Digital Tutor Gadgets with Canvas View

The Digital Electronic Interactive Tutors Gadgets, have a canvas view now. That means in iGoogle and Google Sites, you can set it to full size with a embedded schematic. The Normal view is also available unchanged.
Here is a Snapshot of a Live iGoogle Page showing a Digital Preset counter Gadget in Canvas view.
Other Gadgets are Logic Gates Tutor and Digital Timer

Analog Op-Amp Tutors with Gadgets

I have made some Web Widgets, these are analog opamp tutors. Interactive Tutorial with Simulated Meters and Potentiometers, demonstrating how Operational Amplifier functions in different configurations.

Slide the Potentiometers just like you would operate a Sliding Control. Drag the Knob on Pot to increase or decrease the resistance. The Resistance is shown is blue letters and dynamically alters value as you slide the pot.

The mV Source is varied by just moving mouse pointer over the two buttons, no clicking. This reduces finger strain and also you have a long lasting mouse. The mV buttons are special, the variation picks up speed if you let the mouse pointer remain on the button. This is Ramp-up and Ramp-down. This enables you to set it faster with just two buttons.

Finally you have a DVM a Digital Volt Meter that just Displays the Voltage at any Point, this readout value has to be noted down.

I am also attempting a Toy Scope or a waveform display.
