Following my Arduino article for Custom PC, I was asked to give a 20/20 presentation – twenty slides, each one of which lasts an enforced twenty seconds – on the subject for GeekUp Leeds, a monthly gathering of local techies, hackers, and tinkerers.

The presentation took place at the Lounge Bar in Leeds on the 15th of September 2010, to a pretty packed house.

The slides from the talk can be downloaded in PDF format.  They’re released under a Creative Commons – Attribution – Sharealike – Non-Commercial licence, meaning that anyone is free to download, use, remix, or otherwise modify the presentation so long as it’s not used for commercial purposes and I’m properly attributed as the original creator.

If in doubt, my name plus a link to this site is enough.
