It's funny that you mention that! I just got my hands on several
steppers and the first thing I did was make a rectifier and power some
LEDs. Just a tip. you can cut the number of diodes you use in half by
pairing pins 1&3 and 2&4 on the same bridge because they are
both the same polarity at the same time I believe... One more
question... is that a hall effect sensor on there?<br>

Hey peoples... <br>
<br>
For the last day and half I've been working on a wind turbine powered
weather station using an 8 bit/LED POV on the spinning blades for the
display...<br>
I'm trying to one up the neighbors solar LEDs.. lol<br>
<br>
The stepper being used as a generator is mounted to the blades and the
shaft is held stationary to negate the need for slip rings... <br>
I have the hardware built and am currently working on the code. The
entire system is running under 5 volts (3.5v) which is a first for me...<br>
<br>
The project is semi-written up on my site here <a
moz-do-not-send="true" href="http://krazatchu.ca/?page_id=198%20"><span
id="PresenceContainer"></span>http://krazatchu.ca/?page_id=198 </a><br>
I will add the code and eagle files once it's finished... <br>
Let me know what you think...<br>
<br>
Michael<br>
