Great #guide to using a #potato to check #positive from #negative #electrical #current https://diy.stackexchange.com/questions/.. Very funny!
Very interesting #article on a #foreigner living in #shanghai during their #current #covid #lockdown https://jaapgrolleman.com/shanghais-stun.. Worth #reading this #hackernews #comment where somebody #claims their #brother has not #eaten in 2 days now with zero help in sight: https://news.ycombinator.com/item?id=309.. People are literally #starving out there with very little #hope for now.
Awesome, apparently #adsl is #robust enough to even work over #wetstring https://www.revk.uk/2017/12/its-official.. Apparently it can even operate over an #airgap where normal #connections will not work at all! Apparently it works with #alternating #current #ac rather than #direct #current #dc - meaning that it #propagates as a #wave to jump an #airgap ! https://forums.whirlpool.net.au/archive/..
I don't think I have ever seen such large #traces on a #pcb #manufactured *ever* https://hackaday.com/2021/11/08/heavy-co.. Imagine the sort of #current these could sink!
Very impressive to squeeze so much #music into a humble little ATtiny85 #microcontroller ! https://hackaday.com/2021/08/19/custom-c.. #current draw appears to just be 20mA too!
