i made a box for to cr123 but i only have one for now its for my blu-ray diode thats going in a box style type just woundering if it would work or would i need to do any thing else to it ?
I started out with 2 CR123 driving through a 7805 reg, I just got a glimmer.
RCR123's with same circuit works well (7.2v). If you are going for the LM317 reg you will, as stated already, need 9v and the PP3 is ideal.
