As Tom said, Radio Shack should be able to provide you what you need. I take probe testers for 12 volt DC and cut the ground line. In the line I take a kit box and solder together a 3 to 28 volt buzzer. One I bought actually beeped as power was applied. It would work great. If you know where to tap for the reverse current, you could epoxy the beeper to the bottom of the truck. ----- Original Message ----- From: David Engebretson Jr. To: [email protected] Sent: Wednesday, February 11, 2009 6:50 PM Subject: [BlindHandyMan] back up sounds
I have a 2 year old who really wants to add back up noises to his remote controlled dump truck. I was thinking, as an electronics engineer, that I could tap into the power from the batteries and add some kind of circuit to make a little beep beep while in reverse. Then I thought there is probably already such a device on the market for real cars.although it probably runs off of 12 volts for a real car. This has 4 C cells in it. Anybody have any ideas for us as to how to make it go beep when it is in reverse? Thanks, David [Non-text portions of this message have been removed] [Non-text portions of this message have been removed]
