Making a hot-wire polystyrene cutter

We found a load of polystyrene in the garage this afternoon, so we decided to make a [hot-wire cutter](http://en.wikipedia.org/wiki/Hot-wire_foam_cutter) for it. Basically, you take some wire with an ohm or two resistance and pass a few amps of current through it. The wire is held tight and the polystyrene melts as it passes around the wire.

Ubuntu 10.04 on my netbook

I’ve said [before](http://parallelpoints.com/node/12) that I’m using [Jolicloud](http://www.jolicloud.com/) Linux on my netbook. Recently I installed [Quassel-core](http://quassel-irc.org/) on my server, and needed the Quassel client to connect to it. Jolicloud is based on an older Ubuntu (9.10 IIRC) and that meant an older (0.4) Quassel client, which doesn’t connect to my shiny 0.6 server :( So I’ve upgraded to Ubuntu 10.04 Netbook edition. There’s not much difference in everyday usage. Big setup problem though – it doesn’t have the Broadcom drivers for the Wifi installed by default.
