Fresh hacks every day
[Glenn] from The Back Shed has built a lot of windmills and stationary generators over the years, but recently decided to try his hand at building something a bit more portable.
The charger is based of a relatively simple design, employing a 5.2 HP Kubota 4 stroke motor and a 12v car alternator to provide power. While you might be … Read the rest
Reader [Andre] sent in a link which tells us all about this “cool” Copper Oxide Thermoelectric Generator. All you need is a bit of solid copper wire and a gas torch. Burn the wire so it gets a nice coating of oxide. From there, it is a matter of making the 2 sections of burned wire cross at a … Read the rest
We’ve all heard of solar cells that charge your devices, or the odd flashlight that charges when you shake it, but this style charger should be new to almost everyone. This “pan charger” is reportedly capable of charging a cell phone or other mobile device using a USB connection in 3 to 5 hours. It also has a built-in radio … Read the rest
You can build a copy of this vertical wind turbine in a weekend and it won’t cost you all that much. Applied Sciences developed the hardware and they’re sharing all for the build details. You will be taken through every part of the build starting with the fin assembly which is made from stove-pipe material. This is a perfect … Read the rest
[Ben Nelson] turned his electric Geo Metro into a plug-in hybrid. But wait, where’d he get an electric Geo Metro? It seems that we’re one hack behind [Ben], who converted the vehicle to all electric back in 2008 using a forklift motor and some batteries. This time around he’s following the Chevrolet Volt’s example by adding a backup generator. … Read the rest
[Scott Nietfeld] built a charger from a Dyna-flex wrist exerciser. We hadn’t heard of a these gyroscopic devices before but once we saw the promo video (embedded after the break) we realized that this is the kind of thing that infomercials were made to sell. [Scott] knew the internals spun to fairly high RPM and figured that adding a few … Read the rest
What weighs more than 500 pounds, produces 500 kilovolts, and we don’t recommend you try at home in any way shape or form? If you guessed a rock disaggregation device, you’re correct! We also accepted lightning generators as correct answers. Using high voltage electricity, a rock can be split apart down to its grains without destroying the precious … Read the rest
