The objective of this project is to design a suction machine that can be manufactured from locally available materials with the ability to run off batteries, electrical power (when available) or human power. This device should provide the broadest range of possible applications while still remaining under the $100 price limit.
The Final Prototype
Improvements to last semester’s design (including suction control, improved valves, a rigid member connecting the motor and diaphragm, and an overall size reduction) have been developed and tested. A working prototype has been built.
