Desktop Fan Design and Fabrication Goal Design, fabricate, assemble and test a small oscillating fan for a desktop Resources Students are provided with a Sparkfun Inventor's Kit, which contains an Arduino microcontroller, an assortment of electrical components, a small DC motor, a small servo motor and an instructional manual. Students will be able to fabricate structural components from a small sheet of 1/8 inch thick acrylic. The acrylic can be cut with a laser cutter from two-dimensional drawings. Required features 1. The system must be safe. For example, there can be no potential for injury by touching spinning fan blade(s) 2. The fan should use the DC motor in the Sparkfun Inventor's Kit. 3. The orientation of the fan must oscillate back and forth up to 180 degrees (+-90). 4. The fan must operate without requiring the user to directly interact with any computer code, for example by typing on the computer keyboard to specify the rotation angle or fan speed. 5. The user can adfanspeed (speed of the DC motor). Extra points .The fan can have an on-off switch and a second switch to start/stop the oscillation. .The user can change the extent of oscillation (e.g. -30, +/-45, etc.) The final prototype has cool or entertaining features The quality of workmanship (fit and finish) is high. 'The fan would be considered "cool" by people with no technical training.
