Even if you don&#8217;t fly your own balloon you can have a lot of fun helping other people by tracking their flights.  All you need is a suitable radio aerial and receiver, and you can find out all about how to do this on the <a href=\"www.ukhas.org.uk\">UKHAS wiki<a> which is a triumph of content over organisation, but the first link you need is to the <a href=\"http:\/\/ukhas.org.uk\/guides:tracking_guide\">Tracking Guide<a>.  You don&#8217;t even need an expensive receiver, as a simple SDR (aka TV USB Dongle) will do as explained <a href=\"http:\/\/ukhas.org.uk\/guides:sdr_tracker\">here<a\/>.  To get the best range (so you can receive flights across the UK) you need to get an aerial (cheap or make one yourself) up high, and preferably add a <a href=\"http:\/\/ava.upuaut.net\/store\/index.php?route=product\/product&#038;product_id=83\">HAB Amp<\/a> specially designed for the task.<\/p>\n<p>The HAB (High Altitude Ballooning) community is small but very friendly and active, and almost everyone in it hangs out in the #highaltitude IRC channel.  To ask questions, or see what we&#8217;re all talking about, use an IRC client (I use <a href=\"http:\/\/hexchat.github.io\/\">Hex-Chat<\/a>) or connect via the <a href=\"http:\/\/webchat.freenode.net\/?channels=highaltitude\">web client<\/a>.   I&#8217;m on there as &#8220;daveake&#8221; but you&#8217;ll find plenty of other friendly people there too.<\/p>\n<p>Finally, flights are (usually) announced on the <a href=\"https:\/\/groups.google.com\/forum\/#!forum\/ukhas\">mailing list<\/a> first, telling you when the launch is planned to be (weather and technical issues often have a say in that), what frequency etc.  To track a flight, join the list first and when you see a flight you want to track, join the <a href=\"href=\"http:\/\/webchat.freenode.net\/?channels=highaltitude\">IRC channel<\/a> and check that it&#8217;s still going ahead.  People there will be pleased to help if you have any trouble setting up.  Even if you don&#8217;t help track, you can watch the action on the <a href=\"http:\/\/spacenear.us\/tracker\/\">map<\/a> and that will usually have links to any extras such as live images or video streaming from the launch site.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Last night I went into London to meet up with other Pi enthusiasts over a pint, and to do a talk about my Pi-based weather balloon activities.
