I'm starting a new photo series on this blog, and the content won't be found anywhere else. :)
My husband's made a wide variety of his own test equipment and such over the years. We've finally decided to document them, and he's given me permission to post them on my blog. :)
This is one of my favorites: The Portable VCO
This is a battery operated, CEM-based VCO that could very easily fit in a pocket.
The VCO uses a 9 volt battery to power a circuit that uses a CEM3340.
It is very stable and tracks extremely well.
It features both 1/8" and 1/4" jacks for CV in and Audio out.
