- Working with electronics is a ton of fun,
but it can also be dangerous.
Electric shock can cause serious injuries
or even death, and at the very least,
being shocked is not a pleasant feeling.
The example circuits I build in this course
use relatively low voltages so you can safely
follow along and build the circuits yourself.
This course will not train you to work
on power distribution systems like AC wall outlets.
If you want to make changes or repairs
to the wiring in your house, don't do it yourself,
hire a licensed electrician.
As you start designing and building your own circuits,
please be careful, especially when working
with voltages larger than around 50 volts.
Above that level, the risk of being electrocuted
increases significantly.
As a safety rule, I never work alone
when I'm building circuits that are somehow
connected to a wall outlet.
I always have a friend nearby who can pull the plug
on things and rescue me if something
were to go wrong.
I've also found that it's fun to share the experience
of building electronics with a friend.
