Well, the situation is the following.
I have successfully built my touch panel device, mounting a TFT LCD over a perfboard where I put a PIC controlling it and some I/O such as LEDs and switches. It looks very neat and portable (I can hold it in my hand)
The thing is, so far in my projects I am using power from ...um I dont know what is the correct name... power devices? manufactured by COSEL. I have to connect it to a power outlet (AC), this transforms it into my required 5V (although the whole system is 3.3V, the LCD transforms this from 5V as an option- it can also receive 3.3V).
But my device seems so portable that I would love to have a portable power for it too (and free it from connecting to a power outlet). What I need is a battery of some sort.
Before I used to use batteries, and tried to get 5V from say 4 1.5V batteries but that gives 6V and although it worked to some extent I was scolded...
So my question is what is the Correct way to get this 5V (or 3.3V if that is the case) to power my device??
Thanks for your expert advice
