Hi there! I bought this driver to drive a NUBM08 diode, but before I connect it to the driver, I would like to test it, but I don't know what to look at.
My idea is to connect three diodes in series with a ampmeter to make a test load and conect a osciloscope in paralel with the driver output...
Hello! What a big time since my last activity! :)
I have a laser printer/engraver that is powered by a 1,6W 450nm laser module and I can get pretty sharp and deep contrast pictures on MDF sheets.
The best speed for printing is 1400mm/min which is very slow, but was the fastest the machine...
Hello! I recently disassembled my PLTB450B laser to use it on a CNC project of my course, I already got the machine up and running, but I stuggled with the laser part.
I bought this driver to use with the laser, it claims that have TTL, needed for my project.
I did the soldering of numerous...
Hello, I decided to risk my money into a laser from Aliexpress, I expect at least > 50mW from it, so if it burn stuff I'll be happy.
The store are located at this address 'http://www.aliexpress.com/store/1512025', soon as I bought the laser, all the products was excluded from the...
Sometime ago my uncle told me that he wanna use two speakers into her computer, he asked how the connections should be done, I said that to use the full power of the speakers he will need a audio amplifier, since I like to build things and had many experiences building audio...
After about 2 weeks I got some aixiz modules to start my new generation of lasers. This is my FIRST build with aixiz module, so, it don't looks so beautiful than my other DIY lasers.
I used a 300mA linear driver from a dead green laser pointer, a gear as heatsink and PVC water pipe...
Hi! After using much the lens/housing from DVD-RW to make my lasers, I decided to start in the aixiz modules world.
To start, I got 5 of those modules and got a LPC-815 to play with it.
I pressfitted (that word is right?) the LD in the place, screwed the lens on it and powered it on, but I got...
Today I finished my 450nm laser! The decision of make a DIY laser was done here and the full project was developed here
I got all the most important parts from China, with Aliexpress. All the parts took about 3 months to arrive!
The LD is a PLTB450 of 1,4W, driven at 1,2A by a...
Hi! I was playing with my 650nm red laser, collimating and defocusing the beam, and, suddenly, my laser diode died!
Now, I want learn from this, but I can't understand why my laser died.
I was using a little lens from a DVD sled (the one with 6mm) and a big glass plano convex lens, the first...
Hi! I wan't make a driver for my Nichia NDB7412T, I have a 7.5V 4.5A power supply laying arround.
I wan't use a 1.2R resistor to get 1A from the LM317 but I ever used a power supply of 9V ~ 12V for this.
I'm afraid if 7.5V is enought for my laser diode and LM317, I wanna get 1W from this...
Hi! I ended changing the lens of my last red laser, I optimized it to burn at various meters of distance, the last test that I done was with a black baloon at 4.2m! And the baloon popped instantly!
Thats the coolest thing I ever done!
I think it can do the same at 5~6m, but due to the lack of...
Hi all, I hope somebody will enjoy this beam shots. :wave:
Here I use almost two type of lasers:
2 X LOC @ 415mA - 250mW 650nm
1 X DPSS 532nm - 75~100mW
And, only one beam shot of my died 405nm laser. :o
So, let's start!

Hi! I was searching for 445nm lasers in aliexpress and found this:
Link on aliexpress
It is suposed to be a 1W of 445nm, and is from skylaser(s) (i read some good reviews, but found that it have a bad reputation here).
I was abble to get it from U$87.91, now is U$99.90.
Since I don't have...
Hi! Here you can find what happened with my 405nm laser.
After some time collecting the parts, I finally was abble to assembly a 650nm laser within this host and driver!
I don't know the current of the driver, but I put a LOC on it and is very powerfull.
Here you can see the...
Hi! I'm building my second red laser project, is a more compact version of my actual red laser. It uses a 24X DVD burner laser diode (from a LG GSA-H55N [my favorite burner for getting LD's]) that runs at 415mA, I don't know how much mW they put out, I think is around 250mA, if someone know let...
Hi! I got a new Laser 303 100mW 405nm, works great and is very powerfull.
When I was putting the battery to recharge, I accidentally drop the laser head into the ground. The laser was fine and working perfectly, but the beam is now unfocused :mad:.
I observed the host searching for loose...
Hi! Today I disassembled a Samsung SH-S182D DVD Writer to use the LD.
I extracted the LD sucessfully, is a frame type laser diode, to test which is the red one, I used a driver set to 100mA, what is a secure current.
Here some photos of the LD:
But if I remember, this LD works with less...
Hi! I finished mounting my powerfull red laser using a GSA-H55N laser diode and a DDL driver set to 415mA, after some play burning plastic, I decided that my laser is too dangerous and need some way to limit the output power.
The circuit I used is this:
For some days it worked like a charm...
