This week we finished a few tasks such as finalizing the CAD design for our device and soldering everything to the Arduino Nano. The parts of our devices were soldered to save room on our device to cut down space taken up by bulky wires and pins. This also helps ensure that there is always a good connection between the components.
The design we decided to go with is a two piece body. One to go on the top of the wrist and one to go on the bottom. The top compartment will house the primary parts of the device such as the Arduino and the breadboards, and the bottom will hold the battery and sensors. To run the wires from the Arduino to the battery and sensors in the bottom the wires will run through the armband itself in between the layers.
Figure 1: This is the design for the top part of the device.
Built into the sides of the body pieces are slots to secure the armband on both sides as shown in Figure 1. Also shown in Figure 1 is the small slot to secure the screen on top of the body to easily display the data.
Figure 2: This is the design for the bottom part of the device.
For the bottom part we needed to have a separate compartment for the battery of this device. This is to ensure that if the battery does heat up it will not effect the Arduino at all. Below this compartment are two smaller ones to house the sensors of the device, and both of these compartments have holes at the bottom as shown in Figure 2 to allow the sensors to make contact with the wearer to get accurate readings.
