Well, if they aren't crazy we do not want them 
I wanted to create something special, with a beautiful host, a fantastic beam color, and a touch of class, so this is my
plesure to introduce You my new Cypreus XL with NDB7675 1.7W 462nm diode 5 microns gold plated.
Originally the host and the inside parts were plated with 24k gold at 4 microns, but the result was a host with a cool
color like a lemon, so I presented again the host to the galvanic company for plated it again with a more warm tonality.
To obtain the beautiful color the company used a mix of gold, copper and cobalt, and the result was a 22k gold with
1 extra micron thickness added and a warm awesome color (for a total of 5 microns, about 4 grams of gold along the entire host).
First of all, a little mod to the Cypreus switch.
With the help of a small amount of alumina thermal paste, I have glued the battery contact to the back of the switch:
The terminal contacts were soldered, then the switch was firmly locked into the teflon part:
Also the other battery contact were modified. First of all, I have soldered a spring around the contact, then in the top of
the spring I soldered a small gold plated neodimium magnet to assure a perfect contact and a right spring pressure
against the 18650 battery:
The lens crown pressed into the focusing part with the help of a vice (repertory image):
Lens and diode mounted and locked:
All the parts ready to be assembled:
Due to the extra 4 microns 24k gold plating, the diode fit perfectly inside the heatsink hole.
A little pressure was applied to the diode barrel until it reach the end of the hole.
The wires was soldered to a very small washers, and blocked thru the dedicated screws:
The assembled heatsink:
Just a wrap of acetate foil to avoid battery rattles inside the host:
The masterpiece fully assembled:
The beautiful 462nm color: a pure light blue without any touch of violet
(no smoke and no long exposure were used):
The laser is a dangerous weapon. This is the result of a wrong shot against the curtains of my bedroom ;(((( :
Cypreus II on the beautiful rock solid eye-catching small Manfrotto tripod:
Also the Ophir head was mounted on the same Manfrotto tripod:
Laserbee 7W proof :
The 2 mins performance graph.
The diode seems to be very stable, also due to the excellent heat dissipation of the Cypreus copper.
After 2 minutes the copper is warm but not hot.
The diode is current hungry and I prefer to use hi-drain not protected cells to obtain the best performances
(Panasonic 3400 mAh non-protected cells freshly charged was used for this test):
Burning power video.
The laser was placed at a distance of 60 cm from the pad:
Conclusions: time, money and patience is needed for this kind of builds.
The most beautiful part of the entire project is the construction of the project itself.
Then, the emotion of the first shot, and the fear that something could be wrong
(lately I have destroyed so many expensive diodes that every time that I try a laser
for the first time I shit on my pants).
Then, make a detailed recension here on LPF.
Next step: go on the roof of my building on the fourth floor at night and break the balls
in the whole neighborhood
And finally, place the laser between the other masterpieces while thinking about the next
crazy project to realize :crackup::crackup:
I wish to thank the cool guys that allowed the creation of this piece of craftmanship:
Jordan from DTR, Sinner from Dubai, and the staff of Pittarello Gianfranco of Italy for the
professional gold plating.
See Ya soon for the next creation :wave:
