Raspberry Pi is a low-priced ($35-$40), credit-card sized single board computer that was originally developed to teach schoolchildren basic computer science skills.
As with these type of things, it has become very popular among hobbyists for building all manner of computer projects. The example given above is but one. It is very popular with home automation projects (remote control of lights, air conditioning, etc.) and the like.
Not something for everybody, admittedly, but still, your inner geek has got to say "cool."
That IPhone looks ancient :p
Anyhow...good post....Rasp Pi, Adurino are fantastic and actually easy to use. Been building with them for a couple of years. Low cost, very flexible, lot of possibilities.
I actually finally thought of a good project that I can justify buying a Pi to use (and a 3d printer too).
I don’t want to give away too many details, because it might be a product I could patent, but I want to use the Pi to control a device with motors that move a mounted piece of equipment, like a camera, on 3 axes of motion. Then the Pi would connect wirelessly to an app on a handheld which had the pan and zoom controls, and controls for a few other things that the software on the Pi would control. I would also need the Pi to transmit video output to an external screen.
Seems pretty do-able to me but I’ll probably save it for a winter project when I’m stuck indoors with a lot of time on my hands to putz around.
bkmk
Don’t like the seeds in raspberry pie. I’m holding out for Blueberry Pi.

The Pi2 makes a marvelous industrial controller!
For what this girl did for her Gramps a super cheap Android phone would have been a better deal.
I’m using them around here for remote cams.
Been playing with the idea of writing a Java app to make a P2P backup for FR. Everyone goes to walmart and grabs a cheap phone and sticks the app on it and it connects to their wifi and you have a distributed backup for FR.
The cheap Androids I got have a dual ARM core at 1.4Ghz ... plenty of oomph and they come with a 4GB sd card and that’s plenty of data space for such an app.
Lots o fun for sure!
You don’t need to be a genius to do these things either...hey, If I can do it...so can the average Freeper. :-)
I’m currently reading/responding/browsing the net on a Raspberry Pi 2.
The iPhone is better but the Apple gear is locked down tight....better to use a lesser and cheaper system that is totally open.
[OK, the GPU in the Pi is not fully open source but it’s still usable as a black blob]
I gave a demo of the Pi2 last month at my local Ham Radio club meeting. Everyone had fun! I love showing folks how easy it is to do this stuff.
Can you attach a port extender to it to get more usb ports?
Yes, I use a 10 port USB hub and all ports work fine.
I recommend a powered hub with at least 2.5 amps. The hub will power the Pi at the same time so you can run without a separate supply.
Home network is mostly Gentoo. I'm thinking about doing a mail/file/print server on one of these small computers. Nothing urgent, just watching things evolve, but I like the idea of low power for those functions. Low traffic (small network), so speed is not much of an issue. Using an old laptop for that function now (880 days uptime).
>>> Can you attach a port extender to it to get more usb ports? <<<
The Pi 2 has 4 USB ports but I’ve added an extender for 4 more ports. No problem: the UNIX operating system picks it up and integrates it into the system automatically on power-up.
Yes, but if you shoot deer with it, the DNR’s gonna come after you :P
My kids’ middle school has a Raspberry Pi club.
