Motivational Box

Do you ever find yourself struggling to stay motivated and on track with your daily tasks? Maybe you start off strong, but as the day goes on, you find yourself getting distracted or losing focus. If so, you're not alone. In this project tutorial, I'm going to show you a fun and effective way to stay motivated and achieve your goals. It's called the Motivational Box, and the goal of it is simple. I have a few tasks I want to complete, the RED LED indicated an uncompleted task, once I completed the task I will press the arcade button it will turn the LED to the corresponding arcade button (or any color of your choosing) and update it on a site where I can track the days I completed my tasks. The graph is inspired by GitHub code contribution heatmap.

Now for you to understand why I created this project I need to tell you a story. The last few months, I was really struggling with my motivation. I had a lot of goals that I wanted to achieve, but I just couldn't seem to get started. I tried all kinds of things - setting reminders on my phone, using sticky notes, even trying to hire a personal coach or telling all my friends and colleagues today is the day I am going to change. But nothing really worked.

Disclaimer - JLCPCB graciously sponsored this project by providing the PCB utilized in its development.

Component

1 - Raspberry Pi Pico W

1 - Custom PCB (JLCPCB)

5 - Arcade buttons (30mm)

3D printed parts - (Files below)

Miscellaneous (glue etc.)

Wires

Tools

Soldering Iron + Solder

Computer + Thonny IDE

Screw driver

Hotglue gun

The schematic diagram is shown below. The design is straightforward as each button was connected to a GPIO pin to the Raspberry Pi Pico W, and a connector for the neopixel RGB LEDs.

The PCB was ordered through JLCPCB. They offer great PCBs at a low cost and have promotions and coupons available throughout the year. You can sign up using here, or using the following link:

before creating the token from github let's first look at the website and hosting

You can download the tracker website files here: https://github.com/Guitarman9119/motivational_box/tree/main

The easiest method will be to clone the repository and make the neccecary changes so it corresponds to the tasks you have made for yourself.

Edit the index.html and change the heading to each corresponding task you have chosen for yourself:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Task Heatmaps</title>
  <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/meyer-reset/2.0/reset.min.css">
  <link rel="stylesheet" href="styles.css">
</head>
<body>


  <h1>Blender</h1>     
  <div class="graph-container">
  <div class="graph">
    <ul class="months">

here we can change the h1 to be any other task.

Do this for all the tasks or skills you want to track daily.

Netlify was used to host the tracker as it offers free hosting for small projects. Sign up to netlify and add a new site. You can deploy with GitHub. This will guide you through the steps to allow netlify to access and read your repository to host your tracker online.

Log in to Your GitHub Account: Make sure you're logged in to your GitHub account.

Access Personal Access Tokens Settings:

• Click on your profile picture in the upper-right corner.
• Choose "Settings" from the dropdown menu.
• In the left sidebar, select "Developer settings", then click on "Personal access tokens".

Generate a New Token:

• Click on the "Fine-grained tokens" button.
• Click on generate new token
• You might be prompted to enter your GitHub password to proceed.

Configure Token Settings:

• Enter a meaningful name for your token to help you remember its purpose.
• Choose the desired expiration for the token. You can choose between no expiration, a set expiration, or a custom expiration.

Select Scopes:

1. GitHub provides a range of scopes that determine the level of access your token will have. You can grant access to specific repositories, organizations, and services. Be cautious and only select the scopes that are necessary for your intended use.
2. Repository access: Select the repository where you will have your website.
3. Generate Token: Once you've selected the appropriate scopes, click the "Generate token" button at the bottom of the page.
4. Copy and Store the Token: After generating the token, GitHub will display the token value on the screen. This is the only time you'll see the token, so be sure to copy it and store it securely. Treat this token like a password, as it grants access to your account.
5. Use the Token: You can now use the generated token in your applications, scripts, or any other place where you need to authenticate with GitHub. When making API requests, include the token in the headers (Authorization header) as a bearer token. Use this token in code above.

Remember to keep your tokens secure and never share them publicly. If you believe a token has been compromised, you can regenerate or delete it from the GitHub settings.

The box was designed in Fustion 360. It is important that you use white filament for task indicator to allow the LED to diffuse through the white filament to indicate the task status.

You can download all the 3D files here: https://github.com/Guitarman9119/Raspberry-Pi-Pico-/tree/main/Motivational%20Box/3D%20STL%20Files

It was a fun project to create and I do believe that using this box will keep me motivated. If you have any questions you can comment down below, or follow me on YouTube and comment on the video if you need any help creating your own motivational box.
