I bought an alarm for my motorbike.
I installed it and was happy with it… for two days.
The device slowly (2 days) drained the battery down.
The only option to keep the alarm seemed to be connecting a treacle charger to the battery. (and to buy a long enough cable that reaches from my garage to work at least)
Then I was also thinking about a solar panel to resolve this… but that doesn’t give enough juice. (measured it)
Despite studying electronics for years I took a deep breath and contacted professionals to help.
I secretly hoped they will try to sell me an alarm that costs [̲̅$̲̅(̲̅xxxx)̲̅$̲̅]
because I have to admit, the alarm I had was a Chinese .
Their best advice was… buy a bigger bike that fits a stronger battery, but not so sophisticatedly:
-AMPERHOUR, mate, that’s what you need!
I was fuming so started to look for alternative solutions… without much success.
I had to realise that small cc bikes need to be chained down at least.
Anyways, to solve the issue I thought I could just include a switch that could turn off the alarm and VOILÁ… case closed! Unless it isn’t!
MY GENIUS EQUATION WAS MISSING THE LOCK ITSELF!
Me being a silly pickle thinking that switching off the alarm would be good idea, huh??!!
The reason I'm going into the story is to tell what the project is NOT GOOD FOR btw. Stay tuned, I get to the point:
I didn’t give up! I thought about including a reed switch as circuit breaker and came up with a design:
The ping pong bat rotated counterclockwise meant to represent the antenna.
The loaf of bread under the reader is a reed switch.
The big red question mark would be the lock itself. It has to be mechanic to save power.
Plus on top, ground on bottom.
The other doodles on the picture are another implant with an extra LED.
Why would it be good, apart from a long lasting battery?
It would be useful for things that are small, or you need to save weight, like in the case of a suitcase. The surface of the lagguage could be smooth from the outside (continuous), no keyholes or code locks to attack.
I am unlikely to be the person who designs a gun or a suitcase, these are just ideas.
…that’s about it.
