Engineering on Friday ‘toon: The Meowplifier v1.0

The article discusses a project called the Meowplifier v1.0, a visual representation of a cat sound amplification collar. The project was born out of the idea to amplify a cat's meows to be super loud. The creator, an engineer, faced "project paralysis" due to too many ideas and limited resources. The cartoon was hand-drawn, taking about 4 hours without the use of AI. The creator experimented with coloring techniques and expressed a desire to see the project come to life through a crowdfunding approach.
