identifying STM32F103C clones:
The STM32F103C micro-controller has become so popular that you can find plenty of pin and code compatible clones. The issue is when they pretend to be genuine STM32.
We will see how to identify counterfeit STM32F103C, using the top marking, decapsulating the silicon die, but also from inside with a firmware which will check the value and behavior of some registers.
real power vs. apparent power:
We all know voltage times current is power, real power, but don't forget the time component since the RMS values will only give you apparent power, and this is by a power factor different.
introduction to 3-phase 4-wire power distribution:
After showing the tools used to protect myself against the sparks coming out of mains we will see the magic behind three-phase four-wire power distribution and why my custom electricity meter, the spark counter, cannot be used for such installations.
creating an open source hardware logo:
What better than a logo on your hardware to show ir is open source?
Such a logo provided by the Open Source Hardware Association even already exists, but the rights on it were not clear, no vector version and footprint were provided, and it's quite hard to draw in electronic CAD softwares.
So I decided to create my own open source hardware logo for my electronic designs.
It's simple and can be drawn easily in any CAD software, but the generator already lets you customize it and export it as vector graphic or as footprint for your electronic CAD software.
