How can I make a sustainer for an acoustic guitar (working on the principle of an e-Bow)?

I mentioned acoustic sustainer because I have been told it is easier to build than an electric sustainer. I have been told that piezos can be substituted for a normal mag p/up, then use a monophonic coil driver and the amp/preamp and AGC (Automatic Gain Control) to even string response. But I have had difficulties with the PG Sustainer thread instructions, particularly for acoustic guitar. There are various amplifier and preamplifier circuits available, but I am a complete novice to electronics. I have a more knowledgeable friend who is able to work from circuit diagrams, but I need to be very clear about what I want him to do, and need also to be able to access the components. Thanks in advance for your help.

Sustainable housing development

Is there anyone that has gone through the process of setting up a sustainable housing development, preferably in Australia, but would be happy to learn of some expriences elsewhere. I've built my own house but am now considering to setup a project to build more efficiently - perhaps get 15 to 20 people together and buy a larger piece of land which would be lot more efficient to build on - with share facilities etc.

Schematics/Instructions for guitar pickup Sustainer?

I saw some pickups  for sale, sustainers, I thought "oh thats cool" but they are way above my budget. Besides that I love the sound of my current pickups. What I want to know is how to make a sustainer  with on/ off switch for my 3 coil single coil strat. It would be neat to have on/off but I could do without and just make one pickup sustaining. Any tips schematics links, etc, are very welcome.

Cheap, sustainable or recycled stuffing

Hi all, I'm part of a project where we're making soft sculptures to cover a tree trunk. It's for a sustainable festival, so we have to be mindful of re-using and recycling in our artwork. The problem we're having is with stuffing. It's only a temporary artwork for 5 hours so I'm not too concerned with waterproofing, but trying to make the sculptures look good when stuffed with shredded newspaper, plastic bags or chopped up old clothes is difficult. I'd really appreciate any ideas you can suggest! Thanks.

Submit your instructables for a sustainability guide!

Hello community! I haven't posted any instructables in a long time because I've been in college, studying for a sustainable manufacturing degree. After being frustrated at my lack of tools and workspace, I realized that I could just use other people's work! Bear with me here. I'm not stealing your projects or ideas, far from it. I am looking for a few instructables that I can analyze and review based upon their sustainability. I will compare and contrast several projects, relate all this to sustainable manufacturing principles, suggest changes to design or process, and then finally write it all up and publish it as an Instructable for the community to enjoy and learn from.  All projects and photos will be fully credited to their original creator.  I don't have an exact time frame of how long this will take, but I estimate that with in depth research and ample procrastination I can get the guide done in two months at the absolute maximum.  I'm also not sure how many projects I will need for the guide, but I'd like to set it at no more than 5.  So, if you are interested in having your project analyzed and expanded upon for the benefit of the community, comment here. Here's a few guidelines for what I'm looking for.  PICTURES. If I don't know what the hell your project looks like I can't do anything with it. Also, you must be okay with me copy pasting them into the guide and editing/marking them.  WRITTEN DETAILS: Again, if I don't know what you did to produce the project, I can't really give any complete feedback on it. The more in depth and well written the better! I might very well quote you directly in the text. DURABLE GOODS: Because I'm a manufacturer, I deal with things that are built, in one way or another. I'm sure your recipe is delicious or your computer code can power a spaceship, but I can't really practically analyze it if it's been gobbled up or is buried in some program files. I don't speak code. AT LEAST 6 MONTHS OLD: one of the parts of sustainable practice is to make something that lasts. Therefore I would like to use projects that were made a while ago so that I can ask you how the object is holding up and if it needs to be repaired, how it has been used, any changes you would make, etc. IT DOESN'T HAVE TO BE GREEN AND HEALTHY: It wouldn't be much of a compare and contrast guide format if everything produced clean energy and rainbows. I need a spread from environmentally friendly projects to things that belch black smoke and get gallons to the mile.  YOU CAN TAKE CONSTRUCTIVE CRITICISM: I'm analyzing this from a professional standpoint, not a personal one. If your object has killed a couple of owls in the forest, that obviously isn't very sustainable, and I will mention it as a negative thing. If you can't take this kind of critique, then you won't like this guide very much.  YOU ARE WILLING TO COMMUNICATE: I'll be asking you some questions about your project, if you never answer your Instructables messages or reply in one word answers or 133t5p34k I can't get any useful info for you.  if I use your project you get a patch from me, and further exposure for your project on the site, as well as a lot of good information for a re-design or refinement of your original idea

