I am waiting for my first Diy build's parts to arive from China but i would like some info on drivers, info on the diode and info on the and what Ma to use, my torch will only fit 2 aa batteries.

also feel free to give me some tips :)

Thank you!!
 





 
 
Thank you for the reply, im using a few peices of aluminium which i will drill a hole into to place my module and for the part of the heatsink that makes contact with the module i will be using copper since copper draws heat away quicker

If you have any information on making heatsinks, tips , how much mw will 410ma or 440ma produce and anything of the sort please feel free to help :)

Look for the graph for mW/mA at this site, Red laser - Laser Wiki

But you should try it first at max 300mA to make sure everything works. Then push it beyond 400mA if you dare.
 
ty will check it out

Btw any idea on where to get meridith lens?

also whose drivers are better? lava's or rckstr's for a red laser

Not sure but I would just use the AixiZ lens.

IMO neither one is better than the other. The difference is rckstr's driver is a linear driver. Drlava also produces a linear driver (groove2) but his other drivers (flexdrive and boost drive) are buck/boost and boost drivers respectively. Another difference is the price, rckstr is a lot cheaper.

With the host you chose I would just use the rckstr driver with two Li Ion batteries (size 14500).

OR, if you want to use regular primary AA batteries then use a flexdrive.
 
any idea on where to buy drivers from?

if i have to i will use surefire batteries $5.37 - TrustFire Protected 3.7V 900mAh 14500 Lithium Battery (2-Pack) - Batteries

also is it worth buying glass AR lens and if so where can i get it from for cheap?

If someone can give me a list of parts to make a tiny driver that will fit into my host 3W LED super bright Flashlight outdoor waterproof 5026 (eBay item 170518206367 end time 19-Feb-11 20:42:22 AEDST) : Sport

and a tutorial i would probably make my own.

Thanks!! :)

The sled is somehow expensive uh? You can get the diode himself (extracted) from rayfoss for 18$ and may ask Faona a discount. I get mine there :)

You can get the AR lens from rayfoss too.. or Aixiz if you want fast shipping and live on USA.
I've never seen that flashlight before, dude. Probably you're going to use a single battery, you can use a resistor to limit current. Many did that before and it work out well.
If the flashlight only fits TWO batteries, you can use Rckstr, but it will waste the not used energy in heat. I recommend buying a spacer (a thing that looks like an AA but is only a conducting body, in case you don't know) and using the resistor then. You need to calculate what resistor to use, tho. Some said 6ohm 1/4W work very well for 10440, so 10ohm I think you're fine.. study ohms law-- you will love it :P
 
if i use a rckstr driver would it be better to use 2 normal energizer AA batteries (what my torch fits) or two ultrafire 3.7v batteries? $5.37 - TrustFire Protected 3.7V 900mAh 14500 Lithium Battery (2-Pack) - Batteries
 
Dude.. you are going to use 2*AA li-ions on that flashlight, right?
Thats 8.4v charged, 7.2v nominal and 6.4v discharged. The diode only needs 2.5v so, you will be turning extra voltage into heat. That isn't good as 5.9v + current would be turned into heat.. I don't know if the heat generated would be the current draw of the diode, if thats the case, the average heat generate @ 300mA output, would be 1.7W... nasty.

I recommend you should use a single 4.2 li ion, a spacer (to fill out the empty area) and a resistor to limit current. Even without the resistor your diode should work.. for a very little lifetime, thats why you should use a resistor.

IF you want a driver.. You should get a flexdrive and TWO common AA.. IMO...


edit: answer to your second post:
Dude, the Rckstr need 1.5v extra voltage so
2.5v (diode voltage) + 1.5 = 4v. So as two AA gives out 3v they won't work. A single 14500 will work like a charm (charged) and two will generate MUCH heat.


oh btw.. please write everything in a single post. Don't post many things like I do :)

w8 do u mean for me not to post replys? when you quote "oh btw.. please write everything in a single post. Don't post many things like I do" ??? lol
btw what is MAH for example the ultrafire 14500 batteries are wuoted to be 900mah


Lol ok


problem is people probably wont notice the post that much, well i dont really know thats just what i think

Oh well, some diodes have a little variation BTW. Yours may be 2.5v but some are as high as 3.3v.. thats needs two 4.2v cells...
You have already bought the Rckstr driver? If you did, you be sure to heatsink it well..
if you have not, use a resistor to limit current as I said.. ;)

a spacer (adapter) from AAA to AA can be bought at dealextreme; you will just need to solder a wire from the + to the - of the adapter and you're done.

edit: dude, if you have too much things to say.. write them ONCE and click Post Reply ONCE. If you want to add more things (like you did two times) find your last post, click EDIT and write more.. like I'm doing now ;)
 
I've never personally used any of those drivers. I have seen other members who have though, maybe they can chime in regarding those.

I would still recommend the rckstr for your build with 2x14500 Li Ions. The red diode uses ~3V and the rckstr driver will need ~2.5V so thats 5.5V total. If you use 2X14500 Li Ions completely charged you have 8.4V so that leaves ~2.9V leftover. The driver will dissipate that excess voltage as heat but there are a few things to consider.

The driver CAN handle quite a lot of heat, it was designed to. Secondly, as soon as you power up the laser the total voltage your batteries have to offer will sag. Third, you have to have some overhead voltage to give you some run times. I don't know about you but I don't like charging my batteries after 30min of use.

Last point, be sure to heatsink your diode. In a host like that you might need someone to turn a heatsink for you on a lathe. There a several members on here that have lathes or access to one. If you can't find anyone to make you a heatsink I'd be willing to make one for you but you would have to send me your host so I can fit it nice and tight.
