| How Can I Drop DC Voltage? |
| (1/3) > >> |

I'm currently hacking 3 Jakks handheld games into a cabinet (see the project HERE). The AC to DC converters I have are outputting 7.2 volts with a load applied. I assume that I can put something (resistor, transistor, diode - don't laugh I'm not an electrical engineer) in line that will drop the voltage to 6v. Can anybody tell me specifically what I need to drop DC voltage 1 volt and how to wire it in? |

A resistor will do it. One easy way would be to use a potentiometer. You could hook it up to a volt meter and turn the knob until you were at your desired voltage. |

The even easier way would be just to get a selectable voltage power supply from Radio Shack. |

I can't believe how innacurate these things are. I was blown away when I set in on 6v and it ouput 9 volts. I went to Radioshack and bought a dedicated 6v unit. I had the clerk meter it and it came out 7.8 volts. Even with a load it's still hot. Luckily it hasn't fried my handhelds, but the video signal seems a little hot. I wouldn't think that would matter, but it apparently does. |