2007 High Country tour of sustainable Living

Hi all. So here I am on fall break. Two days of not going to classes. I decided to tell ya'll (I'm in the south, I'm allowed to say that) about this weekend.This weekend was a big weekend up here in the mountains, and ASU's Homecoming eclipsed some great stuff, let me tell ya'. Instead of going to the game I decided to go on the 2007 High Country Tour of Sustainable Living. It was amazing! let me fill you in on some of what happened.Friday evening I found out about this and decided I couldn't miss it. So I got up bright and early Saturday morning, put on my robot t-shirt, and headed out. People started arriving around 8 AM and kept coming until 8:45 when we were finishing up breakfast . We all piled onto a biodiesel fueled bus and started for our first destination. I had had my coffee so I was up for talking at 8:45 on a Saturday morning. Right away I met some neat people, and we talked about bio-fuel in general, Who Killed The Electric Car, and the Appropriate technologies department at the university. We pulled up to a farm to be greeted by Ned Trivette and a 65' tall wind turbine, back dropped by the beautiful mountain scenery. Grid-tied and nearly maintenance free, this turbine provides about about 10% of Ned's household power usage.After talking about wind power and how Ned's setup works we loaded up again and headed to the Kennedy residence out in Vilas. We made it as far as the road that turns off to go to their house. There was no way that bus was going to make it up the hill to the house, so we all got out and the few cars that were there started shuttling people up while others of us walked. I walked, and let me tell you, that hill is STEEP. We got to the house without any mishaps and learned about this high efficiency house. It was facing south so it can soak up the sun in the winter months and had deep overhangs to shade the house in the summer months. By far the coolest (pun intended) part of this house was the thermal radiant heating system. Panels on the roof heated the 750 gallon Carolina water stove, and from there the water was pumped throughout the house to the radiant heating system in all the floors. Highly efficient and fascinating. After this we headed off once again. Here's where our schedule got interesting, and everyone was helpfully flexible. We apparently decided to take a "short cut." Someone thought we could make it on this steep dirt road that we took. We did make it, but not before getting stuck a few times and running over a rock. pieces of the bus were falling off and smoke from the tires was going everywhere! Once we finally made it over the hill we didn't have much more trouble. Instead of going to lunch, like we were supposed to do, we went to the ASU Biodiesel research facility. This was the highlight of the tour for me. I learned so much related to my latest endeavor, biodiesel. (for some reason spell check doesn't like that word.) We met Jeremy Ferrell, the guy in charge of all of it. He showed us the process they use to make it, and discussed all the latest research. This facility is amazing! It's completely sustainable. They have solar panels so they're making as much power as they're using, and in their passive solar greenhouse they have a "living machine" to recycle their gray water. There were things (algae and the like) growing everywhere, and the same solar thermal system that we had seen earlier, to heat water. I'm actually going back there sometime in the next few weeks to pick Jeremy's brain about biodiesel "stuff." ASU Collaborative BioDiesel projectAfter this was over and I was dragged back onto the bus we finally went to get some lunch. We were starving.We went to the Hill/Mitchell Residence for lunch. This house was awesome. It was only about 1600 square feet and had a concrete slab between the two floors, to retain heat. They had the radiant heating as well. I didn't get any pictures of the inside of the house but it was at least as cool as the outside. They also had a great garden going. Over lunch we had a speaker who talked about green building, and a lot of what goes into it. (I don't remember his name, sorry!)Our last destination was the Marland residence. It stands up on a hill above the university, in direct sunlight. This house is incredibly energy efficient and quite pleasing to the eye. (it was purple). With very few electric lights in the house that need to be on in the daytime, most of the windows face the sun, with overhangs on the roof for shade in the summer. It also had a tank-less hot water heater, which I had never seen before. It's apparently very energy efficient. So that was this years tour! (or the good parts, at least.) apparently it happens every year, so I plan on going in the future. Let me know if you guys have any questions or comments, in case I got any of the info wrong or left some out. (a lot of this is from memory and the handout we got)Thanks for reading,-DMC

What would happen if we combined current pellet stove technology with a Stirling engine through an outside wall?

