The addition of a 10-to-1 probe circuit greatly extends measurement capability of the device. You can attach user-defined expansion modules to the channel interface for a variety of applications.

It’s a pretty clever system with very simple and flexible circuitry. [0033mer] says he’s used this over twisted-pair wires a couple of hundred feet long, which is pretty impressive.

Saleae logic analyzers seem to have it all: good sampling rates, convenient protocol decoding, and plenty of channels – but not a good way to set rising or falling-edge triggering. [James] found ...

A simple electric circuit learns to classify data in a creative new design that could lead to more energy-efficient machine-learning hardware.
