“Plan 9 occupies an interesting niche in the open source operating system world. It is a full-fledged descendant of Unix, but not in the way that most systems out there are. It took the bones and beating heart of Unix and then built a brand-new cybernetic exoskeleton around it”
Free on Kindle this weekend : #RaspberryPi User Guide from Echo Bay Books
Just for this weekend, Echo Bay Books’ publication “The Quick and Easy Guide to Raspberry Pi” is free for Kindle from Amazon.
UK people click here to get it from the Kindle store on Amazon.co.uk.
International people click here to get it from the Kindle store on Amazon.com.
I’ve not read it yet but from the first few pages on Look Inside, it looks to be a fairly standard text with obvious diagrams, but probably no worse for that. Interestingly, the contents page says that it covers the Pi Store, which means it’s bang up-to-date (for now).
Simple ADC with the #RaspberryPi
Stewart Russell at “We Saw a Chicken” has done a very comprehensive tutorial on using a simple analog to digital converter (ADC) via SPI to read a temperature sensor with Python. It is based on the work for the Quite Rubbish Clock featured on this blog recently.
How Arduino is open-sourcing imagination
This is a talk from a TED conference by Massimo Banzi, who helped invent the Arduino. You can read the original article on GeekBoy.it or just watch the video below.
Now, I’d never heard of TED, so here’s what Wikipedia says about it:
“TED is a global set of conferences owned by the private non-profit Sapling Foundation, formed to disseminate “ideas worth spreading.” TED was founded in 1984 as a one-off event. The annual conference began in 1990, in Monterey, California.”
Create a cloud server with Owncloud on the #RaspberryPi
PetRockBlog has created a tutorial for starting your own Cloud Server on a Pi. It’s not perfect yet (see the comments) but looks promising.

#Raspberry Pi to Arduino via GPIO UART
With most Arduinos (and compatibles) there is a USB port. However, communicating over it introduces some latency. Communicating directly via UART serial is faster. Here’s a tutorial on how to make it happen for you. Raspberry Pi and Arduino via GPIO UARTandremiller.net | andremiller.net.
