Raspberry Pi Hits the 2 Million Mark 246

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?)

        TI fully documents their system on chip (SOC) chips.
        Broadcom doesn't.

        This alone makes Broadcom (which is in the Raspberry Pi) completely non-free and craptastic, and the BeagleBone worthy of consideration by a hacker.

        F Broadcom. F Raspberry Pi. Don't waste your time on non-free systems which you have to reverse engineer because the documentation is purposely incomplete.

        The fact that there are significant reverse-engineering efforts going on
        is proof that the Broadcom chip in the Raspberry Pi is anything but open.

          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.

      Many people won't care what the CPU is. I thought about getting one and I know I don't care. It's cheap and flexible, has decent enough interfaces, has a huge community, and many people who will be coding on it will be writing Python anyway. I had a problem in mind and needed a small programmable device to solve it. I think many people will approach the pi this way rather than from a spec sheet perspective. I.e. "what can I do with this" vs. "what's it made from".

      It is not about the power! You have a cheap ass device that has a massive community that have solved almost all the bugs in the thing so any problem you have is a google search away. The foundation pays for ports of software to it. When you buy a new peripheral you can find quickly if it works with the pi and how to make it work. You can find lots of different enclosures and almost any other wacky thing you can think about.

      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.

      My lowly workhorse Pi with its ARM 6 processor performs admirably as a:

      - DHCP server
      - Authentication server (Kerberos, OpenLDAP server and phpLDAPadmin) and publication service for network assets (OpenLDAP again)
      - Mail server (Dovecot, Postfix, Squirrelmail, Spamassassin, ClamAV, Amavis)
      - HTML image gallery
      - Home wiki (MediaWiki)

      Performance is no issue with any of this. MediaWiki is the slowest, but most pages load in 1-2 seconds. We're a busy, high-tech household so it serves up to seven laptops, five destops and nine mobile devices, many of which dual boot. Device management was a nightmare before the Pi saved the day.

      • The biggest issue I have with DLNA is that it wildly depends on the receiving device.
        Streaming through the PS3 allows for high quality content, while streaming directly from my DLNA enabled TV caused the signal to be strongly degraded, I guess because the TV doesn't have enough horsepower to handle the larger stream.

        In any case, good riddance.

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.
