Our first device. The black pipe is taped onto the exhaust port to force air out of the bag (see two pictures down).
This device was structurally unstable as we were still learning about 3D design and the 3D printer. The top
cover didnt fully screw on and the mid section could slide around. Furthermore, the internal screw holes were
easily worn down. These problems were all fixed in our second prototype.
This was the pipe connecting the vaccum pipe to the well established dust sensor. The readings from this sensor are to
be used to calibrate our device.
The full setup. We were forced to place our device into a bag to give the fan the ability to pull air from the vaccum
pipe. At the top of the picture you can see how the pipe was sealed inside the bag to prevent air leakage. This was a
temporary solution. We will later design an attachment to the deivce that will allow for a proper pipe connection.
Our assembly was connected to the vaccum pipe via the tubes taped to the wall.
Featuring NASA equipment.
The entire assembly. A huge thanks to Dr. Tom for allowing us to squat in his testing area.
