Dan (YO3GGX) - Simple projects you can build or use at home


Here you will find some pieces of software and hardware built at home during my very limited free time. New projects will be added as time goes by.
The newly posted or updated ones are first in the list, in each category, to easily find new things when you come back.
If you like my little projects and you would like to contribute with a small amount you can do it through PayPal using the icon below.

A local forum is available here for technical discussions about my projects.
