I'm trying to support my family by making the stuff I like. The economic situation in my country is currently not good and many of my friends left. Since I don't want to leave, I have to take additional jobs in order to keep my beloved alive and healthy. That is why some of projects placed on my homepage are not free and marked this way:

Design for Money (dfm)

NOTE: The projects marked as DFM will be fully published except firmware files (HEX) files containing controllers software. Pre-programmed chips can be ordered instead HEX files, also kits or ready-made units.

There are also a number of projects marked this way:

Design for Free (dff)

These are fully published, including all needed HEX files. If you have made your units using some of these projects, I'd appreciate your feedback including some photos/drawings of what you've done. I'd like to publish these photos but won't do it without your explicit agreement. Receiving more such pictures can motivate me to put on site more of this kind of designs.
