Just checking in, reporting my Twine plans
Just dropping a line here to a) say hi and b) report my plans for my newly-obtained Twine.
After a fire/smoke scare at my apartment last year (thanks, idiot neighbor) I got to wondering why there aren't any smoke detectors on the market capable of email/SMS/tweeting when they go off. Some googling on this basically turned up nothing. Some folks I spoke to swear these exist in China, but I've been unable to locate any so far.
So: the plan is to
a) Cannibalize an existing smoke detector
b) Measure the voltage inbound to its piezo alarm when it goes off
c) Hit radio shack for whatever I need to interface that with the Twine breakout
d) Add another 2 x AAA's in parallel
... and a rule that Tweets me: THE ROOF, THE ROOF, THE ROOF IS ON FIRE if the smoke alarm ever goes off.
standard disclaimer: yeah I know, not using this for safety/critical uses, etc. Just an easy first experiment for my twine.
Thanks - you just inspired me to hook a break out board up to the output on my house alarm. I hadn't thought of anything like this before reading your post.
