Weapons Grade Nuclear Trigger plans needed

April Fool http://www.sysopt.com/forum/smile.gif , seriously, I gotta project in the works using some Hewlett Packard IR leds. They are 375mw at 500ma max@2.15v, pulse width 100us, 20% duty cycle@85C. Pusle width tpw 0.01-1.1ms. The graphs of course vary to voltage and time vs amps, the figures given are absolute Max. My prob is I don't know how to achieve a duty cycle short enough to keep the leds cool. I want to fire about thirty to fifty for long distance night vision illumination. I tried to find true discreet filters to use on a spotlight but they are more expensive than I hope this project will be.. any suggestion as to where to stick the IR emitters will be appreciated.. btw, one of my fav sources is Allied Electronics www.allied.avnet.com (http://www.allied.avnet.com) phone no 800-433-5700 . thanx Drvette

So let me get this right you want the LED's fireing at 20% duty cycle with a maximum pulse of about 1ms.

Could you just set up a mark space generator driveing a fet to power the LED's?

After posting to this thread I will add my name to the list of new files the FBI has. I didn't want you to feel alone in this. http://www.sysopt.com/forum/smile.gif http://www.sysopt.com/forum/wink.gif

LOL @ Dave, aggh, I just hope the Federal Bureau of Instigation isn't interested in Apr 1 jokes.. BTW, I still have the post from some nut in Australia who said that he would blow up W'shton with a nukie bomb.. How stupid, he thinks the boys don't have contacts in AussieLand. He's a beggin for a breakin" as we saw down here.. I'm still astonished someone would do that.. Did anyone else check his e-mail address ? It was somthing like f*** you.com or so. Yet another future "Darwin Award Contestant" http://www.sysopt.com/forum/smile.gifDrVette PS, me and konan the barbarian are doing the e-mail thing to save bandwidth, if anyone cares about what's up with the project, e-me or post..
