Generator from scooter motor

This project came about because someone cut the power line going to my house. The power company was slow to fix it, so I cobbled together a way to charge auto batteries for my invertor. The generator is the motor from a discarded electric scooter ( model MY1016 from JX Motor Co., rated 24v input and 2750 rpm). I removed the motor, it’s drive chain, and sprocket wheel and attached it to the frame of a discarded bike. The pictures show the details. By cranking furiously, I can charge a 12v battery with about 3/4 amp of current. There is a small epoxy rectifier to block the battery from driving the motor. This thing was made from parts on hand and cost me only the assembly time. I don’t have any sources or price lists.

bicycle generator

Has anyone ever tried to build a generator that would fit inside the bottom bracket of a bicycle using the spindle thats attached to the cranks and pedals? seems it would work better than the ones that rub on the tires.

Bicycle Generator upgrade for a rig

Okay- My boyfriend thinks I'm absolutely crazy, but I would like to modify the bicycle generator a la this instructable. I was hoping to have some way to attach it to an axle of an 18 wheeler tractor. Then the trouble would be hooking up the battery to a generator so we wouldn't have to pay for gas to power the ac and tv when we're sitting still. I'm hoping some good mind out there would have some tips! Many thanks!

DIY generator

I'm new to this forum. I just got my welders certificate. I've seen on the web some projects that convert an auto alternator to a 300 amp welder. I live in an apt. and don't have 220V. I have a new mig welder and it works super for thin and medieum guage metal. My buzz box needs alot of power, about 15 KW, and even used generators are out of my range. Can anyone help?

Pulse Generator, part suggestions?

Hey, I want to make an external pulse generator, mainly so I can power a simple coilgun. I know I have to have a bunch of capacitors hooked up in parallel, but what value would be ideal? And what kind of transformer do I need? Say I use a 9v battery, how would I calculate the ouptut voltage? I know trial and error would work best for me, but I don't have any transformers lying around so I need advice on which one to get. Thanks.

BIKE GENERATOR?!

Hey, I'm much more of a mechanical guy than an electrical one, and yeah, I'm trying to be won over, but I think this project might help me bridge the gap if I can get it rolling. what do you guys think about buying maybe six or so friction light generators and disconnecting the lights, putting two on the front wheel, four on the rear, (they rub on the side of the tire) and wiring them all together to produce a power source? like I said, I'm horrible with electrical stuff- maybe you could even build a larger generator like I saw in another instructable, but do you think it'd be possible to either create a car-adaptor-style outlet, or even a functioning regular power outlet with that idea? what about an electric bike that charges itself while pedal in that sense? talk to me people!

Faraday generator for your bicycle led light

I'm looking for a way to make a Faraday generator of some sort to put on my bikes rear wheel to power my led lights( a 56LED 3-1.5v AA's and 26LED 3-1.5v AAA's. I found something close that may work with some design changes. I found a magnet site with a magnet that could work with the wheel. I would mount it to the rim itself and put the copper coil attached to the bike. The problem is winding the coil of copper wire, gauge and what type of direction to make it. And the possible use of ultra capacitors or a built in charging system for the batteries. I would need a minimum voltage of 9 volts for the lights to run. The way the example light works is with a fly wheel and the bike's rim would take that place. The design is pretty simple and should work fine. The hub is 1.5" diameter and .5" deep with room across for the bundle of wound wires. Just looking for input and if anyone has thought of this before. Thanks.

I need help connecting a small wheel to a DC motor, yesh.

Hey all, I'm making a little DC generator for my bike (just to power an LED for now), but I cannot seem to connect a wheel to the motor's shaft. It's not too large of a motor, and I had some toy wheels from some little car, but they don't fit and I can't figure out a good solution. Does anyone have a good way to do such a thing? Or maybe even to make an altogether new wheel?

