630mW 445 Keychain CR2 Jayrob Kit Review/Build Tutorial

[yobresal]

10 months later.......LOL. I actually just ordered one of these kits from Jayrob last night. Not sure if I should go 405nm or 445nm

lol almost as strong as an arctic :na:Great build!

greetings,,

EDIT: just to show how crappy an arctic is lol

 

[flogged]

Beautiful!! I've a weakness for the very small laser pointers, which are nonetheless very powerful. A fun gadget to showoff to friends.

My two favorite light toys below: pocket mini red, and muyshondt aeon flashlight. Both easily pocketable.

what diode did you use DTR? becuase i cant find a mention of the used diode in the thread at all

 

[DTR]

It is a 445 diode.

 

[daawood123]

yes but isnt there a name for it? like m140 etc

 

[DTR]

Yea this is an older build so it was done with an A140 but it does not matter A140/M140/H1600 they will all work in this exact same setup.

 

[mattco2]

the m-140 and h1600 diodes tend to be more efficient

Would you mind posting a complete list of the links needed for buying the parts?
I really want a DIY laser, and this is awesome

boost driver(if you want a good starter host/heatsink go for a c6 shell and matching heatsink) or if there not in stock PM flaminpyro he has the flexdrives but the cost 25$ instead of 10$

The links you posted are broken for some reason.


I would talk to Jayrob before getting a new ben boost for this host. It is a very tight squeeze with a Flexdrive and it may not fit the ben boost. Either way Jay can help you figure it out.

Here are the links to my diodes that seemed broken in the last post.

[benmwv]

I built a 635 in one of these hosts, and I cant tell you its a very tight fit. No way you would get a ben boost in there.

 

[jayrob]

Yeah it's a bit of a tight squeeze even with a FlexDrive as the pictures in my thread show...

But another thing that makes a difference, is to use the RCR2 battery that I have linked there.

There are different length CR2's, and that one is the shortest rechargeable CR2 in the 4.2 volt full charge size that I have found...

 

[mattco2]

yea definitely not a beginners build maybe you should just do a c6 or a guidsmen or a something similar
