Witty cloud board:

See article on [witty cloud][_posts/smarthome/2019-10-15-creating-pcb-witty-cloud.md], but i’m still not sure what wen’t wrong there.

It took me a while to get over that issue and order new pcb with better design.

Din case for Raspberry pi

See previous lesson. Never apply force before visualy observing. SD card slot broke from it’s mount and device became unusable…

Magichome LED strip controller

Don’t use cheap soldering irons. Or you would end up with dead IC’s.

Buck-down modle

One should add some margin for error, at least few millimeters, so device made in chinese cellars would fit case made by diy 3d printer.

Kitchen over re-wiring

That’s not my fault rather designers of it (or 10 years of constant usage):
