GMU:Devices of Perception/Khaldoun Alhanawi

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!
