Automatic Cut Off

can some one please help me figure out how to design a battery charger that automaticly cuts off at a....?

certian voltage. i have some expeirence with electronics and designing them so dont be afraid to speak geek lol. but i need to design a simple automatic battery tricle charger i will be chargeing a 12 volt sealed lead acid 5 AH for 1HR used for home made emergency lighting system i need it to charge the battery then at a certian voltage automaticly cut off then start a charge small enough to keep the battery full but not overcharged

There's a whole lot of knowledge embedded into modern microprocessor-controlled battery chargers, even simple ones. There's no way an individual can replicate that. I've built lots of homebrew electronics in my time, but I can recognize when it's not worth the effort, or even when no amount of my effort in my lifetime will do as well as what I can buy, probably for less than the cost of replacing the battery after one goof fries it.

Five Reasons to Consider the MBM DestroyIt 2403 Cross Cut Shredder

The DestroyIt 2403 Cross Cut Shredder gives you a high level of document security with desk-side convenience. If you are looking for a deskside shredder with a lot of power and security to spare, here are a few great reasons that you should check out the DestroyIt 2403 today.

1. High Security. The 2403 gives you a level of document shredding security that offers you piece of mind at your fingertips. As cross cut shredder that destroys documents at a Security Level of 4, the 2403 exceeds the level of security that is mandated by recently passed FACTA laws intended to stem the rising tide of Identity Theft and other types of fraud. If your business regularly handles and discards documents that contain the confidential financial information (such as SSNs and credit card numbers) of your clients and/ or employees, you are required to discard such information in such a way that it can't be read by anyone. Not doing so can leave you subject to fines and/or lawsuits, so the 2403 is a great way to not only protect your customers and employees, it can protect your business as well.
2. Desk-side Powerhouse. The 2403 gives you a lot of power in a smaller package. The powerful single-phase .75 horsepower motor offers you the ability to shred up to 11 sheets of paper at a time which is pretty impressive for a high security shredder. The high quality steel cutting shafts eat right through paper clips, staples and credit cards, and are guaranteed for the life of the shredder. DestroyIt certainly has a lot of faith in the quality of this machine.
3. Easy to Operate. The large, multi-function control button uses integrated optics to let you know what the machine's operational status is at all times. Plus, it also features a photo cell enabled automatic on and off function that lets you set the machine up for easy "walk away" operation. The shred bin is a large 9 plus gallons, and is easy to empty, and the bags are reusable which great for saving both money and the environment. The heavy duty rolling casters make this machine a breeze to move about the office as well.
4. Silent Shredding. If there's anything an office doesn't need, it's a loud machine causing distractions whenever it is used. The 2403 solves that problem with its remarkably quiet operation, which is especially enhanced by the high quality wood construction of the cabinet which helps to absorb sound and keep vibrations to a minimum.
5. Safety Features. The 2403 goes all out when it comes to safety features, with Destroyit's "SPS" or Safety Protection System. The first thing you'll find is that there's an electronically operated, transparent safety shield located in the feed opening to keep objects such as hands and clothing far away from the cutting heads. There's also a handy auto reverse function as well as a cutoff of power if there is ever a paper jam. And, to keep you safe when you are emptying or otherwise maintaining the machine, the power automatically cuts whenever the bin is full, or if the door to the cabinet open for any reason.
