'Axe as RC speed controller

Would it be possible to connect the output from a RC reciever to the digital input of a pcaxe 28x1 board and controll the motor outputs?

Of course it's doable, that's not really the question. But does anybody have any thought regarding it? Has anybody done it? I presume the signal out from the RC reciever is a standard Servo-signal. I know CtCpassed a signal from a RC reciever through his 28x1, but I don't wanna controll servos,I wanna controll a couple of DC motors.

 

Good deal on rc tank w/built in video cam.

Hey all.

currently amazon has a damn good deal on an rc tank with built in video camera. On the amazon search, look up spy gear. you should find the atv 360 for 51 bux(as of apirl 19th). This thing usually goes for about 130 so imo it's a damn good deal.

I bought the the spy video car($50 as well) a while back and managaged to pull the camera gear off. The stuff is pretty cool for the price. I'm still working on the car, but figured I'd grab this tracked version as well since it was a good price.

USB to RC pulse controller

Hi, new to these forums and hoping someone can help me out!

I'm building a robot submarine (ROV) for fun on a pretty tight budget. The robot will have an on-board PC (in the form of a micro-ATX or nano-ATX motherboard) and will be controlled down a tether wire.

GRemote

This is my first attempt to make a custom remote controller, and also my first customized Arduino.
After seeing this post made by ObbBot I wanted to try to make one myself.

I figured that if I purchase one remote controller it would be cheaper than buying two of these and paying shipment to Portugal.

So, ripping the guts from a game remote controller I get two joysticks, a couple of buttons, two nice motors and one small lcd.

Since I started messing with robotics that I wanted to build a tank, and finally that moment arrived when two Tamiya thread kits and a Twin Motor Gearbox arrived. … Read more

RC RF directional beacon

I am still wondering if it is possible to create a simple, cheap, fairly accurate, directional beacon for outdoor use. And I keep thinking I should try to re-purpose an RC transmitter. So here it goes:

Would you deem it possible to create a directional antenna for an RC transmitter?

Would this antenna be able to rotate? Fully continous, or just 360 CW followed by 360 CCW?

Which RC system would you consider? There are so many frequencies in use. And modulation types.

I have this thing in the back of my mind that "the next step" for me must be my robots talking to each other.

This is my first experiment working with the XBee modules, and I thought it would be cool to control Farrusco. So, … Read more

Are RC toys a good source for servos/motors?

I was wondering whether RC toys are a good source for components. I came across a RC plane with two motors and two servos that only costs 25. This seems like a very good deal to me, or would this be a bad idea?

What are your experiences with demolishing toys for the greater good, or do you have an alternative cheap source of components?
