Re: what can the cable company detect?
Install them how? A typical opto will require at least several millamps of current to make the input side of it do anything useful -- that's DC. A typical cable is carrying a bunch of different RF

Re: Flyback transformer test
Alien Steve The flyback has a ferrite core going down the middle of the windings and extending outside to form a large 0. This large 0 is made with a split which is held together by a large U shaped

Re: what can the cable company detect?
Dear Group: This may be a stupid suggestion, but what if one were to install optoisloators on the cable line? This would short-circuit (literally and figuratively)what the cable company can detect? Or

Capacitor
Hi all, I've got this capacitor with a rating of 5200uf and 64WV. What does WV means? wave volts? But how does this converts to Volts. Thanks, Davin

somebody with experience with video signals can probably answer, as I have NO knowledge in this area........but I think that the signal coming over your cable line is not simply two discrete voltage

Re: Flyback transformer test
I have seen several circuits as you have described. I plan to try and open up the plastic flyback housing and see if it is possible to add some primary windings easily. The horz circuit from the

I cut the vinyl on my sign cutter. Despite having no holes, it does not use SMT parts. Instead it uses standard DIP ICs and through hole parts, but with the leads trimmed almost flush and surface

Re: Unknown Transformer
If you know what the primary side is (the one for the 120ac) you just can hook it up and measure the secondary. But it is safer to test with low voltage. Normally one uses another transformer or a

Re: what can the cable company detect?
Phone companies use a technique called "Time Domain Reflectometry (TDR)" which is a type of radar. It can be used on any type of cable and optical fibre. Its very accurate, down to a centimetre or so.
