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 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!

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.

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,

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.

(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.

I'm working on a little project that would require a very, very small transmitter/receiver combo, that needs to be both small and battery operated on 1 channel. I seem to remember some product that did something like this, kind of a secret message toy or something to that extent where when the button was pushed on one it would turn the light on in the other, so you could signal each other from across the room or something to that extent. I really just need a micro micro receiver that's linked to a 1 button key fob remote. If anyone can point me towards that product or a kit or what have you, lemme know! thanks!

whats the best motor and ESC to use for a high torque r/c tank?

I am currently building an r/c tank, but i am having trouble finding a suitable motor and ESC that will allow it to go realy fast ( high speed tank). all i can find are brushless motors that require 30A at 6-12v, the same goes for the esc's, and i have no idea were to get that sort of power as i only have access to a 9.6v 750ma battery but i can get sealed, lead-acid batteries, at around 12v and 3amps, but thats still nowhere near what i need. does anyone know where i can get a brushless motor that can have at least 30kg of torque @ at least 1500rpm, that can run off 1A 9V?
