Circuits Day 1: Hex Schmitt Trigger

On our first studio day we experimented with the Hex Schmitt Trigger circuit. All together we built five separate circuits through varying the capacitors, resistors and adding additional oscillators. We started our project log where we will note down each circuit we build and the sound/effect this produces, our soundcloud will be a space to document our findings and will be important as we build the orchestra. A highlight of the day was playing with the 10p outputs from crocodile clips, this meant that a human (or in the case of the video below… a toy bust of Lenin) holding both the coins completed the circuit and generated the sound. By rubbing your fingers and moving them around this also altered the sound of the oscillator. Children and families loved having a play with this, holding hands or touching noses to complete the circuit… scientific fun!
