Hi Guys,I am using old monitor (SONY b/w moniter) to do patch clamp on slices. But the monitor can not record the whole process for patching.Now I want to film my process for patching as a demonstration. I know I need a PCI card with BNC inlet, and I also need the software to record it.Do you have any recommendations? I know there are some commerical ones available, but it is kinda expensive. I want to bulild up a home made one. Could you please tell me how to do that? thanks a lot.
