5 Volts batery suplay made of 4 ni-mh baterys conected in serial,I have add the switch and conector from old 9volt batery.
Few notes on this: in 4th pic "-5V" and "5V". You actually ment "0V" or "GND" and "5V"?... Voltage of this battery pack can be from little over four to almost six volts -> It'll be about 5V, but users should remember that isn't regulated. That might sound like I don't like this, but that's not true. Seems like good enclosure (Is that made out of pipe and other stuff or some kind of bottle/can?), power led... And those 9v connectors are really great. Can't get cheaper connectors than free connectors :P What kind of charger do you use (homemade or commercial)?
athat is 5volt and GND,and for charger I use homemade. regards maco
