I am an inventor.
I build a lot of things to (1) make my life easier or (2) make the world a better (and less dull) place.
Here are some of my recent projects:
- After nearly rear-ending the car in front of me a couple weeks ago, I decided to build a device that would give me an audio signal if I'm about to hit something. The device uses an Arduino, IR proximity sensor, and an 8 ohm speaker. The project is still a work in progress because the IR sensor can only detect 50-100cm and will occasionally pick up water droplets or particle dust on the windshield.
- I'm trying to get in the holiday spirit. Last week, I built a system that plays 10 seconds of holiday music synchronized to christmas lights every time I open my door. It's basically an Arduino hack with christmas lights, a speaker, and a motion sensor.
- A few weeks ago, I took a part a remote control car and built myself a device that unlocks my room door. Using the motor, some metal rods, and a lot of duct tape, I can now open my door from my desk or bed. Now I'm working to connect the same system to an Arduino and audio detector. This way a certain knock combination or spoken word can automatically open my door.
