Raspberry Pi project ideas: Nobody asked for these, Pi fans did it anyway

Nobody asked for these, but we Raspberry Pi fans just built it anyway.

Smile detector

Take this project from lee cyborg.

Lee built a smile detector which, as you can see from the video, activates an LED when they smile.

It’s pretty prototypey at its current stage, but it shows real promise.

Twitter user grime_ninja asked Lee why they decided to build this project. He asked,

“is this to prove to others that you do indeed smile, and make it clearer when it is happening? Or is this an alert to help reinforce yourself never smiling again?”

Lee replied,

“So people far and wide can come and observe the much requested smile. It’s a beacon. A beacon of how much I hate everyone.”

Ah.

There’s so much potential for this project. Imagine being able to play an applause sound every time you smiled. Or canned laughter every time you smile (which enhances the probability someone would laugh at your joke).

This isn’t Lee’s only face-based project, though. Here’s a scrunch detector and a chin switch.

Portable Python practice Cyberdeck

It takes 10,000 hours to master a skill.

Why not make a portable Python programming rig to ensure no lapses in your programming routine?

That’s exactly what Chris Remboldt did.

Chris built his rig out of these components:

In addition to being a mobile Python practice kit, Chris built this to program his Raspberry Pi Pico, which is easily programmed via Thonny, which is installed on the Raspberry Pi OS by default.

He cautions that you should be careful as this is quite fragile, “but a 3D printed case would solve that.”

Raspberry Pi Zero Jukebox

Scott Petersen modified his old jukebox and installed a Raspberry Pi.

He built it in about 3 months, starting with zero knowledge of the Raspberry Pi or Python.

There are actually two parts to his project. What you are seeing in this picture is a wall box/consolette which collects the money and also chooses songs for the jukebox to play.

Instead of a jukebox with music media in it, Scott used the Raspberry Pi Zero that interprets the signals from the consolette and plays the correct music.
