I don't see the "hard part" as being how to collect the readings... but "what to read"... Many of the wood moisture meters use probes that you drive into the wood to that you measure resistance between two probes, a known distance apart. Measuring resistance in wood chips, which might vary from packed sawdust to plane shavings (long curls of pretty solid wood, which would pack very poorly.) would probably vary too much to be useful. If you have something uniform like, say pellets for a wood stove, things might be a bit more predictable. If you could extract a sample and weigh it both wet and "after drying" you might get a useful reading.. but.. that's if you believe that all you drove off by drying was the water... (a short stint downwind of a wood drying kiln will convince you that there are lots of other volatile chemicals like terpenes, driven off from drying wood.) Once you've got the readings, how to process them may be the easy part. Steve ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
