With a recently renewed spark of interest in electronics, I’m now starting to solder stuff and build more permanent devices than before with breadboards.
But with great power comes great responsibility!
Some of these devices may eventually be powered on 24/7, without adult supervision. While I was pretty confident I could unplug a breadboard while watching it, I don’t have the same peace of mind considering permanent devices.
Worried by videos of raspberry pi catching fire, and other diy electronics going really wrong, I started looking for guides on... you know, safety. Alas, I found nothing with enough details.
I know not to tinker with mains. I know transistors can get really hot (burned a finger once). But that’s it really.
As the various comments pointed out, there’s no hard and fast rule for safety, and I should test my circuits. Makes sense.
However, being new to the field, I’m unsure what to test for. Overcurrent could be one thing, but further than that, I’m lost.
What are the main safety tests that a circuit design should go through before being left unsupervised?
