How Ferrite Beads Work - EMI Suppression
Educational

  If you are working on a project where you want to get rid of EMI from entering an input you might want to look into using some ferrite beads, they can help you out in removing high frequency noise from your circuit. The ferrite looks like a variable resistor that has no impact on your circuit at low infrequence and starts to conduct to short out higher frequencies. It

Raspberry Pi Model Train Controller
Cool Gadgets

  The Raspberry Pi is a very powerful heart of many cool projects including this Raspberry Pi Model Train Controller by MrNotbuyinit. The description of the electronics starts at around 2:35. The prototype interface from the Pi is a simple breadboard which looks to be ideal for quick and easy additions and modifications. The Pi is interfacing with a port expander to get more digital outputs out of the Pi.
