A common alternative was the logic probe. At the low end, this could be an inverter and an LED, although it was more common to have a little extra circuitry to actually do a comparison to a ...

Or something. In any case, it’s more just a case of ingenuity as this guy needed a very sharp little probe to test some voltages out of a few very tiny pins. So he rigged up a medical-grade ...

These signals are then easily probed using a standard logic analyzer probe. The second group of signals consists of the “forgotten signals.” These are signals that weren't brought out to a ...

Trying to probe a modern electronic circuit with tiny SMD components, without letting the magic smoke escape in the process, can be quite a challenge. Especially since we hackers have not yet ...
