Check out this low cost project. This video will show you how to transfer sound over light! Yes, this is possible. You'll transfer a sound with a distance of 5 meters, but you may experiment on greater distances if you'd like. You'll need a laser (or an LED) for this audio project, one Opto transistor (or resistor), one 3-volt battery, two mono audio jacks, and some alligator clips. Just watch this cool electronic audio experiment and try it out yourself.

Check out this video to see how to use the popular ES&S iVotronic touchscreen voting machine. You'll see how to begin the voting process by having a poll worker activate your ballot, then you can vote in private. So, if you are tired of using hand ballots for your county in voting elections, watch this to upgrade to an electronic system. It's easy to use, and this is your manual.
