pedal powered tractor

I'm no designer but here's an idea I've been stewing on for some time. I've hunted but not found any designs for a pedal powered tractor. The very early tractors were very large;could to lots of work; but they only had 2 or 3 horsepower. They ran so slow you could count the piston strokes. The designs were simple and they were work horses. Our new high horse powered gas tools often cann't do nearly as much. The old machines used heavy flywheels; slow to start but they kept on rolling. With the improvements we've made in bike gearing systems why not make a pedal powered tractor that could do serious work with that same heavy flywheel technology?

Pedal Power LED lit night soccer!

My school entered into a "pedal power video" competition, the challenge was to make a video showing how to use alternative sources of energy, so my school had a soccer game at night where we lit the field up using pedal power and generators. This was done by attaching a belt to the back wheel of a bike and hooking it up to a treadmill motor working in reverse for power. Enjoy!

Pedal-powered airship gets half way...

A French amateur pilot's attempt to be the first to cross the channel on a pedal-propelled airship has failed.Stephane Rousson, 39, from Nice, took off from Hythe on the Kent coast at about 0800 BST and was half-way to the French coast by 1300 BST.But he was hampered by a change in the wind direction and called off the trip 11 miles from Wissant in France.Mr Rousson said: "I'm not disappointed. I feel happy because it had nothing to do with any technical failure."During the challenge, Mr Rousson was suspended underneath the balloon envelope in a carbon fibre gondola, powering the two propellers with his feet using a bicycle-like contraption. The most amusing thing about the whole trip is the safety system:Just in case Rousson found himself flying irretrievably high, he hung an open penknife from the gondola framework, with the intention of popping the balloon and heading for a splashdown.Sorry, that's the second most amusing thing.

Bike Lighting - Pedal-Powered 60W Incandescent Bulb?

I know, I switch projects a lot. I just can't stay focused on one thing for too long.Anyway, here's my idea:There's a local museum called Fort Discovery, which, by the way, is quite cool. But, there is this exercise bike they have there, and connected some how (I haven't been there in a while) is a few different home tools, like an incandescent light bulb, a drill, a hair dryer, and something else. There are switches, so you can turn whichever ones you want on, to see what you can power. The "exhibit", if you will, is to show how work = power. Now, I'd like to try to hook something like this up, except a few things will be changed:It would be a regular, moving bike.There would only be a light bulb.I want the power to be stored in a capacitor, because what would be the purpose of having a light while riding in the daytime?Now, besides from the point of me not knowing at all how to hook this up, I wonder if there would be a capacitor that would store enough power to light the bulb for a reasonable amount of time, if say, I used a 60 watt bulb. Then of course, I have a few questions, some of which I may of already said:How big would the capacitor have to be hold enough power to light the bulb up?How many hours (or minutes, if applicable) of moderate riding would it take to store enough power to light the bulb enough to see for about 15 minutes?Would the power stay in the capacitor so that I could charge the bulb a bit over the course of a few days?How would I hook such a circuit up?Could I hook the circuit up so that the power is stored from the wheel going around, rather than my pedaling?Thanks for any and all help, and if this turns out all right, then I may just put an Instructable up. I guess I'll have to see. Thanks again!

Wiring question?

Hi everyone. Long time visitor of Instructables, made a few items I've seen and my most recent project was adding a star power pedal to my guitar hero controller. I bought a audio extension cable with a male and female jack, 1/8th size. I cut the cable about six inches from the female end. I stripped about an inch, inside was a bundle of copper wire wrapped around a clear insulted wire. I twisted the exposed copper wire and tinned it, I stripped the clear housing and twisted it, tinning them as well. I tinned the exposed wire to the GND, and the clear to Select. Positioned the jack and everything went well. I took the male cable, connected it to momentary switch and connected the male cable to the female jack. Turned on the system and controller. Got star power and hit the switch with no response. I'm very confident in my soldering and know I did it correctly, so I was wondering: 1) Are these kind of cables capable of doing what I intend? 2) Maybe the GND or the Select button are shorted out on the board of the controller? Thanks for any help everyone!

