Introduction: Rc/d Almost Anything
This is an easy project for someone with minimal skill, or even highly skilled, but I made it with minimal skill. I used a battery powered doorbell to make almost anything rc/d. First you have to use a multimeter to find the ground spot and the power wireI used a small npn transistor to act as a relay. From there i bumped up the voltage ability by using a 5 volt relay. The schematic shows it all except the on off switch, which is put between the power source and the relay. Overall the project cost around $20. After you have it all put together, you can just use it as a switch, the only downside to it is that the swich is on for only a few seconds. I have only one use right now, i hook up a siren from radioshack and scare the crap out of people with it. I hope you like it
