Here’s a cool little project that stores data into an SD card using solar power.
After some prodding from customers and an upcoming prototype run I decided to throw in a little breakout board that would allow 2 solar panels to be connected in parallel to a 7805 linear regulator. An LED was added with a switch so the user could identify when the board was making power. These boards can output 8V@300 mA and should easily provide more than enough votage and current to charge the batt
Check out this cool DIY you can make some cheap high voltage. I’ve always wanted to do this at a low cost but here it is!
What you see here is a spent propane torch tank with a 1-inch (2.5cm) ball bearing glued to it with a 1/4-inch (6mm) bearing glued to that. I stripped the propane tank with paint stripper, but this is unnecessary as you can just scrape off the paint where the ball bearings go. The Leyden jar is just a common quart sized polyethylene bottle cut off at the top. The
Check out how you can build your own solar cooker using an old satellite dish!
The basic idea was to use a satellite dish and rivet sheet aluminum to it. This is because a satellite dish is already a paraboloid shape with a pretty exact focus. The sheet aluminum was to be cut into triangular pieces and then be drilled in 3-5 places for the rivets. They would conform to the shape of the paraboloid and not lessen the integrity of the focal point. We wanted the

Make’s going to try to send a balloon to space! This is a great idea for anyone who’s trying to get something out on the outer space without using a big industrial rocket. Get PDF Here.
We’re using weather balloons to go up to approximately 100k feet armed with 4 cameras… 20 megapixels of camera! We’ll be taking shots every 7 seconds for two hours and measuring the temperature with the Make: controller and therm
Here’s a cool DIY on how to make paper using some household materials.
Gather what you need. Most things are household items, except for the screen and the vat. It goes easier if you work near a water source, and where you can spill water without worries.

Here’s H2O to HHO hydrogen technology being developed by 2 guys which might change the world soon…
Thanks gfcgamer!
Ooooohhhh, check this out if you are into making alternative energy.
This is my project to make a semi compact wind turbine that can handle turbulant wind and generate enough power to charge deep cycle batteries. I will cover the rotor construction in the instructable. You will need to download my PDF for the whole project.

Here’s a cool video of car running on water. What do you think? Thanks gfcgamer!
Here’s also a conversion-kit guide you can buy.
Here’s a fun kit that will allow you to make energy from air by combining hydrogen and oxygen!
The Exhibition Set is the ideal model for demonstrating renewable hydrogen energy technology to large groups, in classrooms, at trade shows or in the boardroom. Clearly labeled components and gas tubes make the Exhibition Set simple to operate and easy for your target audience to understand. The unit was designed specifically for extended, unsupervis
Check out this hamster-ball for humans. You could probably use it as a shield or something and use it as a personal “mobile” device at the same time.
