If your house gets a lot of wind, (let’s say for example you live near the beach) you might benefit from installing these 400-watt wind generators to power your 12V garden gadgets.
For do-it-yourselfers, this is a perfect wind generator to get started on re-using the free wind power that’s floating around your home.
I wonder why golf cart manufacturers never thought of a sustainable solar powered golf cart like this in the first place. The great thing about these solar carts is that they will re-charge themselves most likely during the round of golf so you never really have to re-charge them via a wall-plug.
The Solar Powered Golf Cart. This is the electric golf cart that has an array of 72 photovoltaic cells built into the roof that collect solar energy, providing up to 33% more range between recharges than non-solar electric golf carts. The carts 160-wat

Remember my post on how to make a DC Welder powered by a golf cart? Well, these guys must be golfers and must own a golf course. (or at least work at a golf course.)
Now, they figured out a way to power their batteries with a big solar panel on top of the golf cart. Now the question is, can you

Here’s a cool way you can make a DC welder powered by a golf cart! Of course, you don’t have to use a golf cart but it is creative the way this guy did it.
Here’s the simplest welder you can make. It’s just a pair of jumper cables and a welding rod. Oh yeah. And some batteries to power it. I happened to have some nice juicy batteries in the form of a Golf Cart.
Check out this cool little hack, it’s an open-source motor controller for an electric bike. There’s no pictures of a finished version but can’t wait to see this circuit in action!
n brief the PicOx is a PicAxe 08M based digital Controller that performs an ADC of a Hall-effect throttle and an ADC of a Hall-based current sensor. These two parameters determine the “Mark” value of a 15Khz PWM signal that does the swit

Oh, check out this cool DIY on how to build an inexpensive Hall Effect Gaussmeter! If you don’t want to build one, you can always buy a gaussmeter here.
Have you ever wanted to find out how strong a magnet really was, or how the strength of the magnetic field varied as you changed the distance from the magnet or the temperature of the magnet, or how well a shield placed
