>> The question was about "home-brew" things. Visio is hardly "home brew" ! (I find this comes up a lot. For one reason or another, you want to develop a "cheap" something-or-other, and it turns out that what is "cheap" can be highly "localized." You can develop a PCB layout methodology for Visio, but it's really only useful if you HAVE visio (a $400+ software package.) On the other hand, add-ons to Eagle are useful to anyone with windows or linux... BillW -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
