Getting laptop to stream to ecm in car

I bought a car battery just so I could take it with me camping and charge my cell phone. Here is the problem: car powered devices are designed to be charged in a car while the car is running. The voltage of car power is 14.4 volts and the voltage of a fully charged car battery is 12.6 volts. The car battery will charge my cell phone because it is low amperage and does not drop the voltage very much (only if the car battery is mostly full), but if I try to connect my inverter and power higher-amp devices the inverter will beep and not work because it senses low voltage. One way I can get my battery to work is if I had a DC step up transformer. A car battery ranges between 0 and 12.6 volts. I need something which can supply a constant 14.4 volts as the battery is drained. Another option is if I got two batteries and hooked them together in series for 24 volts. If I did that I would need a transformer which could convert 24 to 14.4 volts as the batteries drained. So what is the best way to do this? This is for my camera drone: a DJI Mavic Air. If I could charge my drone batteries with a car battery I could fly a lot longer. Thanks-Jacob

No, not a phone in a car--a phone that is a car, or at least looks like one. This car is a converted VW Beetle that is being used to promote a phone company. I think this may be even more exciting to see on the road than the sheepdog from the movie Dumb and Dumber.Link via TechEBlog

Http://www.hulu.com/search?query=Thunderbolt+And+Lightfoot&st;=0 I just saw this movie and there was much debate over the make of this car. Granted the link is a dark picture, but at 1:30:24 and 1:35:33, there are some shots of this car. If you could kindly take the time I'd be most grateful....... not to mention you would settle an argument. Thanks

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! :)

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?

From a NYTimes article, a story about a new $2500 car hitting the market in India. It won't pass US or European emissions or safety standards, but still- how neat is this?For Tata Motors of India, which will introduce its ultra-cheap car on Thursday, the question was, what could it take out?The company has kept its new vehicle under wraps, but interviews with suppliers and others involved in its construction reveal some of its cost-cutting engineering secrets â€” including a hollowed out steering-wheel shaft, a trunk with space for a briefcase and a rear-mounted engine not much more powerful than a high-end riding mower.The upside is a car expected to retail for as little as the equivalent of $2,500, or about the price of the optional DVD player on the Lexus LX 470 sport utility vehicle.The model appearing on Thursday has no radio, no power steering, no power windows, no air-conditioning and one windshield wiper instead of two, according to suppliers and Tataâ€™s own statements. Bucking prevailing habits, the car lacks a tachometer and uses an analog rather than digital speedometer,

When I tried to start my car the ignition just clicked a few times, then finally started. It seemed like the battery was weak. I spoke to a mechanic who said probably one battery cell was bad and advised that I replace the battery. I did that and now have a brand new battery. I didn't fix the problem. Does anyone have advice?

First off, this is a question about speakers sound quality loudness and all that stuff, it doesn't really have to do with any math or equations, just experience. So I want some sub woofers, and after looking around I have determined that there are cheap ones, and very expensive ones. Now, if I get a fairly affordable 15" (med quality) will it be louder/better than a 12" one that costs $900
Question by jj.inc | last reply
What I am designing (and planning on working on very soon) is a vehicle with the possible speed of a gokart, but with a propulsion system similar to a bike. The mechanism itself would be a simple push pedal (like a car) but with a gear system like a bicycle. Upon pushing down the pedal, a shaft connected too it would then push against the foremost gear. and that gear would push another and so on until it comes in contact with the rear wheel, propelling it forward. A simple spring between the pedal and floor will allow the pedal to return to the original position. However I cannot seem to get the steering and brake system down right. Should the steering be that of a car and use 2 wheels on the front with a long axel connecting the 2? or more like a bike, with a one wheel turning system. (aka. should it be a 4 wheel or 3 wheel? Might depend on weight distribution and balance, though both could be possible.) and how should the brakes be arranged? a pedal, like a normal car brake, or a stick beside the driver, like an emergency break, as well as where the brake pad would come into contact with the rear. On the axel or on the wheels? Last (and most definitely not the least) is that while this vehicle must be sturdy, it must also be light weight. So any and all material recommendations for parts would be greatly appreciated. (cheap would also be appreciated) (My thought for material) chasis - light, but firm (strong) wood. axels - aluminum or steel tires - Gokart/ riding lawn mower turning wheel/steering - wood or plastic seat - whatever I can find that's soft (not a major thing) safty belt - I may not be able to test out the prototype (kinda thick) so I need the crash test dum *ahem* "driver" to survive incase a crash were to happen. brake pad - rubber so that it causes the right amount of friction but not enough to damage any parts.

