Hardware

Description

Here at hardware we designed the material parts for our project to succeed. We have been designing a bioassay that incubates the bacteria and allows detection of cadmium in the fishmeal products that have been diluted into the bacterial liquid. The bioassay is handheld and designed for maximum mobility and efficiency. In short, a small cadmium biosensor that any fisherman can use to test the quality of his fish. We also created an instruction set in order to allow the workers to be able to use the system safety with an understanding that they are working with bacteria and how to follow the proper disposal methods after using the bacteria.

Bioassay

The motor is used to shake the upper part of the bioassay in order to make sure the bacteria is able to obtain enough oxygen to work properly, the battery is just supplying power to the motor and heater which is connected to an arduino chip that has an lm35 temperature addition in order to monitor the temperature and keep the heater from heating the inside up past 37º C. The tubes merely contain the bacteria in medium with the fish added inside as soon as it’s ready to be tested. The Bleach waste buckets are in order to ensure there is minimal biohazard risk. It provides an area for the bacteria to be temporarily disposed of until the bioassay is off the fishing boat and the bleach containers are able to be dumped out. There will be multiple sets of 5 tubes in order to allow multiple tests throughout the fishing trip in order to ensure as reliable results as possible.


The motor shakes a part of the container, which is heated to 37 degrees. This ensures a quick, optimal breeding environment for the bacteria to detect cadmium.

Instructions

WARNING: YOU ARE WORKING WITH A BIOHAZARD!

  1. After use of the bacterial liquid, pour all the contents of the tubes into the bleach waste bucket and let them sit for a minimum of 5 minutes.
  2. Rinse the tubes with bleach and let them sit for 5 minutes before rinsing them off with water.
  3. Do not reuse tubes with bacterial liquid until the tubes are autoclaved.
  4. Dispose of bleach liquid after trip, the liquid should be disposed down a sink or other disposal system.
  5. Place any used tubes in a safe area on the boat where they will not move or be disturbed.

ADVERTENCIA: USTED ESTÁ TRABAJANDO CON UN PELIGRO BIOLÓGICO

  1. Después de trabajar con el líquido bacterial, vierta todo el contenido de los tubos en el contenedor de basura 1 y déjelos enjuagar por al menos 5 minutos.
  2. Enjuague los tubos con lejía y déjelos ahí por 5 minutos antes de enjuagarlos con agua.
  3. No reuse los tubos que hayan contenido líquido bacterial hasta que esterilice con autoclave.
  4. Deshágase de la lejía contaminada en un lavadero con bastante agua u otro sistema de limpieza.
  5. Ponga los tubos usados en un área segura en el barco en la que no se muevan o sean perturbados de alguna manera.
