Enter Raspberry PI, the smallest computer you could own for 25$-35$. The Raspberry Pi is a single-board computer developed in the UK by the Raspberry Pi Foundation. The Foundation’s goal is to offer two versions, priced at US$25 and $35 (plus local taxes). The Foundation started accepting orders for the higher priced model on 29 February 2012 The Raspberry Pi is intended to stimulate the teaching of basic computer science in schools.
And it’s powered with Linux. No Microsoft here, and there is talk of Android support!! Of course, It’s not rocket science to figure out the other applications what this brilliant little device could bring. Considering it’s got HDMI built-in, this is the most inexpensive upgrade for your big screen TV (And finally have a browser that doesn’t suck ass!!). Just throw in a wireless USB adapter and a wireless keyboard/mouse combo and voila!! You have a smart TV.
And considering it’s small size and low voltage, its perfect for a robot’s brain too. It would be neat if someone who revamp an old HERO-1 robot with the Raspberry PI as the brains. Toss in VNC , a webcam and wireless and you have your own very robotic drone on the cheap. This could open a lot of opportunities for home made CNC’s as well.
