    SUCCESS!

    After days of research and getting down voted on a snobby Electrical Engineering forum for "not asking a proper question"..pfft... I got the IR LEDS working with the 9V battery.

    Found a wonderful site that does all the calculations for finding resistance when working with LEDs AND gives a diagram in your preferred format, if your a NOOB to electronics like me check it out:

    SQUEEEEE!!!!!!!!!!!

    Now I can work on setting up the pi with the camera and LCD and design the enclosure. Stay tuned!

    Hours of researching the best way to wire up my IR LEDs. Seems like parallel is best. But Ive never used a breadboard and mucked it all up somehow.

    My resistor value is correct I think:

    V=9

    I=100

    R=10 (with voltage drop of 1.5V over 9 LEDs)

    Nothing happened, used my handy multimeter to check power was coming in.

    Somehow fried 8 LEDs!!!! oh the humanity!!.....unless they never worked, but I got them from Adafruit so Im sure they were legit.

    I'll have to begin with a fresh brain tomorrow and just wine about it tonight.

    Project log 0001:

    Forgot I had superglued the LCD on a piece of plexiglass, ill have to take a look at my solvents.

    Also didnt take into consideration that the LCD requires power, maybe there is a way to combine it with the PI??? If not I have and extra battery pack that came in a case of beer.

    The future is meow!
