Plans or a place to order a bike rack for a 4-wheeler

Hey Folks, I'm looking for plans or a how-to for building a bicycle rack that mounts to a standard rear rack on a 4-wheeler. I looked a ball-mount hitch type bicycle racks (4-wheeler doesn't have a receiver hitch) for vehicles and they aren't going work. Ideally I'd like it to hold 2 bikes, but at this point I'd take anything. I just can't seem to find anything. Thanks!

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!

2001 Yamaha Warrior Stalling out when warmed up and wont start back up until cool?

Hello fellow instructable users! I have a 2001 Yamaha Warrior (as seen in profile picture). When ever I go out to ride the four wheeler has a hard time starting. I have to use a lot of starter fluid and patients (about five minutes worth). Once I finally get going it seems after about five minutes, about the time it takes for the machine to really warm up, it stalls out and I can get one more start out of it and then it stalls shortly after. Another important point is the fact that the spark plug is unusually dry. After the bike cools down I can get it to start again and ride for about a whopping five minutes and then its dead until it cools down again. The situation is that something is getting hot and changing, causing the bike to stall. The bike has a brand new battery, ignition coil, and the starter is in very good condition. What should I check for next?

LAN Party Bag

I need to build a LAN Party Bag.  Or rather, a LAN Party Bag that needs to hold 3 monitors, along with a desktop.  I had a few metal-related ideas, but sadly, no welding equipment.  The computer weights 100+ lbs, so I can't use anything too cheap.  The monitors are 19" widescreens.  Plastic is too brittle, wood would have to be way too thick, and I don't have welding resources, materials, or equipment.  I don't expect to be wearing it, but rather rolling, then lifting into the car, and out when I arrive.  One idea is to maybe buy a hand truck, and mount sheet metal to the back (side facing wheeler), line with insulation, and put clips along the sides and bottom (the backpack-style clip-and-socket).  Any ideas are welcome.

How do I conctruct a powerful night vision flashlight?

I want to build a powerful night vision flashlight that is capable of producing a bright enough beam of light that it will travel at least 75 yards or so. I want to use this light for hunting wild hogs at night. The light needs to be visible to humans but not to animals. I want to try to build one instead of spending thousands on some of those fancy ones .It only needs to be transported to and from the stand so it does not have to be a light hand held flashlight. I am wondering if some kind of night vision Q Beam is possible. That would be perfect. It is fine if the unit is heavy due to batteries or whatever because it will be transported by a four wheeler. Any help that you may be able to give will be much appreciated. Thanks

Electric car 3 times more efficient than a Prius

OptaMotive is working on the E. Rex, an electric three-wheeler that goes 0-60 in under 5 seconds, is three times as efficient as a Prius, and has a range of 100 miles. The focus is on the driving experience, though, and there's barely enough room for the driver and passenger, much less a couple more friends or some groceries in the trunk. OptaMotive is predicting a top speed of 160 mph, but hasn't had a chance to test that out yet. Right now the car is in the testing phase so there's little chance of getting to drive it any time soon. If it does go on sale it's likely to cost over $50k, making the Prius a hell of a deal in comparison. Check out the link for much more info. E. Rex Is a 3-Wheeled Electric Hooligan

Need help with a wiring diagram for a on/off/on switch parallel/serial battery

Ok I'm not really electronic savvy but I can solder and follow a diagram. This is what I want to do: I have a toy four wheeler for my kids. Has one battery and a push button that makes it go. When you release the button it stops.  I want to add another battery and push button so when you push the original button the batteries run in parallel. The speed will run the same as with the one battery but twice the run time. (please correct me here if I'm wrong) When you push the the new added button at the same time as the original button it will switch to running the batteries in series so it will be faster running on twice the volts. So i'm figuring I need some sort of on/off/on 6 pin switch and a push button switch but not sure how to wire it exactly. Found this which gets me close but I want to add in the push button switch to make it work instead of the toggle switch.  https://www.instructables.com/id/SIMPLE-ParallelSeries-Select-Switch/ The original button is on the handle and you push it with your thumb. I will add the new switch on the other handle. Something like this https://www.ebay.com/itm/5x-Red-Square-Pre-Wired-Momentary-Push-Button-Switch-Reset-1-2-AC-250V-Car-12V/182680718419?epid=11005923516&hash;=item2a889e8c53:g:YoMAAOSwr9VZwoA7 Any thoughts on this would be awesome!

