We have been meeting every Monday and Wednesday for the last 2 weeks. Our to-do list for the last 4 meetings has been working on the tubing, finalizing the circuit and 3D printing a holder for the atomizers.

We have updated our tubing design, instead of having a full ring around the hat we will now have a U shape with the ends of the tube being connected to the atomizer. This will be done because we decided to have 2 atomizers instead of 4. By having a U shape the distribution of the water will become even. Also having a U shape is easier to create because we will not need to cut and glue the tube which can increase the risk of leaks.

With the circuit, we have decided to go with a 555 chip instead of Arduino, this was done for many reasons. Using a 555 chip allows for a simpler, smaller and lighter circuit.

We are in the process of 3D printing holders for the circuit and for the atomizer. The holder for the atomizer will be designed to connect the tube straight to the atomizer while also preventing leaks. The circuit holder will allow for added protection for the circuit.

Our plan for Wednesday is to attach everything to the hat, creating the final product and then start performing different tests to ensure our product is safe, comfortable and meets all the requirements. Once our final product is complete we will meet with our advisor and sponsor to have them test the product and give us feedback. We will then work to improve our product based on this feedback to create the final product.
