Below are a few of my first experiments with using a Hex Schmitt Inverter (IC 74C14) to make my simple synth circuit. For my generator I alternated between testing with copper wire and magnets and using a wall plug variable power supply that has settings for 3, 4.5, 6, 9, and 12 volts each at 1 amp. Most of the experiments using the plug-in supply were using the 3 and 4.5 volt settings.
For this pendulum assignment I worked with Xuedi Chen and Anne-Marie Lavigne. Here are some of our ideas and sketches for devices powered by our pendulum made in class:
First are the pendulum measurements:
1st idea: Acme rocket launch
Have a match or maybe a bunch of matches attached to the swinging end of the pendulum. At its lowest point it will strike a rough and combustable surface. This will ignite the fuse on the rocket.
2nd Idea: A pendulum powered stirrer and/ or masher.
This device uses our pendulum to drive a fulcrum and lever system. The pendulum is on one end of the lever. The other end will have our spoon or masher attached.
3rd Idea: Pendulum powered camera
Using the same lever system as our second idea the pendulum operates the shutter and the film advance of a manual film camera.
