Build a simple adjustable voltage regulator circuit with an LM317 and about four external components. The LM317 will deliver up to a 1.5 amp. For anything more than that, you'll need to use the LM138 which will deliver a maximum of 5 amps but it will need a heat sink. :)
Do a Google search for "LM 317 Calculator". Buy parts, build, enjoy your voltage. :D
Cool project. One suggestiong, put the capacitor across the bridge/load. It'll smooth out that DC waveform. You might have a little ripple but overall a much cleaner DC signal.
Two Qs: How did you connect the four windings to the bridge? In parallel? Also, do you think it would be possible to use a small transformer to get the voltage down (current up) so a few high power leds could be used and a large cap could be charged up? Been wanting to do the bike light.
The magnet is divided by thin layers of laminate to keep it from heating up as a result of Eddy Currents. Nothing to do with poles or anything, just to keep it from overheating.
@koulea You CAN generate power with a regular electric motor, just not as efficiently. The stepper has many more poles. Thanks to something called induction, poles passing by each other produce electrical pulses. This is why it outputs AC current
Cool! Thanks

Nice channel, just subed!
It would have been nice to seen how much Amp the DC motor used with/with out a load...
Keep up the good work!

All of the steppers I found are rated at 42vdc. What is the best way to get them to 12vdc once I use a bridge rectifier?

@HackaweekTV thanks I will look into it. Turns out my 24v stepper isn't a stepper at all, but this info is still relevant.

how did you connect 4 coils from the stepper in only one rectifier bridge?

You should experiment with the transformer. Yes I think it was in parallel. :)

This is really inspiring. I'm going to try making a push-pedal camping lamp using these ideas!

Very neat, as usual :) By the way, what's that IC on the bac of the pig?
I guess I'm gonna have to disassemble a couple of printers....

@GiorgioCapocasa Not sure what IC that is but it's just glued there for fun. :)

Can you also generate power with a normal motor? Why does it have to be a Stepper Motor ?

How many amps on the DC stepper?

@Comutix Watch 9:10 ... it's in milliamps. 1000 mA - 1 amp.
