Does anybody know of a good backpacker's alarm clock that is loud and still weighs less than an ounce?
I wear a wristwatch with an alarm mode, but when it is on my wrist inside a sleeping bag, I never hear it. I have a small alarm clock that weighs slightly over one ounce, and it is OK. I tie it onto my tarp's front pole, so the alarm sound will be within a foot of my ears.
Part of the problem is that in order for an alarm clock to have a loud sound, it often has to have a big power source, bigger than one AAA battery, and that will likely put it over the one ounce mark right there. Smaller alarm clocks get by with a "watch battery" to get a lighter weight, but the sound isn't normally so loud.
