Hmmm ...
4xAA would have to go in a 2x2 block (pair of 2xAA holders back-to-back?) to fit in the space. I've seen several tiny circuits for the Linear Regulator, including the linked one, so I can go with that (if my failing eyes and shaky hands can cope with the soldering!).
I'll talk to my PCB man about the best way to design it, as he'll be the one etching it!
So that is power.
Back to Audio, then. I've got a LM386 and a few other bits on the way, to build the circuit from.
I can just connect this to the 6V battery feed?
I'll draw up a full schematic at some point! I've been testing parts, and building it bit by bit on breadboard, and now designing the PCB(s).
Should really document the whole plan!
Guess I'm procrastinating a little - the physical preparation of the Tank is going to be a bind! I've drilled a few LED holes, and when I've got them all done, I need to paint it before installing the Gubbins. Bleeuurrgghh!
Will post a few pics as I progress, but not much to see for now.
If nothing else, I've already learnt LOTS (some for the second time, but long-forgotten! ) Thanks!
