New FOCUSABLE 200mW Red on DX

[phoenix77]

I ordered mine also, & now the waiting game begins. Actually I didn't order mine, a good friend of mine sold me a BLU-RAY laser a couple of months ago/with case for $75.00, with the understanding that if I took good care of it, he'd buy it back for the same price. It only puts out about 2 or 3mW's, & it's not really a TRUE BLU-RAY, more on the violet side, but other than making certain objects fluoresce when you shine the spot on the item, you really can't DO anything with it. I've had it for at least 2 months, so to sell it back for the $75.00 sounded good to me! I will miss the unique color that it puts out though,& whoever made it did a GREAT job on it. It's only 3 and 1/2 inches long X 3/4 inches in diameter & runs on 1 AA battery.Then this 200mW FOCUSABLE red came out so I called him & asked him to order me one( instead of paying me the $75.00 back) with extra batteries & a charger. Then, when it gets to his place, he can pkge. it up better & relay it to my place. He said COOL & I said COOL so everything is COOL!!! All I've got to go now is play the waiting game!!! P-77 PS Maybe, sometime in the future(if he still has it & will sell it for the same price) if I have the $ I'd like to get it back 'cause it's such a cool color! Phoenix77

I ordered this too, its been waiting on supplier for a week but its back in stock today so i hope that it will ship by Wednesday next week, fingers crossed

Also when i get it i am planning to mod it to take 4 'aa's, it should have like 4 times the battery life and all i need to do is get a 4 "aa" holder and hook it too alligator clips then hook those to the case of the laser for negative and the spring on the inside for positive.


...lazer... ;D ;D ;D

I got mine today and it seems close to 200mW, it lights white matches near instantly. Also the head on mine is not wobbly, it actually seems well built. This thing is a steal for only $54.

Mine isn't wobbly either. However, the focusing knob separated from the collimator. I panicked at work, thinking I broke it, but realized, this was time for the teflon tape fix. Luckily I have some here at home and in a rare moment of DIY-ness (I'm pretty bad at this stuff - really!), I put some teflon tape on the collimator, screwed the head on gently and now, the focus works great - and it's a bit tighter than before.

Now, it's time to burn. Sharpied/dark matches light instantly, but I have trouble with white matches. But this may be my problem, not the laser. When aimed at leather, loads of smoke instantly pours out. I'm sure this thing will shred balloons. Anything plastic smokes when the laser is aimed at it.

For 54 bones, it's worth a minor fix.

This is for all of the people that are waiting, and especially for the people that this is their first burning laser. Just think, you will ONLY have to wait a month or five to get this in the mail!

BTW, the movie is 11MB, deal with it ;D

This movie is also 11MB, live with it ;D

You are my hero.

Damn, I'm going to have to wait a month... Oh wait, I typed this while I was holding it. ;D

How the **** did you light a white match?!? I have red DIY lasers with verified powers of 185, 250 and ~300mW, but i can't light a white match, nor would i try. They have to be brown, green or sharpied..

Can you light a red match?!? I want to see that.


Just looked at the vid.. Never tried this type of match before. Need to find them i guess.

This thing can kill red matches, they are more absorbent to light than white because the color red in matches doesn't match the color of the laser so not all of it is reflected, less of it is reflected than from a white match. And I have a bunch of different white matches from different companies and this lights them all, for me it seems like lighting white matches easily comes at around 200mW.

Here is a video of a reddish match being lit instantly with the laser, I'll try to find even darker red matches later.

What is the distance to the match, when you are doing this? EDIT: These are also paper matches.. All i ever tried were wooden ones. Need to get me some paper ones.


Oh, and did anyone measure if the current changes with the battery voltage? Do we know if it is regulated or not?
If the driver board is easily accessible, some pics of it would be greatly appreciated.

 

[styropyro]

The distance to the match was about 6 inches or so, it was close enough for the dot to be focused to the tiniest dot I could get.

I'll be adding some circuit board pictures in a little bit.

 

[styropyro]

Ok here is a picture the front of the circuit board, I can give you a much more detailed picture if you need it, I took the picture at 7.1MegaPixels.

 

[styropyro]

Here is the back of the circuit board, I can take more pictures if you need them, the circuit board is easily accessible.

 

[IgorT]

No need for higher res. These are fine.. Very nice macros btw! Can you read what the IC says? I would like to look up the datasheet.

The batteries go in with the positive potential facing the spring, right?

 

[styropyro]

Here's the IC, do you need me to remove the little blob of glue off of it?

Edit: batteries go in with the negative on the outside, positive facing the spring on the inside. It's the opposite of most pen lasers!

Oops, picture seem to have gotten flipped, I'll fix that
Edit2: Fixed

 

[IgorT]

You've done more than enough. I only wanted to know if you can read the letters on it. BTW, i still see it flipped, but i'll rotate it myself.

The thing is, even if the circuit is capable of regulation, it is not necessary, that it actually does regulate. Only current measurements with full, half empty and almost empty batteries would answer that. If the current doesn't peak with full batteries, and remains the same at two or more battery voltages, it is regulated. If the current peaks, quickly drops to a lower level, and then decreases very slowly, it is not.


Green lasers have batteries facing the other way, but that's because they use IR pumps which have the positive connection at the base of the diode. Red LDs have the negative pin at the base, requireing the battery to have the negative potential touching the body of the laser, and the driver to be different.
