What can I use this little RC car for? Answered

Does anyone have a use for something like this? I was going to take this wee little car apart for the motor, but I'd hate to destroy it if I can still make something out of the whole body, the wheels and everything should still work. I think the little capacitor in there just went dead or something like that.

Well, the motor and wheel turning coils are still in-tact. I've removed the radio control board however, but I'm sure the board probably would run off 1 or 2 of these solar light panels (around 4.3v connected in series). Wanna throw me some ideas how to wire the wee little wires up in this car?

just connect the solar panel straight to the motor, since you took out the board if you want to solder to the wires, hold the wire over a flame, the insulation should burn off

I was thinking of soldering the board back in there, but the only question is, what do I do without a remote? I seem to have lost the damn things.. And it isn't one of those cars where the charger was built into the remote, it came seperate, so I have the charger and no remote.

do you have any other remote controlled toys? sometimes you can use other transmitters, on different toys

This is true.. Most cheap toys operate on 27 and 47 mhz or something around there anyways, and yes I have seen remotes not intended for other cars work. I'm afraid I don't have anything other than my Tyco Rebound

well.... you could go buy another toy car, with the same frequency of operation

Well considering how cheap they are, I will next time I stumble across one at the mall.

Try attaching it to a helium balloon and attach fans to the wheels. Kinda like a blubber bot.

hmm, too late I already ripped it apart, the battery was dead. My intentions were to hang the car on the wall or possibly just the motor, and put a colored wheel of some kind on it so I could see how windy it was outside without having to open the blinds. I have a question for you kiteman, and it's very urgent. How do I hook a capacitor up to this little wind turbine I made so that it only discharges into something like a led or motor when it's full? if I have it hooked up to an led, will it not bleed out current until it has enough to make the capacitor discharge and light the led?

You could try using a solar engine*. They trickle-charge a capacitor, then when it's full they dump the current through a motor or other load.

Replace the solar cell with a turbine (don't forget a diode to stop the capacitor spinning the turbine), and you should be sorted.

*It's a "BEAM" circuit. Check Solarbotics.net and click through to the circuit diagrams.

I checked that out, ironically for now I've settled with a "solar engine" out of a couple of my moms broken solar lights (they got broke off the metal stake part). Rather I mean the charge controller is what I'm going to try. Strangely the wind around here has been so god damn calm, I have had ABSOLUTELY no time (well a couple minutes of gust at a time, but does me no good when I get all my stuff out and then they stop spinning) to play with my little windmills and see what I can charge with them. *On a side note, I bought some balsa wood panels today and I plan to use them to make blades for these little motors. Are you any good at designing blade shapes??* I have the solar controller hooked up to one of my windmill contrations outside my window, but again, has not been windy the past oh I dunno, 2-3 days strangely. It does turn freely in the wind so I'm kinda quirked as to why I don't see it spinning all day. I think the most I'm gonna see out of each of these motors is 0.3-0.6v of power, but short circuited, the one I tested brought me in about 30-60ma of power, and that was spinning by the wind, not my hand. So while it may not seem like very much, I think it is enough to trickle charge some kind of battery, and with some testing, maybe this AA Nicd I have taped to the charge controller. It's a small simple pcb with a diode on the positive trace from the SOL+ (solar positive) and the SOL - simply runs to the neg of the battery. Ohh and one other question that has been bugging my mind. Say I get it rigged up to charge from these wind mills, which it should. What happens when the wind makes them blow backwards, or counter clockwise, obviously the polarity reverses (according to my volt meter), but will the diode rectify that or will it just block the power from going to the battery? Or will the negative on the motor switch to positive and start charging the battery through the negative terminal? I'm not sure, I've tried to google my way through all of this "experimenting" with small windmills to find circuit diagrams and other useful tid-bits of information but google just isn't on my side this time... Is it possible to get some of ya'lls msn addresses? That would be cool as hell if I could just talk to you without thinking of a whole message to write out or whatnot.

Charge controller, I have no help (Zach?)

Blades - the simplest is flat and angled to the wind, but there are loads of web articles about the airfoil section

If you're fixing the unit so that reversing is a poccibility, then you need a rectifying circuit to ensure the current always enters the battery the right way. But if reversal is a real possibility, why not mount things vertically and use a savonius-pattern windmill?

(And I don't do msn - chatroom type stuff confuse the heck out me. I need a minute or two's thinking time to get stuff straight before I type. Sorry)

>If you're fixing the unit so that reversing is a poccibility, then you need a rectifying circuit to ensure the current always enters the battery the right way. But if reversal is a real possibility, why not mount things vertically and use a savonius-pattern windmill? . Well it's not on purpose, but the wind direction does reverse sometimes, and as such I would have to assume that the blades would too? >(And I don't do msn - chatroom type stuff confuse the heck out me. I need a minute or two's thinking time to get stuff straight before I type. Sorry) Since when did msn messenger involve talking to 20+ people in the same chatroom?

Yes, if the unit is fixed (not on a swivel mount), the blades will reverse. I know msn doesn't involve 20 people, it just involves somebody else typing faster than me. Think of me as a stammerer chatting with a caffeine addict. It just isn't a comfortable thing to do.

>Yes, if the unit is fixed (not on a swivel mount), the blades will reverse. .oh... Well I did just hook the led from this car up to my first wind generator that I made with coffee tin cut-outs, as I noticed there was a fair bit of wind out there, sure enough, it lights up fairly bright when it's spinning full speed. The coffee tin blades are not exactly efficient, but for the amount of day's it's been sitting out there not spinning, it's cool to see it work. I got a question now, if I wanted to store quick bursts of energy from one of these and then to the led, should I wire a capacitor in parallel to the led or in series?

That is rather useful looking, I will save it on my computer for when the good weather comes about, I want to make a full size unit.

replace the battery and use it as a car?

I would, as the label clearly shows what kind I need to replace it with, but I don't think I have the remote for it anymore, or I would be hard pressed to find it.
