Lego Mindstorms + Lasers
hamsan writes "My brother just hacked a laser pointer into an NXT light sensor and fully documented the process. From the page — 'Total Project Cost — $16.99 plus shipping. Time Required — Approximately 2 hours of tinkering. Having an Alpha Rex with a Laser — Priceless!' Of course, the usual warnings about voiding warranties and avoiding lasers apply."
How do you explain to a small child not to stare into a laser beam? The little guy in one of the last pictures obviously couldn't read or understand that safety label.
Not to sound like a naysayer, but honestly the laser adds almost no functionality whatsoever to the Mindstorms kit. In a course I am taking we are designing and building ten different kinds of robots out of these kits, and there isn't one that would benefit from having a frickin laser beam on its forehead.
1. Build something extremely nerd-friendly out of items found at Amazon.com 2. Create website explaining how to do it (complete with amazon referal links) 3. Submit website to Slashdot 4. ??? 5. Profit!
