I have been in touch with member cyberdoc by email. He is a physician by profession, but has been in and out of the hospital at UCSF for uncontrolled bleeding, renal failure and neuroendocrine cancer. He has been hospitalized six times since 7/4/19 alone and is currently so. For those who don't...

I just got back from my doctor's appointment today and found out that last year's congress and this president passed some new laws on how much pain medications one can have and what other drugs they can no longer take if they are taking opioids for chronic pain. Now you can only get the...

I have been meaning to post this for over a month, but lacked some decent beam shots. I think these should do for now. This build was done using the NDB7675 462nm diode driven at 1.8 amps with an X-Drive and using a G2 lens for an optical power of 1770 mW. I measured the wavelength at threshold...

I recently won an auction on eBay for a new NDG7475 diode and decided to put it into a special host I had been saving for several years. It is the MS-SSW-II host from sinner also known as sinner's secret weapon. This is a large host which takes two 26650 batteries. I wanted to drive it at 2...

I bought this laser from Shenzhen OPTlaser Technologies for $30.00 which included the driver. This laser is a pure lemon yellow color, but because of the way the RGB pixels in the cameras make yellow out of red and green, they all come out looking green. It didn't matter what camera I used...

I finally found enough time to put together this thread showing my <488nm Sharp diode EDC build. I used a host I got from Rich, Lifetime17, which had an ML501P73 diode in it. It has a Nano Boost driver set at 275 mA in a copper module. As can be seen by the first photograph, it is in a copper...

After much waiting and several hiccups along the way I now have a new 493nm laser in a 501B host I got from Lifetime17. Thank you, Rich. Also a great appreciation for the free host for my 502nm build. The host is not that fancy, but it provides enough passive cooling through its heat sink to...

I have one of the Sharp "495nm" diodes for sale at $60.00 plus $7.20 2 day priority mail if inside the states. Outside will depend on shipping charges. Since I have another package going out on Tuesday, if someone grabs this tonight or early enough tomorrow, it will go out on Tuesday and you...

This is the Sharp #GH04955A2G, 495nm laser diode. Unlike earlier versions of 480nm and 505nm, these have no micro-printing around the diode's window. These new diodes are difficult to describe in terms of their color. To me they are right on the edge between blue and green. It is a spectacular...

So, I finally got my obligations to other members fulfilled and had time to finish my two newest builds. A 477nm in a 501B host with a Lifetime17 focus knob and a 502nm in a lifetime17 501B build. Both are over 100 mW in power and use the acrylic stock lenses to eliminate the rectangular...

Last October the FDA proposed banning laser pointers that are not red or red-orange by designating green, blue, violet, yellow as well as other colors as "defective". These currently account for 95% of the 7000+ reported incidents per year in the U.S. where a laser beam is aimed toward an...

This is a review of a laser sent to me by Rich, Lifetime17 as a gesture of kindness. It is an ML501P73 Mitsubishi diode in a copper heat sink with a G-2 lens inside a copper focus knob. He sent it with an Efest 700 mAh 14500 battery. It has a nano drive inside a camo finished Cree Ultafire...

This is my over due review of the laser I got on the free laser giveaway from tommy at laserpointerstore.com. This laser was sent by DHL which was very quick in getting this laser to me. The shipping cost me $20.00, but the laser was free of charge. It took about three days in total to arrive...

This is a Mitsubishi ML501P73-02 laser diode driven with a lazeerer continuous ground adjustable X-Drive set to 1300 mA and put into a sinner's Cyprus II all copper host. It peaked at a little over 1 watt. I purchased these diodes a little over two years ago when they were much more expensive...

There is a new red laser diode out there and it is the Mitsubishi LPC-840. It is rated higher than the LPC-836 and should be able to be driven up to 500mW. It is rated for 390mW. They are offered on eBay and the single diode price is a very reasonable $15.01. I ordered one right away. Here is...

As some of you already know and everybody else will learn, this group buy is for the S1 single element lens in a brass housing, M9X0.5. There will be one spreadsheet here and another one on thejoker301's website. These lenses turned out to be of greater quality than the G type lenses that we...

I came across these G-2 type lenses similar to the ones from the group buy from O-Like, only these are better by 6-8% in a side by side comparison. I bought four lenses in the group buy, but I also had ordered 10 lenses from Techhood that cost me a lot more than the O-Like lenses did. I have a...

I received a new Radiant X4 LPM today and the meter's program has malware included in it. As soon as this meter arrived I stopped everything and began setting it up. I have Norton security by Symantec on my computer and it stopped the program in the meter from loading. At this point I tried...

I have been looking for an 11.5 mm outside diameter module to hold a 5.6 mm TO-18 laser diode. It would be great if the diode press for the Aixiz module TO-18 LD would work to press the diode into it. I thought I saw a thread on this type module, but I could be mistaken. either way, I can't...
