Raspberry Pi Uses?
When the Raspberry Pi was announced I went and bought a pile of them. Now they sit in my apartment, unused. A long while back I got the hard floats working but now you can get that standard. I got it running videos pretty good but now there is an XMBC installation.
What to do, what to do? There is a pretty decent looking 3D-printed case with “LEGO feet” I really like the look of. Plus, the latest LEGO Mindstorm bricks are mostly unlocked– with USB and Bluetooth support– so those are potential resources for a project…
A while back I did make an automated paintball turret. It used a pretty dinky netbook as its brain so I am not too worried about the Raspberry Pi and its 700MHz ARM CPU. I am more familiar with the x86 mobobs so optimization may be a (fun) hassle. Also, since it generates so little heat, it will be a lot easier to build a case to protect it from enemy fire. Hell, if raw processing power does become an issue I can always throw in a tiny network switch and combine a few of the little guys (I was thinking USB-to-USB but, after thinking about it, USB 2.0 only does client/server so efficient polling may be an issue… I do not know).
Well, I have to decide. Perhaps it would be a good project to do with The Womantm…
A team of people (including a 6-year-old) have clustered 64 of these bad boys. They were cool enough to include a really nice how-to so maybe I will take a crack at it over a weekend.
The Pi can now be clocked up to 1GHz plus it is officially supported. You can go higher but, according to the organization, you risk your hardware.
Been playing with some robotic and media center software a lot as of late which gave me a few ideas:
- The Raspbery Pi as a robotics platform/controller. Nothing new there but if I combine it with motion/depth detection (see OpenCV with stereo web cams) I could make an automated paintball sentry… or worse!
- A portable media center powered by the ‘Pi. With a decent battery (say, this happy ‘lil fellow), USB-powered HDMI projector, and some cheap speakers (if the projector does not provide them) I think you could have a decent setup. Well, decent enough for what it is to make me happy, any way.
- Control the LEGO Mindstorm from the thing. All the Mindstorms come with excellent hardware for their intended audiences/purposes. With that said, CPU and memory are limited. There are many ways to control your Mindstorm Brick via Bluetooth and/or USB. Since the ‘Pi is so light I see no issue with just sticking it on top of the whole assembly, with a battery, and using that to control the Brick, which controls everything else. Blam-O, instant my-first-programming and robotics project!
- Minority Report-style interface. Holographic technology– and price– are not there just yet but with a different display (say, projector with a large screen) this is very doable. There are even a lot of tutorial for similar projects out there already using OpenCV or the Microsoft Kinect.
