how to assemble all parts?

[CT915]

hey,

i'm a dutch guy, so my english may be sometimes very bad, my apologies for that.
but i think all of you will understand me.
i had a question about building a laser, and putting all parts together.
the parts i'm gonna use are:
- a lpc-815 diode
- an Aixiz housing
- this driver: (from someone on this forum) Surface Mount FULL RANGE ADJUSTABLE Laser Driver pre-assembled [Stonetek_RKCSTR_FULL_RANGE] - $18.99 : StoneTek Electronics, Your Laser Parts Store
- 3.7V 900mAh Rechargeable Lithium Batteries

i thought this was enough for the laser. But when i've put the diode in the housing, and the driver in the back-end of the housing, how do i connect the housing correctly with the batteries?
can i use a flashlight for it? or do i have to connect it otherwise? i'm sorry, but i've never done this before.. i'm sorry that i'm such a noob XD

thanks,

Bas..

Your going to need a heatsink also. I' will let those who know pointers better than I continue this discussion....

ok, thanks, does anyone know where i can find a heatsink for a reasonable price? why do i need also a heatsink actually? cause i thought that wasn't necessary? (i'm really a noob, sorry for that :$)

Hmm...I can't explain logistics, but I can say that a heatsink is very important on some of the more powerful lasers, it's what takes the heat from the laser diode because without it the diode will/would overheat and die. It's also needed if you don't want quick 'duty cycles'. Without it you'd need short duty cycles, 20sec on 40sec off, etc. Also, yes, you can use a flashlight, but I recommend you look at some of Jayrobs kits, he is a very professional individual, and will be able to assist in your build. What he can do for you:

Make you a kit
Set up a flexdrive(a flexdrive driver is your best bet when using a kit, it's smaller)
set-up everything for you so all you need to do is put it together.

Since you alreay bought the rckstr driver, I recomend you do the '3405 flashlight build' I will link you to it in a minute. For the time being, I'm going to 'butter you up a bit' so to speak. This build will cost an additional $55 (if you get the lead wires soldered on, so it'll be (LITEREALLY) a 5minute set-up once you get it in the mail). All you do (once you get the kit) is unscrew the cap, solder the driver to the lead wires in the kit, slide the module into the heatsink, screw in the set-screw, put in 3 rechargable 10440 batteries, and you're off! You will need 3 10440 batteries and a charger. I already have this kit (just bought it). And its amazing, it feels solid, no rattling, clicky switch on and off for safety and for additional awesomeness, it's a great host/kit combo! And, the links you've been waiting for! (PS: you won't need a flexdrive for this, but plan on getting one for other kits)

Tell him Bloompyle sent you

PS: you need 10440 batteries!

B4x 10440 batteries PLUS charger combo pack!

Tell him I sent you, and that you're from LPF, you'll get s lil sumthin sumthin

Also, if you need more help building, there are a TON of people here, 100 times better than I that are more than willing to help you. So feel free to ask, just make sure to also use the search button, it's a life saver!

Hey CT915,

You will need two of those batteries to achieve any decent power for your build. You probably knew that already but just for info.

A heatsink can be found on this site in the, "Buy, Sell, Trade", or "Proshop", sections. There are plenty available. You can also find a decent host in those sections as well. Again, there are plenty on offer. I have used Jayrob's hosts before and they are quality pieces of kit but there are others available so have a look there.

The wiring for the module is fairly simple. The positive and negative are labelled on the driver and should be connected to the relevant ends of your battery, (with a suitable switch). It is possible to use the case of any host for one path and it is really up to you which way you choose. It may help your understanding to try connecting without a host at first. This will not look pretty but will get your laser working.

The reason for the heatsink is that these LDs, (laser diodes), we call them LOC diodes, (Long Open Can), produce a fair amount of heat when outputting good mWs. (~400mA should get you above 200mW output. Graphs on these are on the site too so do search for something like, "LOC graphs", or, "Setting drivers"...) This heat is not the friend to our little LDs! It must be got rid of to prevent death. Having said this, a conservative input current and sensible duty cycle should keep your diode from harm until you have the necessary parts to start cranking things up.

I wish your build well, and post some pics when you're done.

I hope that helps. Any other info can be found using the search button but if you get stuck then ask.
