Why does water short out PCBs? (i.e. Why doesn't electricity follow the path of least resistance?) Great answer, Russell! Question: how come the low 4.2VDC of portable devices manage to ionize water and pass such a huge current (miliamps) in order to burn out electronics? Could you please provide a sample simple calculation? For example, I believe one needs 10kV to ionize 1 cm of air gap! |

DIY: What is required in order to save a picture captured from a CMOS image sensor to a digital format? IMHO: No way ever! Whole firms of hundreds of persons work on writing drivers for those things. Just get webcams @ $30 e.g. amazon.com/Logitech-960-000585-HD-Webcam-C310/dp/B003LVZO8S |

Carrying out multiple synchronous tasks with a micrcontroller @supercat, the idea behind 2) in my post (and it is far from being mine idea) if that if the interrupt has to do heavy work, it generally sets a flag and exits. Then, when the round robin loop reaches an if(flag){slow block of code}, the less time-critical, but interrupt-dependant code is executed. Refer to picoOS - bottom halves. |

How to measure the capabilities of a wall adapter? Unfortunately, I don't happen to own a handful of 24W resistors :( |

Mains on a single core wire? The worst thing is, they will appear to work (as the current draw will be small), but later, when two wires touch or insulation is somewhat damaged - boom - sparks and soot. Can also happen with touching resistors. |

How to measure the capabilities of a wall adapter? @W5VO, thank you for your care of the question. However, protecting it removed the answer of a new user, user2020 I believe, that contained the interesting idea of dumping the power into the heatsink of a transistor. How do we bring it back (or you think it is a bad answer?)? |
