usb to fm transmitter Answered
I am a very big noob to wiring.
For a present, I wanted to make my cheap old AAA powered fm transmitter into a usb powered one.
Thinking I was so smart, I cut up an old usb cord and soldered the red to positive and black to negative.
It worked great until it started melting the transmitter.
So I now I realize that usb is much more powerful than 2 AAAs. heh heh.
I found this:
but it's a bit over my head. I'm assuming I need to get a capacitor or voltage divider but I could use a little help breaking it down into noob speak. Plus the transmitter is a little thing, 2 inches, is there a smaller way of checking the voltage?
K, thanks bye!
