in mine same RGB 200mw the TTL modulation was not working in the green and red due to a driver defect, here I posted the solution if somebody else is so lucky as I am http://laserpointerforums.com/f52/review-white-light-rgb-400mw-laser-81879.html#post1184933

OK, since I'm always the luckiest one..... my 200mW RBG was not TTL driving the red and green lasers, only the blue one. After several emails with the seller (techood) and since he doesn't understand anything and I did not wanted to send my laser back, I had to check the circuit a little bit...

seems like the RGB I bought is about the same than yours, but mine seems like the TTL doesn't work for red and green... :( your soft gave me some good ideas, lets see how can I make mine work..

Question, do the TTL modulation works in yours? mine arrived and only blue seems to be able to be turned off by putting it to ground, in this case shorting it. when I measure the pins of the TTL, blue (the only one apparently working) has 4v, red and green 2.6v and have no change if I put 5v or...

After my first blue a-140 got bad using a direct drive with an lm317, even with capacitors and everything!, I decided to buy another blue from DTR, this time an M-140, with an x-drive included and the copper/al aixiz from DTR as well. Located in the Dominican Republic, with only a few years...

very cool, I got a 200mw one

Re: DTR's Laser Shop: 445 M140 Diodes $45 Shipped US Diodes-Drivers-Lenses-LEDs & M question, where can i get an aluminium block like this shown here to hold the laser to the heatsink? Two watt blue laser driver 445nm - BOGIN, JR.

Re: DTR's Laser Shop: 445 M140 Diodes $45 Shipped US Diodes-Drivers-Lenses-LEDs & M well, my first laser is gone, I think it was a peak, I had capacitors and everything and happen after many uses and burns, I see now that there are a new generation, I think I had the A model and was driving...

I didn't make it go underwater yet, I need to find a good way that will keep the water away from my laser :) communication is interesting, I wonder how they do to point the laser in the right spot??

a quick shitty video of my laser cutting a soda bottle, how do you guys do to show the beam of the laser in daytime?, in daytime looks very thin, I have seen other videos with a lot of light and you can see the beam very well, maybe smoke added? YouTube - ‪My new toy, 1.2W Blue Laser power‬‏

I'm pretty sure the resistor is 1.3 ohm, the meter meassures accurate. there is no need really for 2 lm317, it does not heat that much, the total heat would be about the same at the end. the nimh batteries I used are 2.9 amps, and they do supply enough power because I use them in my 10w HID...

ok, so I made a quick lm317 DDL circuit with a 1ohm-5W which is really 1.3ohms resistor that I got laying around, tried running it with a test load with 8 nimh 2.9A batteries but where not fully charged and voltage was dropping under 8v, so output was really low at 560mA, then I plugged in a 12v...

thanks, do you have a diagram for an example in how to put the fet? what would you use for oscilator?

hi guys, a quick question, is it ok to connect the tab on the lm317 to the same heatsink than the 445 diode?, I was checking the diode and looks like isulated from the case, is that correct? quick answer apreciatted, I'm setting up a quick lab for my diode just now, by the way, which driver...
