I played around with building an Arduino Nano version of a Signal Generator. The project is on the brown prototyping board. It uses an AD9833 board (upper right on proto) and a 1.3 inch OLED display (lower left on proto). Two momentary switch buttons are connected to digital inputs on the Nano. You can also see that the oscilloscope is reading quite close to the programmed sine wave frequency.

I read about the project in an instructables.com posting by Peter Balch. Please note: What is shown above is wired to different digital inputs and was easily changed in the 'ino' file provided on Peter's page. (https://www.instructables.com/Signal-Generator-AD9833/).

An Inline RF Step Attenuator for QRPp Work
I don’t need to explain the attraction of low power operation; if you’re reading this, the chances are that you are already a convert. I’ve been operating with low power ever since first being licensed in the UK in the late 70’s as G8RYQ, and then G4IFA. One of my first rigs was a homebrew […]
The GM3OXX “Oxo” Transmitter
As well as the small stash of finished projects that grace my living space, I also have two small boxes containing various boards. Some of them are boards from part-finished projects that didn’t work. For whatever reason, I ran out of steam and, instead of troubleshooting them, put them carefully into a small box along […]
Ugly Construction!
Here’s a little project I put together on a whim about 18 months ago. It was my tribute to the unlicensed (i.e. pirate) beacon cluster around 4096 KHz. There were several of them operating in full force, with powers ranging from around 100mW to a watt or so a few years ago. Their heyday was […]
