Getting Started with the EBAZ4205 as a Zynq-7000 Development Board

The EBAZ4205 is the least costly Zynq-7000 based board that I luckily happened to chance upon. However, it wasn’t my first Zynq-7000 board. That happened to be the MYIR’s (Make Your Ideas Real) Z-Turn board (with a Zynq-7010 SoC). I purchased this board for approximately Ksh. 12,000. It was to be my gateway into FPGAs, … Continue reading Getting Started with the EBAZ4205 as a Zynq-7000 Development Board

AC, DC Coupling on the Oscilloscope: When to Use Which

From my experience, if you were to step into a college electronics lab session and ask a student "When would you set an oscilloscope channel to either AC or DC coupling" chances are you'll get something along the line, "AC coupling is for AC signals and DC coupling is for DC signals". While there is … Continue reading AC, DC Coupling on the Oscilloscope: When to Use Which

A Practical Implementation of A Two Quadrant Transconductance Analogue Multiplier

One of the circuits that I've spent an inordinate amount of time investigating this year is the Analogue Multiplier. An analogue multiplier is a circuit block which takes two analogue signals and produces an output which is proportional to their product. Analogue multipliers can be integrated as part of a larger circuit blocks to perform … Continue reading A Practical Implementation of A Two Quadrant Transconductance Analogue Multiplier

A Curious Case of GNU(Radio Companion v3.7.13.5/v1.6)

On new year's day (2020), I decided to get reacquainted with GNURadio Companion (grc) to mess around with some Software Defined Radio (SDR) stuff, and set myself off on a new vector of exploration. But for the life of me, I couldn't get things to work right off the bat. The last time I had … Continue reading A Curious Case of GNU(Radio Companion v3.7.13.5/v1.6)

How to Get Your HS420361K-32 4 Digit 7 Segment Display Working with an Arduino

Typically when I get new electronic components to play with, I just google the part number and lookup tutorials on how to get it working. This has been a pretty successful strategy more often than not. However, this wasn't the case when I needed to get the HS420361K-32 4 digit 7 segment display to work. … Continue reading How to Get Your HS420361K-32 4 Digit 7 Segment Display Working with an Arduino
