Well considering that's like 10 times the cost of an el-cheapo... |

If you do try to hack in a power supply make sure you test the voltage. Many of the wall warts run high without load so a 3V PS could run at 6V or higher. If you find one that is regulated this should be ok. I think some cell phone chargers run at 2.8 or 3V those should work. Hmmm...I wonder if you could take some of the 5V from a USB port? Any way to cut this in half? |
| BobA:
3 diodes in series with the 5v will cut the voltage down to 3 v. The diodes have to be able to carry the load of the unit being powered so 1n4001 to 1n4004s work well as they can carry 1 amp. +5V supply >| >| >| unit being powered Gnd or Return 0.7 0.7 0.7 2.9V |
| MinerAl:
Find one of the el-cheapo ones that plug into the car cigarette lighter. It should be really easy to get 12V (either from your PC or a wall-wart) to run it. |

This piqued my interest so i did a quick search. Found there are some usb-powered fm transmitters out there. The following are not really 'el-cheapo' though (range from $30 to $90). Don't know if this helps - just throwin it out there. As already posted, it would be a cheap hack to a wall adaptor or usb plug or something for what you already have. New toys are fun though. LineX nexxtech Relatively cheap. Read the reviews - sounds pretty good. wholehouse sww This SoundWithoutWires one sounds ok for the cash. See this old info before ordering direct though: sww_mp3car |
