Resistors

The idea for AddOhms #8 has been around for quite some time.  I’m always trying to find ways to explain why current limiting resistors are necessary.  So while working in the shop one day, I decided to play with some LEDs and a bench-power supply.  Then I decided to record what happens.

The other night I happened to see a tweet come across my twitter stream from Joe Walnes (@joewalnes) about a resistor color code tool he created.  You can find it at the clever domain resisto.rs.  Type in a value and see what the proper color code should be.  This is great for when you need to go searching through a pile of resistors and want to make sure you have the code right. http://resisto.rs/ Nice job @joewalnes!…
