8 channel logic Analyzer for 5 bucks

[Larz60+]

What can you do concretely with this?

it could be used on code where you want to syncronize timer and a/d converter in a circuit. This would require only 2 channels, but modern logic analyzers in general are sold in increments of 8 channels start at hundreds of dollars. I expect that this will change soon.

In the past (1980's), I used them quite often, for example to syncronize stepper motor movement (when motor ramping was done by software) to show time between steps. Or to trace interrupt timing on several inputs, happening at close intervals, to see the order and timing of the interrupts.

Here's an example (even though code is not python) that would use all 8 channels:
