I hate my camera, it takes very poor quality images despite being 12MP
Either the light is too dark or the flash is too bright.
So, I have decided to use my Pi0 and some scrap melamine particleboard to create a sort of box where I can control the lighting conditions.
I settled on using five 3535 SMD LEDs
Which I'll buy from here: https://au.rs-online.com/mobile/p/visible-leds/8140866/
I intend to recycle a disused 12v, 1.5A SMPS to power the LEDs and the Pi (with a buck converter between)
I used an online calculator to determine the best way to place the LEDs and it has given me the following result:
I am a little concerned with the warning it gave me. I don't fully understand the data so don't know what the implications are.
Will it just get excessively hot? I have heaps of aluminium to construct heatpipes and such.
Mostly though, I am concerned about efficiency and the LEDs stated forward voltage. The datasheet says 5.8v minimum, 6.1v typical, 6.8v maximum.
My experience with LEDs is limited to some wires and a battery that equals the total forward voltage, so I don't understand much about resistors and diodes in general.
Can anybody explain this message and of course, how should I control this from the Pi?
