While we are pondering methods to turn a sow's ear into a silk purse, it may useful to consider the intended purpose of this device. This has me wondering about the equipment in which it is used, I wish I knew more. I suspect that the diversity of diode characteristics is much larger than we...

Sorry likevvii, I have no clue about glue. I used Bondic Liquid Plastic Welder because that's what I have. It seemed adequate.

Propylene Glycol boils at a much lower temperature: 370.8°F and is non-toxic and safe for fog. Some water would help but a rice cooker will not be able to get hot enough unless the thermostat is bypassed - probably not a great idea. I would try heating fog juice in a pan on the stove. Use a...

Optional: draw around the lens array with a permanent marker if you will want to reattach the lens array later on. The alignment of the lens array, with the diodes underneath, must be very precise and this might simplify matters a little. A few small spots of UV activated adhesive around the...

I'll throw in my two cents, which is all that all I have. Get some 150 pound capacitors. Determine the dimensions and mass of the piece of air you wish to make incandescent. It takes one nanosecond to produce a piece of light one foot long. Find, at any wavelength under consideration, the air's...

yes, coated of course Ezackly I need to decide which configuration to undertake and leave half done.

~ Good news, slightly. Removing the gang lens will not affect the seal on the window beneath it. I am disinclined to lose my gas! Check this: ~ ~ The green adhesive is the seal on the diode chamber window. I removed the gang lens by cutting it's adhesive with a razor blade. By the way...

A thermal print of the NUBM34 was made with the lenses reattached. Three diode rows were powered. That the prints are rather distorted suggests that the lens alignment is slightly off, I suppose. I'm considering optical options, while attempting to decide on the most entertaining purpose for...

I thought it could be interesting to see what the beam pattern looked like at the surface of the diode window, with the gang-collimator lenses removed. A piece of thermal paper was placed on the device, and one row of diodes were supplied with 1 Amp for 3 seconds. An image was created on the...

A stainless steel bar was placed on top of the NUBM34, without lenses. The weight of the bar presses the device against a large aluminum block which serves as the heat sink. One row of diodes is aligned with one edge of the stainless bar such that the laser diode emission is visible on the side...

A couple of close up images, of marginal quality, at best: The 45º mirrors are flat; some beam-forming is performed by the lenses which are above. (The beam forming mirrors were removed to permit inspection of the diodes & mirrors.)

I received a NUBM34 from "Newgazer "on eBay. It was ordered April 29, delivered May 7, by FEDEX, no problem. The 24 diodes are mounted on the base plate, each has a bypass zener diode. A mirror, at 45 degrees, reflects the output normal to the face of the device. I have limited the current...
