Rebuilding the Odroid XU4 server

Rebuilding the Odroid XU4 server thumbnail
In a previous article I showcased a simple home server built around an Odroid XU4, which I dismantled soon after migrating to a full-size desktop computer. However, having the Odroid laying around unused was a bit of a waste and I recently started needing a secondary file server to store data backups. So I decided to build a new server with the single board computer

With the COVID-19 and the introduction of remote work, a many Japanese companies were struggling with the approval of documents, since those needed to be physically stamped with one's personal seal named Hanko. I decided to solve this issue by creating a web application to keep track of approvals

Rebuilding the GUI of this CMS with Nuxt.js

Rebuilding the GUI of this CMS with Nuxt.js thumbnail
I have been using this CMS for several years now and overall, it has served me well. However, as the GUI of the CMS was built as an single page application (SPA), meta tags and other SEO options could not easily be generated for each article.</p><p>To solve this problem, I rebuilt this GUI using Nuxt.js as as to leverage server-side rendering (SSR). Articles are now fetched from the CMS API server-side, which allows meta tags to be set before sending content to clients.

Weight tracker

Managing one's body weight can be quite a challenge. And as the quote from Peter Drucker goes, "You can't manage what you can't measure". So, I built a body weight scale that can upload data to an API of my choice, which was the object of this article.

File POSTer

Many web applications rely on the upload of files from client to server via a POST request. The content-type of this request is generally multipart/form-data. When developing the server-side of such application, being able to quickly test the upload feature can greatly increase productivity. So, I designed this simple web application that can POST a file to any URL.

Food manager

The other day, I found myself putting on some weight. This rather surprised me as I thought I was having a healthy diet and exercised almost daily. To identify the root of the problem, I decided to start measuring my calorie intake as well as the macronutrients that constitute said intake.

MQTT control dashboard

With the cloud native multi-user MQTT platform deployed, I started designing IoT devices that I could distribute to end users. However, without a GUI, interacting with those devices would be difficult. Of course, one could install applications like MQTT dash or similar but this would require tedious configuration such as MQTT broker and topics. I wanted to give users a simpler UX so I made this simple control interface that automatically displays a users devices and allows those to be controlled.

API tester

There are multiple tools available for API testing, Postman and Insomnia being probably the most popular. However, those are desktop applications that need to be installed. I wanted a solution that I can use in the browser so I made a simple web application to achieve basic API testing functions.
