Presale for C6 JAD kits.

[Mohrenberg]

I received Aurora C6 JAD kit with 1.8A round driver. Why the driver produces 7.4 volts with 2x 16340 batteries at the output ? It's too much for the laser.

I'm guessing you're the one with the PayPal claim against me for non-delivery? Being as you're from saratov, russia?

Laser diodes are not driven by voltage, but by current. You just need a minimum voltage, and after you reach that minimum, it doesn't really matter.


Your diode isn't dead if it's bright for the first second or two. That sounds more like a battery problem.
Make sure both the batteries are fully charged.

The 16340's you have probably can't handle the current draw. Get these batteries:

Sorry for PayPal claim, i closed it today, I just thought that my parcel lost, and I have to return my money. But today i received a parcel (after 40 days of delivery, thank you shitty Russian mail) , thanks for very high quality kit I hope it is just problem with batteries.

Today I tried turn on laser with charged batteries, the problem is the same. When I turn on the laser, it shines very brightly about half a second, but after a few seconds laser begins to shine as a normal blue LED and becomes very hot. I'm guessing that the problem with too much voltage at the output of the driver - 8V with charged batteries (measured with a voltmeter).
P.S.
1st photo - just turned on laser
2nd photo - after 1 sec
P.S.S
And why do you reduce my reputation because I opened a paypal disputes ? First time I ordering something from America, I did not think that the parcel delivery will take so much time, I will not open the disputes again. I'm sorry for those disputes which I opened. :angel:

I don't see a photo. We need to see clear pictures of the inside and how the wires are connected.

 

[Flashrazor]

Added photos of the wires connection. The main question is why the laser produces so little light and becomes very hot.

 

[Blord]

The wires looks okay. Without a testload you can't do much about it.
That is a M140/H1600 diode for sure, nice close-up.
