K'nex Car

My vehicle for the TNKIT. If you're gong to ask about the front wheels, I didn't have enough tires. And if it makes a difference, this was my first vehicle too.

Flywheel car

I've seen some old flywheel powered toy cars and i'm wondering could that be scaled up to work on a pedal car so that it spins up while you're pedalling and then have it engage by lever or something to assist pedal power over bumps and stuff or just give it a boost on the flat? also most flywheels seem to be mounted vertically, is there any reason not to mount one horizontally as i think it would fit into the pedal car better that way?oh and assuming i'm limited to a certain weight would a small flywheel with an evenly distributed weight or a wider flywheel with most of the weight on the outside edge maintain its spin for longer?

Slot car racing - controlling the cars wirelessly

Guys, I and my two boys have a Tomy AFX slot car racing system that we set up and play. We have a load of track so we can set up a long, winding track. The downside though, is that as the speed controllers are connected by a wire, when one of the cars comes off, you have to go over to put it back on the track and one of two things happen; 1) you have to drop the controller, go over to the point where the car comes off, then run back (Me) or 2) run over to where the car has come off, forgetting that the controler is still connected to the track and pull the track apart (the boys) If there was a way of making the controllers wireless, it would be brilliant. It would mean you could stand where you want and not have to waste as much time when recovering your car. As i see it, I would need four independent transmitters, of one channel each. That's about the limit of my knowledge of the wireless bit! The cars get about 22 volts, although clearly the current is not massive. The current controllers are basically a rheastat with a trigger connected to the wiper that contacts the coiled resistive wire. Any of you clever guys out there know of a relativeley cheap and simple way of making this wireless?

Securing a Car Door

I have a car with a mechanical door lock that is broken. Hence I cannot lock the car door (drivers side). I tried to stick a couple of staples (from hasp and staples) using superglue to the door and body work with the idea of putting a padlock through both. To my surprise the superglue would not stick. Has anyone any idea how I can secure the door while the lock is broken. Thanks

New Knex Car 2

I know how to make a car that has two mini block trigger gun on the top that shoot off while driving on its own. With the use of a non strechy string. Lets say you have about 16 in. of string. And you put the two guns in the back of your car.You can wrap one end of the string to the block trigger gun's trigger(that sounds wierd). and the other end of the string to the back rod that has the back wheels. When it starts to go the string will begin to wrap around the back rod until all the string has been used. The string begins to get tight. For the car to go any further its gotta pull down on that string, so it pulls it down and the guns fire. DISAVANTAGES: 1. Right after it fires the car cant travel any further. 2. Probobly a pain in the butt to reset. 3. Not sure if it fires that far. 4. I havnt even finished it yet, so im not sure if it even works. ADVANTAGES: 1. There hasnt been any thing like this posted before. 2. It can have up to like a lot of guns. Thank you for reading this forum. I hope you understand. I dont have any pics for 2 reasons: 1. Im on vacation. 2. Its not finished yet. If I have any mispellings please tell me and I will fix them.

Remote Control K'Nex Car

Hello, K'Nexing community! It's been roughly three years since I last posted anything on Instructables. Anywho, I've finally gotten the motivation to create something out of K'nex, and also combine it with my favorite hobby of hobby-grade remote control cars.  This car that's featured would be a brushed, but also fast on-road cruiser. Features/Notations of vehicle: Powered by: 12T or 15T Brushed motor ESC: Old ESC from ECX Torment, or Traxxas Slash ESC RX/TX: Team Associated combo Servo: Team Associated servo Solid Rear Axle Power Source: 2S LiPo More details and pictures will be added over time, and hopefully it won't take another three years. XD I've also included a couple of pictures of my current RC cars.

Cars running on vegetable oil regulated

The man is really bringing me down here...Drivers of SVO (straight vegetable oil) fueled cars are running afoul of the law.Not too long ago, cars that ran on leftover vegetable oil were rare, a curiosity. But now that lots of people are buying kits and hiring mechanics to mod their cars to run on french fry juice, the government is starting to take notice. Drivers of these cars now have to pay the same taxes as traditional fuel drivers, register with the state, file monthly reports and payments, as well as make sure they are in compliance with local environmental laws. Noncompliance will be punished with stiff fines.