Wind Power Charge Regulators

Hello!! I need some help here...I am very "green" when it comes to alternative energy, so bear with me please! I recently decided to put together a small wind generation system to power my workshop. System is comprised of a 38v Ametek PMDC motor, 6.8' tri-blade array for propulsion. I also intend on installing a 2000 to 3000 watt modfied sine wave inverter powered by my battery bank to provide AC voltage to the shop. I want to be able to used the majority of the power created by my wind generator. I understand the concept of using a "shunt" but do not have a need for hot water or useless lighting. My question is this, would the Flexcharge NC25A charge controller (www.flexcharge.com/flexcharge_usa/products/nc25a/nc25a.htm) be sufficient enough to used in this system? Or is there something else out there that would maintain my battery bank without shunting the load when the bank is fully charged....Thanks in advance.

Sleep deprived brain fart...Solar Panel Lightbox Generator

OK first off let me tell you I don't know much at all about solar panels, wiring, or electrical at all. So to those that want to flame save your breath. Now at 3:30 am my time I woke up and since I couldn't sleep logged on to Instructables because something was bothering me. The something that wouldn't allow me to get back to the sleep which I craved was the idea for a Solar Panel Lightbox Generator. Now I see the logic in thinking about some of the perpetual motion generators and how they are impossible. And I believe my idea is not possible either, but till I get some info from someone that knows more about electric and solar panels I don't think I will be able to rest. So here is the idea, someone please explain how my thinking is wrong. Build a box of solar panels faceing inward with a light source inside of the box. once the panels start to charge a battery, use the battery to power the light. First off I know direct sunlight is optimal for the panels, but I'm thinking "outside/Inside" the box. How much light does it take for a panel to actually start creating current? How much energy does the light use to create the light? How do you measure how much light (candle power?) a bulb/LED or what ever produces and is it enough to " power " a solar panel/cell? My thinking is if a LED/incandescent/haligion light can produce enough light, with the right amount of solar cells it could power its self after start up. I know things degrade, bulbs burn out and all that. What I guess I'm saying is mathematically could this happen? Since I know so very little about solar and electrical in general is it possible? And if it's possible could more panels be added to make more power than it uses? There's my brain fart, feel free to point out the flaws so I can get some sleep tonight.

USB generator

I know a USB port supplies 5V DC, and that my generator will obviously produce AC current, but I'm not sure the best way to convert AC to DC, then how to step my voltage up to 5 volts. My generator uses 6 wire coils in a circular pattern. 12 neodymium magnet rotate over the coils. This doesn't seem like the most efficient design ever, but that part is a stock university kit, the wiring is up to me. I've only been able to test each coil at a time, and each one produces .5-.7 VAC. Do any electricians out there have some tips? When all is said and done, I'll definitely be posting an instructable on this.

At first i thought i can implement it using a multi vibrator, but it it turning off and on too fast, since the output of the MV is a square wave. I want to design a simple circuit that can generate more slowly rising waveform (like sine or triangular) and can also drive a load of at least 100 mA and have a time period of 10 seconds or so.

Trimmer Engine Generator

   Hello Instructables community.    I was thinking of making a 12 volt battery charger with a trimmer engine (pictured) connected to a scraped car alternator (I found several on eBay). But I have a few questions: 1. Would such a combination work as shown in the illustration?  2. Would it be best if I directly connected the engine to the alternator with no drive belts or chains, or would the high gear of the large engine gear and small generator gear be worth the extra trouble.  3. What is the best way to connect the two? And 4. Where should I remove the engine from the "trimming part". Any answers will be appreciated.                                                                                                                       Sincerely                                                                                                                  Confused DIYer

Potenco's Latest Pull-Cord Power Generator - Wired Video

Check out Potenco's latest pull-cord generator in this interview Colin did for Wired. Video: Potenco's Latest Pull-Cord Power GeneratorA couple of weeks ago, we headed out to Potenco's amazing headquarters at the decommissioned Alameda Naval Base to check out their power generator for the developing world.It looks a bit like a yo-yo, and generates an average of 25 watts of power in normal operation. That's enough to power twenty minutes of cellphone talk time with just one minute of pulling.Their engineering feats could ultimately enable millions in the developing world to access information through their cellphones and internet devices, and light their homes with smoke-free lanterns. Now all they have to do is get them out into the field.One proprietary thing we couldn't show you was the Potenco cord testing room, where a Rube-Goldberg looking machine put dozens of types of strings through thousands of simulated yanks and pulls.Nicholson Baker envisioned such a machine in his book, The Mezzanine, but for shoelaces, not power generators. We echo his thoughts on the relationship between finding the right strings and civilization's advance: "He had constructed a machine and strapped hundreds of shoelaces of all kinds into it, wearing them down over and over, in a passionate effort to get some subtler idea of the forces at work... Progress was being made. Someone was looking into the problem."Enjoy the video! Thanks to Potenco (especially Mike Lin and Colin Bulthaup) for letting us come out and Michael Lennon and Annaliza Savage here at Wired for putting it together.

