Once you have the correct voltage going to the device, the internal resistance of the components inside will determine how much current is drawn. If the battery can provide that much current, you should be good to go. We'd all like to know what you're trying to power ;) http://webhome.idirect.com/~jadams/electronics/series.htm This provides a decent explanation... --- End quote --- Using resistors to divide voltage will only work if you are trying to supply voltage to a circuit that doesn't draw any current. For all other cases, the resistance of the device that you hook up will be in parallel with one of the resistors in your voltage divider -- the voltage division across the resistors will change. Don't take this correction as a slam against you ... I don't want BOYACr's to be misinformed. In case you are wondering, I am an electrical engineer (Lawrence Technological University, BSEE 1991). |

Check out this site. This guy has used Sony camcorder batteries to power a portable atari 2600 he's designed (VERY slick). I think you can find some usefull info here. http://www.classicgaming.com/vcsp/ |

I guess I should stick to DSP applications... Im on my way to BSEE-- graduating at the end of this school year. :) |

Jakobud, Why do you want to power it with the camcorder battery? If the reason is because the camcorder battery is rechargable why not buy some Ni-MH AA batteries and a charger? Once you have these you won't have to buy AAs for a very long time. |
