Some photos from today's hike in the mountains. To escape the fog.
It was very very icy at the bottom. And I was super happy to have my micro spikes.
The way up was pretty calm. Right the #silentsunday I had desired. At the summit there were a bit too many people and I didn't see proper motives. So I just enjoyed the view and the really warm temperature.
On the wa…

A stunning winter landscape unfolds in this breathtaking scene, where a snow-covered trail winds its way through a serene forest. The trail, blanketed in a thick layer of pristine white snow, is bordered by tall evergreen trees that stand like silent sentinels, their branches heavy with fresh snowfall. The sun shines brightly in the clear blue sky, casting a warm glow over the winter wonderland and creating a beautiful contrast with the cool tones of the snow. In the distance, a valley stretch…

The ridge, partially covered in patches of snow, offers a stunning vantage point overlooking rolling hills, dense forests, and distant mountain ranges. The clear blue sky stretches endlessly above, adding a sense of openness and freedom to the scene. The hikers, dressed in colorful outdoor gear, stand near the edge of the ridge, their…

On a more positive note, my home now features a #vacuum robot running the open source #Valetudo cloud replacement. The guide on how to do that was surprisingly easy to follow. Some light soldering, a bit of flashing that's pretty similar to rooting an Android device, and it's done.
And becau…

A black PCB roughly the size of a USB stick with pin headers, a button, a jumper header, and a micro-USB and USB-A socket. Next to it, a smaller PCB that provides a 90º breakout for the pins for robots that have their debug port mounted in a less accessible location. The PCB layout is available on GitHub at https://github.com/Hypfer/valetudo-dreameadapter/tree/master/pcbs/dreamebreakout.
A screenshot of the Valetudo web interface; the left shows a map of the apartment with rooms in different colors. It is heavily blurred, because you all don't need the floor plan of where I live. The right side shows controls for the robots to set operation mode, fan and water use, issue commands to the dock and show statistics for the last run.
