Week 12 Onshape Tryout


In my learning plan, I did mention I want to learn OnShape software. And I did it. As a beginner in the software, I search for some online tutorials to try to familiarize myself with how to use it. I also asked my friends who are experts in this software to teach me about some basic tools for using it. Onshape Modeling
Here are some of my outcomes while learning OnShape software


 The inner part of the device - uses for holding the buttons
The center attach part of the device - uses for holding the soldered Arduino board and its component. The button cover- attach the button component and this cover will be displayed outside.
The holes around the 4 corners - hold the screws
The holes on the top of the device - microphone


Testing the User-friendliness of the product While doing this, I also did some quick user testing on the user-friendliness of this product. I gave them the scenario and ask them what would they do on the occasion. User 1

User 2

From the quick user testing, I ask them about their preferable microphone placement, and both of them gave the same answer which is the top part of the device same as what I expected. The reason they prefer the top part is that they get to easier accessing the microphone, the gesture of one hand holding the device proves that the top part is the most suitable way to record audio.

Get the wrong width of the button cover, it's too thick

Intentionally did this to get the correct size of the button cover

Week 13 Soldering the Arduino component To actually scale down the size of the Arduino, I need to solder them to make them smaller and fit into the device. As a beginner, I tried to search online about soldering to make sure that I'm going on the right path. I do try out different ways of soldering them to make sure they are not affected.

First method - directly solder component to the board

The second method - is not solder components to the board
 I then ended up wasting the components that had soldered to the board because I change the method of soldering to make sure the component can be easily removed without soldering it. which is using this female pin header that can attach the Arduino component and I just solder the pin. In case, I want to change the placement of the Arduino circuit, I can easily remove them by detaching them. But the downside of doing this is it will need more space for the whole Arduino circuit thing.


Confirmed amplifier attached to the circuit

By doing this, destroy an unwanted speaker given by the lecturer, and take out its amplifier inside, it works well in this case.

Final Submission - Week 18

   Week 18 Final Submission This week, I refined my rationale video and arrange the files folders that need to be submitted. Presentation slide Here is the Google link Project Background Normal people take notes on their phone or digital notepad to remember things. Similarly, blind people use audio recording to keep track of tasks and plans. They carry essential items every day, which use up their memory. Problem statement However, phone recording is inconvenient for them as it may record voice instructions and the files are disorganized without labels. They have to go through more steps to find the recording they want. Device Overview   Function Record & Playback Main features  3 main Braille buttons Item Task Phone number Target Audience Blind workers Place Wearable device Rationale Our brains have a limited capacity for memory storage, so taking notes is a common way to remember important information. Similarly, blind people also rely on note-taking to keep track of thei

Hand Up Do good Project Proposal - Week 7

Image
  Project Category I choose the sixth category for the assignments which is optimizing: making daily activities more efficient. Project Background Our human brains can store a maximum amount of memory. Therefore, we rely on taking notes down in case we forgot. This task seems so simple for normal people to do, we normally send messages in our own chat on our phone or take notes in a digital notepad. Similarly, most blind people have the habit of taking notes too. They use audio recording as a result to keep track of these tasks and plans. However, they experience inconvenience from the phone recording because they will record the voice instructions if they use their phone at the same time. In addition, the audio files are arranged in an absolute mess without labels. Besides, there are more steps for them to click the recording they want. Because they need to go to work every day, they always bring their essentials —white canes, work bags, wallets, and keys— along with them. None o
