SUMMARY

The discussion focuses on building a device that moves a wooden rod back and forth, similar to a musical metronome, with a target speed of 200 RPM and a budget of $50. Key components include a small electric motor, potentially with a reduction gear, and a linkage system attached above the pivot point. Participants suggest sourcing materials from a hobby shop to achieve the desired functionality efficiently.

PREREQUISITES
  • Understanding of basic mechanical linkage systems
  • Knowledge of electric motor specifications and selection
  • Familiarity with reduction gears and their applications
  • Basic skills in assembling mechanical components
NEXT STEPS
  • Research small electric motors suitable for 200 RPM applications
  • Explore different types of reduction gears and their configurations
  • Learn about mechanical linkage design for oscillating motion
  • Investigate budget-friendly sourcing options at local hobby shops
USEFUL FOR

This discussion is beneficial for hobbyists, DIY enthusiasts, and engineers interested in mechanical design and automation projects, particularly those focused on creating oscillating mechanisms.

Hey
I was wondering if you all could help me. I need to build something that will move a rod of wood back and forth in a fashion similar to a musical metronome.

I am hopeing to make it for under 50 dollars and need it to go about 200 rpms at min.

all you need is a small electric motor, perhaps with a reduction gear, and a single linkage attached above the pivot point. Try a hobby shop.
