Hey ambiate,<p>I think you were one of the first few hundred USB NerdKit customers, before we added the 2N7000 MOSFETs to the mix.  Those would probably make your life easier in terms of controlling a bunch of of LEDs at once just for pure power handling reasons.  (Won't dive into this here -- ask on our forums for more info.)  If you haven't logged in to our site recently, then be aware that we have lots of customers playing with IR at the moment, for example:<p>a custom IR TX/RX remote control (two separate microcontrollers) plus accelerometer at <a href="http://www.nerdkits.com/forum/thread/458/" rel="nofollow">http://www.nerdkits.com/forum/thread/458/</a><p>a intervalometer, sending commands to a Nikon or Canon camera via IR remote protocol at <a href="http://www.nerdkits.com/forum/thread/338/" rel="nofollow">http://www.nerdkits.com/forum/thread/338/</a><p>as well as lots of customers getting into our recently-released LED Array Kit and controlling lots of LEDs (although where individual control is favored over total brightness).<p>Mike (co-founder, NerdKits)
