Keep yourself safe from angry components
When you are using components that are new to you, or you don´t really know how to wire, if you plug them into your circuit first thing to do:
DON¨T TOUCH THAT COMPONENT!! Touch it with a plastic bag!
Sounds stupid? Believe me, its not! Doing this saved me from burning my finger with a zener diode yesterday, well, saved me the second time as the first one, I didn´t do this...
Remmember! Plastic bags can save you from angry components!!
