Hi All,

This may be interesting to some, IIRC someone in one of the threads was looking for a data logger, now if it could be reworked to data log the dc from solar/wind, it might be a good help.

must have to join up.
didn't see a schematic

Hi Randall,


There's a link that you have to download.

This little unit looks like a nice start to building an even more powerful data logger. It's even got a small breadboard on board.

thats a pretty cool micro setup, and it looks like you get a lot for the 130bucks, which is very competitive
for the market they are targeting.

awe but yet another processor and likely another language to learn

Bob,

Hava look at this link is to a Self-Powered Solar Data Logger http://www.circuitcellar.com/library/print/0107/Krich198/index.htm it looks like a simple way to make a charge controller, even for a diesel bat charger.

An example of using the micro comp. in creating a voltage controlled transformer.

It may have been my reply to the multi-purpose digital USB scope module.

I have to tell you guys about a really slick software package made by Jim Sky of www.radiosky.com . His software runs on a PC and controls either a 2-channel sound card to use as the data input device, OR better, an 12 bit A/D converter that has 8 analog channels accepting 0-+5 VDC input.  I bought the pro version and also the 8-bit converter box for use in my own radio observatory but have not had the opportunity to use it very much.  It takes this data and gathers it in a format that can be monitored remotely via the internet, stored locally, shared with others etc.  It looks like a chart recorder.  Time stamps can be in standard time or sidereal time (the system was originally designed for astronomical data gathering).  In the astronomy application there is a chat channel so that other observatories also tied in to the same linkup will have a communications channel like a telco 'order-wire' common between repeater sites.

There is no reason this couldn't be used to monitor AC mains voltage, the height of your pond, windspeed, anything you can make a transducer and DC interface for.

Best of all the price is very good and a free version to run with the sound card is available.  Two and a half thumbs up!
