Turn a #RaspberryPi into a personal VPN / @Raspberry_Pi
Great tutorial from LifeHacker on creating a personal VPN with the help of a Raspberry Pi. “The Raspberry Pi has very low power consumption, which makes it a great always-on virtual private network (VPN) server. With a VPN, you’ll get…
Serial communication between #RaspberryPi and #Arduino
Great little tutorial on powering an Arduino from the Pi’s 5V pin and also communicating via serial from the GPIO pins. Well worth a look if you want communication between the two to be faster. As the article points out,…
Changing the hostname of your #RaspberryPi
For those people who (like me) have more than one Pi, and even for those who have more than one SD card, the ability to change the hostname is invaluable. Here’s how you do it. You need to change two…
Using a #RaspberryPi as a Ninja Block @Raspberry_Pi
“Ninja Blocks are tiny cloud enabled computers that can sense their environment by receiving input from a variety of sensors & can affect their surroundings by controlling lights, power sockets, and other actuators.” The company making the Ninja Blocks have…
Volunteer your #RaspberryPi to analyse SETI data / @Raspberry_Pi
Daniel Carrion at Burde View has been getting “BOINC” up and running in order to use his Raspberry Pi to analyse telescope and other astronomical data. “BOINC is open-source software for volunteer computing and grid computing. It uses to the…
Warn people off with a #RaspberryPi motion sensor and sound effect
Here’s a quick tutorial on using an ultrasonic range sensor to detect nearby movement and play a sound to ‘warn’ people off! Sensors and Raspberry Pi: I2C connection.
Use #RaspberryPi RAM as swap space
This is interesting. Someone over at Linux Journal is using “zram” to turn half the Pi’s RAM into a swap space. They even claim to have removed the swap file entirely, which should improve the life of your SD cards.…
Cheap PIR Sensors and the #RaspberryPi [reblog]
Another interesting post from Matt Hawkins over at Raspberry Pi Spy about getting a cheap-as-chips PIR motion sensor working with Python and the Pi. Cheap PIR Sensors and the Raspberry Pi – Part 1 | Raspberry Pi Spy.
Completely Wireless IP Camera with battery for #RaspberryPi
A great instructable on how to create a wireless IP camera powered by a solar battery pack. Includes command-line commands to get it up and running with Motion. Raspberry Pi: Completely Wireless IP Camera. Solar Battery Pack, WiFi, Logitech Camera,…
