Here’s a really cool AI experiment. The moving head will talk to visitors while the head follows them…
Thomas says,

Sycophant explores the relationship between viewers and a human-like robot. The human head is mounted on a motorized base which moves along a track. As a viewer walks by, the head follows on the track, while plying him or her with a cornucopia of compliments such as “I really like your hair” and “You look really hot!”

Here’s a cool mosquito helicopter that is better than the one from Radio Shack…

…using the ingenious BladeRunner double-propeller system which relies on a coaxial rotor to make piloting the ‘chopper as easy as stroking a tame chipmunk. A three-channel digital remote controls up & down motion, forward & reverse, turning left & right and even allows the Mosquito to hover.

With two frequencies available, you could feasibly buy a pair of them and have Airwolf style sky battles, though you’d have to rely on the glowing green “eyes” to scare your opponent out of the air.

Here’s a review of Radio Shack Rescue Helicopter which can fly indoors pretty nicely.

The only thing is that it is very unstable and cannot land…also you cannot really go forward or backward…just hover and randomly it goes…

Here’s a cool robot made from coat hangers…

Kinda reminds me of a golf cart, neverthless, very cool.

I found some cool looking circuits at this website here’s one of them that
detect levels of water by shorting…kinda nifty~

This circuit not only indicates the amount of water present in the overhead tank but also gives an alarm when the tank is full. The circuit uses the widely available CD4066, bilateral switch CMOS IC to indicate the water level through LEDs. When the water is empty the wires in the tank are open circuited and the 180K resistors pulls the switch low hence opening the switch and LEDs are OFF. As the water starts filling up, first the wire in the tank connected to S1 and the + supply are shorted by water.
