		<description><![CDATA[There is supposedly an Afrikaans expression that translates as &#8220;flipping a coil&#8221; or &#8220;flipping the cone&#8221;, etc. Kind of a more evocative equivalent to &#8220;shitting a brick&#8221;. It refers to the act of turning one&#8217;s underwear inside-out to dump out the results of having shit one&#8217;s pants, e.g. due to extreme rage or surprise. The [...]]]></description>

		<description><![CDATA[So, a friend of a friend recently managed to buy the original Rez, complete with new-in-box Trance Vibrator. But the peripheral didn&#8217;t work &#8211; it would be detected, but otherwise not do anything. Knowing I had produced a compatible open source version of this hardware, she brought it over for a look. The motor was [...]]]></description>

So here is a scheme to give outdoor direct-seeding a little head start. Seeds for many food plants, such as melons and peppers, [...]]]></description>

		<description><![CDATA[We shuddered when it was announced that MakerBot were taking the next version of their RepRap-based printer design closed-source. We crossed our fingers when the CEO responded to the flap saying they&#8217;d be &#8220;as open as possible&#8220;. We watched with popcorn the various flaps about Thingiverse, legal mumbojumbo, attribution and moral rights. But now this. [...]]]></description>

		<description><![CDATA[Woo, it&#8217;s been a long time since I messed with pick &#038; place stuff. Bad Tim. An irritation I have been having is making everything work using reliably sourceable, off-the-shelf parts (not lucky eBay/surplus finds). In particular I&#8217;ve found small &#8220;tin can&#8221; stepper motors are hard to source in small quantities repeatably, and once you [...]]]></description>

		<description><![CDATA[So, last week I joined the bandwagon of exploring software-defined radio (SDR) via one of those super-cheap Chinese TV tuner USB sticks. In a nutshell, the idea of SDR is that, rather than the traditional approach of building dedicated radio receiver hardware for each possible RF band and modulation type (here&#8217;s your AM radio, here&#8217;s [...]]]></description>

EnergyMicro&#8217;s application note AN0023 has an overall good overview of setting up an Eclipse + GCC (CodeSourcery) toolchain. Nevertheless, in attempting to replicate this process on my Win7 system (work PC; [...]]]></description>

		<description><![CDATA[Problem: Windows, and many Windows apps that use serial (COM) ports, have various problems accessing &#8220;high&#8221; numbered COM ports. I cannot find an authoritative or quantatative definition of &#8220;high&#8221; (and it may depend on your app), but I have seen apps start failing after COM8, COM9, COM15&#8230; anything in the 20s is asking for trouble.
