This is my version of the yellow pointer project shown by the one and only rog8811.
He always comes up with such cool projects. I pretty much followed his tutorial. Just a different style on the machine work.
And I used different optics...
Two turning mirrors from PHR sleds. And some thin copper wire that I have. Plus another little coated optic from a GGW 6X sled...
Also, I show a 10440 battery mod at the bottom of this post for another option!
Here is the red/green pointer form DX that is used to do the three color yellow mod... It uses 2 X N size batteries. (LR1)
Nice little pointer!
* DX pointer:
DealExtreme: $31.07 2-in-1 Hybrid 5mW Red + 5mW Green Laser (Supports Dual Laser Mode)
* Original tutorial from rog8811: (using dichro's from PS3 sleds)
It can be done - Low cost yellow pointer
Here are the pictures of my modification...
Really a cool project! I like it so much that I had to show it!
Thanks for yet another great project Rog!
Beam shots: (with some smoke)
In this beam shot, the yellow, is a little on the green side. But it is still pretty cool!
This picture was taken without the 'dichroic mirror' used. (shown below)
The yellow is much better now with my new optic installed!
See 'Update' below, and other pictures taken with the dichroic mirror installed! (See below)
One other thing worth mentioning... I noticed that visually, the lasers seem really stable for long on times!
Update: (Add a tiny dichroic mirror for a much better color blend!)
I just discovered a great modification for this build! Using a 'dichroic mirror' from a GGW sled. (thanks for identifying it HIMNL9)
I have a bunch of optics that came from various sleds and was experimenting to see if any would make the combined beam more yellow.
I found the perfect optic. I didn't know what it was until HIMNL9 identified it, but I knew what it does for this mod! It is from a GGW-H20L sled.
Here are the pictures...
I just glued it to the inside of my custom cap... Really cool!
I was thinking about possible reflection....
And I concluded that since the green is already passing through the turning mirror, before it reaches this 'dichroic mirror', there is very little chance of any reflection going to the green module.
Because it would hit the mirror side of the turning mirror, and not pass through much, if at all...
Anyway, as I mentioned, I did not know what the optic was for, only that I could not measure any loss on my meter for red, and only measured a 1mW loss for green. So it seems to be the perfect little 'helper' for giving more 'yellow' on the blend for this mod!
Results!
These pictures are taken with the tiny dichroic mirror from the GGW 6X sled installed in my custom cap as shown above...
Taken in complete darkness. And yes, these are the real colors!
These pictures show how nice the yellow is now!
Power measured with the GGW dicroic mirror installed:
Red - 3.8mW
Green - 2.4mW
Yellow - 6.2mW
SCHWEET!
(Perfect alignment needed for these results)
P.S.
I thought of selling the custom tips (with some copper wire), but when I built this thing, and realized how difficult it is to get those turning mirrors adjusted just right. I figured that most people will give up! And then they would regret buying the custom tip from me. Although the red/green pointer is really a pretty cool unit in itself!
Plus, the tip is a fair amount of work including the cap, so I don't know if anybody would want to pay what I would ask. Probably around $45 bucks.
One thing I do have, is a lot of that copper wire. And I could just include some of it in the kit. But leave the rest up to you. I did it with turning mirrors from PHR sleds, but rog8811 used dichro's from PS3 sleds.
Anyway, if you try this, just be warned that it is very meticulous and difficult to get good alignment. But in the words of rog8811, 'it can be done'!
10440 Battery Mod:
Here's a nice modification for using a rechargeable 10440 battery instead of the stock batteries.
This modification uses a silicon diode to drop voltage on the 10440...
Current Draw:
With this mod (using the silicon diode), the battery current draw on the 10440 battery, with both lasers on, is 175mA's... It is the same current draw using the 2 X 'N' size stock batteries. (with no silicon diode) This tells me that the dual driver board on this little pointer is regulating very well!
(or this mod mimics the stock batteries perfectly)
Now you have a choice of using the standard 'N' size batteries, or a 10440 rechargeable. Because as you can see from the pictures, the plastic sleeve that holds the custom spacer in place, is easily removable!
If you do this project, and you decide you would like this battery mod. I will make you one for $25 bucks. (the circuit board/spacer/silicon diode, assembled) It takes time having to re-size the board and stuff.
I would leave the Pepsi bottle sleeve part for you to do...
Hope you enjoyed this project!
