The Chispito Wind Generator was designed to be simple and efficient with fast and easy construction. There are no limits to what you can do with wind power. There is nothing more rewarding and empowering than making a wind powered generator from scrap materials. Most of the tools and materials in this manual can be found in your local hardware shop or junk pile.

While I like the design, I feel that there were additional drawings/labels needed to make the blade construction easier to understand. I have no problem in figuring it out as I have a background in making aircraft propellers and blades, but without diagrams labeling each step, many will fail to grasp how it goes together IMHO
<p>First I wish to say that I think you have done things quite exquisitely. the drawings, descriptions &amp; directions are very well written &amp; put together. Because I am not very well educated on these types of things, some of it is a wee bit confusing for me, BUT, when I look at the drawings &amp; read the directions, it does not seem that hard to figure out.</p><p>Now about Vela Creations. I visited the website, and yes they have some very nice pictures on the site, However, I was rather disappointed by the lack of directions, measurements, etc. there were frames for different things that would be a lot easier to build if they had directions &amp; measurements describing what piece is what size &amp; so forth.</p><p>Lastly, for this ible I commend you Sir. I think if I can follow this, than just about anyone anywhere can also. Thank You for sharing Sir.</p>
<p>I am biding time (saving $) on solar panels for our Airstream, and was looking for a way to make a small wind generator to mount on top of the trailer to charge batteries while driving. Any reason why something like this wouldn't work? Is there a limit to how fast the blades/turbine can spin before it would create problems? I think I will likely find an old fan to use for the blades, as fan blades would likely be sturdier than the home made pvc blades mentioned here.</p>
<p>Well it would induce drag which means your truck will pull harder, let alone it being extremely inefficient. Use your truck alternator. Spend the money you would put in this into a bigger amp output alternator and larger wires to the trailer.</p>
<p>You'd have better efficiency charging the batteries off your vehicle's alternator. Drag will burn more fuel than the extra draw on your engine. Plus no rpm, charge controller or water concerns</p>
If using smaller blades, will drag really be that big of an effect (especially already towing a trailer?).
<p>Drag, whether on the alternator or wind turbine will be minimal in both cases, just more on the turbine. You're already driving the alternator, so charging the batteries would be an inconsequential addition. When parked, the turbine would be the way to go. And you're not likely to overspeed it.</p>
If I'm using smaller blades, would it really have that great of an effect (especially while already towing a trailer)? Plus, even while parked, if there's wind I'd be generating electricity.<br><br>And the trailer is of course already set up to charge from the alternator while towing.
<p>Hi - using this to charge while parked is an excellent idea. Using it while driving is an inefficient one. There are power losses every time power changes form so driving to generate wind to generate electricity will waste more power than charging from your vehicle's battery system. You are right, in your later comment, that a smaller set of blades will cause less drag but, as a direct consequence, they will also generate less electricity. </p>
<p>kidjedi, If you are thinking of having this running whilst driving, I would suggest that a Savonious Rotor (mounted on the roof of the van) would be better and far easier to instal. As it is low profile it won't be on a mast and there is less bracing required, to support against the wind flow.</p>
Yeah... I was actually already looking at switching the rotor design to Savonious. Thanks!
<p>the thing with this is.. there is no rpm limiter.. so if a high wind comes well those blades break off and can kill someone.. thats why commercial units use a mechanical or electronic rpm hall sensor or some kind of rpm limiter... so i woulndt use pvc blades you can buy blades that are designed for this pvc likes to shater into razors</p>
How much does this power? Like will this power a whole house or?And how long?
<p>i'm Impressed with how detailed how detailed your Instructables is...commendable job. </p>
<p>the power output of a windmill like this is compatible with how many solar panels?</p>
I have a permanent magnet 2.50 HP heavy duty treadmilll motor. It has a positive wire, a negative wire, and 2 blue wires that come off the positive post. What do I do with the blue wires? Do I have to use the bridge rectifier if I am using a charge controller? Any help would be appreciated.
<p>no brige rectifier is needed the i think the blue wires go to a temperature sensor which tells the treadmill what temperature the motor was. anyway for a wind turbine only use the black and red wires the blue wires are not needed</p>
Same. Anyone????????
fantastic! <br>made this for my yacht, I used a kids scooter for the swivel mount and the base.<br>thanks...
