In summary, the person is seeking help in building a device to move a wooden rod back and forth like a musical metronome. They have a budget of $50 and need it to reach 200 rpms. Another person suggests using a small electric motor with a reduction gear and a single linkage attached above the pivot point, which can be found at a hobby shop.

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.

Sure, I'd be happy to help you build something like that! Here are a few ideas for how you could approach this project:

1. Use a motor: You could attach a small motor to the base of your contraption and attach the wood rod to the motor's rotating shaft. This would allow you to control the speed and direction of the rod's movement. Motors can be found for under $50 and can achieve 200 rpm easily. However, you may need to add some gears or pulleys to adjust the speed of the rod as needed.

2. Use a pendulum: Another option is to use a pendulum mechanism to create the back and forth movement. This could be done by attaching the rod to a pivot point and using a weight at the bottom of the rod to create the swinging motion. The speed of the pendulum can be adjusted by changing the length of the rod or the weight of the weight. This method may be more cost-effective, but may require some trial and error to find the right balance for the desired speed.

3. Use a simple lever: If you're looking for a more low-tech solution, you could use a simple lever and fulcrum system to create the back and forth movement. This could be achieved by attaching the rod to one end of the lever and using a weight or counterbalance on the other end. The speed and distance of the back and forth movement can be adjusted by changing the length of the lever and the weight of the counterbalance.

No matter which approach you choose, be sure to carefully plan and test your design before building it to ensure it meets your needs. Good luck with your project!
 

Related to Help building something that will go back and forth

1. How can I build a simple back and forth motion using basic materials?

One way to create a back and forth motion is by using a lever and fulcrum system. This can be done by attaching a long stick or rod to a pivot point, or fulcrum. By applying force to one end of the lever, the other end will move back and forth.

2. What types of mechanisms can be used to achieve a back and forth motion?

Aside from the lever and fulcrum system, other common mechanisms for creating back and forth motion include pulleys, gears, and cams. These mechanisms can be used alone or in combination with each other to achieve different types of back and forth motion.

3. Are there any important safety considerations when building something that goes back and forth?

Yes, it is important to consider the speed and force of the back and forth motion and to ensure that any moving parts are properly secured and do not pose a risk to the user. It is also important to use appropriate materials and to follow any safety guidelines or instructions provided with the materials or tools being used.

4. Can a back and forth motion be controlled or adjusted?

Yes, depending on the mechanism used, a back and forth motion can be controlled or adjusted by changing the length of the lever arm, adjusting the position of the fulcrum, or changing the size or shape of the gears or cams being used. This allows for different types of back and forth motion to be achieved.

5. What types of projects or applications can benefit from a back and forth motion?

A back and forth motion can be useful in a variety of projects and applications. For example, it can be used in simple machines, such as a seesaw or wheelbarrow, or in more complex systems, such as a conveyor belt or robotic arm. It can also be used in scientific experiments or demonstrations, such as pendulums or oscillating motion.
