Have you ever taken a look at mains transformers - they have hundreds if not thousands of turns. Also your laptop already has an isolated power supply so since it is safe to use the laptop without getting an electrical shock, it is also safe to connect your oscilloscope to the laptop directly. Isolating the laptop mains with an isolation transformer achieves nothing. Unless you are repairing the power supply itself. | |
| May 21 at 19:26 | comment | added | neural | Btw - edited my OP to make it clear I understand that the device under test is the one that needs isolating. Point is I need an isolation transformer. I'm not trying to make you look silly in your reply, sorry to retroactively edit like that, but I realize that my original wording was ambiguous | |
| May 21 at 19:18 | comment | added | neural | As far as calculations go, I think 1-1 is pretty straightforward, no? I'm going to calculate the amount I can wind with the length of wire I have and use all of it. I estimate I can get about 10-20 turns on each side, something like that. And as far as safety goes, I plan to put it through some tests and see how it performs. I don't need it to provide a lot of power, I'm not going to be using it for my refrigerator, but for small appliances like my laptop and any things I want to test with my scope | |
