Hi everyone, I just wanted to share this awesome 650nm build I just finished.

I apologize in advance for the crappy quality of photos. I took them all on an iPod. The nicer ones used an aspherical lens to magnify which helps the quality.















Specs
Power Source: 10440 Li-ion rechargable cell
Driver: Stock LED Driver (This is what makes the build so cheap)
Driver output: I measured 330mA, which takes about 3 seconds to climb to.
Estimated mW: 200+ :eg:

Beamshots!!! :D :D













The beam is pretty bright in person! I can see the beam better than I expected in my room with the lights on.

First of all, I would like to give full credit to LPF Member Rafa for the host idea. This build has been done before, but it isnt a really well known host it seems. :thanks:

The host I used was a $2.50 DX Keychain light

Mini LED Keychain Flashlight (1*AAA) - Free Shipping - DealExtreme

The host came with some strange leopard pattern, different than as advertised. I hate that look so I just covered it with some electrical tape while I find some spray paint or something.

All I had to do was remove the lens, reflector, and LED which took me a grand total of 5 minutes. The Aixiz module is just a little too small in diameter to fill it well. I just used some aluminum foil and thermal adhesive to secure the laser in place.

The host is case negative, so wiring it up is easy. The driver itself is very tiny. It may even be worth buying the host to use the cheap driver in other DIY projects!

All I did was solder a wire onto the driver output and connect it to the LPC's positive pin. There's enough room between the driver and laser housing to bend the wire if you do it right, which is not hard.

The total cost for this build was $15.50 excluding shipping, which is very negligable

Diode: LPC-826 from Modwerx ~ $11
Module: Aixiz Housing ~ $3
Flashlight: Keychain from Deal Extreme ~ $2.50

I don't know how long it runs, but it seems to have lasted me 30 minutes of use so far and the battery is still at a good 3.7V!

Anyway, Thanks to Rafa for suggesting the host! I very highly recommend this as an easy 650nm build and/or intro build for lasers.

*EDIT*
The only downside of this host, other than the heatsinking, is the switch. Its fallen apart twice since I've owned the host (which was about 2 weeks prior to the build). Its an easy fix though as it just a small pushbutton and a spring pressed against it in the tail-cap.

Good job, soon you will be the new wanaburn.

Im still trying to find time to start my build, ive got everything for the host, now i need some really evil stuff to put inside it.
It will be hideous, on purpose :whistle:

Go for it! Just remember, the stock driver will only drive a red diode. You could salvage the driver for a later build and then replace it with one of Dr. Lava's drivers I believe :)

Re: $16 DIY 200mW 650nm [Pic Heavy]

Glad u have this linked :yh:
I definitely think I'm going to try this build.
I've been intending to build a blue laser, but I just hit a big snag, but whn I saw this I was just like cheap powerful laser in a cool host! :drool: must build.
Glad you had this here for me to find. +1 rep :yh:

Go for it! If you have any questions during it feel free to ask. I'm going to try to post an in depth tutorial when my next one comes in.

2~5mW Dot Laser Module (3V) - Free Shipping - DealExtreme
that's a link to it I would encourage you to read a LOT before doing your first laser build. I lurked for a solid month until i understood about the driver component, diodes ,tem modes, thermal runoff. 16$ is cheap to jump into though and will teach some good lessons.
Also me not harping because your new but all you had to do was search dealextreme for aixiz module they are pretty universal you can even get different lenses but they are too expensive IMO for this laser.

yeah i saw that.... but i cant find the $3 Aixiz Housing Module, thats why i asked for a link...
I bought my aixiz housing from Modwerx. So I suggest buying the housing and the diode in one purchase to save on shipping.
I'm not from Australia so I can't say for sure. But I'm almost positive that customs can't confiscate parts.

I agree with the post above, do research before this build. Be prepared.

*EDIT*

You can get the housing here http://www.modwerx.com/shop/index.php?main_page=product_info&cPath=12&products_id=11&zenid=5m2s6l1hombbfgjjoj7di3h8t0

The diode is available on the same site.