Ok i want to build an electric hybrid system my first question is ac or dc power. i want to build a paralleled drive system. that uses the stock motor to drive on the highway with maybe a little help from the electric motors. here are my thoughts start with a f250 powerstroke diesel crew cab truck, install a divorced t case and new drive shaft, hook the electric motor to the t case front axle output. the goal is to use the space by the tool boxes to fit the batteries and later update the alternator. the goal here is a hybrid that can still haul what a normal truck can but run purely on electricity when in town

Hi, So in computer engineering I've got to make a arduino based car, I've added a whole bunch of features such as IR tracking, obstacle avoidance(proximity sensor), optical tracking(follow a black line), and remote control through an android based phone. Since I'm a total newbie to technology I'm having trouble. I would appreciate it if You guys can point me towards resources and arduino libraries(for coding) that will work for me. Right now for coding I've only got basic pseudo-code setup since I do not know what libraries to use. I have searched up many sketches online and looked at them but didn't really understand any of the code. Here's the basic pseudo-code I got setup on the things that I've got to work on: DC Motor (4 of em for the wheels) (I also plan to add a stepper motor for turning right and left so if you could direct me on that as well) //Import necessary library //Setup the motors and pins //If signal for forward received //Code for moving forward //Set speed //Else If signal for backward received //Code for moving backward //Set speed //Else If signal for right received (keep turning right till stop signal received) //Code for moving right //Set speed //Else If signal for left received (keep turning left till stop signal received) //Code for moving left //Set speed //Else If signal for stop is received (Should we slow down to a stop or just stop?) //Code for stop //Set speed IR (I've got transmitting and recording diodes) //Import Library //Declare Pin for the IR Sensor //While loop: Move Right //If IR signal is received //move forward //Else //Jump back to top of loop Proximity Sensor (obstacle avoidance mode) (I might either use the one from Lego kit or buy a separate one ) //Import Library //Declare Pin for proximity sensor //While Loop: Send out sonar(echolocation or whatever) every second //Is there any obstacle? //Yes, turn right so many degrees, and go back to while loop //No, move on forward at set speed //If you’re surrounded and cannot exit send out a message through flashing LED's ________________________________________________________________________________________________________ I'm not asking for the code or for any of you to do all my stuff for me, I'm just asking for direction and resources. Thank You

Hello Friends, Car donations can be a good source of added income for many non-profit organizations. What amounts to a tax write-off for many dealerships can be turned around and sold so the charities can increase their ability to help their causes. If you are interested in getting an automobile donation, asking a dealership to donate may be a good option. Calculate all the facts and figures before you even contact a dealership about getting a donation. Car dealers are traditionally bottom-line oriented people. This means they understand numbers well. If you can show what your operating budget and expenses are and how a donation can be a financial help to you and how the tax break will help the dealer, you will be better off. Best Regards Tim Boon Donating Cars

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?

I was thinking about building a flying car that would have most wingspan hidden under the car (pops out when activated) and the doors would be the tips. (What used to be the back doors would roll over van-style, and the back would otherwise be covered by sheet metal) In the back, there would be two vertical rudders and the spoiler would be cut into flaps for horizontal rudders. The thing would overall be powered by two helicopter jet engines. Once the flight system is activated, the gear shift (auto trans) would turn into the throttle, and the gas/brake pedals would turn into the rudder pedals. The idea is to make a flying car that still (when wings are stowed and trunk cover is closed) looks like a normal car. The question: is this possible?

Via Notcot, and because I've been looking out for this sort of thing recently (Roger-X is deciding between design-related university courses), I came across a Kickstarter project called I Draw Cars. It's a pair of guys, design graduates, who have put together an automotive design resource in a moleskine format - industry references, event data, and templates over which you can sketch your own ideas to form part of your portfolio. It looks good. Certainly the concept is sound. I wonder if others would think so? --------------------------------------------------------- On a related subject, whilst visiting Wales, we landed in a design exhibit at the National Waterfront Museum in Swansea. Projects were on display from students of the School of Industrial Design in Swansea. I could go through them, but they were all fascinating - everything from a pop-up cup-carrier to a collapsible zimmer frame and a hydroplaning sports car. Instead, I'll list our highlights, in no particular order: An interesting take on wheeled luggage. A "hyper amphibian". A Dyson-branded scooter. School bookshelves. A cool take on Landrover. Hydroplaning yacht. A hotrod. There were others, but they did not display their websites, or have a small pile of business cards for folk to take. That's their loss, since part of their course covers "self promotion"...

Question | last reply
She bought the car about two weeks ago, and it ran great for exactly 5 days. Then it started shaking and making strange noises. She took it into our old high school auto shop for a diagnosis, but a student disconnected the battery while it was hooked up (to clean the terminals) and we lost the diagnosis. The instructor informed her that it would take a few days for the engine maintenance light to come back on, and to come back if and when this occurred. Well it did- exactly 5 days later. We are pretty sure it was reset the day she bought it so that by the time the problem arose, it would be "her problem", but can't prove it. I'm pretty sure a catalytic converter does not constitute a safety issue, thus wouldn't be covered under her certification. Is there anything she can do, is she on her own?
