cctalk Digest, Vol 26, Issue 29

[Anders Nelson]

Hey Rob (and anyone else sniffing signals),

I've been using a USB logic analyzer from Saleae (https://www.saleae.com/)
for years now and the software is really good. Way cheaper than a
standalone unit. I'm unsure if the inputs can handle more than 5v but you
could throw a divider network in front and try it.

Also there's the Digilent Analog Discovery (
https://www.sparkfun.com/products/13929) which does the same stuff but I
can't vouch for the software as I've never used it. Inputs can handle
+/-20v apparently.
