Initial Phase of handle
Something simple would do –> using a levered switch and pressing on it like a gun, connect the 2 parts with a screw.
Prototype of the handle
This is what we have so far and it works! The switch fits snugly inside the hole at the side meant for the switch.
Final Product
Below shows the final handle design! It looks very different from the prototype. A series of buttons and a LED display as explained in the development process page was added to make the handle more user friendly.
Initial Phase of nozzles
The basic design features a blow hole for the compressed air to flow. 2 other nozzles has also been created, one has 2 blow holes to ensure that a larger surface area can be covered when cleaning areas such as grills (as in the desktop/laptop component). Another design features edges that are perpendicular to corners so it enables ease of cleaning at the corners of walls or cupboards that are usually very hard to vacuum.

Final Product
We decided on these 3 eventual designs to be used in our physical experiments to determine the effectiveness of our device. The air-tube pipe has been re-designed and standardized across all nozzles to allow for the air tube to be placed in the same location on the handle regardless of the nozzle.
