Hi everyone.
Nice to see a forum like this.
Newly registered, and still reading up on lasers and drivers.
I've got a question about voltage för this module.
Its driven by an ac adapter 230v > 5v DC, 1000ma
I disconnected the plus wiring and took a voltage measurement
When the diode is hooked up, it reads about 12v.
300mA.
Its also got a red one. But not interested. =')
Obviously a boost circuit here, but as soon as I disconnect the diode and go against the connector pins on the board it reads about 3.1V output.
Can someone give me a quick explanation on this type of circuit?
I'd like to make a pointer out of it, get myself a good host and so on.
But I need to know how this circuit works.
I do have some bucks and boosts lying around, the generic blue ones thats sold all over Ali and so on.
So to be straightforward I could just boost either one, or better two 18650 to 12v.
I'll some pictures of the board here too.
Just for fun:
I removed the KTP and small lens (collimator I guess) and the IR diode didn't do much of a smoking against black plastic.
Hardly anything compared to my "303" green laser, to which i lost the crystal, for other reasons, burns and smokes even wood.
Seems quite powerful.
Have a nice evening.
