Edit, the laser is completely done now, pictures will be added today. Thanks everyone for assistance!
I got a 405nm laser diode driver (0/250mW) battery BMS (management circuit) and a safety switch soldered on a laser diode board. To turn the laser on, there is an on/off button on the rear of my host, if you push it, nothing happens due to the security switch I designed and build. Its a shock switch. To turn it on, you have to tap it against your leg vertically. This is here to trigger the BMS on. It was a problem but I got it fixed by looking at the G2JF datasheet. However, very complicated. But I got it done.
This circuit took me 5 days to design and make. I even had to put a reverse polarity protection circuit in there since the bms isn't protected against it and I already roasted 5 of them. Those where prototype circuits, this one is completed and fixed against any electrical failures
.
I also bought a 3 element glass lens for 405nm, I took it apart to make it watertight. It was hard as the lenses had to be absolutely clean, but I got it done. Took me 1 complete day.
I also ordered a 5mW red laser module as it was cheap and it has the aixiz housing. Still has to come
and I ordered a SLD3232VF Sony 405nm 50mW 70mA diode. My driver output is 6 volts, this diode is rated for 5.5 volts. This shouldn't be a problem when the current is lower then 70mA right?
The diode still has to come
And I don't have a test load or an ammeter. So next question, can I set the laser driver to its lowest output power, connecting the laser diode and SLOWLY turning the pot when I get around 20mW? I can compare it with an true 20mW 405nM pointer. And the driver has an ceramic capacitor, do I have to discharge that? And how?
This is a very complicated laser pen build. Its even gonna be watertight as this host is watertight and my lens too.resistand to drops and very stormy weathers. I never saw anything like this so small. 11mmx14mm. Host size is 12mm (drilled with an lathe by me for the laser module, and 10mm for the ICR10440 battery. Security switch so no one can operate it unless they know how to turn it on. Intergrated battery protection cicruit for shorts, over current draw and voltage drop (2.20v)
And I made a ultra small connector, making this thing easy to repair. If the diode breaks, all I have to do is unscrew the laser diode thing where it is pressed in from the main body, slam it out, soldering the wires, connect it in the socket en its working. It will cost you 5 min.
All of this in this small package. It took me some good days to engineer and design the infrastructure.
edit:
I can make more pictures if needed!!!!!! Just ask
