Tin whiskers: tiny crystalline structure that grow on surfaces, finished with tin. Can be observed with zinc as well. That stuff can really cause deadly shorts, and nobody (yet?) know why they grow like that! https://nepp.nasa.gov/WHISKER/background/what-are-whiskers.jpg https://nepp.nasa.gov/WHISKER/background/ #engineering #science #electronics

Design Patterns Pitfalls https://egoless.tech/design-patterns-pitfalls/ Learn when design patterns do more harm than good.

Another great SW engineering article from our fellow blog! #software #engineering

Learn it Yourself https://egoless.tech/learn-it-yourself/ Stop asking others and learn to learn by yourself.

The main thing you should start with when entering technical field - master a skill of self-learning. Practically speaking - RTFM!

Do not repeat this at home!

Continuing highlighting a battery power related topics. This time: undervoltage protection of a Li-Ion cell. The undervoltage can cause damage for your batteries. The circuit above consumes few microamps and shutdowns a load if a voltage drops below threshold. The threshold is set by voltage divider (node A) to 3V. https://www.analog.com/en/technical-articles/battery-protection-circuit.html #electronics #engineering #basic P.S. Turns out that LT1495 is quite expensive. MCP6441 looks the same, but I didn't test it yet. Also, pay note to hysteresis (R5), this eliminates a bounce and increase the noise immunity when A and B voltages are close to each other.
