I recently found my old Shockflyer RC-plane and decided to get it back in duty. Unfortunately the receiver seems to be broken and I had to get a new one. But the model was still using the analog 35 MHz technology and I don’t want to invest in this anymore. Should I buy a new transmitter? […]

Well. At least the first heating circuit in my house. It is now controlled via homematic. And because I have an in-floor heating system, it wasn’t that simple.

Dem reclaim, anti-cloud, mein-content-gehört-mir Trend folgend sollte das dann auch nicht bei blogspot, tumbler und co. sein, sondern eben hier.
