I built myself a proud parent machine

Summary by Krater

Simone Giertz builds an automated 'Proud Parent' machine that accepts a quarter, lights up, and plays an audio file saying 'Proud of you, son' while a mechanical hand pats a shoulder. She tests the prototype, constructs the wooden box and suit design, and installs an Arduino microcontroller, servo motor, and coin acceptor, successfully reaching a break-even point with her coin-operated affirmation.

Answers: How do you build a coin-operated proud parent machine?

• building an automated affirmation machine
• woodworking and laser cutting plywood
• integrating Arduino microcontroller with servo motor
• coin acceptor mechanism installation
• mechanical hand design and mounting

What it concludes

• The Proud Parent machine is already at break-even point with one coin going in and one coin coming out.
• Adam Savage confirms the machine is gruesome and agrees to provide the voice for it.
