Pi to Go: Hot Raspberry Pi DIY Mini Desktop PC Project 134

Posted by timothy from the tab-a-slot-b-fruit-x dept.
MojoKid writes "Hot Hardware recently set out to design a custom mini desktop system with the popular Raspberry Pi single board computer. People have configured the device for a variety of applications, from micro-servers to low cost media players. Basically, the goal was to turn what is currently one of the cheapest bare-bones computer boards into a fully enclosed mini desktop computer that could be taken anywhere without the need for cabling or setup. This small DIY project is just one of many examples of the flexibility of the Raspberry Pi's open architecture. And to think you can even run Quake and Minecraft on it."

    They used an off-the-shelf project box made the old way in a gloopy factory? Luddites. They should have 3D printed a case which would have taken days and weeks of design and tweaking and dozens of prototype runs. All that to end up with a ridged wobbly blob. That's the future.

        Three^W four kinds of people. A RPi pulls only around 5 Watts of power. Sufficiently low that it's you can make it solar-powered, which can come in handy for those of us who occasionally suffer multi-day power outages or want a "computer fix" away from civilization The main power draw, in fact, would be the display.

        Another use of a RPi is for a low-power satellite system, for things like word processing, email, or recipes in the kitchen. Take an old monitor, tape an RPi to the back of it, stuff a WiFi ethernet USB dongle into it, and connect it to the SAN. Add keyboard and mouse as needed (or use Bluetooth).

        At $25 for the minimal Pi and $35 for the loaded version, you can practically hand them out as party favors. It's almost certain that whatever you plug into them will cost more than the computer itself, but fortunately. with the possible exception of HDMI, a lot of us have spare parts gathering dust anyway.

    • That was my thought, despite what the summary says, this isn't particularly portable. You still need to get a monitor and a keyboard. There are other better projects for this. I get that it's Pi, but seriously, this has been possible for quite some time.

      Wake me up when somebody can do something similar to the OpenPandora on a budget. I've got one and it's great, but the cost is still on the high side due to the small number of units ordered.

        For instance, it's not a "Solid Tie" for the ethernet. The Pi has ethernet over USB, so it can't be compared with the Black having the Ethernet over a dedicated PHY interface.

Sure the Beaglebone has some onboard storage, but you're going to run up against that measly 2GB of storage pretty fast.

      Indeed. However, power usage is something to consider. A model B RPi uses a piddling 3.5 W, whereas a Core 2 Duo E6850 by itself consumes nearly 20 times as much power (65 W). If you're running it 24x7, that's the difference between 17 kWh per month and 327 kWh per month. With an electricity cost at about 12 US cents per kWh (US average), that translates to a US$37.20 per month difference. The cost of the Pi is thus more than made up by electricity savings in just a month. Other factors, e.g. the fact that

        Per my calculations, R-Pi will cost 30 cents/mo, and an E6850 will be $5.70/mo. However if you close the lid of the notebook it draws much less, about 23-25W, and then the costs drop down to about $2.50/mo. Nobody worries about such a piddly expense.

        For example: 3.5W * 24 hrs/day * 30.5 days/mo = 2.562 kWh (30.744 cents/mo.)

    The Raspberry Pi is not open hardware at the board level (schematic but no gerbers) nor at the SoC level (no full reference manual on the Broadcom BCM2835 device) nor at the boot level (booting and boot options are handled by the proprietary VideoCore IV) nor at the GPU and DSP levels (the VideoCore is entirely closed/under NDA). In fact, the only fully open thing about Raspberry Pi is its old and rather obsolete ARM11 processor.

    So why exactly is anyone associating the word "open" with Raspberry Pi?

    Far more open is the similarly priced BeagleBone Black [beagleboard.org], which provides full gerbers, full SoC reference manual, and full open source boot control (U-Boot). The BeagleBone Black's TI SoC does have a closed GPU, but since the board isn't aimed at running games nor consuming media like the Raspberry Pi is, it hardly matters. And the BeagleBone Black is far more capable in almost every other respect.

    It's cool that Raspberry Pi has helped to bring ARM board prices down, but it shouldn't be called an open platform when it's mostly closed.
