Raspberry Pi Hits the 2 Million Mark 246

Posted by timothy from the chicken-in-every-pot dept.
The Raspberry Pi project that we've been fans of for quite a while now has hit a new milestone: Today, they announced that as of the last week in October, the project has sold more than two million boards. Raspberry Pi is anything but alone in the tiny, hackable computer world (all kinds of other options, from Arduino to the x86-based Minnowboard, are out there, and all have their selling points), but the low price, open-source emphasis, and focus on education have all helped the Pi catch on. If yours is one of these 2 million, what are you using it for? (And if you favor some other small system for your own experiments, what factors matter?)

          I have a few different arm boards including two raspberry pi boards. Power consumption / power efficiency is NOT a selling point of the pi, if comparing to other arm boards. The pi has no low power states, it is full power all the time. The pi also uses linear voltage regulators, so very inefficient.

          My original model panda board has 1G ram, is several times faster than the pi, and uses half the power most of the time, and has the same peak power.

          My odroid U2 is at least 10 times faster than the pi, has 2G ram, and uses about the same power (or a little less) most of the time (but it has crazy high peak power if running at 100%cpu with a massive heatsink). If you pull the heatsink, it thermal throttles to still way faster than a pi, and keeps the peak power consumption pretty close to the pi.

          I don't have a beagle bone black, but I would suspect it is lower power consumption than a pi.

          The selling point for the pi is the community around it is _much_ larger than any of these other SBCs.

      We're in the golden age for software development. I prefer an "open" solution like the Beagleboard but I received an R.Pi v2 for free and have made it part of my low-power dev environment. I'll describe this environment for the amusement of ye 'dotters.

      I installed a $10 hardware clock in the R.Pi and I power the it with a spare power cord from an Amazon Kindle.

      I run Raspbian (Debian) with Icewm DE. I use the R.Pi for coding (Java, C++, Perl, Go) and I push Mercurial updates to a code repo on a Sheevaplug running Debian Wheezy. The Sheevaplug's power supply had failed (typical problem, melted capacitors) but I wired the mainboard to an AC adaptor from a USB hub.

      I've overclocked the R.Pi to 900MHz. This isn't enough CPU to browse the Internet directly from the R.Pi with Iceweasel/Firefox, but Midori and NetSurf work well enough. On a Pogoplug V2 (running Debian, you see the pattern here), I have lighttpd and a Perl program that fetches and summarises RSS feeds for me. I can view the RSS summary from the R.Pi using NetSurf or Midori. (Dillo doesn't do tables well.)

      When I need to do Web research that requires Flash or special plug-ins, I use rdesktop to connect to a VM instance of Firefox (M-Windows XP or Debian) installed on an AMD box running VMware ESXi server. ESXi server is free.

      I have all this running with an APC battery back-up. The APC unit can run for some time with only the ARM kit to power. I have another APC UPS feeding my modem, router, and assorted switches.

      It's a versatile dev environment and it didn't cost much. None of it would be possible without Linux. I'll say it again: this is a golden age for software developers.

    • I work on even older chips. Ancient ones, actually, compared to ARM technology. The controllers I use are 8bit technology, having between 1 and 64k program memory (yes, in Harvard technology) and clocked at up to a stunning 20MHz.

    I like Raspbian, but it would be nice to have the Ubuntu packages built for the Pi.
    Bit of the back story on the project page explaining why the Pi didn't have Ubuntu from the start.

    Some computers much more expensive than the PI do not have a Hardware RNG built in. Both my intel desktop and my laptop don't have a hardware RNG. If you try to generate a key, these computers will stop while gathering entropy. But not any more. I use my pi to dump random numbers into the entropy pools for all my computers that don't have an RNG.

    There are other hardware RNGs available, but none as inexpensive as a PI. Also because the PI has an RJ45 connection, it can be plugged into my router where it can serve random numbers for all computers on my lan.

    Remote wifi temperature sensor. I have an existing 1-wire temp sensor net & wanted to put something in the greenhouse w/o running a wire. I just needed to add a cheap wifi dongle and it just worked. I took a small $ risk and almost no time. If I was doing 10-20, there are cheaper solutions for more time spent, but I think I got a good value.

    Since then, I played with RiscOS on it. I'm now playing with it as a thin client that someone built. I'm also going to play with Plex on it. Maybe I'll play with Plan 9 on it.

    The first task could probably be done on on any of the other ARM boards that run Linux. The others tasks might work on other boards, but people are building and optimizing for the RPi.

    All these ARM and microcontroller boards are fantastic. RPi made the others hit the under $40 price point. It reminds me of the days of Apple vs C64 vs Atari vs IBM and I hope they stick around.
