Week 9

Week 9: July 27 to July 31

It was decided to use the beeps. Using the speaker although it might give more information it is harder and a little unnecessary for this project. I bought a 5v active buzzer for beeps since I found that to be the most useful option. The other issue that the device presented to be useful was mobility. This was solved with the hat with 2 18650 batteries. Giving energy for a little over one hour they were very good, their only issue is the weight. Something to be fixed in future versions, however this module is the only one I found in short noticed to be bought. The volume of the beep is very loud as well, so I got a 10k potentiometer to control the current and therefore the volume. This proved to be very efficient. Concluding that the device is ready, I ran more testing on it using the beep, the computer now is only being used to start the code. After more measures with the tape I found the distances of the beep to be similar to the one’s provided by the camera, only with an estimated 2 to 3 seconds delay to start beeping. This is not very significant for the project in mind. With that concluded I intend to start writing the final paper next week. s
