I came across the rain drop sensor module and was interested in its application area. Like I wondered if this rain drop sensor can be use to harness power like using solar. But I came to know that this cannot be achieved. The reason being simply that it is just a rain detector or conducti…

I had first heard and read about the current controlled voltage source(ICVS) amplifier back in the engineering class but I had never chance to dwell deeper into this and other types of negative feedback circuits , what and where they can be applied.…
Here I wanted to record the effect of bypass capacitor used to bypass the flow of signal across the emitter resistor of an amplifier. Below is an example circuit. This is multistage amplifier with two stages of common emitter BJT based amplifier wi…
I was reading about negative feedback circuit specifically amplifier circuits with negative feedback, how these circuit works and how I can use the concept as well as the circuit. Negative feedback improves gain stability, improves input and output…
I had salvaged a neon bulb from a soldering iron and wanted to use it in some circuit. I remembered that a bulb is used in Wien bridge oscillator when i wrote about building the wien bridge oscillator calculator and wondered whether the neon bulb o…
I came across an amplifier circuit diagram of multistage amplifier built with BJT transistors. The circuit illustrated negative feedback amplifier design. I always wanted to learn transistors based circuit with negative and positive feedback. Negati…
Today I decided to test the AD7840 14 bit DAC that I had bought long time ago for telephone project. I wanted to learn, utilize it and perhaps incoporate to build independent communication system with Arduino AM transmitter and Arduino AM receiver…
I haven't used the Arduino Due lately, so I wanted to use it in the AD7849 DAC project which I wanted to use to generate carrier signal for AM transmitter based on Arduino Due and AD7840. But when I typed the board name it was not found. After …
I always forget the distance between two pins of Arduino header pins, prefboard etc which is actually a standard value. For record the spacing is 0.1 inch which is 2. 44 mm. Here’s a breakdown for each: 1. Arduino Headers : Pin spacing : 2.54 m…