In Theory, A Stirling engine works on a difference of temperature. For many rural homes there is great expense in developing and sustaining power lines. These homes are already heating from an inside source, and create a difference of temperature, depending on the proximity to the firebox of at least 2X. If developed as a mobile stove, you could glean a mobile power source only dependant on supplying a small chamber with fuel. Such an engine would be able to sustain on green fuels as well if heating an area wasn't a factor. It might even pay for itself in an AC situation where the thermal difference is reversed. Why haven't we put a power source in every appartment using electric fuel?

Green Design Thrives on Cooperation and Hugs

While there are LEED standards for architecture that are often brought into consideration, there isn't much in terms of product design. Many companies want the design for their widget to be done and quickly move on to production. In an effort to fight the good fight and get sustainable ideas in from the beginning, an agreement called the Designer's Accord has been established among designers.Signers to the Designer's Accord agree to initiate dialogues about sustainability and carbon footprints with the companies who hire them. They also agree to educate their own staff about the importance of materials and design in production.One of the big kickers here is that the signers also agree to share what they've learned about sustainable design with each other. While avoiding disclosing any secrets about the companies they work for, they plan on building a global knowledge base so that we can all be a bit greener a bit faster. It's a noble concept and thousands from prominent firms and small companies have signed up. Time will tell if all of this will truly help out, but for now the project looks to be in the big group hug phase with many promises of glorious things to come.Hopefully, they will.

NPR: $100/Barrel of Crude

This came up in another forum, but I heard the report too.... So today, there was a broadcast on NPR (yes, I admit that I listen to NPR :p) about a $100 per barrel crisis.... If you didn't know, a barrel of crude goes for about $93. Personally, I don't think it will cause a crisis - it's not as if it's going from $30 to $100 in a week. However, seriously, are the masses comatose? It's not like no one has been warning them of this - and the consequences nowhere near sustainable living. Arrrrr.... I've been saying it for awhile - if we don't regulate ourselves, nature is going to take the kind liberty of doing that for us (and that won't be pretty). Soylent Green anyone? I mean, I recently read that the average American will consume about 500,000 gallons of water per year... whereas some of the Nordic countries, consumption is around 17,500 gallons per person... By the way, the US has a very limited water store supply :/ US has 5% of world population... 25% of world total CO2 emissions. China, for example, has 22% of the world population - but only 15% of the world's CO2 emissions.... US has 5% of the world population - and 29% world CO2 emissions from fossil fuels.

From this week's Science magazine online abstracts:Self-Sustained Replication of an RNA EnzymeTracey A. Lincoln and Gerald F. JoyceAn RNA enzyme that catalyzes the RNA-templated joining of RNA was converted to a format whereby two enzymes catalyze each other’s synthesis from a total of four oligonucleotide substrates. These cross-replicating RNA enzymes undergo self-sustained exponential amplification in the absence of proteins or other biological materials. Amplification occurs with a doubling time of about one hour, and can be continued indefinitely. Populations of various cross-replicating enzymes were constructed and allowed to compete for a common pool of substrates, during which recombinant replicators arose and grew to dominate the population. These replicating RNA enzymes can serve as an experimental model of a genetic system. Many such model systems could be constructed, allowing different selective outcomes to be related to the underlying properties of the genetic system.

External postings and attribution

Did somebody from the Instructables staff post a version of my instructable on Sustain Lane without attribution or credit to the author? It certainly looks like it here where it says "Instructables - Premier Partner" while the content is clearly my instructable with no author attribution or credit to be found. http://www.sustainlane.com/reviews/how-to-create-a-simple-aluminum-air-battery-from-a-soda-can/MD2QLHMIKYY78J73MY3DLABDNAQI
