It comes down to the battery. Batteries used for vaping devices are a good choice for high current applications. I have AAA sized that are rated 3A continuous and are fine in short bursts going well over that. The key is to mind the temperature of the cell and proceed with caution. I have...

Not to worry, if anyone replies or not im good either way. I did some further testing and hit 430mW at 400mA, so I think its safe to say its a newer diode than the older dtr threads I went through from 2015 or so. I was worried they may be the older ver that arent prone to redshift or higher...

I got a few surplus diodes on ebay that look to be the osram single mode blues that have numbers on the side of the can: 7H D8 A pic (attached) from a post from dtr shows "batch 2". Anybody know if the didoes I have may be from a similar production time, or perhaps a model other than a...

Not picking at your methods or anything, but why not just run it at its rated current? Then there's no question what power it can reach. You also get to see if there's any anomalies in the wavelength when it shifts, if it shifts etc. I noticed with some diodes when you run them at threshold...

What does that tell you about that one diode that reads the highest at threshold? I have not tried this approach. Typically I go by which diode it is and if there's a data sheet available I set my current limit to its maximum rated current and mark down what output they all have at that...

That is really odd, I've taken apart a130s and a140s, the only time I've seen a marked up phosphor wheel was when the inside of the machine was really dirty. I've gone through several a140s and the only thing I noticed was at the diodes start to burn out after 10,000 hours or so. The red LED...

How would that make a difference? The phosphor wheel produces green and a lighter shade of green almost a yellow. Then there is a dichroic filter on a wheel that produces the reds but only one of those. To my understanding there's only two phosphor Wheels in this machine because it employs a...

Well the interesting part about this projector is the use of dichroic mirrors as opposed to the silver first surface mirrors seen in all the projectors that I've opened. They are used everywhere where the beams needs to be steered. The other interesting thing is that there are two light boxes...

One of my kids pointed it out when watching a Lego movie. The other likes the the contrast and brightness when using it for tinkercad. Though he's expressed more interest in taking a 🪛 to it 😆

I watched a few movies on this machine and I'm not very impressed with the image quality. Too many anomalies in the picture when running HD films during scenes where a lot of motion is involved. They also use a phosphor wheel as opposed to a red LED similar to the BenQ projector with the...

Found it through Google search. "This is in agreement with what DTR and other members said earlier that the less efficient LDs usually have higher wavelengths." https://laserpointerforums.com/threads/test-of-diodes-in-nubm08-block-one-by-one.102804/ So this is the 08 block that I was testing...

I was referring to a scenario where say a block of diodes when tested individually at a given current the lowest efficiency diode in that batch would present a higher wavelength than the others in that same batch. I'm going to have another look with the search, or perhaps I'll try it out on...

Haven't begun the harvest yet. I set it up to use for a few movie nights. First time using a projector with more than 3,000 lumens 😲

Got a question for you folks. I can't find any information on it but I do recall reading somewhere that the lower efficiency blue diodes tend to have higher wavelengths. Now in relation to the nubm 08, is this true and what properties do the higher efficiency diodes present, if any difference...
