Virtual Oscilloscope - Visualize Equations

Oscilloscope Functions and Fourier Series. Periodic Waveforms. Watch Sine, Square, Triangle and Sawtooth Waves and Study Controls. This Scope is a Real Time Graph of Volts Y and Time X at any node of a circuit. It can show both AC and DC.

Load an equation of your own and see it as a waveform on this web scope. Paste a Formula in the Equation text box, load it, it will be rendered as waveform on scope. Learn from this page ....

Get The JS Oscilloscope Demo

Just turn it on and then press demo button for 1st Waveform and Press again the demo button for 2nd Wave and so on. Still working on formulas. Slide all the pots and see what happens.

Eco Green Digital Alarm Clock

This is an upgrade of the digital-alarm-clock gadget which used embed for sound. In this version it uses SoundManager 2. The older version remains intact.

You can set Five Alarms with Ten Selectable Musical Sounds and a small Text memo. Digital Alarm Clock Web Gadget with Musical Alarms.

This is an Alarm Clock Simulation, Eco Green is to inspire saving energy and keeping earth Green, Clean and last longer.

This is an experimental gadget, usable but not easy. This gadget can demonstrate how difficult ergonomics is, when you need to press buttons in sequence to get an electronic gadget to perform.

This problem in user interface for electronic gadgets was vanquished by Touchscreen Interface as seen in the now popular iPad and iPod.

I am still trying to fit the best functionality within the 210px-115px GUI real estate. Now with sound manager which uses flash, alarm sounds may be more consistent. Making various sound/video formats play on all browsers is a messy task. Flash makes it easy but you need a plugin.
