I smell like bananas.

Mesh radio After my last round of testing on the window sill, I realized we need to talk about how these radios actually talk to each other. Mesh radio is basically just small devices passing notes across town, bouncing the signal until it reaches the right person. The two main firmwares we use right now are Meshtastic and Meshcore, and they handle [...]

I only found out about a couple of guys working with mesh networks because they hopped into the local maker space discord, which immediately caught my eye. It turned out they were forming a new nonprofit focused entirely on mesh radio, so I decided to tag along to the first official founding meeting for the JKPG mesh group, the exact same crew that [...]

I found a great deal on a pair of Tapo C246D cameras recently and couldn't resist picking them up. They are these dual-lens HybridCams that combine a wide-angle view with a motorized telephoto lens in one unit. Getting them integrated into Frigate turned out to be a fun little project, mostly because of some specific authentication quirks and how [...]

My C: drive was screaming for help. Between Docker, several Linux distros, and general dev bloat, the ext4.vhdx file had ballooned to nearly 600GB. Since Windows 11 doesn't have a move button for WSL, I had to do it the manual way. Here is how I moved my Ubuntu instance to my D: drive. All terminal commands are executed in a PowerShell terminal [...]

Since migrating from Google Photos to Immich, I’ve been steadily reclaiming the features I actually used. One of the most glaring omissions was the ability to use my Google Nest Hub as a dynamic photo frame. I wanted a hands-off pipeline: I add a photo to a specific Display album, and it appears on my Hub automatically. No manual casting, no login [...]

I have for quite some time now been thinking about measuring the water temperature in Lake Vättern. One step on the way was the temperature sensor in the much smaller lake Rocksjön that's located in Jönköping. That was back in 2013-12 years ago-and I have not done anything since then relating to LoRaWAN and temperature sensing. But this summer, I got [...]

As previously mentioned I did som exploration of ESP32 mesh functionality and RGB leds for a project involving the local maker space where i failed to force mesh node status. After I gave up on that idea I managed to create som fun stuffs with the LEDs instead. The code is available here First iteration was to just have the LED blink in a chosen [...]

The local makerspace has a project for an upcoming light parade that will be held in the old ex-industrial area where we have our space. The idea is to have a bunch of ESP32 devices meshed together with RGB LEDs creating synchronized effects across the parade route. To make this work, I needed some nodes to always be root nodes (connected to the [...]

For several years now I have hade a string of Neopixel RGB Christmas lights in the Christmas tree that was controlled by an old Python script on a Raspberry Pi. Since I would forget how to set it up between Christmases I simply bundled the string and the RPI with the box and just started it up the next year. This year I got some extra Christmas [...]

I have previously posted texts regarding my adventures in RGB-panel land, first here, and then here. To make the office a bit extra Christmassy this year i decided that I wanted to display some scrolling text (no problem at all) with emoji (great problems). The fonts supported by drivers for these panels have letters, and just the boring ones, not [...]
