BradleyJay's Sentinel Pointer Build - 650nm 3mw

So I built my first pointer using a Sentinel clone ecig battery tube mod from fasttech. I used a small axiz focusable module with driver that metered <3mw of 650/660nm.

Here is a beam shot:


Here's an image of the dot, the slight scatter is caused by reflection back onto the top cap surface and back as well as some scatter hitting the screw socket.


This slight scatter ring could be reduced by painting the inner 510 connector socket black. Doesn't bother me enough to do this yet... This shows the front lens and top cap:


The parts I used are all shown below:


It is basically heat sinked by aluminum but is isolated from the casing. It would be possible to adhere the module to the top cover to make it focusable without minor disassembly, but I generally make such infrequent adjustments, I left this out to make the build more flexible. The positive connection is sent through the casing and requires the top cap to make a good connection with the module body. Below shows the top cover removed and the insulated module:


The back side of the heat sink/head has an insulated screw making the negative connection to the driver:


The momentary switch has a lockable nut to prevent pocket-firing. Below shows the locked position:


And lastly, a full body shot of the entire build:
