Did a component or a trace ever went poof in your projects?
Did you ever reversed the battery by accident and everything failed?
Did some components ever lost their magic smoke because of some fails of yours?

Then this section is for you! Here are protective and safety circuits which will help you protect your future projects from going boom.

This section is far from complete, but I try to post as much as i can.

You know more circuits? Feel free to send me them at marco@marco-bastelt.de
