R/C

Hi, I'm making plans for a remote control car from scratch, and have a few questions. Are hobby motors able to go backwards, how do you control that? Any ideas on making a wireless usb cord for a webcam? Do you know of any small things (like motors) that could move a switch remotely for the steering mechanism? Any other ideas?

R/C Sailboat

I want to make a R/C sailboat, so far I have 4x32x1/4 inch balsa wood planks and they should last me the entire project. This weekend I'm going to visit a hobby store and get: waterproof wood glue, waterproofer for the wood. Then go to target and get a rotary tool. The boat will be 3 inches tall with a 1 inch keel (keeps the boat from tipping) 5 inches wide and 15 inches tall. I will get a cheap multi directional R/C car and use the steering mechanism to move the rudder and the drive motor to turn the sail. Once I make the boat I'll fill the gaps with wood paste and water proof everything hopefuly with a silicon based sealant. Any tips or flaws with my plans, please see the attached sketch.

Commands needed in R language?

Hello everyone I hope that you are fine. Because I am starter, I am facing difficulties in figuring out commands that do the following: Find the sample mean M and sample standard deviation S Build the histogram. Find if the shape of the distribution is close to normal or not. Add to the histogram plot the line corresponding to the probability density function of the normal distribution using obtained mean and standard deviation. Set up a 95% CI for the sample mean, using your values of M,S and N Use the temperature (tempc and tempf) data given in the excel sheet. You can download the excel sheet from following link: https://app.box.com/s/8uw6os46iibmx4n5t21q Kind Regards raishikoh

Replace r/c batteries

Hi, does anyone know how to replace r/c car batteries with normal AA cells (or pp3 or whatever)? This is really annoying me coz I have an old r/c car (pretty good one actually) but the battery has died and I was wondering how to replace it (or 'refresh' it if this is possible, which I don't think it is...). It would also be helpful to know a technique for finding out the voltage/amperage of the old batteries so I can fix it without blowing the electronics. Pictures would be attached but the uploader isn't working right now; I'll get them up as soon as possible. Thanks guys,

Mod a mini R/C?

Hey all, I recently started looking into modding some of the stuff i have lying around and I came across an old mini r/c car that are only about an inch long. (see photos) Anyways i got down into it, but I really don't know what I'm doing, i was just wondering if anyone could come up with a mod for it. so far I've managed to hook the little r/c car to a plug so that it had a constant electric supply, which kinda defeats it's purpose, but was good to figure out anyways I thought. Thanks! (despite the fact I googled for the image and took one of the first 5, this actually is the exact model I have. surprisingly convenient, thanks google!)

R/C Car Robot

I have an old rc car that i wanted to make into a robot for my graduation project. I want it to be able to sense a possible threat (wall, tree, person, other car) and be able to drive without help of a remote control. I have a NXT Intelligent Brick (meant for Legos) it has a 32-bit ARM7 microprocessor. Support for Bluetooth wireless communication. 1 USB 2.0 port. 4 input ports. 3 output ports. Powered by 6 AA (1.5v) Batteries, not included, or lithium Rechargeable Battery (#9798), sold separately. Up to three NXT Bricks can be connected at the same time; however, you can only communicate with one NXT Brick at a time. This is the individual component, and does not include any sensors, motors, cords, software or other accessories; for the complete LEGO® MINDSTORMS® NXT set, please see item #8527. Do you think it is possible to get it to work? Also if you have ideas please tell me.

R/C Drift car from scratch?

Hi Everyone! I happen to just have bought a very cheap and very disfunctional R/C Drift car. I am now thinking of either making one from scratch or modifying my present one. If you're an rc enthusiast, arduino programmer, electronics hobbyist, or just someone who happen to have some spare parts that you don't need that I may need, feel free to say something. My present Drift car is ,btw, a Flash and dash Race tin. It has two sets of wheels, one for drifting, and the other for racing. I am unsatisfied with this because it always swings its back like this http://www.youtube.com/watch?v=AR8wg24AyJI  Look in 0:32 to 0:34. Its bad enough that I don't know how to drift. Please feel free to comment ,suggest, or give a tip so I can mod my present one or make another one with variable speed and turn. My present one doesn't allow this.

