I was surfing around and found a site that sells mannequins attached to a hand truck moving a sign. You know the type to help attract attention to a business. Here's the site: http://www.signwavingrobot.com/economy.html
Anywho, I got the idea to build a few props and run them off of batteries to avoid the need for an extension cord. This is only for some specific locations where cords are an issue or mobility is desired. So my question is, has anyone else done this and if so, what kind of battery worked best? A marine battery or ... ?
I was able to track down the battery charger that they use on pic 28 of the above link. Here is a direct link to purchase the charger : http://www.batterystuff.com/battery-chargers/energizer-12-volt-2-amp-battery-charger-e-1202.html
There are other sources for these things but I just posted the first ones that I found. According to the Sign/Robot site a 6-hour charge will run the prop for 20 hours! That's the line that got me excited. So what are your thoughts on battery types? If I can find a smaller, lighter, cheaper battery that will run for 8 to 10 hours that would be great! And not have to deal with the expense and weight of a car battery.
