Well folks, I am continuing my longtime tradition of showing off with almost every build I make, so this cannot be an exception as it's the best laser I've built in my life, so far.
Well, first off, let me post some pics of internal setup, to save words:
Bill sent this host he needed no more ... spring was a bit rusty, so I replaced it
Old spring next to driver pill.
Now, the boost driver
Custom made to fit the pill, also gave it a biga$$ output tantalum capacitor.
So okay, here we have a diode and driver soldered together
Now, how is this mounted you may ask?
Well, the case of the diode (and entire host) serves as negative INPUT to the driver, and positive input is made via spring-switch contacts.
So, as the diode in it's heatsink is pressed into the pill, the wires will put some tension to the driver and keep it pressed against the PCB in the bottom of the pill. So, some thermal paste is used and the driver is well heatsinked, ready to endure countless operation hours.
Heatsink of the diode is pressed into the pill, like so:
Positive input wire is soldered to the base of the spring, ensuring contact.
Now, entire pill heatsinks both the diode and driver. Total of 1.2 Watts need to be dissipated.
The laser head assembly threads into the switch barrel like so:
Stronger spring makes good tension on the threads, increasing thermal conductivity.
And finally, the head with lens holder is threaded on top of this:
The alluminum of the holder presses against the diode heatsink, making the diode even more happy.
Finally, lens is threaded in:
And voila...
Yeah I was feeling trigger happy with the camera...
GGW and PHR comparison
Dot comparison shot attempt, camera does not do it justice, visibility ratio is the same as the beams.
Total of 340-350 mA current draw from the full battery, measured 175 mW output,
Diode purchased from Dave - exeptionally long wavelenght diode. Beam 4-5 X more visible than PHR which is only half the power.
Bill519 - special thanks for the host which was included as freebie from one major host purchase from him, he said he does not use it no more...
I cannot see why. Kickass host, that is.
Very special thanks to my friend, x90z75ek , who funded the diode.
Thing is, neither of us could have a 6x build on his own. He could maybe afford it, but cannot assemble it (yet). I can assemble it, but cannot afford it.
So we compromised!
The build is effectively "ours" - cooperation for higher power lasers FTW.
Also, here is a video for your ... well, enjoyment.
Thanks to Silvershot for music reccomendation!
