transister amplification

A research team from the University of Hamburg has invented a way to produce a Coulomb transistor (single electron transistor). The transistor is inexpensive and has varying applications.

The displays come in the clear and mirrored variety and both are equally amazing.

Each year over a million people attend Maker Faires around the world, but few people get a chance to present at one. I'm going to share a little about my experience presenting at my local Barnes and Noble Mini Maker Faire so makers everywhere can learn how to be better presenters.
