Hello everyone,
I have a project in mind and I need some tech help to make it work and save some money while doing it.
I have a wildlife game camera, it is made by Moultrie and the model is a D-40. The camera runs from (6) D cell batteries at 1.5 volts each. The camera includes a female plug for an external battery source (D/C.) The Moultrie company sells a combo 12 volt battery and solar combo that is made specifically for this model camera, but their asking price is $90.00. I am trying to figure out how I can use a 12 volt battery and drop the voltage from 12 volts to 9 volts for the camera. I have done research and found that a LM317T is rated for 9 volts D/C, but the rating on the 3-pin is 1.5 v to 37v. My question is this, if I use this LM317T on the positive side, do I need resistors also in the circuit for D/C from 12v to 9v, and if so where should they be placed?
DISCLAIMER: My education in electronics are maxed at knowing that (+) positive is red and (-) negative is black!
