Here two 1.44 Mb floppy boxes were used up creatively, an unique Desktop Utility was created. 1.44 Mb seems to be supersede-ed by Pen Drives or Thumb Drives. This is as Green as you can get, no plastic waste. Something rare, one of a kind. You don’t get these kind of things in the stores. So DIY, Recycle.

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

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.

Interactive Tutorials using Virtual Electronic Components 

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.
