Phase I

Learning process, getting to know electronics and basic concepts about electric circuits
the logic, and how to draw them.


     
     
Bread boards, resistors, capacitors, relays, switches, 555 Timer ..etc


Phase II

Designing an experiment, using the concepts of either:
  • Variable resistance
  • Trigger Switch


     
When using liquid -water- as a conductor, and having poles connected to the circuit fixed in the
liquid pool, the change of the liquid level results in change of resistance.
     
Switching from the a motor mechanical way of changing the water level, to a more natural way.
using the force of air blowing, breathing, to change the water levels as shown in the sketch.
and thus changing the resistance!
     




Phase III

Developing the initial experiment. In this case, new features were added to the home made instrument.
Three extra "keys" -switches- were added to the design.Wiered to three extra 555 timers,
the keys decide which timers are connected and which are not.Resulting in a change in the output sound.


     
     
     



the exhibition :

Electric Trumpet

Exhibited in the summery works of the Bauhaus2014.
