03 – cutting costs
Log from Universal undervoltage lockout up to 34V input
What is the aim? This log is all about: How can we make the whole board cheaper while keeping all the features and not killing its safety functions. This all refers to the early v0.2 version which is by no means optimized yet! Ways to cut costs I try...

Motor Control and Current Measurements work very well.
Log from Open Concentrating PV Solar Tracker Controller
Motor controller and current measurement This will be a long log, so I want to summarize: The motor controller of the “single board” works as expected and we can get a current measurement which is good enough to detect blocked or damaged...

Generating video signals on a microcontroller with correct amplitude and impedance.
Hacker page by danjovic
Composite video standard defines a signal with 1Vpp amplitude under a 75 Ohms. From that signal 70% (0.7V) is the amplitude of video information which stands above a 0.3V pedestal, while the synchronism information (sync tip) corresponds to the remaining...
