Dance Pad Mania

Angela and I are making a dance pad. So far, we are still figuring it out. Angela is taping the buzzer and the battery to a piece of cardboard. Angela has to restart the whole thing because she taped the buzzer the wrong side up so the microphone out of which the sound comes out of is blocked by the cardboard. Angela and I are planning to make a hole under the buzzer so that the hole out of which the sound come out of is on the side of the hole in the cardboard. Smart!

WE SUCCEEDED!!!!!!!!!!!!!!!!!!!! WOOHOOO!!!!! Now if you press both sides of the battery the buzzer will start buzzing!

We did this challenge after Judy and Adam, engineers and the hosts of DESIGN SQUAD on www.pbskids.org.

Design Squad Hidden Buzzer Failed

Jennifer and I tried to make the DESIGN SQUAD Hidden Buzzer by getting a piece of cardboard, tin foil, double A battery, masking tape, scissors, buzzers.

We took the wires from the buzzer  and put the wires up against the sides of the battery. It didn't WORK! It vibrated, like you could feel the energy. But it didn't make any noise. Making noise is what it was supposed to do.

Jen is trying to see if the wires from the buzzer need to be more exposed. We learned that masking tape works better than duct tape.

I hope it will make noise next week — we'll try it again.
