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/).

  • A Little WSPR Beacon (Aren’t They All Little?)
    I first tried WSPR out in 2009, with a Signalink USB interface attached to my FT-817 and PC. For anyone interested in QRP and QRPp, the process of being able to decode a signal that is up to about 34dB below the noise level is quite fascinating. Morse code, sent by way of CW, engages […]
  • Another HiFER Beacon
    I haven’t been building much at all, for quite a long time now. However, the urge occasionally returns. When it does, it’s wonderful to have a small stash of parts on hand, so I can pull the soldering iron out and start building before the desire dissipates. I’ve been interested in beacons for a while, […]
  • A Passive Tunable HF Preselector
    When I built the VE7BPO DC Receiver Mainframe recently, it wasn’t intended to end up as a final finished project. The intention was more to have it as part of an experimental platform. The little box that contains the DBM, diplexer, and AF amplifier that make up the mainframe will most likely stay largely the […]
