I was just sent this from a Solaris server (in case that matters):



Your "cron" job on lab

rm /home/jacoby/Test/*.Rout &> /dev/null



produced the following output:



/home/jacoby/Test/*.Rout: No such file or directory

OK, I need a 556 timer ( ~$2 at Radio Shack ), 2 x linear pots ( ~$3 each ). What more do I need to get to make one of these? He doesn't include a parts list and I don't really read schematics yet.
