can i use a 12 volt battery on a 9 volt device ?
My friends dad is building a Tardis for his grandson.
We have rigged up the blue flashing light using a 12 volt car battery, we now need to sort out the sounds. I was thinking of using an old cars cassette tape, but I have an old 9 volt portable cassette handy. Will it burn down the TARDIS if I use that instead ? tafankuverymuch |
