How to redirect Bicycle chain?

I'm working on a [secret] project that involves a recumbent bicycle. I'm going to have to use a long, tandem bike chain. The problem is, the pedals are going to be mounted at approximately a 32-43 degree angle to the rear axle, with an obstruction (me and my seat) in the way. Is there a way to some how redirect the chain, so that it would go under me? Thanks!

68 Camaro Help

So my Dad's Birthday is coming up and I want to get him his high school 68 Camaro Z-28. He was selling it (or so he thought) to a Mark T Reese, wife Janet living in Mobile, Alabama. My dad lived in California. Mark said he didn't want to buy it. He offered to sell it for my dad and since he already bought plane tickets, rented a trailer for the Camaro and was in Arizona on his way, so he accepted. So he went and dropped it off and came back to California and never heard from him again. I asked my dad the VIN but because it was a race car so it didn't need to be street legal so carfax is useless. He bought it in 1979. If anyone happens to know how to find it please let me know. Thanks.

Quick! Stop surfing, it's gone main-stream.

I don't surf (that's the North Sea out there!), but I can see the attraction. Unfortunately, so can the DINKYs - surfing is turning as cutting edge and "street" as golf.Apparently the latest wave of people into surfing are so rich that estate agents have found a significant niche market - people buying property to store their surfboards!

Tour of the Largest Private Collection of Military Vehicles

Through the MIT Club of Northern California, Christy and I got the chance to tour the Military Vehicle Technology Foundation's collection in Portola Valley. Seeing 100 tanks from different time periods lined up and seemingly ready to roll was pretty amazing. I've always had a thing for half-track vehicles, and was especially pleased to see a half-track motorcycle (SdKfz 2 Kleines Kettenkrad). In all honesty, this is probably one of the most impractical vehicles ever created, but it just looks so cool. My other favorites to see in-person were a SCUD missile launcher (SS-1b Scud A) and an M48A5 AVLB (armored vehicle-launched bridge).They also have a large shop where they repair, rebuild, and often re-engineer parts to restore the various tanks. While I was there, they were in the middle of repairing a World War II-era German tank found in a river. The collection is the hobby of Jacques Littlefield, whose father, Edmund Littlefield, amassed a $1.7 billion fortune by running the family construction and mining company, Utah International, and merging it with GE (more here at Forbes).The Instructables forums aren't exactly the best place to few 57 pictures, so here's my Flickr set, and here's the Flickr set of the person who organized the tour.

Trip Gauge

Hey, I was just wondering if anyone knew where I could get an inexpensive (used is ok) trip gauge to tell me real time MPG in my car. I didn't see much on ebay, and am not interested in spending $169 on a new one. I'm not sure the year of my Ford Taurus, but I can check tomorrow. Thanks!

Fixed Gear/Track Bike Conversion

Hey guys. I just stumbled upon this group. Good stuff here. But lately I've been working on an old Schwinn Le Tour I have, and could you some help. I've stripped it down, cleaned it all up, but before I go and put it back together id like to find out a thing or two about converting it to a fixed gear track bike. It's got horizontal drop-outs, and in great condition. I just need some tips on how to do it, and opinions on the pro's and con's of the conversion. Thanks to everyone who can help me out.

DC to AC Inverting for boat

This spring I am looking to build a pontoon boat from scratch (Besides the pontoon logs). Its going to be a large boat and I am wanting a few amenities to go along with it. Im trying to figure away convert the car battery wich is on the boat to power appliances such as mini-fridge, lights, radio, box fan, and maybe a PS2 with Television. I need a high wattage out-put to power everything too. For sure: 8 lights - 75 Watts ea. 20 inch tall Mini-fridge - 200 watts Stereo - 150 watts Box Fan - 120 Watts Maybes: PS2 - 180 watts 20" Television - 300 watts I want this to work if all the for sures were going at once. I want to know how many car batteries I will need approx for 10 hours (or longer) of use with the "For Sures" And I want a clean way of doing this. Any advice would be much appreciated!

LED Bike Turnsignal

Hey everybody, this is my first adventure with soldering or LEDs, so hopefully it will go well. I'm planning on making a set of turn signals for my bicycle with two LED arrows which work at 12v, I'll power it with 8 AA and use one momentary switch for each. Does this all seem like it should work? Specs on each piece: arrows : "Mini Arrow Size: 1.50” x 1.50” ,Operational voltage: 12-14 Volt AC/DC" switch: "This momentary switch is perfect for short connections. Normally open and rated 3 amps at 125VAC."

Battery Pack or Car Battery - Biking

To all of you night bikers out there, do you power your lights with a battery pack of NiMh or Li-Ion battery packs, or do you use a lead-acid car battery? The weight of the car battery kind of turns me away from it, but I don't want to have to recharge my batteries every day. I'm looking to power LEDs and maybe halogens. Thanks!

How to fix a cars air conditioning.

