    I've had a Radio Shack 22-812 digital multimeter (about $70) for 7 or 8 years. It sat out in a cart in my shop for when I worked on cars, so I pretty much forgot about it (I always have my Fluke 83 close at hand). But it has a serial port and today I sat down and figured out how to talk to it with some help from the web.

    If you want to do some simple data logging, it could be a solution, especially if you don't already have a digital multimeter.

    I posted a python script at http://code.google.com/p/rs22812/ that will do the work for you.

    Once you've installed python and PySerial, go to a command line and type python rs22812.py and you'll start logging to stdout.

    That is a reasonably nice meter for the price (about $70). Given that it's autoranging, it can make a very slick data logging setup.

    Just when I had written the Shack off as really worthless.

    Based upon comments here, I checked out the RS site and read the posted reviews. Good information. I don't think I'll be looking to buy one.
