The OhmNest learning bench
Build it. Measure it.
Understand it.
Step-by-step guides with expected results and practical troubleshooting. Read here or follow along inside the workbench.
Build your first circuit
Draw a voltage divider from a blank sheet, wire its terminals and measure 2.5 V.
Simulation · 8 minUse the scope and function generator
Compare two signals, change a source and read time-domain measurements.
Simulation · 5 minRun a circuit live
Keep a circuit running while you adjust the generator and component values.
Simulation · 7 minRead Bode plots and spectra
Measure filter gain and phase, then inspect the frequencies in a captured signal.
Simulation · 6 minCapture digital timing
Read a clocked flip-flop and confirm that its output divides the clock frequency by two.
Verification · 10 minVerify a design across tolerances
Run every resistor/capacitor corner, inspect failures and preserve the evidence.
Verification · 8 minMeasure noise across temperature
Distinguish spectral density from integrated RMS noise and compare temperature cases.
PCB design · 15 minRoute and export a two-layer PCB
Inspect pad mappings, repair a route and generate checked manufacturing files.
Electrical documentation · 12 minCreate electrical documentation
Work with sheets, shared device functions, cross-references and a linked PDF book.
Electrical documentation · 8 minDocument PLC IO, terminals and cables
Trace a three-wire sensor through a terminal to a PLC and generate its schedules.
Getting started · 6 minSave, share and recover projects
Keep editable designs, understand local recovery and preserve simulation evidence.
