EE Labs

Four interactive labs cover circuits, signals, and control through 153 experiments. Plots and calculations stay consistent, and tests block faulty deployments. The code is MIT-licensed.

Open labSource
Signal Lab: high-pass a square A sampled 250 Hz square wave before and after a 700 Hz second-order high-pass filter. The lower plot uses a fixed linear 0 to 4000 Hz axis and a fixed minus 60 to plus 3 decibel range. The response is minus 3.01 decibels at cutoff. Harmonic levels are decibels relative to unit peak amplitude; normalized waveform amplitude uses a fixed minus 2.5 to plus 2.5 scale. Sample rate 8000 Hz; Q equals one over the square root of two.

RF Reference

Eight RF bench calculators run on phones and tablets. Calculations use your inputs, and the URL preserves your settings.

Field Catalog

Cull and catalog wildlife photos locally on Windows. Compare bursts, use optional local or API-based species identification, and maintain a life list and map. Rejected photos stay on disk until you choose to delete them.
