I was tired of having to get on and off my bike to open and close the garage door each time I headed out. While my wife and I were out of town we found a project at a dealer that allowed you to operate the garage door via the hi-beam switch. It was $120 and more than we wanted to spend at the time (times two since we'd each want one on our bike). Recently, however, I decided, "how hard could it be to come up with a simple circuit to trip the garage door opener from an existing circuit on the bike"? The first one took a few hours of research, building, and a bit of trial and error. This instructable includes the step-by-step instructions I used for our second bike to put it together in under an hour for $15 plus a garage door opener.
Step 1: Parts Needed
Here are the parts needed (Radio Shack mode # in parentheses):
- 12VDC/125VAC 10A SPDT Mini Relay (275-248)
- 1000 microfarad 35V 20% Radial-lead Electrolytic Capacitor (272-1032)
- 10K ohm 1/2W 5% Carbon Film Resistor pk/5 (271-1126)
- Project Enclosure - 4x2x1" (270-1802)
In addition, you'll need a garage door opener. I used a Chamberlain Universal Garage Door Opener that I found at Lowes.
For a nice, clean installation, I'd pick up some 18g hook-up wire, heat shrink tubing, and some wire-tap-in's. You'll also need a soldering iron and solder for making the connections.
