I am baking my own bread for years already, but in the past I did it mainly with a bread baking machine using commercial yeast. September 2017 I started my own sourdough, and over the last couple of months the breads became better and tastier. Important is a slow fermentation of the dough. Usually it takes at least 16 to 24 hours from the first dough to the final loaf.

Finally, after 30 years of service for Rohde & Schwarz, I had my last day in the company. A small “good bye” celebration with a surprise present.

After more than two years 24/7 the volume on my server degraded. One of the three hard disks crashed. Luckily there is some redundancy using Synology Hybrid Raid, and I am now trying to repair the volume. 5 TB of data at risk …
Once successful, will check the defect disk. Still should be under the 3-years warranty from WD.
Today I finally received my guest license for the Philippines. As it is based on my “old” German call sign DK4TB, I will be operating under the call DU1/DK4TB. My next planned visit is from Feb 6th to 13th, 2016.
After I just completed my first own-built quad-copter, here a few details to share about this project. Having the DJI Phantom 2 V3 for aerial photography and a ready built 250 Storm racing drone, I was looking for a FPV mini-copter to fly indoor and outdoor, using brush-less motors and a robust carbon frame. My choice was XELITES ‘s XE180, a 180 frame (motor to motor distance 180 mm).

Racing drones are becoming more and more popular, and it would not only be interesting to know, how fast they can really go, but also which parameters have a major impact on their maximum speed. When I searched in the net, I couldn’t find clear answers and had to work out something by myself; so here is my model. To be clear, my intention is not to get absolute precise numbers, but more to understand the physics behind, and to have a tool to get realistic estimates and comparisons of flight parameters for different quadcopter models. If you are not interested in the details, just scroll down to the end of the page, where I show the final formulas and some calculated examples.
