Drawing schematics on a computer?

[pwdrive]

If I remember correctly the inksape files are SVG, I converted them to PNG to post them on this forum, can't remember whether or not if I did that conversion from within the inkscape program or whether I used a separate online converter, whichever ways it couldn't have been too complicated 'cos I'm a software dummy and managed to do it ok.

Good luck.
