Ultimate 555 timer Design

Create an innovative 555 design, the 555 should be the heart of the circuit. Here are some pages having 555 design ideas that will help you learn quickly. Learn and Do-it-Yourself or DIY. Better still CIY – Create it Yourself. Be Creative, Be original and Shake the Planet.

Signetics made the 555, This is one IC that is like a E-LEGO, this along with Op-Amps and other components can make many interesting projects. On some pins like Control Voltage it responds to analog signals and on Reset and Output the signals are Digital like. The 7555 a CMOS version consumes lower power and oscillates at higher frequencies. This evergreen or perennial chip is the favorite among students and hobbyists who want to learn electronics. Here is an original datasheet from Signetics i found online, it has very nice illustrations which will act as an appetizer for learning this science.

The Incredible 555 : Here are some 555 circuits, The most versatile and simple chip of all time ! Some of my 555 Circuits are at my blog – 555-Circuits – delabs Schematics The best part of the 555 is that it has an voltage detection. It has a Versatile Logic which is defined by voltage comparators. The ability to loop it like an opamp for feedback makes it the first “Programmable” Mixed Chip. In short it make an ideal building block.

Learning Electronics – 01

Theory must be studied once and referred again and again as you do practicals. One is by building DIY projects and then modifying them. Also Repair of equipment, troubleshooting, testing and calibrating. Then you know how components behave and real life limitations. Now design and engineer a product and test it at customer site. do a pilot production and test with more clients. Now you will learn to think based on practical application.

This invention lead to modern electronics, computers and internet look at this page, Transistor Photo.

History of The Transistor the “Crystal Triode”

A picture of the first transistor ever assembled, invented in Bell Labs in 1947. It was called a point contact transistor because amplification or transistor action occurred when two pointed metal contacts were pressed onto the surface of the semiconductor material.
