attached you will find pictures of tmy laser driver test jig 2.0.
I like this construction, because it is simple to contact any driver with this jig.
I made the connection rods from 1,6 mm bronze TIG welding wire. This rods are hard enough to produce sufficient tension to the contact...
please don´t quarrel!
As I said, it is just a quick and dirty construction. Paul is right, I need another contact, if the holes of the driver output have a different distance.
The power input will work for different distances.
I always got good advice from Paul and I think, he is...
thank you for your information.
I finished the driver test device. It works well, but I do not like the design. It is to complicated and can`t be changed easy for drivers with different dimensions. For the power supply, I used two Li accus, so the driver is still alive.
my test device for laserdiode drivers is under construction. The construction is more difficult, then I thought before starting.
The contact holes of my 1500 mA driver have a distance between 8 mm and 3 mm. The problem is the 3 mm distance.
I am still thinking about how I can contact the...
the positive cable of the load was soldered, the negative was screwed, so both connections well done. After that, I connected the Driver with the power supply.
Nothing happened! After that, I checked the dummy load again, everything was ok.
Then I took my last 5500 mA Driver and set...
today I had bad luck again with a 500 mA buck/boost driver. It was not from DTR!
I connected the new driver to my dummy load of 6 diodes and a 0,1 Ohm resistor. Nothing happens, no curent draw from my laboratory power device.
After checking the wiring, the same result. Is it possible to...
I also set some Drivers this way. I think, it is a save way, if Driver and Laser Diode fit together.
It will not work, if you use a high power Driver with a 200 mA Diode.
For current setting i use this nice multimeter...
what is wrong with a 1Ohm dummy load resistor?
Have a look at the DTR thread: https://laserpointerforums.com/threads/dummy-load-batteries-for-m140.87938/
I use 0,1 Ohm and 1 ohm resistors, it depends on the maximum current.
nice attempt. I think, it is not your Video, because:
Welcome to Black Beard Projects!
I’m 25 years old and live in Italy....
On my YouTube channel you’ll see all kinds of DIY projects. I have been doing things like this for years and now I want to share this passion with you.
since I started to join this forum, I built some custom made and/or modded flashlight laseerpointers with different colours and laser power.
1. 405 nm 500 mW
2. 450 nm 1,2W; 1,7 W: 7W+
3. 465 nm; 1,8 W
4. 488 nm; 150 mW
5. 505 nm; 150 mW
6. 520 nm; 800 mW
7. 635 nm; 200 mW and 700 mW...
I like the second laser. Is it build from aluminium?
Can you please give me a tip, which tailcap switch I can use for my own custom built laserpointers?
At the moment I use switches from cheap flashlights, but they are not built to handle big amperage.
a week ago, I got my new diodes from laserlands together with a free gift, an antistatic band to connect with my wrist.
I tested one diode with my test device and it worked fine. After connecting it with a tested 500 mA driver, I set the driver to max. 300 mA.
One of my glas lenses...
