RPi Garbage Bin Reminder

Automatic Bike Indicators

This project uses an Accelerometer to detect when you are leaning left or right. Depending on if/where you are leaning, it will flash LEDs on the right or left of the bike's rear. Powered by an Arduino and a 12v battery pack (my case 8 AA Batteries). I have made a video on it below. By: User28028 Tags: arduino rgb led 12v adlx345 Favored: 0

Infinity-Mirror Table

An infinity mirror creates a striking optical illusion - a tunnel of light that seems to tear through space. I built this infinity-mirror table using some addressable LEDs, a Particle Photon and easily obtainable timber supplies. Check out the video to see the table in action! If ...
