Quick References

As a constant learner, I get to touch upon many ideas in different areas. This category is for me to capture those ideas which I felt people may reference to get ahead of their tasks. Most of the time, I do come back to this section of my blog to remember what I had learnt in the past.

How I created my own USB powered LED nightlight

If you wish to avoid tripping in a very dark room while not affecting sleep quality, then you can use a nightlight to succinctly lit up a portion of your room.

While there are many nightlight variations out there, it can be a meaningful exercise to try to create your own out of items that you already own or have in the house.

For example, instead of throwing away the Carrot Carotene Calming Water Pad container after the water pads ran out, I used it to create my nightlight.

Since it is translucent, this container can help dim the lights coming from the naked 5V Warm white LED light strip.

Given that, let us take a look at how I made use of the items that I already have to create a USB powered LED nightlight.

With some level of variations, you should be able to make your own USB powered LED nightlight too.

How to add an inline cord switch onto the cable of a USB powered device

Some time ago, I shared a post of how to make your own USB powered LED light. If you follow that post, you will be able to make your own USB powered LED light that can be attached to a USB 2.0 power adapter on your wall socket. When you turn on your wall socket, the lights will turn on. After you are done with using your light, you can turn off your wall socket to turn off the lights.

Sounds like common sense right?

However, your wall socket plug may be too far to reach at your convenience. In such a situation, you may want to add a switch onto the cable of your USB powered device.

Given that, this post discusses how we can add a switch to a 5V USB wire. In this post, I will use a white inline cord switch as an example to show how we can add an inline cord switch to a 5V USB wire.

Rendering multiple checkboxes with WTForms and Bootstrap

When you use WTForms and Bootstrap, you can quickly build up the dashboard for your own content management system with Python.

This is because WTForms provide several out-of-the-box implementations for rendering some basic fields that for capturing form data.

However, rendering multiple checkboxes can be open to different UI implementations based on users’ preferences. Therefore, different fields and widgets are available in WTForms to cater for different ways of displaying a form input to the user.

Given these points, let’s see how we can render multiple checkboxes with WTForms and Bootstrap.

How I repaired one of my corrupted git repository on gogs git server

While trying to commit my codes to my Raspberry Pi gogs git server, I got a rejection:

 ! [remote rejected] master -> master (missing necessary objects)
error: failed to push some refs to ''

In addition to that, I got a HTTP 500 when I try to view the repository details page via the dashboard.

Since I can view my other repositories on my gogs git server, something must be wrong with a-project.git.

Given that, here are the steps that I took to rectify the issue.

Installing Netflix app on a Chinese made projector device running Android

An easy way to install Raspberry Pi OS – using Raspberry Pi Imager

Once got an microSD card for your Raspberry Pi in your mailbox, you can install an operating system to run it.

Typically, we download a Raspberry Pi image and use one of the imaging software to write it to our microSD card.

When the Raspberry Pi Imager came into the picture, the download step is consolidated into a single workflow.

Given that, this is how you can use the Raspberry Pi Imager to install Raspberry Pi OS.
