+
+This year I gave a [mini-conf](http://www.annodex.org/events/lca2013_mmm/pmwiki.php/Main/Timetable) workshop at [Linux Conference Australia](http://linux.conf.au). I gave each of the participants a plank of wood and a bunch of cheap parts. By the end of the workshop, I had them all rocking out on their own homebrew slide guitars!

+Here's a video of the build process and a bit of a demo:

+
+Because of the lack of time and tools during the workshop, it was important to keep the complexity down, so I pre-drilled and "milled" the planks.

+
+Here's a list of the parts if you'd like to make one yourself:
+
+- [Guitar pickup](http://www.ebay.com.au/itm/390440570663)
+- T-section bracket
+- eye-screw
+- Electric guitar string
+- 1/4" input plug
+- metal pipe (whatever size fits your finger best)
+
+Tools needed:
+
+- drill with thin drill bit
+- router with flatbet milling bit (or chisel)
+- hacksaw
+- file
+- pencil
+
+Some tips:
+
+- Make sure the string is an electric guitar string. It needs to be made of metal in order for the pickup to work
+- Use a thinner gauge string rather than a thicker one. Thicker gauges cause more tension on the eye-screw.
+- Be careful when tuning or handling the string. The string may slip or snap and get you in the eyes!
+- You'll want to wrap the string in a clock-wise motion, because the screw will tighten in that direction
