Electronics Projects

The following are a few of the projects that I involve myself in:

Microcontroller programming
Moving LED sign

Cool HTML-based clock
Switching 110VAC on and off (relays vs. solid state)
110VAC computer controlled dimmer
Using an 8255 PPI chip
Sound system information

Here are other projects that I'm wanting to get to one of these days...

• Animatronics (computer controlled puppetry) using stepper motors

The following are a couple of excellent reference sites:

Chip Directory
Extensive list of mail order places to purchase electronic parts from

NOTES:  Remember that power (in watts) is equal to the voltage times the current.  However, this is only true when the load is resistive (such as light bulbs) and has no capacitive or no inductive component (such as motors and so on). If you have the value any two of these variables, one can easily figure out the value of the third. The formula would look like this:

W (watts) = V (voltage) x A (current in amps)

Here's another good formula to have and remember:

Voltage = Current* Resistance
