Hi, i'm new here an this is my first post in this forum
I'm 21 years old and live in Germany. I love to build special things, I dreamed a long time to build a high powered Laserpointer for my own.
Now I have the machines to do this.
I got all my knowhow from this forum and I hope someone could help me with my problem:
My friend and i crafted some really nice housings for our first laserpointers..
We wanted to put in a M140
Our driver is a 2000mA LED driver and we used four 3v Batteries, so we had a current of ~ 11,6V
Our heatsinks measure about 25mm total diameter
We drilled a seat with CNC and pressed the diode with thermal grease from a CPU in
Well I connected it with the Driver and the Diode ran about 4 seconds.. I think its broken now
Do you have some advices to us, what we are doing wrong ?
Are 11,6V too much current or what?
Or ist it the 2000 mA, I read about, that the M140 restist up to 2300 mA
