Well at least they provided working goggles .. unlike many other shops.

I tried to get some local but struck out, I didn't know that I had to get some until I got that message that it only came with a charge.
I just tracked my batts and it says that they are out for delivery.:san:
I just wish that there was someone local that had an lpm.
Hi,
Have you find battery for your laser?
Have you tested it , it's OK ?
My unit is at the post office, I have also to wait for battery!
Thanks
Hi,
You are very happy with your 445nm lvyilaser 1 W , you want more power :
Please take a look on driver board :

Have you actually tried this yourself or is this just
experimental theory...:thinking:
Jerry
I'm not sure you should be advising people to try an experimental procedure, which could irreplebly damage thier laser.. :tsk:
especially if you havent tried it yourself
What's going on here? Is someone using Jerry's photos in another thread, with an identical thread title?
Review of $170.00 445nm Lvyi Electronics Laser
The thread title is the same, and I'm pretty sure at least one of those pictures is identical to Jerry's. Also, the review is outlined with the same section headings.
Also, I feel like Jerry's posts normally have a space between every line. (Sad that I notice that).
Something is weird Jerry, not going to lie. If its nothing, than whatever. Just kind of had a double take when I saw this thread.
Hi Jerry,
Unfortunately I haven't tried yet, 27uH and 4 x 0.33Ω CMS are waiting for shipping. BUT it is not an experimental therory, that's a prescription by the conceptor of the PT4115 CI (PowTech). please take a look at >>

With middle value like on the lvyilaser driver L= 47uH, Rcs=0.13Ω (lvyi = 0.101Ω = 5x 0.51Ω prallel) , the output current with 1 Diode will be around 720mA with 7.5V battery

But if you change for L= 27uH and Rcs=0.0825ohm (4X 0.33Ω prallel), your output current with 1 Diode will be more than 1100mA with 7.5V battery

P.S. : with 2 battery 3.6V/3.7V full charged you DC will be more 7.5 v
A+
