Raspberry Pi $25 PC Goes Into Alpha Production 137

Posted by Soulskill from the perhaps-not-vaporpi dept.
An anonymous reader writes "Game developer David Braben caused geeks to get excited back in May when he announced plans to develop and release a $25 PC. It is called the Raspberry Pi and takes the form of a USB stick that can be plugged into the HDMI port of a display ready to act as a fully-functional PC. Two months on and the spec of the PCB layout has been finalized and an alpha release has been sent to manufacture. Any doubts this PC wasn't going to happen should now disappear as this alpha board is expected to be almost the same as the final production unit. Although we don't know a release date as of yet, the Raspeberry Pi Foundation is promising images of the alpha boards in a couple of weeks."

  • I'd much rather trade the HDMI for some sort of Ethernet, and maybe a few GPIOs or something.

      Great, but the point of this is to actually be hooked up to a monitor to use it as a computer.

      It's not a "game console" nor is it meant to be a microcontroller like you apparently want to use it as.

      • The alpha and the $35 version "B" will have 2 USB, a built-in USB hub and Ethernet.

      • Actually I think it'd work well as, say, a NES/SNES/Genesis emulator. Hook up a USB gamepad, compile znses or whatever you're using, and you're set. Not sure, but it might even be able to pull off playstation 1 and nintendo 64 emulation. That would be a treat.

    • You're thinking Arduino [arduino.cc]. If performance is a concern you can try the Arduino-compatible ChipKIT 32 [digilentinc.com] from Digilent, which is an Arduino-compatible device using a more powerful PIC microcontroller.

      • I don't care what it was "made for" - I'm talking about what I'd want to "use it for".

        That's the point. All of these little microcontroller type units are good - but when you start wanting to put some heavy-duty services on them, they fall short. For $25, I'd much rather have a machine that I can run a "real" Linux system on. HTTP, SSL, SSH, Perl, Python - whatever. Much better development environment than the embedded microcontroller-type stuff. Even for things like Robotics, etc, too.

        • How exactly are you going to connect your alarm system, sprinkler system, thermostat, garage door opener, etc..etc to a device with only an HDMI and USB connector?

          Sure, it's a $25 PC.. you want a $25 PC to do everything a cheap smarthphone can do? Probably you can develop one device under $25 that can do all you want and drown in money. Try taking the device and the specs and figure out WHAT YOU CAN DO WITH IT, instead of complaining because is not what you need, needs that probably you have already sorted out with something else which is *gasp* actually designed for what you want/need.

I don't want to have to install/learn a new development tool/language/environment to use something like Arduino. It also doesn't have all the services and support I need on-board. It may be "designed to" interface to my sprinkler, but does it have a whole LAMP stack in it, that would let average-joe-developer develop a robust web-based application for a sprinkler control system?

            • I agree with you on the HDMI since theres not a lot of TV or monitors with that available in developing nations where this device would be actually useful. I'd say (taking numbers our of my ass) that the share of conventional ctr/hdmi TVs is 60/40. BUT, it does have composite video out.

              So - I'm just stating my personal opinion of the device. I could never foresee any desire to connect it to a TV and use it as a desktop. I could see a HUGE opportunity for a tiny, $25, "full" Linux machine (none of this flakey uCLinux crap), in an embedded space.

              Try plug computers/servers from sheeva and marvell, they have more grunt and additional things like WIFI and BT, even homeautomation interfaces.

    No screen so you attach it to HDMI port. No input device unless you attach it via USB. No internet unless you attach it via USB, no storage unless you attach it via USB, you also have to connect the power cord (can it even run off battery pack?), etc, etc.

    Remind me again why this isn't just something to be used as a garage door opener or sprinkler timer? Sure it's only $25, and would be fun for hobbyists, but by the time you add all the rest of the needs for basic programming and interaction I don't see it fulfilling their grand vision of a "computer" in ever students hand. It's only slightly more useful than the Linux liveCD that runs off a USB flash drive. It also stretches the definition of "computer" if you have to add all those things to make it useful. Seems an old pentium or x386 would be more useful in their current state and cheaper as well (free). I'm not discrediting the whole idea but I think their grandiose vision is a bit off.

    • I'm pretty sure it's powered from the HDMI port, and I think anyone who intends to use this probably has, or can get, a cheap(probably free) USB keyboard/mouse setup. I see these in the trash and on Craigslist for free all the time.

      As far as the internet, it's a bit troublesome that I don't have a USB wifi adapter, but I'm sure I can grab one for $20 @ some big box store, bringing my total 'working computer with net' cost to about $50.

              The only way we're able to get away with playing MPEG4-ish video on cheap, low-powered portable devices these days is because of the amount of work being done in specialized hardware instead of with software.

    • It's low power vs 200-350 watts for a used 386 or pentium, the screen and keyboard are meant to be left at the station(at the school maybe) and shared by who ever is using it. and yes it will need at least a few gigs of flash. Try fitting a XO in your pocket.

    • Add an ADC, an DAC and a few binnary I/O ports and you can have an alarm/garage controler, but to have a PC like we define it now, you'll only need to add networking.
