Need to try and measure cable delay(propagation) #2

Need to try and measure cable delay(propagation) as seen in this post on BlurBusters.

I have no idea how he:

  1. Measured the cable lag at all (but I found this paper for measuring coax and skimmed through it.
  2. How he was previously measuring times as slow as 4 ms?? I don't actually think it's possible for a signal to transmit that slowly unless you're sending it through mercury or something?

I think this guy may have been conflating "cable lag" with the actual speed of the device... not sure though.

Also just found this comment as well: image

Looks like this site was all set to kind of give this thing away, but it was never released.

Also, this guy makes me feel like I have no fucking idea what I'm doing: image

Holy shit. This was 8 years ago? Does he work for NVidia now or what?

No idea, but they never followed through and posted the instructions or the source code, and they never released a commercial piece of hardware... So we'll still be first to market.
