Doorbell that takes photos with push-messages

Raspberry Pi is great for doing crazy setups. Being Linux based platform it can take photos, send emails and other messages over internet. Deddies Lab have shared his interesting setup, where he placed a webcam at the front door and when someone pushes doorbell message with photo footage is sent. First of all he hacked in to wireless doorbell where he was able to capture button press with Raspberry Pi GPIO. Then he wrote a simple Python script to send push message with date and time on event. During building there came a thought that seeing message isn’t enough as there is no info on who was at the door. The next thing he added was Logitech C270 webcam which was configured to capture snapshots and short movies. Again, python… Continue reading

Controlling webcam when you are not home

Webcam may be the cheapest way of monitoring your home while you are out. All you need is to leave your PC connected with camera so you could connect to it using remote connection software like VNC or Teamviewer. Ruijc wanted to look after his cat using this technique, but found out that steady camera doesn’t cover all the areas of the room, so he started a project where he would be able to control camera tilt and rotation remotely. He built a simple PIC16F88 microcontroller based circuit which would drive two servo motors. Motors simply tilt and rotate camera to point at any spot of the room. Additionally he added a transistor driven LED lamp, which also can be turned on when there is dark in room. Device is… Continue reading

Arduino Based Robotic Wooden Labyrinth Game

Labyrinth is a very challenging game, where you can compete with your family and friends anytime, anywhere you want. However, if you think that it’s quite dull to play the ordinary Labyrinth, then how about this Arduino based robotic wooden Labyrinth game? This project doesn’t cost you too much, where with around $60 or less, you can build a great Arduino Labyrinth. Actually, it’s the ideal project to start with, if you want to learn about robotics. This game is using two servos and an Arduino to turn the knobs for moving the game surface. By the way, if you already have the Xbox360 game controller, then you only need to program it and modify it to suit with the Labyrinth game, instead of buying it on the market. If… Continue reading
