Each entry below is one lab open ended question, solved once on a machine with the real simulators and reviewed by a human before it was published. The circuit file, every measured number with its provenance, and the explanation are all here.
This site cannot simulate. LTspice is a Windows GUI application; it does not run on a server, and substituting a simulator that could would answer a slightly different question with different device models. So the generator runs locally and the site is only a window onto what it produced. Every number here is traceable to a real simulator run.
A question that is not listed is not solved yet. That is a real answer rather than a failure state. There is deliberately no path here that looks like an instant answer but is secretly unverified generation.
