This is a one-of prototype of mine.
An Ophir head from ebay is included. (New Old Stock)
Power from USB, OR from the included rechargeable Battery
Backlit screen, that is visible with 445 protection glasses on
It powers the 20C-A with +/-...
I have 4 for sale atm
They are the standard AAA pens
Just tested all of them
with fresh set of good AAA's
Testing done at ~25c
Sold1: 100mW peak; 100mW at 30s; 35$ (starts around 80mW and goes up)
Sold2: 100mW peak; 65mW at 30s; 30$
3: 70mW peak; 60mW at 30s; 20$
Bought this a while ago with a dead driver,
Driver has been replaced, and it works great.
Really hate to sell this one, but need money for tuition...
Price is 100 + shipping
ATM only willing to sell the the USA
Shipping + insurance will be $10
Price is $14 Shipped to the USA,
Additional pairs are $8 each
These are the best safety glasses I have found that don't break the bank.
Even if you have an expensive pair of safety glasses, these are great for guests.
Also if you are trying to record or photograph your laser these can be...
I had a lot of free time today, here is what I acomplished lol:
I Soldered it by putting the whole heatsink in a frying pan for half an hour :D
Only problem now is I cant seem to solder the electical leads with my regular 60W soldering station
Because the heatsink is working to well!
Designed a PSU for running the PT54 Led at full power,
Here it is:
OP Amp - Needs to be rail to rail, or at least have a good voltage swing
it also needs to be able to operate properly at ~3.5v
Mosfet - Needs to have a low RDSon at ~3V Vgs
Resistor - the 0.02 Ohm resistor needs...
In the datasheet the max junction temp is 80c
I found the Leds on chip Thermistors B value to be ~3400
and its 25c resistance is 10k omhs
Based on that I can find the Thermistor temp
But I couldnt find a (Degree/Watt) number
connecting the Thermistor temp to the junction temp
Going to be making my self a new calibration laser this weekend.
I'll be using a Tec, Controlled by a microcontroller, to regulate the temperature.
Diode with be an M140 running at about 1W.
Should be fun, I'll update this thread with my progress
1)6A, 5V PSU from...

FS is a 445 Small Sun Build
Diode is a high power 9mm
Lens is Single Element 9mm lens
2.2A Driver current
Recommended duty cycle is 30s on / 60s off
From a room temp start its ok to go for longer
Just be smart, if the lasers feels hot in your hand, let it...

For sale is a very nice 635nm Laser.
This laser uses one of the 500mW 635nm Mitsubishi diodes
The lens is a 650-G2
Diode is run at 1.5A with an X-Drive
Tec is also powered by an X-Drive, at 1.8A
The 2 Heatsinks were made by Eudaimonium :thanks:
I am starting another "Juggernaut" Maglite build
This one will be using a 500mW 635 Mitsubishi diode
I am expecting 1.2W+ out of this guy
Not to mention this build might actually be close to 635nm (Chilled Diode)
True 635 is quite a bit birghter per mw than 445
The 2 part heasink was...
I am considering one of these for a TEC,
~6.5V @ 2A from 2 lithium cells
What is the max vout of these drivers?
Which one has the lowest Dropout?
Will the new BlitzBuck V4 use the same IC as the V3? / would one work better than the other?
Also does anyone know what a good PWM frequency...
Nice sturdy gray MagLite build for sale.
Price Drop : $295 + shipping
2x 32600 ~5000mAh batteries included
1x pair of safety glasses included
Charger also included
Lens is the High power 9mm lens
Driver is custom made, using the LT-3083
Duty cycle won't matter in most cases,
Would this work?
With a small Cylinder Lens sitting right on the diode?
Is this how a FAC works?
The angle of the wider axis is 35 degrees, and the narrower one is 7.5 degrees
Is there a simple calculation of the the focal length would need to be based on getting 7.5 degrees to 35 degrees?
Nice 1.3W laser in a SH-032 Host
Runs on an 18650 (Included)
Charger and safety glasses are also included
Diode is quite efficient, and has a duty cycle of 2on/1off
G2 lens (Optional) (1.3W is with G2 lens; ~1W w/o G2 lens)
1A Aixiz Boost Driver
I present my new and improved LPM design: (Now a Release Candidate):san:
LPM is powered by a 3.3v LDO, So no crappy 9v batteries, and no boosting regulator in this LPM :D
The ADC and LDO are High quality, High accuracy, and Low noise.
made by Texas Instruments ;)
The LPM is also very...
