Ya, it looks much better in real, even it looks good on my camera but it seems that youtube is dropping frames... <br>In the vid, the bottom half is obscured by the fan...<br><br>I've got it mounted and it's now displaying temperature and humidity... <br>When it gets a bit darker tonight I'll take some pics on long shutter and get some vid.. .<br><br>I'm thinking about building a bigger one, with a rechargeable battery to keep it running when it's not windy... <br>Prolly with an RTC for time, maybe some other sensors... <br><br>Michael <br><br><hr id="stopSpelling">Date: Tue, 27 Jul 2010 14:25:27 -0400<br>Subject: Re: [Lab] windPOV project<br>From: aomalley@gmail.com<br>To: krazatchu@hotmail.com<br>CC: lab@artengine.ca<br><br>Looking good!

Hey...<br><br>I've just uploaded a video to youtube of the WindPOV ... <br>I haven't got the sensor code running yet but everything else is working... <br>It seems that the SHT21 follows the actual I2C spec as opposed to the older SHT11 which is somewhat proprietary in it's interface.<br>
There is an Arduino library for the SHT21 which should be easy to port... However, it's a bit slow to test as I have not included serial or LCD on this board... <br><br>You can see the video at youtube<a href="http://www.youtube.com/watch?v=CJ89A6P1ULQ" target="_blank"> http://www.youtube.com/watch?v=CJ89A6P1ULQ</a><br>

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 href="http://krazatchu.ca/?page_id=198%20" target="_blank"><span></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>
