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)
