Car remote unlock modding.

Im talking about the little button remote you have on your key chain that unlocks,locks and opens your trunk of your car. I want more information on the system. Is it hard to remove?  If i remove it is there a way to mod it so you can open and or shut and lock doors to your house? Seems a shame to let me little remote go to waste =)   thanks in advance.

EMP for cars

So, if cops had a thing to shoot at cars, that sent an EMP through them, would it turn off the car? Would it harm the people in the car? Is it a ridiculous idea?

Conceptual Car

If you could invent any kind of car, what would it look like? What makes this car different from one you could just buy? Can it turn into a boat? Can it roll like a ball? Is in powered by bycicle pedals? Can it fly? Describe your car.

Car Air conditioning without Engine Running

Thinkin of running the AC from batteries at times I don't have the engine running. So- electric motor rather than direct drive from engine? How long will battery last? maybe need to have a second battery for this?

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?

selfcontained electric car?

I had a few ideas on how to make more efficient cars. First off why is it we have NO generators being used while stuffs rotating. Take a small generator with a rubber drive point...like there a chain or belt would go... and place that on the tires. This is a friction driven generator which means that it would not work well in the rain. These...if done right... could keep the car running and then keep the battery charged. Using the battery only for stops. I also think we need to figure out a way to put a coil in the drive train somewhere. Making it to where when the car stops the coil is wound tight, when the car takes off again the coil could unwind and help the car take off. this feature added to gasoline engines would help cut the cost of gas greatly, not to mention emissions.

Students Build Car that Gets 2752.3 MPG

Students at Cal Poly have made a car that gets 2752.3 mpg. It has three wheels and moves one person along at just 30 mph, but it can drive most of the way across the U.S. on one gallon of gas. "The 96 pound car has three wheels, a drag coefficient of 0.12, a top speed of 30 MPH, and a modified 3 horsepower Honda 50cc four-stroke engine. It originally clocked in at 861 MPG and has been continuously tweaked to achieve the mileage we see today." Link

Car Alarm

I just had an idea.... Someone needs to make a car alarm app for smart phones. It can use the microphone to listen for breaking glass, the speakerphone for playing pre-recorded messages (step away from the vehicle, the police have been called), the camera can sense movement inside the vehicle and the GPS can sense (and report) movement of the vehicle. All of this information can be sent in real time to the other phone that you carry with you. Installation is as easy as turning it on and tossing it in the seat! Compatible with any car! Battery backup! :)

Good new car

Hello boys and girls I have been saving up my lunch money for several months and thought about buying a new car. (my mom gave my car away to my nephew). I want something that is cheep, gets good gas mileage and preferable not made in the Republic of Korea (no Kia or Hyundai for personal reasons). I thought about a hybrid but they are like 6 grand more expensive and the advantage of MPG doesn't really justify the cost. I figure i can spend under 20,000. but i only make about 1 grand a month (take home) but i dont know how much insurance is going to be (probably expensive because im under 25) Or should i get one of them "pre-loved" cars at the dealer. Any suggestions will be greatly appreciated. (i thought about getting a bike but its not really a family friendly vehicle.

Car Audio Kludge

I recently bought a used car. It has a radio, but no faceplate. While I could probably find a replacement faceplate or even install a new radio myself. I want to see if I might be able to DIY my own stereo out of the bits of my radio I do have and maybe an MP3 player or something. I figure the amplifier and power systems are all hanging out in the box there. So all thats actually missing is the part that acutally makes the audio to send to the amp. Anyone out there know enough about car stereo to confirm/deny my thoughts on this and maybe provide some advice?

Come on people!! We have "PROS" saying it cant be done to 1st timers with excellent results. i've painted cars with spray cans (not recommended) of course I used Walmart cheepo paint, Tractor paint (had JD green, IH yellow, FORD white and mixed every thing together and sprayed it on my Toyota pu. mint green, lasted 5 years till I got tired of it. Then used Western paint Porsche red on same truck weathered badly after 2 years. Now I am going to paint my 93 Dakota with Rustoleum flat black and then get the grandkids to help camo it  with spray bombs,brushes, whatever. Just remember lifes short, HAVE FUN

Remote Control Car Controlled By Computer

I'm doing a project where I am rewiring a remote control car remote to work using a computer interface. I've found a few tutorials on how to do it, but they all deal with a "button" controller, where the motion is controlled by pressing buttons rather than using a "pistol grip" controller, or one with a wheel to control turning and a trigger to control acceleration and deceleration. Has anyone tried this, or does any one know if I would be able to use the tutorial linked below with this controller. I highly doubt it would work, but I would like a better opinion.http://jbprojects.net/projects/rc/

Cordless Car Heater

Hi all, I am camping in my SUV in northern CA. It's a bit cold at night and in the morning, and can stay warm with blankets and a sleeping bag, but, when I get up, and want to change clothes or just sit, it is really cold. It's a 1999 Ford Explorer V6, and I am trying to find or make a device that would heat the interior without turning the engine on.  I've seen handwarmers on amazon and ebay, but I don't see anything that warms that much space without a plug and without CO2 emission. Any ideas?

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.

12V car battery indicator

Hi, I have been trying to design a circuit to monitor my 12V leisure car battery, I'm thinking this should be fairly simple, but its been years since I did any real electronics. So the basic idea: Use the circular bargraph to indicate the level of the battery when a momentary push button is pressed the circular LED bar graph: https://www.sparkfun.com/products/11492 So the range of the battery would be something like 10.5V to 13.5V, there are 32 LEDs in pairs, so essentially 16. 1. So if we take the first LED pair, this should illuminate when less than 10.5V, so that should be easy, as long as there is some life in the battery it should illuminate 2. The next LED should only illuminate at the next step, 16 LEDs, 3V range 16/3= steps of 0.2V So at the following steps: 10.5, 10.7, 10.9, 11.1, 11.3, 11.5, 11.7, 11.9, 12.1, 12.3, 12.5, 12.7, 12.9, 13.1, 13.3, 13.5. So for 10.7V I guess I should use resistor before each LED. 3. The LEDs should light up after a momentary push switch is triggered, I would like this to be graceful, so the ring lights up smoothly one LED at a time as the voltage increases, I guess capacitors between the resistors and LEDs? This is the simplest way I can think of doing it, I have seen circuits which use a LM339 chip, but that can only monitor 4 voltages, perhaps 4 of these in series could do the job? http://www.electroschematics.com/7068/lm339-lm239-lm2901-datasheet/ I think this is the way to go rather than using inline resistor/ capacitor pairs? So I am a clear novice when it comes to electronics (but I'm enthusiastic), so if anyone can help me with this I would be more than happy to put together an instructables how to, something similar has been done before: https://www.instructables.com/id/Car-battery-tester/ In that example only one bar is lit, I want the other bars to stay lit. I can use Eagle to make the PCB diagram and get it printed, but I need to figure out what components I need and how to do it! Thanks for any help. Gary
