Its just like the green pointers they sell but red...

Be sure to write a review for it once oyu get it.

I just want to see what lens and module the laser uses. This may be a great host for different diodes if the lens isn't coated and has a better focal length, making the beam diameter slimmer.

plus it runs on 3 volts what driver does it use.

NewWish Also sells a 200mW version of this

Good point!! Must be a boost driver. Or some sort of really really really low drop out driver, but don't the red diodes take about 3.5v? Now I'm even more curious.

There are those tiny tiny red diodes out there that only take 3v to run, and thats with the driver and everything, but I really doubt they have one of those that can do 100mW...

Or does it really have a driver?

I laughed pretty hard at that. I can't wait for someone to buy some and rip them apart =)

Haha ;D

exactly... could be another pulsar

Yea, it's a red diode, doesn't have to have a driver Maybe a resistor+capacitor, or even nothing :-/

 

[styropyro]

My guess is that it is another pulsar type design. Even if it is it is a much better deal than WL's ripoff.

Does the pulsar not have a driver?

IIRC it does, but it's not voltage regulated so anything above 3 volts kills it.

 

[styropyro]

It doesn't have a driver, all that is there on the PCB is a switch. The Internal Resistance of AAAs must be high enough to not allow too much current to go through the diode, if you ran the pulsar off of 2 AAs the thing would fry near instantly.

Or 1.7V lithium AAAs.
