Thanks for the kudos everyone, I have had some experience modifying maglites and building torches but this is my first laser:)
Do you want a picture of the backside of the board with all the components on it (means taking the laser apart)? The pcb is just a disc of prototyping board with no...
Hi Guys
This is my first laser build. It has a BDR-S06J 10x laser diode driven at 400-410ma. It has an AixiZ 405nm, three element glass lens meaning it should output around 500mw.
The host is a 4C Maglite sawn in half :) it offers amazing heatsinking and it is large enough to fit everything...

Hi Glenn
If possible I would like to buy one BDR-S06J sled, 3 aixiz modules and one pair of your laser goggles.
I will require international shipping.
Also is it possible to label the package as under £18 in order to avoid UK customs tax.
Can you pm me with...
If I was you I would just go with the reflector because in order for you to have a semi useable beam with an aspheric it would need to be compleatly out of focus and even then the beam would be full of artifacts. So you should get a lot more throw only using a reflector and a better looking...
Hello swimminsurfer256
I would like to buy one laser pointer + international shipping for $16, can you pm me with your paypal address.
Since I live in the uk, are you able to label the package as <1mw or something similar to avoid customs?
Thanks
As far as I know, for the same power 405nm (violet/blu-ray) is slightly better at burning than 445nm (blue) as it is better absorbed by more materials. Also since blu-ray diodes are single mode they can be focused to a smaller point and the beam will have a lower divergance for burning at...
The prices have not changed, when I went to check the prices I noticed the currency has been changed to Canadian dollars making everything seem more expensive. The prices in US dollars are the same as yesterday.
Never use different batterys in series, especially with Li-ion's as they can easily explode! I would suggest you read some more about Li-ion's as they are dangerous batteries if used incorrectly.
I never thought about that, good idea, but it would make it a bit more complicated and I think the op wants a simple solution.
An even better way is to replace the transistor with an op-amp/comparator as this allows you to reduce the voltage drop to around 0.05v and a small pot can be easily...
You could get away with 7.2v if you used a different linear driver like the one below because it has a lower voltage drop of around 0.55v compared to the 2.5v of the lm317 driver. It is slightly more complicated to build but it can be a lot more efficient.
Power LED's - simplest light with...
I don't own that many lights but I have likely made the furthest throwing, standard size (standard 52mm reflector size) maglite in the world!:eg:
It can light up objects up to 1km away!
