Behold the fearsome predator! (750mW total@650nm)

Would this be classed as IIIB or IV? :-?

So, can you devise a way to converge the beams at a few feet?  Man what a cool bug zapper that would be! ;D

I would say class 4, as the source is over 500mW, mainly when burnng through an external optic. With or without additional optics, i'd still treat it with the respect one would give anything at a half watt +

Well, if you want a burner only, you'd have to insert the modules at a bit of an angle so the beams converge at some point in front of the flashlight.. and then adjust each module for that distance.

I'm sure it'll be delicate work but could be done.
 
Re: Behold the fearsome predator! (750mW total@650

An elegant way to converge the beams for any distance, would be to attach a small toothed gear to the back of the diodes and mate all the toothed gears onto one worm gear inside the housing.

Then you set the worm gear so it can be rotated from a thumb wheel on the housing.
-thumb the wheel forward, and the diodes converge, thumb the wheel back and the diodes separate.

Get real ambitious, and set the worm gear to a motor, tied to a photodiode mounted in the center of the three lasers so it's directly in line with the dot reflecting off of whatever you're aiming at. It can be set so the photodiode activates the motor controlling the wormgear, until the photodiode "sees" the brightest spot of light reflecting from the target (which would be when all three beams have best converged on the target). -An autofeedback system like this is actually much simpler to setup than you'd think.

-just my $.02

-Nice work btw.

Wow, that looks freaking awesome!!!! :o great build! The beams must looks terrific!

Its a pretty large host, takes a long time before it gets too hot., though I'll try more than 10 minutes to see how that goes.

Does the battery last that long? ;)
 
Re: Behold the fearsome predator! (750mW total@650

Does well ;) Say 2000maH for the battery, then thats about an hour run time.
