PART FINDER FRIDAY – Power jacks! These ubiquitous power jacks are excellent for connecting a standard power supply plug to your project. In general the center contact is positive and the outer is negative. Its common for these jacks to have a switch on the ground, so you can disconnect an internal battery or similar when power is plugged in. We use these in nearly every kit!
