Ok, here is my 445nm brick
I have another diode and an aixiz glass on it's way for my scanner, and I was having so much fun with this one I thought i'd make it a little neater.
Specs: It has power control! I have a 1 ohm 5W resistor to set the low point (1.2A), and a 5 ohm 15W potentiometer for adjustment. This gives me an output range of just below lasing, to close to 1W (After crappy acrylic lense).
As you can guess, I used a LM317 driver. It has a 8 AA battery holder, as well as a DC in jack.
You can tap the red button lightly for a momentary flash, or push it down and it latches for hands-free.
Diode is in an aixiz module, which is inside one of those 70mW DX red heatsinks and screwed to the enclosure (die cast Aluminium)
Even with the acrylic lense (which somehow hasn't melted yet), a single quick tap of the button can light matches.
Although, the acrylic lenses totally suck for good looking dots and divergence, thus why I decided to make a porta-labby with this one, and save the A140 diode and glass for my scanner
I was making a video and the batteries went flat, so I'll do it again and upload a bit later| EDIT: . I was planning to add a keyswitch, but my budget didn't stretch to it today, so I just need to be very careful how accessible it is for now.
I love these diodes (Well, not the multimode dot)
Cheers,
Dan
