Project suggestions:
1. Lidar (Light radar)
Idea: Measure distances by illuminating a target with a light pulse. c=299792458 m/s.
Material: laser pointer or collimated LED, photodiode,
Goal: Distance > 10m and precision better than 100 micron.
2. Wireless communication
Idea: Electrical signal -> LED -> air -> photodiode -> Electrical signa
Material: LED, photodiode, cut USB cable
Goal: Demonstrate connectivity of two devices with an air gap of 1cm.
3. Levitation of a macroscopic object with a feedback circuit
Idea: Stabilize a levitating magnet with a LED and photodiode that measure its height.
Material: LED, photodiode, two coils, magnet
Goal: stable levitation for 10 seconds
4. Bio sensor
Idea: pulse sensor or pedometer that pick up vibrations from your body
Material: Sensor, Op-amps
Goal: Reach high sensitivity to reveal interesting dynamics of your body
5. Analog differential equation solver
Idea: Solve a non-trivial differential equation with op-amp based feedback circuits
Material: function generator, op-amp
Goal: Show that your circuit yields the correct answer to a non-trivial equation.
6. Cell phone wireless charger:
Idea: Transfer significant energy in free space with magnetic field or optical field.
Material: Variac (for safety) and solenoids
Goal: Show that the phone is charged in an hour
7. Balance a pen standing on its tip
Idea: Stabilize an unstable object by driving or active feedback.
Material: pen, platform, solenoids
Goal: stabilize a pen beyond the Heisenberg’s uncertainty principle. (6 s)