Too many volts from a bike generator

I took a treadmill motor and hooked it up to an excersize bike in order to charge a 12v battery and power an audio system.  Unfortunately, it worked far better than I ever hoped and is pumping out 75v at a max pedal, 45v on an easy ride.  I've looked into various charge controllers, but they only charge batteries close to the input voltage, and step-down voltage changers take it directly down to 12v, too low to charge a 12v battery.  Any suggestions?  Thanks.

Hydrogen gas by combining electron- generating bacteria & small electrical charge...

Hi,Pennsylvania State University researchers last week announced that they have developed a method of producing hydrogen gas by combining electron-generating bacteria, acetic acid and less than .2 volt source in a microbial fuel cell. Info at this URL... http://afp.google.com/article/ALeqM5iXbROJgdF3_6BtG3TZFEs9hiw8CgI first heard about this last week on NPR's Talk of the Nation. Here is NPR link - http://www.npr.org/templates/story/story.php?storyId=16343702&sc;=emafThe researcher who led the project Bruce Logan, the director of the Hydrogen Energy Center there said last week on the show that this was actually a relatively simple process.He claims 90 percent efficiency. Also claimed is that the process produces 288 per cent more energy in hydrogen than the electrical energy that is added to the process.I would love to build one small scale and combine it with solar panels. Or maybe try to generate some hydrogen and try using it as a fuel supplement for my car using something like this - http://www.hydrogen-fuel.ca/ . Anyone willing to tackle this one?

Hey guys, im doin a project, ill be using two cordless drill motors with a maximum output of 12v each and unknown amp atm. My question is this: Both the outputs of those two motors will equal 24 volts, but I want 12 volts and increased amperage - this will, for the most part, be used to charge a 12 volt lead acid battery and I dont require the safety police on this one. So, can I take both outputs of the dc motors and wire them in parallel and have a resultant potental 12v maximum? Or will I have to use electrickery??

Vandergraph generator

I am interested in building a small  vandergraph generator.  I am thinking this will certainly be no taller then 2ft and likely closer to 1ft.  I understand the general principal of how it works and this should be a good first voltage project that I should have everything I need for.  What has been holding me back for quite some time is that I could not come up with a decent belt for the inside.  But I read on the forums I think that leather is a good belt to use (or human skin).  This seems very odd to me and maybe I am missing something but is this really a good thing to use as a belt?  It would be nice because I could cut it as wide and long as I need and then sew it into a belt with some thread.  I happen to have some leather laying around from some crafting I have been working on.   Then as long as I am making this thread I was wondering what the best "tube" would be that the belt runs in.  I had considered making a plexi glass tube with hot glue to hold it together.  I think it could be cool to have a see through setup.  But I want this to work as well as I can get it.  So if a different material would work better I am open to suggestions. Also I will try my best to find my camera and post step by step photos once I know what the heck I am doing.

