In The Radio Domain
Log from Reverse-Engineering the milight on-air protocol
The first step in reverse-engineering any radio protocol is to listen to it on the air. The advent of software-defined radio makes this much, much, easier than before. For this project I've used a nuand bladeRF board and the GNURadio software stack,...

Some Maths
Log from Solar Sand Converter - Solving the sand problem
So according to wikipedia "The reflectivity of bright aluminum foil is 88% while dull embossed foil is about 80%", this is far better than I thought. Markus Kaysers SolarSinter Project, appeared to use 4 lenses of about 6ft x 4ft total area, while I...

Using a Counter for the ISR
