[sdiy] Logic Analyzer Advice

[charlie]

Intronix Logic Port was the first pc based one i i bought, it is a real
work horse. It is still very capable given its age, just needs that one
type of usb cable you never have lying around if you forget it.

you can self build one too, we made these as part of a soldering class a
while ago , it's basically the same as the cheapest ones on amazon , it was
designed to fit inside a plastic egg for some reason i forget
