Once assembled, all you need is some wind.

Texenergy's Infinite Air Mini Wind Turbine

In stronger winds the Infinite Air spins up with the threatening roar of a turbo-proper plane, but it’s actually been designed to work and produce decent power in winds of from 12-15 mph upwards. ‘Moderate winds’ is the technical term and it’s what we had. Think moving grass and rustling leaves rather than cats being blown past your ears… In those conditions, the blades spun up easily and an iPhone plugged into the USB outlet was happily charging away.

For more general use and for storable power, you can charge up one of Texenergy’s own TexFlex 3 batteries, a super neat, folding, magnetic 3000mAh lithium ion pack that’ll fold into a neat cube or extend into a pocket-friendly, thin package. It’s highly water resistant too, covered in waterproof leather and features useful LED status lights. Portable Wind Turbine Makes Roughing It Easier. It’s 20 below and the sides of your Arctic Oven tent are snapping in the wind, but you have a hot cup of coffee and your laptop is juiced, thanks to the Revolver.

Portable Wind Turbine Makes Roughing It Easier

Revolver, a favorite in frog’s first internal design competition, Future or Fiction, comes across solidly future, delivering 35 watts of wind power even in the most temperate of breezes. In addition to being very lightweight, and thus portable, the prototype for this mobile energy-on-the-go is also very easy to set up. Simply attach (or unfold) the die-cast magnesium legs, push the collar on the central column (where the flexible blades are attached) up and hold it in place with (presumably) a cotter pin assembly, and you have a working wind turbine.

Portable 12 Volt 17 Watt Wind Generator with Automatic Furling. I've just designed and built a practical, portable 12 Volt 17 Watt wind generator that is ideal (and appropriate) for setting up in campgrounds, parks, Earth Day exhibitions, research stations, and third world homesteads.

Portable 12 Volt 17 Watt Wind Generator with Automatic Furling

On "light breeze" days (5mph = 2.2m/s) when most wind generators are becalmed, this light-and-nimble unit reliably generates power, at charging levels, fully taking advantage of the erratic, gusting winds that are so common in near-ground conditions. A 48VDC, 1,600 rpm brushed permanent magnet motor (#370-350-00 / PE24113G -from a medical centrifuge), with a standard keyed 5/16 inch diameter steel shaft, was used to serve as the generator. A shaft arbor, 3/8-24 right hand (Grainger Item# 3ZN05 / Dayton Item# 3ZN05) was fitted on the shaft, to use as a 12 Volt generator, @ 550 rpm, when turned clockwise.

PVC Wind Turbine Blades

The raw material, PVC pipe, is easy to find, relatively cheap, easy to work with, and performance is more than acceptable for a small basic wind turbine generator. Build your own mini wind turbine from printer parts. Here's a fun little DIY project that can bring home the clean, quiet nature of wind energy.

Build your own mini wind turbine from printer parts

For all the DIY-ers and parents and teachers who want to get hands-on with renewable energy, building a micro wind turbine could be a great little project. It's not nearly big enough to power anything large, but it could certainly be put to use as a demonstration of wind energy, and might even be worth building as a mini charging station for portable electronics or small outdoor lighting accessories. I'm a big fan of small solar chargers for keeping gadgets and gizmos charged, and while I do know that it is possible to build your own DIY version of these portable power plants, I have yet to see good plans for building one that uses scavenged or repurposed materials, so I've not done that yet.

A few more details on the project, as well as instructions for some other DIY electricity and science projects, can be found at ScienceTubeToday. Build your own mini wind turbine from printer parts. ARDUINO MPPT SOLAR CHARGE CONTROLLER (Version-3.0) After lot testing we observed that MOSFET ( Q3 ) in ver-3.0 design is burning repeatedly.We tried to modify the existing software but not find any satisfactory result.


The other problem was that MOSFET Q1 ( in V-3.0) conduct even when there is no solar input. To solve the above problems and enhance the power handling capability we are modifying both the hardware and software.This is named as Version-3.1 Charge Controller. This version is not completed yet.So wait until it is complete. Don't worry we are making a solution for those who have made the V-3.0 prototype.After little modification we will able to use the new software. You can see the updates on This version have 3 options. A Small Wind Turbine for a Big Difference by RMRDTECH.

WindPax: Portable Wind Turbines by Justin R Chambers. ARDUINO SOLAR CHARGE CONTROLLER ( Version 2.0) Parts: 1.Arduino Nano (Amazon / eBay) ARDUINO MPPT SOLAR CHARGE CONTROLLER (Version-3.0) DIY thermoelectric device charges hiker's smartphone. ( —Whether you're in a city café hunting down a spare outlet or camping and worrying about losing outside contact, the problem is the same, a smartphone about to lose power just when you need it the most. What to do? A problem-solver who is into hiking and backpacking has an answer. He shows, step to step, how to construct a portable thermoelectric emergency generator.

David Johansson, who used the project-sharing site Instructables for his step by step instructions, explained how he arrived at the idea, construction, and results. Spending several days hiking in the wild at times, he would rely on his smartphone with GPS, along with spare batteries and solar chargers. "The sun in Sweden is not very reliable," he wrote. Error loading skin: Error loading file In thinking up alternatives, he considered the idea of producing electricity from heat for USB gadgets. Float charging lithium ion cells. Apart from making better door stops, what advantage do lead-acid batteries have over lithium ion (Li-ion) batteries? The answer is that they are easier to charge. Apply 13.8V to any nominally 12V lead-acid battery and it will take just the current needed to keep itself in tip top condition, and it will be ready to deliver its full capacity instantly. Applying a constant potential is called ‘float charging’ and lead-acid batteries are almost perfectly suited to it.

While more expensive per Watt-hour, lithium-ion cells are far lighter, smaller and contain fewer toxic chemicals than most other commonly available battery types. However, for reasons of maximum capacity, charge time and safety, the algorithms recommended by Li-ion manufacturers to charge their cells are complex (see box). Hacked Gadgets – DIY Tech Blog. Deba168 from India designed and built this Arduino Solar Charge Controller to provide electrical power in areas where the grid can’t always provide power when needed.

Code and schematics are provided so you can get some inspiration from the design. ”At first the charge controller will check the solar panel voltage and compare it with battery voltage ,If it is greater then the Arduino will starts sending pulse width modulation(PWM) signals to the mosfet(Q1) in order to charge the battery .When the solar panel voltage was below the battery voltage ,this pwm signals will not send by Arduino . Then next the micro controller will check the battery voltage ,if the battery voltage was below 6.96 v volts then the battery will be charged in boost mode ,that mean the battery will be charged with maximum amperage ,this boost mode of charging will be done by sending pulse width modulation signals with 95% duty cycle .

Anker Astro Pro2 20000mAh Multi-Voltage External Battery. Need to charge more than just your mobile phone? DC 4.5-32V to 5-42V Booster Converter Industrial Power Supply Step-Up Regulator Module. This tiny portable wind turbine fits in your bag and charges your gadgets. In our current gadget-centric culture, one limiting factor for mobile devices is the capacity of the batteries that power them, and while we haven't seen any massive improvements in battery technology (yet) which would allow us to go for days between charges, mobile solar chargers and battery backup systems seem to be the only solutions (well, other than to actually stop using them so much).

Wind turbines are a viable clean energy solution, but most of the innovations in wind energy tend to be on the large scale, and since those devices aren't exactly portable, they don't lend themselves to mobile device charging. But one forthcoming invention may allow us to harness the power of the wind with a micro turbine, in order to charge our smartphones and tablets and other USB devices.
