It has been a long time since my last blog post (WeakSignalTransmitter - part 2 - filter design ) but the Si5351 is still not available and I had other things to do. But I managed to get a breakout board for the Si5351 and attached it to my filt...

To get a fully (mostly) analog signal out of the Si5351 the signal needs to be filtered. regulatory limits and calculations I plan to use my transmitter mostly in the 50 MHz, 70 MHz and 144 MHz ham radio bands.Radio regulations say (at leas...
www.youtube.com/watch In this video, I demonstrate how the visualized ADC (vADC) works. For the final version of the project, I put all of the analog electronics onto perma-protoboards. I really like working with these because they make converti...
I have now written the code to produce pulses to implement the pulse generator mode of the Micro Servo Tester, see the listing below. I have only included the pulse generatong function as that is the only part that has changed. void pulseg...
Hello Everyone, My name is Harji Nagi. I am currently a third-year student studying electronics and communication engineering from Pranveer Singh Institute Of Technology (PSIT), Kanpur(Uttar Pradesh).I have a keen interest in robotics, Arduino, Artif...
Inside of every successive-approximation-register-analog-to-digital converter (SAR ADC) is a digital-to-analog converter (DAC!) This DAC generates an analog voltage that gets compared to the input signal. By changing the DAC, it is possible to find...
The initial idea was to make a robot named “DrawBo” which can draw and teach drawing. But now this idea has been broadened to drawing on the glass, or on the fabrics .Apart from this, the robot can make a sketches and drawing of anything and everythi...

Short update. During my live stream today, we played with a small TFT LCD module. I shot this short video after the stream. It demonstrates the ADC digitizing an input voltage of 4.23 volts. Notice the 4-...
INTRODUCTION this project is based on the principle of electromagnetic introduction, this phenomenon was discovered by an English scientist Michael Faraday in 1831 , according to this principle if a conductor is placed in a varia...
I have made some progress with my combined servo tester and pulse generator project. I am happy with the servo tester part so I have decided to add an OLED display (128 x 64) and a button to select different modes. The Servo Tester will be the first...
A SAR ADC generates voltages through a DAC and then compares that analog voltage to the input voltage. This search takes some amount of time. If the input voltage changes while the search happens, then the search would fall apart. A "sample a...
Introduction I have a module on an ADS1256 chip. I bought this module for experimenting with homemade geophones. But since spare parts for geophones will be arriving for a long time, I decided to experiment with this mod...

One of the key reasons I wanted to build a SAR ADC is its heart is a digital-to-analog converter (DAC). So it is a two-for-one project. As a quick summary, a SAR ADC uses a DAC to generate analog voltage...
For the Data Conversion Project14 challenge I decided that I wanted to use a multi-turn potentiometer so I have started to make a micro servo motor tester. I have wanted a servo motor tester for some time but didn't want to spend any money, pl...
This is project AquaLoop, design of 4-20mA current loop based water level indicator for all sized water tanks. The main target is to make the system robust, low noise, less lossy over a distance for signal transmission. I am using a BC547 based wate...
I finally am well enough to get down to my workshop, so I figured I had better try to get a project done before I get incapacitated again.
Project Description
This project is an exploration of implementing an analog to digital converter witho...
Topic: Keep an analog signal digital as long as possible - including the power amplifier - and by doing that, avoid all that efficiency losses (and heat generation) of analog amplifiers.
When you think about a DAC, you often imagine a mechan...

Any physical quantity in our world has to be converted to a voltage to be measured in electronics. Even if you have a sensor that outputs a digital bus like SPI or I2C, inside of that sensor is an ADC. There are many types, with Flash, SAR, and Sig...
