So, I’ve started on my next book project, Ham Radio for Hackers. It’s going to be a collection of projects based on the Arduino and Raspberry Pi, with a bunch of other “makerish” stuff thrown in.
One of the first projects, if not the first, is going to be an Arduino/AD9850 DDS VFO. I’m using AD7C’s version as the starting point for mine.
One of the issues one always has with writing a book is generating illustrations, such as schematics and assembly drawings. One of the great tools out there that helps immensely with this is Fritzing. I’ve written about Fritzing before, but never had the opportunity to really use it.
Now, I do. Below, see my first real Fritzing drawing. You can click on the image to get a larger, easier-to-read version of the diagram.
And here’s the breadboard:

hi,
just came across your post scouring the web for the AD9850 part in Fritzing. You’ve apparently used it in your VFO, so i wonder if you could make that part file available somehow? It’s all but disappeared it seems…
Some assistance would be greatly appreciated!
