In this semester, here are the main projects in Principles of Technology:
CD Drive Junkbot
By disassembling CD drives, we learn about electricity, circuits and electrical components.
These components are then used to make a junkbot robot of your own design.
What is a conductor? How can you tell conductors apart from Insulators?
Conductors allow electricity to flow through them, Insulators prevent electricity from flowing.
Motors allow you to convert electrical energy into rotational movement.
LEDs are Light Emitting Diods and convert electricity into light. They have a negative and positive lead. LEDs are polarized and must be wired correctly or they will not light
Switches allow you to open or close a circuit, turning the circuit on and off.
2 color sticker design
Make custom stickers that are sized to fit where you want.
The images on the stickers comes from photos and other images of your choosing.
In this project, you have to find a picture that would convert properly. High contrast, relatively simple designs work better than complex images.
By putting a box around the image in Open office, you get an outer boundary for the picture.
Cigar Box Music Player
Using a cigar box, cardboard, speakers and an audio amplier, make a music player that will connect to your iPod, phone or MP3 player.
In this project, you started with a commercial cigar box.
Some of the modifications you made:
Painting the box inside and out.
Measuring and designing a custom cardboard insert for the speaker and amplifier system.
Attaching the speakers
Wiring the amplifier
Powering the amplifier
Sketchup
Design objects in Sketchup with accuracy.
Combine designs into assemblies to make a 3D model of the Mendocino Motor before building it.
Drawing the designs with accuracy
Combining the shapes into assemblies and subassemblies
Mendocino Motor
You make a magnetically levitating, solar powered electric motor from raw supplies.
Cutting the block to size
Drilling the center hole in the block
Measuring the wire with a wooden paddle
Wrapping the rotor
Wiring the motor
attaching the solar cells
Arranging the magnets
Balancing the motor and making it work properly.
