[size=+0]Making a pointer
[size=+0]To make this into a reasonably sized hand held I needed to turn the output through 90 degrees for this I used the turning mirror from the PS3 sled.
[size=+0]
[size=+0]It needs to be stuck onto the optical block like this
[size=+0]
[size=+0]Preparing the optical block
[size=+0]
[size=+0]You will note that I did this before sticking the modules in place. To get a flat surface to mount the prism block you will need to cut, drill and bend the stainless cover that came off the back of the sled. This was carefully glued in place with Araldite.
[size=+0]
[size=+0]The prism was then glued in place, I wired up the LD’s temporarily to make sure that I was gluing this on straight, it is held in place with Araldite.
[size=+0]Once it had dried I used some more Araldite to fillet the edges to ensure a strong mounting.
[size=+0]
[size=+0]
[size=+0]Powering it up
[size=+0]You may have concerns about powering this up as the modules have different polarities:-
[size=+0]Green positive case [size=+0]Red negative case [size=+0]Blu ray either polarity [size=+0]I suggest to keep things simple that you supply the green from one set of batteries (3.6v) and the red/blu ray from another set (7.2v). If you go this route do not connect any part of either supply to the case of the finished laser and it will work fine.

[size=+0]Battery holder
[size=+0]I decided to use 2 supplies so built a battery holder for 2off
RCR123A and 1off CR123A, it is made from a piece of plastic tube cut down the middle.
[size=+0]Spacers were cut from plastic scrap
[size=+0]Contacts were odd bits of brass sheet
[size=+0]1 spring came from the green module
[size=+0]The other was just knocking around
[size=+0]The whole lot was assembled with superglue and Araldite.
[size=+0]
[size=+0]
This will work together to give you this....
