Ideas

Install switches in bathrooms that when pressed would raise an alarm throughout the house. This is to indicate that someone needs help in one of the bathrooms. This becomes especially useful at nighttime because then people are in their own rooms and if someone hasn't got their phone in the bathroom when they fall, it would be extremely unlikely that it is noticed.

These would ideally operate on more efficient hardware than an RPi because that would make deploying them and powering them with AA cells a much more achievable and long-lasting task.

The video player used for YT Shorts doesn't have most of the playback controls like seek, volume, mute etc. But those videos can be played in the regular YT player by just replacing the url path.

Shorts player URL scheme: https://youtube.com/shorts/<video-id> Regular player URL scheme: https://youtube.com/watch?v=<video-id>

Note (2023-03-23): This won't work anymore as now when YT detects the video-id to belong to a Shorts video, it redirects the regular player to the Shorts player.

Note: Eventually I made it and now it is live on the interwebs (the server is on a free tier so give it a few mins to load).

Google Contacts does have the birthdays of many people in your circles, but it doesn't expose those birthdays as a calendar feed which can be consumed from other calendar applications. So this will connect with Google Contacts and expose an iCal feed that you can subscribe to from any calendar application of your choice.

Based off of Trust Invitation I want to build a physical manifestation of it. One possible shape it could take is a LCD screen and a button attached to an Arduino which will show one random prompt on the screen each time the button is pressed.

The idea is to have a servo-motor driven compass which points us to the destination that we have selected in the companion app. It doesn't point us to which route we should take but just generally which direction our destination is in. First version can be just an Android app showing a compass needle pointing towards our destination.

Many websites (such as banking) don't allow you to copy-paste your passwords. It would be awesome to have a keyboard which can send out HID signals for your password so that it appears as if you are typing the password instead of copy-pasting. Perfect bypass for every such shitty detection algorithms.

We can hook up a typical morse-code key to a microcontroller like an ESP32 and then connect that to a computer. We can connect to the computer as an HID and then send keystrokes to the computer based on the morse code entered.

Recently I have seen a lot of online booksellers here offer something along the lines of a "Random Book Box" in which they would select x number of random books from their inventory and package it for you.

Those are the parts I like about the idea but what I don't like is that generally these are sellers of used books and their inventory consists mostly of titles that I've never heard before and that I won't actually care about reading.

My idea is basically to build something to which I can tell about what books I want to read and what books some of my friends suggest, then it can build me a box out of those which then a friend can order for me. Similarly, I can be one of the friends who makes such a random book box for one of my friends.
