I just got my starter kit today, and finished soldering the proto-board a few hours ago. :-) For what it's worth, everything worked perfectly straight out of the box, even on 64 bit Vista :-)
Did I miss a memo? There are tutorials?! Or are you talking about the lessons here?
There's no reason you have to write the tutorials yourself, you know. There's plenty of geeks around dying to show off their knowledge! Define a standard tutorial/lesson format, announce a contest for best lesson, and give a lucky winner a free lilypad or some such. Heck, you'd probably get a lot of submissions with no prize at all :-) It'd still probably cost you 20 hours to manage it, but you might get several lessons out of it. :-)
Or another, less time consuming tack could be forum-based challenges... "Make your arduino do *this*" with an associated forum for people to post how they did it, discuss methods, whatever.
Or have people try to solve the problems on http://projecteuler.net/
using their arduino. I confess I'm tempted to try that myself :-)
I appreciate the lessons on your page though -- It's the clearest, most thorough, and easiest introduction to the arduino that I've found.
And to whoever mentioned the light dependent resistor included with no suggestions on how to use it...
Throw it in series with a resistor and read values in between the two (like a voltage divider basically). Now you have an ambient light meter. Throw the LDR inside a straw wrapped in electrical tape. Now you've got a directional light meter. Use the serial port to periodically record light levels. Use ambient light to control whether some other light source is on. Solve the flickering issue. Put colored filters in front of it and detect certain wavelengths. Get another arduino and allow them to talk wirelessly via LEDs and LDRs. The only limit here is your imagination. :-)
