I’ve unlocked a new achievement as a blogger, or a new milestone as a life-form. As a dinosaur telling the same old stories over and over again. I started drafting a blog post, as I always do since a while: I do it in my mind only, twist and turn in for days or weeks […]Read More Infinite Loop: Theory and Practice Revisited.

We are using the freely programmable controller UVR16x2 (and its predecessor) UVR1611) … .. and their Control and Monitoring Interface – CMI:The CMI is a data logger and runs a web server. It logs data from […]Read More Where Are the Files? [Winsol – UVR16x2]

The CMI has become a little Data Kraken itself: Inputs and outputs can be created for CAN bus and Modbus, […]Read More Logging Fun with UVR16x2: Photovoltaic Generator – Modbus – CAN Bus
This is one of the perennial top search terms for this blog. Anticlimactic answer: Yes, because input and output are determined also by economics, not only by physics. Often readers search for the efficiency of a refrigerator. Its efficiency, the ratio of output and input energies, is greater than 1 because the ambient energy is […]Read More Can the Efficiency Be Greater Than One?
It is the the duty of a Webmaster to allocate URIs which you will be able to stand by in 2 years, in 20 years, in 200 years. This needs thought, and organization, and commitment.
