A lot of projects you can create with raspberri pi
Webcam Video streaming: This project shows the interface a web cam to the Raspberry pi, so that the video can be viewed from any place on the local network
a Face Tracking Camera with Pan and Tilt Control using Raspberry Pi: in this project, a face in real-time monitoring of camera is developed by using the Raspberry Pi. Two servo motors are used to pan and tilt the camera control. A camera module for Raspberry Pi or a simple webcam can be used to capture images
Follow-up Robot Ball: This project shows a ball robot of follow-up. This robot manages the images of the ball processing them and consequently follows the ball.
MeArm is a Robot Arm: Fits into a small pocket and constitutes a small robotic arm functional. This project because it shows the construction of a robotic arm to scale using a body acrylic and 4 servos connected to the Raspberry Pi.
Projects with Raspberry pi with which you can paint
Light laminated Plotter: The Plotter of Glowboard was built with a piece of sheet of 120cm x 60cm Glow-In-The-Dark, a step, 64 UV Leds controlled by a MAX7218 joined a Raspberry pi. The leds are attached to a wooden bar that moves over the sheet. A small web server is used to receive images and controls the Leds and the step so that the images are represented.
Plotter made of recycled parts you design a plotter using recycled parts of old CD readers. The proyetco uses old optical drives, recycled from old obsolete equipment to use their engines step by step, and made a little chart plotter, controlled by WiFi, of these engines, a servo, four bridges H and a Raspberry Pi. HF has made a complete description, including all the source you need is available on its website in German.
