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. 🌝

Switched to Niagara Launcher on GrapheneOS and can highly recommend it for productivity and peace of mind. Bonus points for being free and without ads!

Explained my son how electric circuits work and now his #minecraft crafting table is glowing in three colours.

Hooked up the Meshology 868MHz whip antenna to a #nanoVNA and got the following results. SWR 1.247 LOGMAG -19.12 dB SMITH 50 Ω Will be using this on my Lilygo T-Echo at 98.8% power acceptance nearly perfect.

The Berlin Swapfest is now on! Feel free to just come through to @c-base.org no registration needed! We’ve got some great items to swap this time thanks to our awesome swappers.

Mounted the omnidirectional 868 MHz +3dBi antenna on the rooftop pole today. Also tested the solar panel with the #LoRa hardware and it keeps it at 100% on a sunny day at least. Will assemble the rest next week. #Meshtastic

How short do you want your coax cable? Yes! #LoRa

Testing the mobile setup with a LILYGO T-Deck in my car. #meshtastic Quite some nodes around this area.

Temperature and humidity sensors also working now (ELV-AM-TH1 head). #esp32 Firmware: github.com/l5yth/elv-bm...

Lots of activity on #Meshtastic in Berlin @c-base.org #KøpiBleibt.

Managed to get the ELV photo diode light sensor working on Linux. Can detect room illumination by firmware now. Next step is to enable the #LoRaWAN functionality to send this to the gateway for further processing.

According to Larry Fink, Blackrock, the Ukraine will be a "beacon of power of capitalism." (2023) This aged well.

Tuesday next week we will have our first Stammtisch after @protocol.berlin v2 on board of @c-base.org Please RSVP on @smokesignal.events preview.smokesignal.events/did:plc:cspd...

We’re now a little less than two weeks from the second Berlin Swapfest at @c-base.org! There are still a handful of tables left for those who wish to swap electronics! Register for a table or to attend today! www.swapfest.berlin

Wireless mesh has been around for 50 years, and BLE mesh is nearly a decade old at this point. The problem is the complexity of nodes within the mesh. Bluetooth is prone to spoofing attacks, and without regular updates for each node, the network will only be as secure as the least secure node.

How to flash an ELV-BM-TRX1 (dnt-TRX-ST1) #LoRaWAN MCU on Linux? The Windows ELV Flasher tool cannot be used. The ELV module is not automatically recognized because the VendorID (18ef) / ProductID (e02e) is not registered in the driver.
