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 this cool huge bicycle that’d be good for some street advertisement of zedomax.com (not…actually we’ve been thinking of making some free T-shirts to give out to beggars around San Francisco downtown area so we can help some people while getting some advertisement…well…)

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

One of the characteristics of a successful natural interface is the reduction of cognitive load on people interacting with it: from a presentation perspective, the form of the representation of content is designed to minimize this amount, by reducing the number and the complexity of the stimuli, and allowing a straightforward interpretation of the whole perceived by the subject; from an interaction perspective, this is done by allowing people
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.

Yes, one of my personal goal in life is to own a boat some day but here’s how you can make one from scratch!
I was looking for a double ended rowing / sailing beach cruiser that two people could use for extended camping in semi protected waters. Ben Fuller brought this design to my attention. The boat is similar to a Swampscott dory but carries a bit more waterline, a rockered keel, a fuller hull section, and an external skeg. The boat f
Most digital cameras support panoramic support but if you like antiques and retro-gadgets, you might want to take a look at this cool panoramic pinhole camera! It seems like he hacked a pin-hole camera to take panoramic pictures.
