I still havent learned how to do much more than just blinking led's. So i desided to blink them really fast. Acualy im trying to make one of them devices where you wave it and you see words. I am doing so using 7 bright LED's in a straight line. So i drew out the word Hello on graf paper using 7x5 squars for each letter, then i went in and rought a high and low comand for every time i needed each light to blink for 1ms and looped it to keep going.·this works sort of only becuas i know what its suposed to say but realy its just a blear. Im just wondering how one might go abut this (i wish it were as esay as an LCD).

There was an article in the june 2005 issue of Nuts and Volts on this very thing. I don't think they used a stamp though. The fact that you got anything means you're on the right track, keep at it. Two things, the speed at which you swipe (it's not really a wave) and the starting point make a difference.
