space station ;-)
