Thanks for the quick replies! I thought that tutorial was a little sketchy (speaker wire?!).
I'm not married to 9v, my original concerns were space & weight. The frame I have is a little shallow, so AAA's might be a better choice. Weight isn't a concern anymore, because I found these awesome super-strong velcro mounting strips yesterday.
The LEDs I have are marked "1.3-1.6", should I adjust my calculations? I want to get the right resistors, and since I have to get a AAA holder now... (I always seem 1 component away from a completed project
As long as I stick to the parallel plan, this shouldn't get hot, right? I wanted to try a new mounting idea I saw http://hackaday.com/2012/03/06/interesting-substrate-used-to-position-leds-of-this-word-clock/
Now I'm chickening out and thinking about going with perfboard...
Whelp, looks like no bread-boarding today, unless I go to RatShack.