<p>As a hobbiest that has built a few of these I'll try to answer some common questions;<br><br>Keeping the wires from twisting. Place a plug/socket inline with the power cord at the base of tower, check it weekly for twisting, and if cord is twisting unplug it and un-twist it. I prefer twist lock plugs for this, ask at the big box store or go to an electrical supply house.<br><br>The 2 Blue wires on treadmill motors. Those are used for speed control of the motor <br>when used as a treadmill motor, they are un-needed for this application, just cut them off.<br><br>Motor Selection. Induction motors are not a good choice for wind turbines, the only way the can be used is by removing the rotor and adding magnets to it. Car alternators require being spun at high speeds, not a good choice. What you want is Permanent Magnet Treadmill motors.</p>
<p>i like it soo much</p>
<p>How does it continue to face the wind without twisting the wires?</p>
<p>can you use a car generator to feed batteries and then use a converter for the ac/dc conversion?</p>
If this is a dc brushed motor then the coil is the one rotating inside the magnets so it will automatically produce dc, adding a full bridge rectifier will ensure that if the motor spins in reverse it will produce the same polarity but it will decrease the output by 0.5 to1V
can ac motor be used? i got one out of my old fridge. it has three wires white blue and orange.so can i use diode bridge and acheive the same result as with a dc motor? on the side it says : merkle-korff industries model 3424rp-420 115v. 60 hz. idle: 1.20 amps rated: 1.4a-17mfd on/off: 2/20 sec p/n-10114804 any help would be greatly appreciated. thanks
turn the motor by hand and see if you can read a voltage above 1 volt. If not, it probably won't work without gears or pulleys, if at all. If you want a motor that works, go to <a rel="nofollow" href="http://www.velacreations.com/chispito.html">http://www.velacreations.com/chispito.html</a> and buy one from the recommended supplier.<br/>
acttualy it does have gears and it spins very fast, but when i connect it to my multimeter i get 0 volts. even when i use diode bridge still 0 volts, i tried every combination of the three wires, but no luck. does anyone know why? also i took it apart and noticed that it doesn't have any magnets(at least i could see any) in it, is this the reason?
The fridge motor is going to be an induction motor, so it wont work. Neither will a universal motor, as neither type has permanent magnets,
Since it doesn't have magnets, It is probably an induction motor, I don't think you can use them to generate electricity, Just my 0.02
yes, that is the reason. It would need to get up to speed before any output. You can take a look at the discussion board at otherpower.com for information on how to make a motor like this work.
How would you measure that one volt? I dont have any electricity measuring tools. Is there another way to possibly do it. If not how much would one of those cost?
i got my multymeter for less than 3 dollars, menards sells them for about 5 dollars.
Good project but the instructions in this page could be a lot clearer, or illustrated with some photos
I just loved it! I've searching for something easy and not expensive, now it is here. <br><br>Thanks.<br>Rodney,
In some circles, this 4 diode arrangement trapped in a little cube that takes AC and makes it DC is called a Full Bridge Rectifier. You will have better luck finding one at many electronics stores by that name. Frys Electronics sells them for about 10 bucks in California. Website frys.com

I built one of these and it works great. I bought most of the parts on ebay. <br /> <br /> The criticism I have with the design is the blades. I&nbsp; live in New York and we can get som serious wind in excess of 35 mph. The first day the wind gust went over 35 mph, the PVC blades snapped and crumbled into pieces. What a disaster!<br /> <br /> I wound up replacing the blades with some aluminum blades I found online at windynation:<br /> <br /> <a href="http://www.windynation.com/shop/index.php?act=viewProd&amp;productId=14" rel="nofollow">http://www.windynation.com/shop/index.php?act=viewProd&amp;productId=14</a><br /> <br /> So far so good and it has been 9 months. We have had a couple of days with 55 mph wind gusts.<br /> <br /> I would also recommend getting a slip ring if you live in an area with swirling wind like me. It will eliminate the tangling of your wires which run down your tower. Thanks for the article. I thought it was great.
