Hi, I'm doing a college course in Electronics and have a project to design and build an infra red switch for mains voltage. At college we use Electronics Workbench to help design and test out circuits but I can't get a copy for home use. I see there are, what sound like, similar programs on the downloads pages here. Has anyone any recommendations from these? I will only be using it for simple analogue circuits and it's really to test out ideas at home before committing to building them at college. Thanks, John
