Things you can do with diodes

You can simulate a bunch of these (and edit too) in your browser in CircuitLab:

Diode half-wave rectifier https://www.circuitlab.com/editor/4da864/

Diode full-wave (bridge) rectifier https://www.circuitlab.com/editor/f6ex5x/

Diode turn-off time https://www.circuitlab.com/editor/fwr26m/

LED with resistor biasing https://www.circuitlab.com/editor/z79rqm/

Zener diode voltage reference https://www.circuitlab.com/editor/7f3ndq/

Charge Pump Voltage Doubler https://www.circuitlab.com/editor/24t6h3ypc4e5/

Diode Cascade Voltage Multiplier https://www.circuitlab.com/editor/mh9d8k/

(note: I wrote the simulation engine)

Looks great! Would you have a recommendation for intro materials to help me learn the basics of electronics using CircuitLab? I have a working understanding of signal processing but building an actual circuit without electrocuting myself, not setting my Raspberry Pi on fire, or selecting the right set of components for the simplest DIY project based on spec sheets are a mystery to me.
