Color Control For Rgbw Led Stripes
For using RGBW LED stripes properly, I was missing an easy control of color and brightness. Based on the PIC16F1827 I developed a control card using the serial line for communication and a Raspberry PI showing the Web based control page as part of my home control system.
Domestic Central Heating Radiator Efficiency Optimiser
IoT device to log input and output temperatures of a radiator. The plan is to get a display of temperature differential. One of the radiator valves can then be adjusted to change the water flow until an optimum drop is achieved. That is about 20F or 12C according to the Web, but Analytics on the data can help determine ideal.
