William's Workbench

I ran across this schematic for a simple 1-wire serial adapter.

25-pin	9-pin

Update

I built one of these adapters and am using it to monitor 3 DS18S20 temperature sensors in my home using cacti.

There are a lot of these out there but in true DIY spirit I wrote my own. You may need to download the .NET runtime libraries to run it.
