Hi All,
I must have had my watch set to a day earlier, Earth Day was yesterday but I figured 1 day late is never too late for eco-friendly gadgets.
So here’s a round-up of various different eco-friendly and green gadgets you can buy to save the world:
Solar Alarm Clock – Great stuff, they should make all alarm clocks with a solar panel. How hard is that? Probably not that hard, look at all the caculators made today, the
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 switching to the Outp
The other day, my home had power-outage for like 6 hours. I could go buy a UPS (Uninterruptible Power Supply), or I can make my own UPS using a car battery.
Well, I am just hoping this DIY UPS lasts 6 hours so I can keep using my spare laptop, which shouldn’t need that much power anyways to run off the UPS. But if I tried to run my desktop PC, it’d p

Here’s a funny hack using a cellphone, wires, and a 16pF capacitor.
Take one SonyEricsson K800i, rewire the capacitor (which feeds the camera flash) with a pair of 16uf caps and you have a cell phone capable of dumping those farads into a human body. Just take a photo using the camera’s xenon flash and shoot.
If you can’t read the multimeter in murk of what looks like a typical teenager’s bedroom, it shows 300 volts. Cameron20020, the video’s creator, describes it thus:
“…while
Check out this really cool parts organizer you can make using plastic bottles and save the earth at the same time!
If you’re like me, you have a ton of PCBs laying around from things you’ve taken apart. Put them to good use and salvage the components from them.

Ever thought of turning electrical waves floating in the air into electricity? Well, here a guide if you need it.
This is btw, similar to the new “wireless” batteries that Phillips is working on. (i think it’s phillips…)
Wow, this is something that could really change the world!
Advances in biomechanical engineering could use energy generated while walking, hiking or running to power any device requiring portable power, including night-vision goggles and other battery-operated devices used by soldiers as well as robotic prosthetic limbs, cell phones and computers in remote locations where no other energy sources are available.
Cool, this guy’s on TV for tryin’ to build a nuclear reactor. Too bad he didn’t have a SiteHoppin.com shirt on… :p
Apparently bored of his amateur game-building hobby, he decided to try to make a small-scale nuclear reaction in his room, blogging his antics on the web.
Someone blew the whistle on him when he made claims about uranium and doubling the normal background radiation count in his room, and the Nuclear Regulatory Commission raided his home. He won’t be getting his Da
