In this video, Barron Stone outlines some safety concerns when working with electricity. This course does not prepare viewers to safely work with high-power systems like the electrical wiring in a house.
- 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.
