Digital Multimeter

Metering – Instrument Projects / By Ibrar Ayyub

The purpose of this project was to design a functioning digital meter to measure voltage, current, and resistance to a known accuracy. The project involved the integration of hardware and software to take an input measurement signal from a pair of high and low leads that was then displayed on an LCD per the rotary

Stable Orientation – Digital IMU 6DOF + Arduino

Metering – Instrument Projects / By Ibrar Ayyub

A while back we wrote an article on sensing orientation with the adxl335 accelerometer. In that article I mentioned all the drawbacks of trying to do this with just an accelerometer, and said that if you needed something stable, what you really needed was an IMU. Well… We are back with an article covering just

DIY Digital Compass (for your car)

Electronics News Updates / By Ibrar Ayyub

I’m astounded that some cars don’t have a digital compass always visible. You either have to launch the navigation app each time which may even disappear when you adjust the radio. In this project, you’ll create a digital compass that can be powered by by the cigarette lighter or another source (batteries make it handheld).

6 Digit LED Clock

Electronics News Updates / By Ibrar Ayyub

I recently found six 2.3″ red 7 segment displays in my collection which I purchased from Rapid Electronics when they were clearing out non-RoHS stock. Since I have no clock at my work bench I decided to construct one from some prototyping pad board, a Microchip PIC18F26K20 microcontroller and a Dallas DS32KHZ temperature compensated 32.768kHz

FM430 – A MSP430 and TEA5767 Project that lets you listen to clear digital FM

Electronics News Updates / By Ibrar Ayyub

One fine day while i was rummaging through the part bin, I found an old project that probably was never completed ! FM Radio ! I tried to make one when i was in 7th grade, waiting at the counter of a dingy electronics repair shop for anyone to pay attention to the parts list

World’s first fully digital radio transmitter built purely from microprocessor technology

Electronics News Updates / By Ibrar Ayyub

For the first time in history, a prototype radio has been created that is claimed to be completely digital, generating high-frequency radio waves purely through the use of integrated circuits and a set of patented algorithms without using conventional analog radio circuits in any way whatsoever. This breakthrough technology promises to vastly improve the wireless