I'm in the US, so the machine has been running on AC. Will a European foot pedal work on it? The machine (from the back) plugs into an outlet in the wall. A separate cord (on the side) goes from the machine to the foot pedal. Modern machines usually use the same machine connection for both the power and the foot control. If I try it on the AC machine, will I damage the machine? Aside from the motor, this is a strictly mechanical machine.

Wind Powered Quad-Cart

I haven't seen anything this on here so I thought I'd step up. Engineers (or anyone who fancies themselves A DIYer) I found a few days back I little some very interesting Wind Powered Rides...six-or-seven-ways-wind-powers-vehicles OK so we know it CAN be done, but can it be done by a DIYer? OK here's my concept, Design and shape are optional but basic components are such: Take a pair of multi-speed Bicycles, their gearing will be the basic propulsion for this vehicle. Take one of the "bikes" and hook up a prop where the pedals "where" and set the wheel output to be higher then the prop speed, this should take care of the foreward movement once going. Now for the initial starting power (Bike 2), this can either be by petal, or by electric (solar/battery- up to you) But the basis for this whole thing is simple energy transfer, if the moving air over the prop causes the drive wheels to go, and by having them geared higher, the vehicle SHOULD move faster the faster you go ..Right? Can I get some math to back this up? it sounds like it would work.

Help Making Tattoo Lab Power Supply Jumper / Converter + pic

This is what I'm talking about. can you see it?  it's the first thing that comes up on google image search when you type in "lab supply jumper." It's so you can plug in a tattoo machine and foot pedal into a lab power supply.  theoretically I get how it's working.  The foot pedal is what interrupts the circut.  when you press the pedal down, it makes contact and completes the circuit.  So, the machine needs to be routed through the pedal before getting power from the power supply (versus plugging the machine directly into the PS itself.  Cause then you'd have to turn the PS on and off to get the machine to work or turn off). So, I'm assuming that's why there is a cord going from the "machine" 1/4 terminal to the "foot pedal" 1/4 term, right?  Then the pos and neg banana plugs go into the power supply. specifically, my question is this:  do I have to solder to make this?  or can I just twist wires together?  and can I buy everything I need from radio shack, right?  I'm pretty confident I can do it either way, just need a diagram or something on how to wire everything. I'm also asking my brother who was an electrician before getting injured on the job- he's on disability now but may be able to help, too. =) It's gotta be easy to make, right?!?!  so help me do eeettt!!!  =0) thanks for any and all help!  Sarah ps- I attached a pic of the power supply I have so you can see it as well. and for the record, my tattoo machine is RCA not clipcoard, but goes to a 1/4 male mono all the same.  As well as my pedal. k, thanks. ;0)

Need some advice on fixing power issues with my instructable

So I built an Atari punk synth using instructions on this site and made it a bit more advanced. It has six 555 timers and button controls. Now I would like to power this thing with a 9volt wall plug, the same thing I use for my effect pedals, but I have crazy power issues when I set it up this way. It works fine when I just use a 9 volt battery, but when it's set up to be used with a 9 volt wall plug it seems like its getting way to much power. The sound goes crazy and it blows out my LEDs even though I have resistors on them. I've tried putting a resistor on the power jack, but it doesn't sound right when I do that and it still doesn't work right. So I'm curious what's exactly going on here. Regular effect pedals that run on 9 volts work fine with the wall plug and even the instructables on here say you can use them. But for some reason this thing only will work with a battery. Could it be the parts I'm using? I have a feeling it has to do with wattage and my parts just can't handle it.  Any advice would be greatly appreciated.

