Flashing LEDs Electronic Kit– ApogeeKits created the Flashing LED’s electronic kit AMK102B as an entry level introduction to electronic kit building.

World of Heathkit do-it-yourself electronicsAll of man’s progress has stemmed from ideas, ideas held by men and women who pioneer new concepts.

LED Blitzer is a LED BlinkerThis strange circuit was in Openclipart i am not sure if it will work. Later i found (more…)

This is the third circuit that you will need to build a Simple Benchtop DMM with no Microcontroller. Here the U1D and (more…)

Input Impedance of this module is Ri as pin 2 is at virtual ground, the opamp with feedback tries to maintain pin (more…)

I read your post which is about, Digital gain control of Op-amp. I have some questions to ask, if possible. Please reply (more…)