Windbelt, Cheap Generator Alternative, Set to Power Third World

Working in Haiti, Shawn Frayne, a 28-year-old inventor based in Mountain View, Calif., saw the need for small-scale wind power to juice LED lamps and radios in the homes of the poor. Conventional wind turbines don't scale down well -- there's too much friction in the gearbox and other components. "With rotary power, there's nothing out there that generates under 50 watts," Frayne says. So he took a new tack, studying the way vibrations caused by the wind led to the collapse in 1940 of Washington's Tacoma Narrows Bridge (aka Galloping Gertie).Frayne's device, which he calls a Windbelt, is a taut membrane fitted with a pair of magnets that oscillate between metal coils. Prototypes have generated 40 milliwatts in 10-mph slivers of wind, making his device 10 to 30 times as efficient as the best microturbines. Frayne envisions the Windbelt costing a few dollars and replacing kerosene lamps in Haitian homes. "Kerosene is smoky and it's a fire hazard," says Peter Haas, founder of the Appropriate Infrastructure Development Group, which helps people in developing countries to get environmentally sound access to clean water, sanitation and energy. "If Shawn's innovation breaks, locals can fix it. If a solar panel breaks, the family is out a panel."'Frayne hopes to help fund third-world distribution of his Windbelt with revenue from first-world applications -- such as replacing the batteries used to power temperature and humidity sensors in buildings. "œThere's not a huge amount of innovation being done for people making $2 to $4 per day," Haas says. "Shawn's work is definitely needed.'http://www.popularmechanics.com/technology/industry/4224763.html?series=37

Motor and circuit choice

Hi folks, I'm a first time poster on here but I have been browsing the site for years.  Finally taking the plunge and starting my own project.

Bio-mechanical electricity - 13W per knee.

A stroll around the park may soon be enough to charge the raft of batteries needed in today's power-hungry gadgets.US and Canadian scientists have built a novel device that effortlessly harvests energy from human movements.The adapted knee brace, outlined in the journal Science, can generate enough energy to power a mobile phone for 30 minutes from one minute of walking.A slow walk can generate an average of 5W of electricity, but they have models that will produce 13W - enough power for a one-minute stroll to provide half an hour of talk-time.The prototype makes you sound like an extra in Terminator, but the inventors are predicting saleable products within 18 months, probably powering (in the first instance) modern prosthetic limbs.Soldiers may also benefit from wearing the knee brace to power the multitude of devices they now carry ,such as night vision goggles and GPS."They treat batteries like they treat food and water - they are so essential to what they do," he said.Link to BBC articleLink to BBC VideoLink to Science Magazine articleThis whole idea seems like a "Good Thing" to me - even without the computer-control, I don't see why a pedestrian or jogger couldn't wear a pair of generators similar to those in wind-up torches, charging phone and PDA as you stroll around doing the shopping or jogging across the park. Get them with a Nike or Motorola logo, and we'd see hundreds of people wearing batman-style utility belts, stacked with all the gadgets the modern human "needs". It could really help wearable computing take off as well.

Universal motor projects

Hello, everybody. I took apart a universal motor recently. The motor itself is broken and does not work. However, I would like to know whether I could rewind the copper coils around the silicon steel motor core in order to make a toroidal transformer.  I have heard that motor cores are sometimes grain oriented, which would significantly reduce my transformer performance. This motor is, however, about a decade old. I want to use the existing motor coil as a primary, and then wind thick power transmission line wire as a secondary in order to get a high amperage output. Is this possible? I would also like to know whether there are more interesting projects out there which I could attempt. I have heard of people making generators from motors, for example. However, winding a transformer is my primary goal. I have attached pictures of the motor. Please tell me whether the above mentioned transformer is feasible. Sorry for the picture quality. Thanks in advance.

High voltage & marx generator

I'm looking at some instructables, and the simplicity of the cockroft-walton generator is quite interesting. Because I've always been fascinated by lightning and electric sparks (ever since I saw a wimshurst machine as a kid), I was thinking of building a CW generator, to power a small marx generator. Now, I found the parts, but I don't know much about electronics, so I have a few questions, and I was hoping someone here could help me out. 1) For ceramic capacitors, some are labeled for instance '15kV', while others are '15VDC'. I assume the latter only work for DC input, is this correct? 2) If I were to make a CW generator using a few 400V capacitors and a fuse (assuming I don't f*k up putting it together) like this: https://www.instructables.com/id/High-Voltage-Power-Supply-For-Marx-Generator/?&sort;=ACTIVE&l; imit=40&offset;=80 Is there a risk of blowing a fuse in the house, or is that fuse in the setup enough protection? 3) Is there any risk for other electrical devices, like a computer, when I plug this in? 4) I work at a computer repair shop, are there any useful components in power supplies, old screens...? Thanks in advance!
