ok so I'm gonna build my first laser using a PHR-803T diode.
I got the host coverd (with heatsink) but now I got some problems with the driver and battery's to use.
From what I can gather from this site I need about 9V input to make the everything work. It will be build using this schematic:
giving me a max current of about 125 mA
Am I right about all this? if yes then I can start building this part.
Now for the second question: What battery's can I use to power this? My host can hold 3 AAA battery's but I doubt if I can find those at higher voltages then 1.5V. I've seen other people power this diode with 2 14500's but that will only give 7.4 V total so how can this ever be enough to run a PHR-803T diode from? (I can probably modify the host battery holder to hold 2 AA's)
Thanks in advance Warzon3
