I recently lost access to my old Wiring Diagram program ( Visio). I have upgraded to Chromebooks exclusively, so I had to find something new.
I found this program online- https://easyeda.com/
. It is a free, cloud based / Web based diagramming program. I've been using it now for about a year, and have found it reasonably useful. About as easy as the old Visio program was. Takes a little practice, but well worth it if you want to track your special projects and wiring. Your files are stored on the cloud, but you can download picture files for posting, and can also print in B/W or in Color.
