I&#8217;ve been busy!<\/p>\n<p>I received my long-awaited <a href=\"http:\/\/www.raspberrypi.org\/\">Raspberry Pi<\/a> (Pi) Model B. As I <a title=\"Raspberry Pi\" href=\"http:\/\/www.graygoo.net\/blog\/2012\/01\/raspberry-pi\/\">mentioned previously<\/a>, this is a steal for such a compact and capable little computer. I just got around to powering it up, loading <a href=\"http:\/\/www.debian.org\/ports\/arm\/\">Debian Linux<\/a> onto an SD card, and trying to boot, which promptly resulted in a kernel panic. The curse of the early adopter. Fortunately, there&#8217;s a<a href=\"http:\/\/elinux.org\/RaspberryPiBoard\"> support group for us<\/a>.<\/p>\n<p>Initial observations:<\/p>\n<ul>\n<li>The Pi has some nice, modern interfaces, including HDMI, USB, Ethernet.<\/li>\n<li>There is a general purpose I\/O header for hacking.<\/li>\n<li>Backward compatibility is nonexistent, for concerns of both cost and space. No VGA or RS-232 here. I approve.<\/li>\n<li>They\u00a0<em>really \u00a0<\/em>squeezed the part count to save money. In addition to dropping the legacy interfaces, they dropped things like a real-time clock and a\u00a0<em>power switch<\/em>. Again, this is understandable when you have a $25 budget, but<em>\u00a0<\/em>my Pi will have a power switch.<\/li>\n<li>One notable omission is WiFi. WiFi support would have to be added via a USB dongle or other means. My concern here is sourcing adequate current through the \u00a0Pi. My guess is that one would need to use a powered USB hub with a separate power supply. I expect to see a WiFi add-on card for the Pi shortly to address this need.<\/li>\n<li>No mounting holes. There is about 1mm of PCB along the long edges to rest or grip onto to mount it in a case, which I would recommend.<\/li>\n<li>The connector layout is a little odd. The USB jack and SD card slot (with card mounted) stick out. I&#8217;d like to see the USB jack flush with the Ethernet jack. The SD card slot is pointed the right way for easy access, but the wrong way for semi-permanent mounting (like with an OS boot partition). Also, a second SD card slot would be nice.<\/li>\n<\/ul>\n<p><object width=\"288\" height=\"192\" classid=\"clsid:d27cdb6e-ae6d-11cf-96b8-444553540000\" codebase=\"http:\/\/download.macromedia.com\/pub\/shockwave\/cabs\/flash\/swflash.cab#version=6,0,40,0\"><param name=\"src\" value=\"https:\/\/picasaweb.google.com\/s\/c\/bin\/slideshow.swf\" \/><param name=\"flashvars\" value=\"host=picasaweb.google.com&amp;captions=1&amp;hl=en_US&amp;feat=flashalbum&amp;RGB=0x000000&amp;feed=https%3A%2F%2Fpicasaweb.google.com%2Fdata%2Ffeed%2Fapi%2Fuser%2F100121051792258866324%2Falbumid%2F5757333457108003441%3Falt%3Drss%26kind%3Dphoto%26hl%3Den_US\" \/><param name=\"pluginspage\" value=\"http:\/\/www.macromedia.com\/go\/getflashplayer\" \/><embed width=\"288\" height=\"192\" type=\"application\/x-shockwave-flash\" src=\"https:\/\/picasaweb.google.com\/s\/c\/bin\/slideshow.swf\" flashvars=\"host=picasaweb.google.com&amp;captions=1&amp;hl=en_US&amp;feat=flashalbum&amp;RGB=0x000000&amp;feed=https%3A%2F%2Fpicasaweb.google.com%2Fdata%2Ffeed%2Fapi%2Fuser%2F100121051792258866324%2Falbumid%2F5757333457108003441%3Falt%3Drss%26kind%3Dphoto%26hl%3Den_US\" pluginspage=\"http:\/\/www.macromedia.com\/go\/getflashplayer\" \/><\/object><\/p>\n<div><span style=\"font-size: medium;\"><span style=\"line-height: 24px;\">All in all, a good deal.
