AA and AAA “Free” Battery Hacks

Two hacks on batteries surfaced recently. One on AA battery and the other one on AAA battery.
Personal Finance Advice discovers all disposable cameras have a battery (usually AA battery) in them which are there for powering the flash. Most of the time, when you take your disposable camera to develop your firm, the store will open the camera, get the film and throw it away. So it is possible to ask those stores that develop firm to save those unused batteries for you.

Axe Collector shows how you can rip those 9 volts battery apart and grab those battery cells inside and used as AAA batteries
– Why I Never Pay For “AAA” Batteries
A bit of caution is required with taking apart a disposable camera. While the voltage in a couple of AA’s isn’t nornally enough to hurt you, the flash in a disposable camera relies on a capaciter just like any other flash. It builds a charge from the batteries and a fully charged capaciter in a disposable camera will give you a very serious jolt, probably not enough to kill you, but certainly enough to burn your fingers and possibly even knock you out.
When I was a kid, I used to take apart those disposable cameras and use the capacitor like an arc-welder. It will knock a chunk out of a screwdriver tip. Pretty cool considering you don’t have to design the circuit or pay any extra for this feature. All you have to do is wait a few seconds and it is charged and ready to go again. :)
Why should we each have our own cloud versus letting the device receive push requests from newly enabled push services? Because not every service we use is going to be push enabled over night. Adoption is always slow, and there will be some sites that never even make the switch. Having one central location, in the cloud, that we can all log into to manage our information flow just seems like the right way to go forward.
