Running a Raspberry Pi from 6 AA Batteries

Interfacing a Raspberry Pi with a Radio Controlled car was on my list of projects so I need to experiment with powering the Pi from batteries. I had a number of basic requirements.

Running The Raspberry Pi On Batteries

This is a wider topic than High Altitude Ballooning – there are many applications where operation is needed away from a mains supply – so I thought it would be good to describe my approach to the problem.

Using a webcam with the Raspberry Pi

There is a lot of recent motivation to do image processing and computer vision tasks on the Raspberry Pi.
Luckily OpenCv is already built on Raspbian and Wheezy.

Use the Raspberry Pi Serial Port to Connect to a Device

This example shows how to create a connection to a serial device, write data to the device, and read data from the device.

Control your Raspberry Pi robot from a web-connected device

Last issue we built a Raspberry Pi robot. This issue, we’ll create a Python web application that lets you control your bot using a first-person view

Connect Rasp PI to LED light
