Water to Wine Illusion Box



Have you ever wished that you could turn water into wine (or at least fruit juice). Well now you can with this magic mystery box. All you have to do is pour in water. Then inside the box a bunch of magic happens. Finally out comes a fine glass of wine. It is a simple illusion that uses water pressure and air pressure to switch the drinks. It can make for a fun party trick to amuse your friends.

Solar Power Tools



Solar power is a great way to get electricity out to a remote project site. One simple way to do this is to use a solar panel to charge the batteries of your cordless power tools. In this project, I am going to show you several ways that you can do that.

Unwashed Hands Alarm



You have probably seen signs in a restroom that tell people to wash their hands. But how often does that sign go ignored. Here is a humorous way to find out. In this project, I made an alarm that goes off if someone forgets to wash their hands when they use the restroom.

Personal Cooling System



Summer is hot. And we all need to find ways to cool down. So I built a thermoelectric cooling system that can mount to your wrist. A thermoelectric element acts like a miniature refrigerator. It can turn electricity directly into a change in temperature. By adding a heat sink, you can improve the efficiency of the cooler. This apparatus gets mounted to your wrist right above your radial artery. At this point there is a lot of blood moving near the surface. By cooling this point your blood helps to distribute the cooling effect over your whole body. It looks ridiculous, but it works.

Motion Activated Sprinklers



Do the local animals think that your front lawn is their personal toilet? Do ninja assassins keep trying to sneak into your house? Keep these unwanted visitors away with a motion activated sprinkler system. As soon as they step into your lawn, a passive infrared motion sensor detects the intruder and turns on the sprinkler to chase them away.

Handheld Confetti Cannon



Confetti is a great way to add to a celebration. But just throwing a hand full of confetti in the air is boring. You should fire it out of a confetti cannon. All you need is some PVC pipe and a few fittings. You can use it to shoot confetti, rice, bird seed, flower pedals or even candy. It is perfect for parties, parades and weddings.

USB Powered Drill



I like to keep a small tool kit in my car in case of emergencies. In it I have a small 4.8 volt drill. It is small and portable but there isn't a convenient way to charge it in my car. So I made a simple USB charger cable for it.  I cut open a USB extension cable and connected the red and black wires to a DC power connector that matched the drill. This let me charge the drill from any USB port. So I can now charge it from the phone charger in my car.
