I am working on building Roy's 7 color pocket laser with spiro and wanted anyone else who is to post pictures and their progress. I also will need help along the way because I am very new to lasers. ALSO I will not post pics till i get a camera, got complaints about iphone pics.
Progress: I have a PHR sled sawed down to only the essentials. I also have a plexiglass cover made for it so i can seal it up when I'm done.
I made all three adapters for red blue and green.
Lasers I'm putting in it:8x Blu-ray diode(probably 250mA~300mA) LPC red diode(400mA) and o-like 80~100 module(preinstalled driver). I will be powering red and blu-ray with DDL drivers. They will all be using larryDFW's high power lens' to try and get similar beam except for green, I am having trouble modding my o-like green to use glass lens. I will just leave the glass lens mod for another project.
My build will be a little bit different, I will need some heatsinks so i think Im going to seperate my batteries and lasers in a separate enclosures with a plug so i can split the two parts and transport easily.
(*SOLVED SEE BELOW*) I am also wanted to add adjustabilty to the laser's power because I'm using such powerful diodes. I need input on how i can do this, I dont want to just put a pot on my DDL driver because then i would be able to turn the power up too high on my drivers. Could i put a pot between the DDL drivers and battery so that i can adjust the power without going beyond the current set by my DDL drivers? Also where do i add a pot on the green module so i can adjust it (I know I am not supposed to mess with the pot on the driver that came with it). I would assume just put a pot between battery and driver. If I can just add pots between the drivers and batteries what ohm pots should i use?
Other Questions: What focus should my lasers be at? Should they be focused to infinity or should the be focused closer to allow for more light to be transferred through the optics.
What kind of transmission/reflection should I be getting through the optics? Should it be like 90%-80%-70%... so on. I know this depends on individual factors I'm just wanting a ballpark range of what others have gotten.
Batteries: I was thinking of using three 4.2v 2500mAh 18650 batteries (tell me if this will work). Can i wire all the batteries up in parallel and attach the green driver at one battery(4.2v), the red driver at the two battery point(8.4v) and attach the blu-ray at the end of the parallel wiring(12.6v)?
