MY FIRST WORKING LIGHT BULB
This is the actual lamp making starting point, or the first success. Bulb is worked for only 20 min, but it was a clear sign and motivation to continue work! At that time I had no tools, pumping station, only a little bit of knowledge and strong will to make my dream come true.
