Making a portable turntable portable
This question is definitely burning an I hope everyone can help out. I have a couple of portable turntables but only one is actually portable. They can all be plugged into the wall but only one can be powered by 6 "D" batteries.
The mission is to convert/adapt one of the plug only ones to run off batteries. They are about AC 117v-120v/5.5w-6w.
Is this as easy as soldering a + and - cable from a diy battery compartment to the circuit board. Or will something be needed in between the batteries and the board to make the power acceptable?
Also how about adapting it to take a Li-Ion(or similar) battery that could charge when it's plugged in? This sounds like it would be more complicated though. Just getting one to run on batteries would be grand.
Thanks for any and all info.
