ok, ive ordered a 20x off theMonk :)

and the host i wanted is out of stock, they only discovered after i'd payed :p
ill use this one instead: http: //www .dealextreme. com/details.dx/sku.3405


does anyone know a driver compatible with this build that i can order and recieve asap? my assignments due in a little over 2 weeks :s
You could do this:

Order 2 batteries from here:

http://www.batteryjunction.com/10440.html

Get a AAA dummy battery from a member on the forum, and use a groove driver:

http://hacylon.case.edu/ebay/laser_diode/LavaDrive1.php

Then PM Drlava and tell him to preset the current to 420mA.

Or:

Buy a rckstr driver

Buy 3x3.7V AAA from link above.

Remember, the 3.7V cells are about 4.2 volts fully charged, and the Rckstr driver takes up to 12 volts.
So to be sure, ask him to remove the MOSFET protection (this way, it will take up to 16 volts).

And don't forget to ask him to preset the current to 420mA ;)

Or:

Wait and be able to use primaries ;)

BTW, batteryjunction is located in USA, so no slow China shipping.

I found another method!!!

http://www.dealextreme.com/details.dx/sku.4171

Use this host! It takes 2 CR123A batteries that you could buy at your nearest home store (walgreens, safeway, fred meyer, etc.)
The rckstr driver needs 5V for reds, so you can use 2 of these, they are CR123A size:

http://www.batteryjunction.com/uf16340.html

Then you don't need to remove MOSFET protection :D
And you can use the Rckstr driver happily :D

And the great thing is, jayrob makes heatsink for this host, and has a full tutorial on this host :)

Your welcome :)

[highlight]Edit: It says you can't use 3.6V batteries. IGNORE THAT, THIS GOES FOR THE LED. If you turn it into a laser with a driver, everything will be fine.[/highlight]

hey guys!

got another bunch of questions :)


am i correct in thinking that 'duty cycle' is the period of time the laser can be safely used without overheating?
if not, what is it?

also, is there an explaination of exactly how rkcstr's driver works? like, in detail.
driver page: http://www.laserpointerforums.com/forums/YaBB.pl?num=1206339013

and ill most likely have moar later ;D
Correct, that's a duty cycle.
The page on which he sells them is the most information you will find...
