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...
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...
Re: New Fast Sled GB (inc. LPC-826)
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...
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?
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.
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!