Autonomous

I originally posted about converting a John Deere Power Wheels tractor to remote control powered through the RPi. I decided not to for various reasons. Time was one of those reasons. Now, I have been able to come up with a large scale electric remote control vehicle. I'm looking to hook that up in a collaboration with the Raspberry Pi. I have some ideas but just wanted to get some opinions and maybe even a difficulty rate as for as programming and so forth. Any help will be much appreciated!

The estimated weight of the electronics is two kilograms. 4. The estimated weight of the fiberglass for the whole plane should be around four kilograms. 5. Plane will have twin rudders as well and most likely be a belly landed. I also need help on props, engine power, and wing diameter. if I need to specify anything please ask. many thanks    Zach

Erase a dvd+R using software

Ok so we all know its possible to write a dvd+r up to the limit. (one time only of course) So if it can write data once, that why cant we have it ignore the data or headers and just write all 1's or just random garbage to the disk to destory it? It actually sounds cooler than breaking it... If there is software than please provide a link (if its free/open source)

Help on R/C plane workings

This is my first time on the site and first time with trying to build a rc anything.  My mind is so scrambled due to constant searching online and I still don't know where to start. First, I thought of building a brushless motor.  Seeing some online looks awesome.  Just some wire, rod and a magnet to a battery.  But I do not know the size of battery nor  how the size of the wire will change my project. Second, it would be fun to have my PS2 controller, control the heli or plane I choose to build. Is this possible. Third, can I use a motor from a cheap heli in a plane and have control over the speed? Lastly for now, is there a way to figure what motor I need if I was going to build a slow flyer vs a outdoor micro flyer?  I have been looking at weight mostly and don't know if I need to be that concerned. Please help if you dare to take me on as a challenge case.

Can I "upgrade" my Nikko Electric R/C Hummer H2 with a couple of 9 volt batteries without blowing anything?

I have seen a Mod of an Airsoft pistol from Wal-mart that pretty much applied three 9 volt batteries, and it was able to shoot farther and faster and I was wondering if it can be applied to a Nikko Electric R/C Truck the same way. It currently runs on a 9.6 Volt Battery. And I would like to see if there are any precautions or additions I should look into before applying a few 9 volt batteries. Just so I don't blow any circuit boards or anything else. Because like many Americans... we just want everything to go faster. Thank you

Polarity switching issue, first one to resolve gets a one year pro membership, if answered by June 03 2012? Answered

Ok, here's the issue.  years ago i picked up a wireless remote control kit for automotive use.  It consists of a 12v receiver with 4 sets of colour matched wires.  Basically you can turn on and off 4 devices.  Press button 1 on the remote and a on-board 15A relay activates completing the circuit for one set of wires.  Press button 1 again and the same relay cut outs and the circuit is broken.   These wires are designed to interrupt the negative or ground  side of your accessory with the positive lead hooked up to your power source.  The receivers power is hooked up to the 12v battery.  I even went so far as to open up the receiver and discovered the entire circuit to be potted in opaque epoxy (how rude) so no modding of the circuit sadly... What I can't get my head around is how to utilize this as a polarity reversing unit, or can it.  Now I have messed around with using polarity reversing circuits in a analog style before, I even wrote an instructable on making one with a DIY DPDT switch  Here's the thing, I live in a remote area of the world and do not have immediate access to what most people are used to, so is this circuit possible to be utilized in the manner I am wanting?  I have access to additional standard 4 pin relays if this helps, but not much of anything else. First person that provides a detailed anwser, which results in this working the way how I want, utilizing what I have, by the end of JUNE 3 2012 will receive a 1 year pro instructables membership.  With a possible 3 month pro membership to the one who proves most useful in finding a feasible work around by JUNE 5th 2012.  And sadly using alternate supplies is not an option, "pretend I am on the moon, with no transport available in time". see the pics Note: in the diagram, the green wires are one switch, the blue wires are another.  Their are 2 more sets of wires but these are being used to control other items and are not shown.
