Ideas for stuff I can power with my stepper............other than leds...........or incandesent bulbs.
btw- 4 volts is the maximum.
thanks.

How about 2 small 1.5V electric motors

dunno- heard somewhere they draw alot of current

The problem with the stepper is that it can supply a limited amount of current. With a light load, it generated 17V, but it seems that it can only supply less than 100 milliamps without causing the voltage to drop to less than 5V. Things like motors tend to use a lot more than 100mA.
Part of the problem with the MP3 player is that it won't work without the battery inserted, but with the battery inserted, it wants to charge the battery. Charging the battery draws a lot more than 100mA.
The DC motor I salvaged from an old VCR should be able to drive a much heavier load, but I won't be able to get back to Clinton with it for at least another week.
What we really need are some way out crazy suggestions for things to power with either the stepper or the VCR motor.

Mr. O demonstrated that a small transistor radio worked well off a stepper.
I have also seen a Game Boy powered off one. I personally power a DC motor taken from a Meccano black plastic housing...it works beautifully off the stepper mounted in my Jensen 51 replica.
Proven to date:
- LED's
- incandescent bulb
- radio
- Game Boy
- small DC motor
I bet the small motor/water pump sold by KidWind would likewise work with a stepper to pump water to a fountain.
So...there's a few Clinton!

Gameboy colours and advance's only take 2 AA battery's, 1.5V each!

IT might be the MP3 player chosen is too big of one I suppose. My Stepper does about 6 volts under load and as high as 28 volts without a load or just an LED. Problem is, it takes a lot of power to run the stepper.

I used to have a GB Advance- but traded up to a Nintendo DS- that uses 5.2v.

Yes John, you're correct, because the MP3 player is trying to charge the battery as well as run the MP3 player, it's drawing too much current. That pulls the output voltage of the stepper below 5 Volts, which is the voltage required by the MP3 player.
This particular stepper doesn't seem to need very much power, but the down side is that the voltage drops quickly when you draw much current.
The important thing to remember with any kind of generator is total power available. Power is determined by multiplying Voltage (Volts) by Current (Amps). For instance, if a generator can generate 10 Volts at 1 Amp, the total power is 10 Watts. If the maximum current is 100 milliamps (0.1 Amp), the total power is only 1 Watt.

How about getting it to run a pager motor with a small fan glued to it.
Broken pagers can usually be picked up at the markets for a couple of dollars and I know their current draw are very low.

Good suggestion Tony. Those motors draw very little current.

Those old fashioned things people had before mobile phones that you rang a number and gave an operator a message and then the pager beeped and vibrated and got a short text message.
Usually telling you to ring someone.
You see them being used in old hospital shows when the doctors pager / beeper would go off to tell them they were needed.

My mom who works at a world class hospital around here as a registered nurse still uses beepers, they are quite more sophisticated though. Full color screen, 256mb memory, voice, video, and long text messages.
