Flashing Light Prize 2017 - Electromechanical Schmitt Trigger

Here is my entry for the flashing light contest 2017.
I have based my design on exploiting the lower operating voltage characteristics of a typical relay and have developed a sort of Electromechanical schmitt trigger, which I have then turned into an oscillator.
I explain what if found during testing of the relay and how I implemented my findings into my entry design.
Many thanks for watching and fingers crossed!
