The bare-bones $35 computer by a Broadcom engineer teaches programming skills to children.

Broadcom engineer Eben Upton started a foundation with a simple goal: to make and sell an inexpensive computer that could help teach children computer programming.

The result: Upton created the Raspberry Pi, a $35 computer slightly larger than an Altoids tin that's like a blank slate for tech enthusiasts.

Has anyone else noticed that the term “Altoid Tin” has become PC size reference for what used to be “a pack of cigarettes”?

I’m a coach on a FIRST Robotics Team. Our programmer is using one of these on our bot this year for some of sensors and cameras. I’m not sure exactly what for, I mentor the mechanical part of the robot.

Here’s our team website. http://frc3941.techbrick.com/ Personal and corporate sponsorship opportunities are available and sorely needed. PM me if you’re interested.

They shouldn’t call that a mini-computer. A PDP-11 is a mini-computer. This should be called a mini PC, perhaps.

Can’t put components in a pack of smokes though. The Altoids tins can be used for lots of different projects thats why the refer to it. I use them as survival kits. Crush proof and perfect for carrying in a pocket.

A PDP-11 is a bit bigger than a RPi. Probably not as fast either.

Yes, and a Compaq 386 is also bigger and slower than an RPi, but it is a MICRO-computer. The problem is that in terms of computer scale, MINI is actually on the large size. Even the body of the article refers to the RPI as a microcomputer. You might also call it a mini-microcomputer, but the term minicomputer is taken.

I think the Altoid tin is a Brit reference. The Pi is made in the UK. Very few Americans say “tin” even when refering to a small metal box.

I have a hdhomerun prime, and am currently using Windows Media Center. I have media center extenders in the garage, and on the outside patio. I’m hoping to replace the extenders with Raspberry Pi based htpc’s in the future.

Hdhomerun has now updated their prime’s to act as DLNA servers. I’ve looked at using XBMC on the Rpi, but until there is a PVR addin with DTCP-IP support, it’s not worth replacing the extenders.

"Open Embedded Linux Entertainment Center, or OpenELEC for short, is a small Linux distribution built from scratch as a platform to turn your computer into a complete XBMC media center. OpenELEC is designed to make your system boot as fast as possible and the install is so easy that anyone can turn a blank PC into a media machine in less than 15 minutes."

http://openelec.tv/

Available for a number of platforms, including RPi.

I’ve watched this thing come to fruition for quite some time now, the only thing is, I can’t think of anything to use it for. Probably going to use it to control something, but haven’t decided what.

I felt the same way about personal computers in the eighties. The business I worked for in the late 70s had their own computer intranet, which we managers had to file daily reports on, but outside of business, accounting, research, military, and government, I just couldn't imagine all of the things we use personal computers for today.

The life hacker / survival / EDC crowd uses the word tin a lot. Altoids tins are a staple of their conversations.

No doubt. Perhaps we can call them pico-computers. They'll surely get smaller still so we should hold off from using the term nano-computer.

I have one on the den TV running Raspbmc so I can stream video. It works great. It streams 1080p video just fine. I measured the power draw and it will cost me <$5/yr to leave it on 24/7.

Cool, would love to hear more about the project. I have one and got one for my bro for Christmas. They were hard to find at that time, but MCM electronics had them in stock.

It's a great little device. I watched a movie streaming from amazon prime tonight. I haven't gotten netflix to stream over it yet, but working on it. Netfilx uses windows silverlight.

Also, you will need to get a .mp2 license for about $4, if you want to watch any of your movie files in that format. Mp4 and some other formats work fine without the license.

Thanks for the link. I'm planning on connecting it to the real world soon, as I have been playing around with the arduino and netduios boards as well.

Remote controls.

Which type are you using?
Any suggestions?

Right now, I’m just using a Logitech wireless mouse.

I think there’s a way to use your iPhone (or a smartphone in general), but it hasn’t been enough of a priority yet. I had the mouse, and I’ve only had the thing going for 2-3 weeks, and I’ve been busy with other things.

How did you watch the Amazon Prime stream? In Raspbmc? Or just through a browser in Raspian? Other?

I'm using OpenELEC; just playing around for now. Here is a link that will explain the process of adding "Add-Ons". Any version of XBMC should work the same way. OpenElec is the smallest build, I think. The other versions do more, but take more resources.

One thing I discovered, the device must have at least .850 amps or you'll have issues. At 1 amp @ 5 volts through the micro USB, not problems driving a mouse, keyboard, VGA adapter and a small set of speakers.

Another thing, you have to go to audio settings, under system settings and tell it to use analog (headphone/speaker jack) or HDMI. It has unbelievable sound sound and picture for a $35 device. I still haven't tried the RCA video output for comparison.

“Has anyone else noticed that the term “Altoid Tin” has become PC size reference for what used to be “a pack of cigarettes”?”

That is because today’s tinkerers like to build things into Altoid tins.

So when they say “the size of an Altoid can” they mean “You can use an Altoid can as a project box to build it in”.

not computer related.

Hello, I’m looking for freepers with Raspberry Pi’s.

Received my Model B Pi about a week ago. I’ve plugged it into 2 HDTVs. Each of them have a port that is HDIM/DVI and a port the that is marked just HDMI. I get nothing on the screen. I have plugged an RCA cable from the Pi into each of the RCA video ports on each and still nothing on the screen. I tried an old analog TV on channel 3 with the RCA cable and still nothing on the screen. I purchased an adapter to plug my RGB computer monitor into the HDMI port on the Pi and still nothing on the screen.

Next, the Pi came with an 8 gig Noobs SD card from Allied so I’m thinking it must be the card. I format a new PNY card using the recommended SD Association formatting tool and the Noob image from Raspberry Pi org. Still no joy.

Am I in possession of a bad Pi or am I completely inept at anything that involves technology? In my defense, I have taught Microsoft application classes at the college level. I have replaced HDs in computer. I have added RAM to computers. I’ve written HTAs and vbscripts.

The activity lights on the Pi:
ACT = 8 green blinks then a 2 second pause
PWR = continuous red

Since my Pi flashes 8 times. I’m pretty confident that the 8 flashes are associated with:

SDRAM not recognized. You need newer bootcode.bin/start.elf firmware.

I’ve tried three different SD cards. When I purchased the Pi B model I purchased a pre-installed version of Noobs with the Pi B. That one does not work.

I purchased a new 16 gig PNY SD and used the recommended SD card formatter tool and installed Noobs on it. That did not work.

I re-formatted the 16 gig PNY SD and installed Raspbian using the recommended Win32 Disk Image tool. That did not work.

I found a 2 gig SD and reformatted it and installed Noobs on it. That did not work.

HOW CAN I DO A FIRMWARE UPGRADE IF I CAN’T SEE WHAT IS ON THE SCREEN AND I CAN’T GET THE PI TO RECOGNIZE MY PI?

Does putting a fresh OS image on an SD the equivalent of getting the latest bootcode.bin/start.elf firmware update?

Doesn’t the Pi itself have firmware that has to be updated?

Can you confirm my suspicions? Do I have a bad Pi?

Sorry to hear you are having a problem. Sounds like you either have a bad card or it's a firmware issue. Take a look at this link and see if it offers you any ideas. I've had no such issues with my Pi and have used it with several OSs.

If you've purchased the card through Amazon, they have an excellent return policy.