Very Small Scale Power Generation in Developing World

Hello Everyone, I volunteer for a non-profit which distributes solar lanterns primarily to students as well as people who are in need of the lights.  Things have been going well but a lot of people have inquired about us providing access to a higher powered version for various reasons and we've noticed that some households go back to their old ways when the lanterns don't receive enough sun during the day.  Temporarily we are solving the problem by having local entrepreneurs charge batteries for the families for a small fee but we feel that this should not be a permanent solution. It's not the price that's the issue it's that sometimes the people have to walk for a number of kilometers to get to the nearest charging station or have to cross dangerous terrain (I have personally experienced this). Over the last 3 years we have helped over 5000 families by giving them solar lights so we would like to modify all those units to have more stable energy generation. Our current version has an output of 5 watts. We are looking to buy or build a unit which produces a maximum 8wh an hour until the fuel source runs out or something that can generate in a more slower rate such as 40wh in 16 hours so we can let it run overnight and have the power stored in a battery. We are primarily a donation driven group so something with low cost and maintenance would be really great.  We highly subsidize the price to a large percentage of the households but we also provide them free for the lowest 10% of households who can't even afford the lowered price. I personally think that something which can generate electricity from hydrocarbons due to their high energy density and easy access would be ideal but I'm not an engineer so what do I know.  I'm not sure if this helps in any way but a number of years ago we transitioned a large number of houses from wood fired stoves to gas and as all the families that we help actually have access to gas I was wondering if any good technology exists where electricity can be generated by gas that can meet the low cost and maintenance criteria.  I've looked into thermoelectric generators but they are really inefficient and people will be wasting money to heat their house in a country where average temperatures are in the 30'sC I also see a future issue regarding battery degradation as we use small lead acid batteries and while thinking of a way to solve this I came up with the following idea and is one of the reasons that I'm posting on instructables. What if a pedal powered flywheel generator was built with a 200W generating capacity and 40Wh worth of 'storage'.  When you pedal you will spin up the flywheel and it will store the energy until you need the electricity again and we could also wire up the solar panel that we already use to spin up the flywheel.  So when the sun is out the panel is used and on rainy days and during the night you pedal for a couple of minutes for one hour of lights.  If the flywheel can store the energy for a number of hours then someone could pedal for a couple of minutes at a time throughout the day and not have to do it at night. This is just an idea that I came up with and if anyone has any ideas I'll be really interested in knowing about it (obviously the above solution is not ideal because they have to put some work into generation but it's the best that I can do).  I've quite recently been looking into different types of fuel cells powered by m/ethanol and others like solid oxide cells and they seem interesting (does anyone here have any experience in building these type of cells?).  This community has a lot of intelligent members who think outside the box so I'm confident that we can come up with something. This ended up being a bit longer than expected and if you've read this far, thank you. I wasn't sure about what section to post this in, square peg is the one I chose out of 5 so if this is wrong please feel free to move it to the correct section. Help and advice will be very much appreciated. Kindest Regards

Need advise on making a wireless to control a simple on/ off switch

OK , I am a tattoo artist. I want to make a wireless foot pedal to control my tattoo gun. This is how it works now. It has a foot pedal with a 1/4" phono mono jack that plugs into the power unit. When my foot is pressed down it simply closes the connection and tells the power unit to apply voltage to my gun which has a separate cord coming from the power unit. I would like to make a wireless for this. Maybe a simple remote control toy can give me all the conponets needed. I want it to be small , maybe a 9 volt battery supply. I can have my foot pedal  wire just 10" long going to the a sending unit with an antenna. Then alls it has to do is maybe close a relay that I can wire to a phono jack to just close the swicth to tell the power unit to turn on my tattoo gun. I know this is going to be very simple but for some reason im having trouble thinking of how to do this cheap. Thanks for the input. Jeff    P.S. the the jack input to the power unit is lioke a mono guitar chord. But all the power unit needs to see is a completed circuit. Thats it. So I just need to close a small relay wirelessly.

Wireless switch , need help on how to make

OK , I am a tattoo artist. I want to make a wireless foot pedal to control my tattoo gun. This is how it works now. It has a foot pedal with a 1/4" phono mono jack that plugs into the power unit. When my foot is pressed down it simply closes the connection and tells the power unit to apply voltage to my gun which has a separate cord coming from the power unit. I would like to make a wireless for this. Maybe a simple remote control toy can give me all the conponets needed. I want it to be small , maybe a 9 volt battery supply.

How can I power a digital projector from my exercise bike so when you pedal the video plays?

It's for an installation I've made for an exhibition this sunday so I'm stuck for time! I want people to trigger the video (linked above) by cycling the bike.. I suppose I'd like to do this mechanically rather than electronically- rather than be turning the projector on and off all the time I'd like it to be always turned on and when the pedals start turning a piece of cardboard covering the projector lense is lifted, revealing the video. Would really appreciate any advice! xAoife
