Pleech Video Capture

The Pringles Wind Turbine (a.k.a. Power Leech or Pleech) is an attempt to turn simple items found at the hardware store and elsewhere into a working low-voltage power supply. It is also the process for creating the turbine, designed so that other people may reproduce the product themselves.

Final paper pdf is attached below. The accompanying website for the instructable is here.

The Pleech Instructable appeared on the MAKE: Blog today.

This is great for the project. One of the points I drove home during my presentation was that I wanted the Pleech to be as much about the process of building one and sharing improvements with people as it is the end product. Hopefully wider public exposure will help bring more people into this process and start a good debate on the best way to build things like this.

I had a great time at the Mobilized conference this past weekend. I taught a brief workshop on Sydewynder to the folks there, and I got a pretty good response. Here's a Flickr photo from the event:

Thanks again to Paul Notzold for sharing his computer and running

Pringles Wind Turbine (Pleech) - Version One

Well, actually, it's only just now getting started, really. The instructable is part of a hopefully ongoing process for refining the Pleech concept by harnessing the power of the instructables community. It's only been up for a few hours and already has a fan! Woowee!

Just some more data for you from yesterday's events. Here's me at the end of the table studiously assembling my MintyBoost:

And here's me with a completed ShakeLight:

Me With Human Power DIY Flashlight: This is the human-power flashlight I built with a partner, who had never soldered before and did a great job, at the Bent Festival at Eyebeam.

I went to the Bent Festival at Eyebeam today--sorta. I didn't do the music--noise music makes me want to stick icepicks in both ears and both eyes. In fact, I think the Max/MSP teachers at Parsons next semester should hoist noise "musicians" out the window until they apologize for making our collective heads compress every time yet another one "discovers" how to modulate sawtooth waves with the fucking serial-in off a potentiometer circuit. It's a trick--get an ax.

I digress.

The classes I went to were fantastic and related very well to the user research I am doing for my Pleech project. The first was for a build of the MintyBoost, taught by its inventor, Limor Fried. Not only is it charging my wife's iPod as I write this (thanks for the guinea pig, hon!), it has the right kind of electronics (1.5V to 4.5V in, 5.0V out, 350mA max) that could power the kind of devices I'm interested in. This could be the supply end of the Pleech, minus the two AA batteries.

This week, I started building the prototype of my Pleech, the power leeching wind turbine.

The first thing I did was to assemble all the parts I could find. These included:

Pringles Can (cut lengthwise)

Two Used CDs

Chrome Paper Towel Holder

5/8 in. Dowel: (cut to length with two nails driven into each side and snipped to make a needle bearing)

8 Ceramic Magnets: (oriented in alternating North/South configuration)

400 Ft. 30 gauge magnet wire: (made into 8 loops of approx 275 2 in. windings)

Various Electronics: (including a bridge rectifier)

With these pieces together, I began the assembly process.

Heh. So, I just realized that I forgot to tag the last entry which would have put the previous Process post appear in the MS:I blog area. Dumb. No wonder Yury didn't see it.

I'm thinking about the Savonius Turbine in particular because of projects like
PicoTurbine.

At 300 windings per stator, the basic version of the PT should be able to produce between two and three volts, according to the authors. The plans have a pretty great discussion of the possible power coming out of the turbine.

For my Pleech project, I am trying to develop a low-cost, low-power, easily assembled generator that can be fixed to walls, fan outlets, and other infrastructure in order to generate environmentally friendly electricity for physical-computing graffiti and sentiti applications.

(Note: "sentiti" is my own coinage. It refers to any illicit sensor that can be placed in much that same way as graffiti. Think of it as an unauthorized reading as opposed to an unauthorized writing.)

So, I'm not sure how to lay this over my Venn or mind map, but I'll try to make this work textually.

My idea is called Pleech. It is a device that will generate power, via magnetic induction, from mechanical moving parts, similar to how some bicycle power generators work.

It is designed for activists, hacktivists, graffiti artists, and others interested in installing low power electrical work in areas without access to grid power or easy change of batteries. The Pleech will be left in place for as long as it is allowed to exist, and the public is welcome to plug in their own work into it once it is encountered.
