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/).

  • Testing Out Different Headsets with a Crystal Set and Assembling a Sound-Powered Headset
    Before building Jim W4LF’s Hobbydyne™ crystal set, I put together an impedance matchbox, for matching the detector diode to a variety of different headsets and earphones, so that I could determine the best ones to use. The world of serious crystal set listening was new to me, so I did some reading up. To give […]
  • A Crystal Set Impedance Matchbox
    Growing up as the youngest of 4 boys, I was well positioned to receive all the hand-me-downs. Although that might sound as if I just ended up with second-rate stuff, that was not the case at all. I inherited a lot of great things from my older brothers. I couldn’t have cared less that they’d […]
  • 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 […]
