New supplier of bits n pieces for the #RaspberryPi – BitWizard

Netherlands-based (and therefore Euro currency) site BitWizard are selling some nice modules. For example, breakout boards for the I2C and SPI pins and an LCD and control panel board.

Very reasonable shipping costs, too. I looked at their Arduino-compatible bridge adapter (the Raspduino) and, for an Arduino-sized product costing 20 euros, the postage was only 3.60 euros.

Controlling a #RaspberryPi with real life redstone in Minecraft / @Raspberry_Pi

“We’ve seen computers built in Minecraft out of redstone, the game’s version of electricity, circuits, and digital logic. We’ve even seen a few redstone contraptions controlling real-world devices. [Angus]‘ build, though, takes things to a whole new level. He’s created a bridge between Minecraft circuits and their real life counterparts using a Raspberry Pi and a PiFace.”

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 secure access to your home network when you’re on the go and can use it for secure web browsing when you’re on public networks. Here’s how to roll your own VPN with the Raspberry Pi.”

Serial communication between #RaspberryPi and #Arduino

Serial communication between Raspberry Pi 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, by using USB to connect an Arduino to the Pi, you introduce a latent delay between the two. Well worth a look for your Pi-Arduino projects.