Alright, so my sisters cars air conditioning is no longer working. She took it to a mechanic and he said the repair would be around 3 grand to fix, but understandably she would rater fix it herself. So, I am trying to fix it for her, but I wanted to know if there was a way that I can remove the compressor without pouring Freon all over the place?

vehicle vinyl application

I'm working on a large project with a deadline, and falling temperatures in the Northeast are influencing my work performance. What I need is a portable, efficient, and safe device and/or method that can quickly heat the outside of a car.I am working with temporary adhesive vinyl panels that are being applied to the entire hood and trunk of New York City taxi cabs. We can only apply these panels for about 2 more weeks, and we are trying to cover as many taxis as possible. The weather, however, has been slowing our progress. When the temperature gets to about 60 degrees F and lower, the panels become very brittle, almost like paper, and lose some of their adhesive properties. Application becomes very difficult. We're able to keep the panels in a heated vehicle, which helps a bit. But the outside of the cars, particularly the trunks, are too cold for a proper application. The hood can be easier if the engine has been running for a bit, because this warms the panel and restores its malleability.Does anyone have any suggestions concerning a fast, efficient, portable, and safe method for heating the coachwork of a vehicle? If you can't meet all of the criteria, the device and/or method must at least be portable. But I'm curious to hear any other suggestions, as well. I've come up with a whole slew of ideas that are plenty fast but are in no way safe. Let's face it, though, they're still fun to think about.Any help would be greatly appreciated. I have faith in the creativity of Instructablers! And think of it this way; your help can contribute to a really excellent project. If anyone would like more info, gardenintransit.org. Rock on.

Electronics

Http://www.taskled.com/techbflex.htmlI wonder if anyone can helpI want to make a bike light using CREE leds (*4) and have spotted the bflex (see here - http://www.taskled.com/techbflex.html - I was going to go for the UIB2 version) as it has battery monitoring facilities built into it. You set two voltage values v(low) and v(med). There's a connection on the board V(stat). S is the voltage from the battery.V(stat) = 0 if S is higher than v(med) => State 1V(stat) = 3.3V if S is between V(low) and V(med) => State 2V(stat) = alternates 0 and 3.3V between 0V and V(low) => State 3So I was thinking (of displaying this via 2 LEDs (green and amber))State 1 - green on, amber offState 2 - green off, amber onState 3 - alternating between green and amber.I was hoping to combine the LEDs into one bicolour LED. If anyone has any cunning plans or improvements they'd be appreciated.. whatever it end up with though it mustnt use up too much battery power.

Air ride bicycle suspension

So i've been interested in pneumatis for quite some time and recently I came across a small air cylinder (6 inch travel), 12 volt air compressor, 12 volt valve, and misc fittings. I got really excited and without thinking twice I grabbed tools and started hacking up my old beach cruiser (it was quite a mess anyway after 3 trips to burningman). So this is the outcome... I can control the up/down with a momentary on switch out back. Now just looking at this mess its easy to see that well i obviously can't weld. Never tried... Anyway it rides really sloppy as you can imagine, much like an old Lincoln with the shocks blown out, but it is so much fun! Now i pose the question to you community members, how would you have done this different? Looking forward to your responses!

Wood Converted SWB Recumbent Bike of Awesome!

This is a project coming soon... But I'm so excited I have to share... I'm beside myself in excitement, in fact.All that's left to finish the project is:1. Recondition a bit more chain and add it on2. Add idlers and get my chain line in order3. Cut excess wood and make a SeatBut after I assembled a crank into some 2x4's - and had to step back and laugh. I've seen it before, in person at the maker faire. But to do it myself and see how easy/simple it is... Ha!So I cobbled that together - made a pseudo tie fighter handle bar from some scrap PVC and two Tees... And rode off into the sunset... Until the chain derailed - and then I realized I couldn't make appreciable low speed turns due to chain routing... Both problems can be fixed with an idler - a solution I've yet to install due to Kinematics homework having a due date of tomorrow.So yeah, this is something I've always wanted to do. And I'm totally happy I did it (and happy I bought those cheap bikes at auction last year :p). AND, the front boom is modular. I intend on making it, and have accommodated for, adjustable. So I can go for more incline and a more aggressive seat position. (mind you, this is a single speed :p).Okay, I'm done venting -- feedback?

Im trying to figure out how to guage how much throttle im applieing in my car. I want to have a set of lights or even just an analog guage that tells me for example that i am using 25% of my throttle. I was thinking of putting some sort of pressure switch under the gas pedal, but Im stuck on where to start. Thanks, Newman

Car Camera (security) system

I've had my car knocked into when parked and could not find any witnesses to the incident. That set me out into the market and internet to find a camera system that can record about 12 hours when I am away from the car. Unfortunately, every system I've come across is a "black box" system. It records moments before an accident so you can have evidence. Anyone knows how to build one?

Working with pneumatics

Anyone know how to setup a simple air system? I have a pneumatic air cylinder with dual 1/4 inch NPT threads and a 6 inch throw. Ultimately I would like to have the cylinder extend when I flip one switch and release/contract under weight when I flip another switch. Think automotive airbag systems. Anyone know how to wire or plumb something like this up? Ultimately a compressor only option is what I'm looking for as a air tank would add too much weight. Any help would be greatly appreciated! Thanks
