Ponder Puzzel

The Ponder Puzzle is a group project that I made with four other people during IAP 2005. The idea was simple. We were basically making a 3D puzzle map that could talk. The hard thing was that we made everything from scrach, and not everyone was very sure how to actually build the thing to fulfill our goal. We developed our ideas, and did an amazing teamwork. We won the first prize at the end. The wonderful times were not only when they announced that we won, but also the entire time when I was working with these great people.

Since only I had some electrical engineering experience on my team, I was in charge of the circuitry design.

This is the circuit I designed to use only one battery and one speaker in series with seven sound recording chips. Op-amps here act as input adders to add all the signals sending from the sound chips and pass them on to the speaker.

Blinking LED circuit. I used a 555 timer to change a 9V DC to a square wave.

Working for the whole night until 6am in the morning is like this.
