    DX SD-303 200mW Review

    Yea, I'm on mobile. It's rather a major PITA to edit, found that out with my typos, that's why I did that. Things have definitely gotten more strict around here since I joined up.. Well except for me getting into a forum fight with Senkat because he threatened to find and physically hurt...

    Another SD303 thread/question.

    I hear ya there. I may just convert it to a 520nm. Going searching for parts, any recommendations are appreciated though. I'd love to hit the 200mw or up mark. Thanks guys

    Another SD303 thread/question.

    Hmm. I just removed the diode from the module (dead. This is what killed the laser). Inside was a small domed lens, spring loaded to keep it a few mm from the diode. This lens was in between the crystal and diode. I'm learning, still confused on that one's purpose, unless it shrank the...

    Another SD303 thread/question.

    I'm on mobile, no way it seems to upload pics. The module is simple. It has a brass housing with a 3 pin 808nm diode pressed in. (was) Glued to the business end is a off-center slotted collar, with the tiny crystal glued in. Glued to that collar was a small round plastic lens, steep...

    Another SD303 thread/question.

    Chinese lasers are almost sways overdriven.. I learned that long ago. But hey for under 20 bux what the heck lol. I now have a replacement 303 on the way, the seller sent me another, no need for me to return the first luckily, no charge. Also spent $7 and $6.55 on two 301s. They should...

    I want to buy a green laser for astronomy.

    Hmm. I can't really recommend them, but if you want cheap, and have a smartphone, grab either the Wish or Geek app, pay less than 20 bux, and have an SD301 or SD303. They seem to be at least 80mw, and shoot a heck of a beam into the sky. IR? Well there's no filter, so know that...

    Another SD303 thread/question.

    Yea, although every green I've had put out a maybe 1.5mm thick beam, same as this one. My bluray and reds that I built those years back put out a ballpark 3mm by 2mm beam. Definitely in the lenses. I would think for burning without focusing down, the small beam would be better. I really...

    DX SD-303 200mW Review

    Prices, well on the Geek or Wish apps, anywhere from $5 to $30 for either a 301 or a 303, plus a couple bucks shipping.

    DX SD-303 200mW Review

    I heard about the airport situation. Why anyone would be so dumb as to do that I have no idea.. It's crazy. So far the seller asked me to try another battery, and if that doesn't work he can send a new one. I explained that I have two new red "ultrafire 4000mah" batteries, both fully...

    DX SD-303 200mW Review

    hakzaw, was that question for me? I ask because u mentioned a bad laser. I've already contacted the people in China where I bought mine from.

    Another SD303 thread/question.

    Cool thanks for the advice so far guys. My fat beam reference was to my PHR803T build from 6 years or so ago. Compared the the DPSS greenies , the beam is over double the thickness. Same for my red burner that has since went LED on me. I actually have an SD301 on its way, a whopping 9...

    DX SD-303 200mW Review

    I got mine thru the Geek app. Seller Orient Seduction. It was 14 bux shipped.. It lasted 3 days, maybe an hour or so runtime, never on for more than 30 seconds or so at a time. Went bright, then dead. The driver still works, it will run my old pen green module. I've asked for a refund...

    Another SD303 thread/question.

    Cool beans. I'll update my profile, I'm in Northwestern Pennsylvania. The lens I would need is small, threads into the brass housing of my old green module. I have the 303 torn down. 12mm seems to be the size. Where I am lost is the lenses needed. The 303 had the collimating lens on the...

    Another SD303 thread/question.

    Hello everyone! Longtime member here, been forever since I have posted though. I grabbed up a $14 shipped SD303, have had it for 3 days, and it is dead. Lol even my old "150mw" pen module is still working from 5-6 years ago, still as bright as it was new, but the lens sucks on it, lots...
