Since I joined the forum in 2007, one thing has plagued the red laser build. This
not only applies to the handheld, but also the labby.. -Neg grounds
Now many of us like red, and when we build one, are subject to limitations, mainly driver variety.
Many of the drivers, we use will not work with a red unless the diodes are electrically isolated.
But in isolating the diode electrically, also impedes the flow of heat into the heatsink.
In turn you get to use you favorite driver, but not have the benefit of a solid thermal connection.
What I have done is take a standard LOC and various other red diodes with a -neg ground, and
re-route the -neg lead wires to the unused pin. The lead is then soldered and you have a neutral ground
diode
Turning this >
into this >
Considering what powers the average builder runs their diodes at, you want to flow as much
heat off as quickly as possible... This counts even more when you spend extra on a copper
heatsink, and have to isolate the mount. Its a waste.
I will be offering this service to anybody interested. Diodes with a can must be de-canned
in order to perform this. LCC diodes as well as some other reds require an internal 3rd pin
extension in order to re-route the ground.
Pics will be added shortly of before and after..
All diodes will be tested before and after, and any damages covered. In other words, I break it, I buy it. :san:
I have done this proceedure to about 50 diodes To gain a good solid grasp and success of each step..
Note, I dont accept diodes already mounted, too much room for error getting them out of the mount
without damaging.
Pros:
-Better thermal transfer
-Wider variety of drivers ex. boost drivers with a single 1.5V alkaline
-Isolates for use in arrays, and RGV setups
-Makes your diode a little more unique
Pricing:
-Neutral grounding open-can, 5.6 / 3.8mm- 10$
-De-canning-5$
-Internal 3rd pin extension (LCC diodes or PHR)- 5$
Message me for payment, and post any questions you may have :beer:
*EDIT
Teaser video.. This was one of the first diodes I did this to. The idea in
this vid was to get the ground line prepped, but does not contain the soldering.
I will have to make another video to add.
To give an idea of the scale, this was at 30x magnification, with the cam in macro,
and a 1.5~2x optical zoom. The razor used to clip the lead is a standard medical grade scalpel.
I added some music so you don't have to listen to me repeatedly hold and releasing my breath lol.
Also note, you only see one pin in the video.. That diode was a LCC. In a normal
LOC, both pins are long and do not require an extension..