East Coast HPV Challenge - Quick Update

So yesterday started the east coast human powered vehicle challenge by ASME. Yesterday was the design portion of the event (and safety inspection/testing). So far we've seen lots of two and three wheelers -- everything from 100% upper body powered (for paraplegics) to a LWB tadpole leaning trike (wheels and all -- no banana lean there). Someone even showed up with a 75+ tooth front chain ring (it's a monster)! We had teams from all over, including two fro Venezuela. Some vehicles are fully faired, more partially. Many of man (and woman) hours invested in everything ;) First picture -- UCF (us!) - in the background is last year's model (complete with scars from several crashes). Note this year's design has rear view mirrors, ventilation and a vacu-formed windscreen :D Our ventilation is even adjustable (climate control perhaps? :P). Second and Third Picture: Leaning Trike -- also has conventional steering (no lockout mechanism though). Really cool to watch - they scored second in the "design innovation" category of the design competition. (Shameless Plug: we scored third in that category). A big deal with this leaning trike from Arkansas, the started DESIGNING in January! Believe me when I tell you - that is HUGE progress to make in such short time. On top of that -- almost all of their team members are getting married soon (their finance's must be VERY tolerant) and there's only something like 4 or 5 team members! I was really happy to see someone bring a leaning trike -- I give them a tip of my hat ;) Fourth Picture: This is what a high speed streamliner resembles -- note the landing gear (very awesome idea). They had some "knarly" crashed today involving hay bales, skidding and mulch (at the sprint event - more on that later). But, true to their safety claims -- no injuries. Fifth Picture: Probably one of my favorites at the event - Tadpole trike tandem (for people that hate each other :p). I want to test ride it (and they're cool enough to let people do that too!). I also say their frame is one of the best design wise (appears very stiff). Last Picture: Everyone listening to the official before the sprint event. Max speed (by that red streamliner I believe) at the sprint event today was 41mph (male rider) ;)

What profile of pole would be torsionally rigid? Answered

Calling all mechanical engineers and physicists. I want to make a pole that can resist twisting forces. The application is a down tube on a bicycle frame. And I want to use bamboo because it's light, very strong, very cheap, and biodegradable. The problem with bamboo is it lacks torsional rigidity because its fibers only run lengthwise. I was thinking of wrapping a bamboo pole with a composite fiber (hemp and glue) at a 45 degree angle like they do with carbon fiber poles but maybe a different shape would be better. Can anyone think of a specific geometry of pole that is tortionally stiff? I noticed some bicycles have a triangular down tube. Maybe if I cut bamboo into three strips and glued them together into a tube with a triangular cross section, this might be less twisty. Am I thinking along the right lines here? My first bamboo bike has a lot of twist and this might be one way to make it stronger. Please let me know what you think. UPDATE: The issue was many fold. The short answer is Tonkin Bamboo is the species to use for bikes. This is what most people seem to use. Also Boo Bikes use dendrocalamus strictus (aka Iron Bamboo). My frame had some cracks possibly due to harvesting at the wrong season. I've recently gained more cracks and the bike flexes even more. It flexes like a noodle but I can still do an endo no problem. Go figure. Also hemp sounds like it gets more stretchy after being flexed about 1000 times whereas carbon fiber stays stiff. And squishy wood glue is probably not as stiff as epoxy. All this adds up to a flexy frame. My next one will be tonkin bamboo but I will try hemp and non-toxic wood glue again. UPDATE #2: I'm making a three wheeler and my engineering design teacher gave me some advice involving spaceframes and triangles. The plan thus far looks like this upright tadpole trike: UPDATE #3: I think I've got it! Instructables sent me a box of K'nex and I built up a model of a standard bike's frame. The thing is, when a bike frame twists, the opposing corners of the trapezoidal shape come closer or further apart. So a deep X brace from corner to corner seems to fix most of the problem. I'll try to post a youtube vid of what I mean soon.
