Firstly, let me say this is a pretty cool place, and I wish I wasn't just wondering on, asking for advice, and wondering off. My specialisation is 2 wheelers and engineering, though, not electronics, and whilst I have a better understanding than the general public, I quickly get lost when long words are banded about so I wouldn't be much of an asset!
What I'm looking at doing is to annoy anyone attempting to nick my motorbike. The basic principle will be a hidden switch, somewhere, that controls whether the "start" button* activates the horn for ~30 seconds (using a separate battery so the bike will still start when I get back!) or starts the bike. I found a thread here which is a similar project to mine, but doesn't have the 30 second stipulation, and so will run the battery flat... great! On mine, the plan is the horn can be disabled either with another hidden switch (If I/a friend activates it accidentally) or will turn off automatically after 30 seconds, but can then be re-activated immediately if the scummy thieves are still mad enough to be trying their luck. Any suggestions? And please avoid using long words
*Would it be a fair bet that this start button is carrying a very small current to a relay, rather than carrying the full brunt of the power for the starter motor?
Many thanks!
