It's finally finished!
A dual Sharp GH04850B2G diode running on a simple lm317t circuit, powered by 2 18350 cells, outputting 60mw at 487nm, and when switched to the secondary boost driver, it is driven 12.5+ volts at @450ma which results in enormous wavelength shift at 493nm and 180mw of power.

The wavelength color is calculated through a diffraction grating calibrated with 532nm green so it might not perfect but the difference is really obvious (not that well for the camera though).

Also the output power is measured by an lpfstore power meter so I removed approximately 10% from the readings I got.

Here it is compared to another 491nm laser build running with a boost driver from @Giannis_TDM at 100mw
First to the left with low power 487nm and to the right full power on 493nm switch

Ik the dual alternation switch is kinda ghetto and pointy but I couldn't find a dual wiring button one:(


Ps: I'm member here from 2010 but I completely forgot my passwords so i made a new account
