i need to find a coin meter or a card meter where i can take the insides out and make into a fake meter to take the money for the lights on halloween to work, ill be monitoring the drive throughout the event so will make the show happen from the computer manually when people put the money in the box say 50 pence to see the lights dance to music all proceeds will be sent to chosen chairty etc etc has anyone either got an old coin operated meter they are willing to give away postage would be paid obvously. or do they know where i could get one from, also if ots a coin version does it need to have 240 volts to light a lamp up upstairs in the house or could i run 12 v dc through it instead, many thanks in advance.
