I have a question about dtr module and survival laser.

Hello,
I will buy PL520 50mW module that is soldered driver at DTR shop, and Bargain No diode host bundle in Survival Laser.

Now, Just wondering the module will fit that host?
even driver soldered in module?

And if it will be fine, What should i select driver current option? just blank battery contact board?

If it cannot fit, i will make Laser with PL520, Atoids tin, and etc. Should i put heatsink into there?

Best practice is to always use a constant current driver, you can get those from DTR too. What current? If you buy the driver from him, he can set it for you. You can find the data sheet for that diode on his web page and see what current it is designed to operate at

It will fit. Get the drilled pill option and blank battery board. Also, use a button top battery or add a spring to the contact board positive center If you only have flat top cells.

Use some kind of heat sink inside the can.

Hi Bak,
Yes it will fit the heat sink here are a few pics for you.. This sink is of the extended version of SL.

Re: I have a question about dtr module and survival laser.

The Altoid can lasers are interesting, but I prefer putting everything inside a pointer, as Lifetime17 just showed can be done for a pointer heat sink.
