Summary:
My first look at the digital world.
-OVERVIEW-




4 bit Computer
             4/1/2003              Complete              A basic 7400 series 4-bit arithmetic computer.


       This circuit was actually for a class project. It took meticulous planning, design, and construction. It is actually classified as a simple computer because it can preform arithmetic operations on a user inputted number based on another user inputted command. This computer can add, increment, decrement, compliment, logically shift left, and several other things. After all the designing and with a well documented self-made schematic right infront of me, it still took about 5 hours just to build. The wireing schematic I designed in LogicWorks.



      


Multi-Tone Generator
             2/1/2003              Complete              Quick project that emits multiple tones.


       This was probably one of the most annoying projects I have ever made. This circuit simply emmits a loud oscillating ear piercing tone. The drive circuit is controlled by a 555 timer chip and the frequency can be regulated by changing just one resister value.
