Discussion Overview

The discussion revolves around finding a suitable low RPM motor for a digital guitar tuner project. Participants explore options for motors that can provide precise control for tuning guitar strings, with specific requirements such as size, voltage, and reversibility.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant describes their project of creating a digital guitar tuner and requests recommendations for a tiny hobby motor with low RPM, ideally running on 5V and reversible.
  • Another participant suggests that a stepper motor would be suitable due to its controllability, but notes the potential complexity of the required interface and the challenge of finding one that operates at 5V with sufficient torque.
  • A third participant agrees that stepper motors are easy to control but acknowledges the complexity of the interface.
  • A later reply expresses gratitude for the information provided, indicating it aligns with their needs.

Areas of Agreement / Disagreement

Participants generally agree that a stepper motor could be a viable option for the project, but there are concerns about the complexity of control and the limitations regarding power and torque at 5V. The discussion remains unresolved regarding the best motor choice.

Contextual Notes

Limitations include the uncertainty about the availability of suitable motors that meet all specified requirements and the potential need for additional equipment to operate a stepper motor effectively.

Hello all. As a Digital project, I'm trying to construct a digital guitar tuner that will actually tune the guitar for you, all you have to do is put the device on the tuner and pluck a string. My problem is I'm not very mechanically inclined...

Does anyone know a tiny hobby motor with a very low RPM (it only takes the slightest touch usually to tune a guitar). It'd be nice if it ran off of 5V (so I can get the digital components and motor off the same supply), reversibile (for tuning up and down), and some kind of guide for motor basics?? If this exists can you point me in the right direction?

If ever there was an application for a stepper motor...The controlability is exactly what you are looking for. However, the drawback is the equipment required to operate one.

http://www.solarbotics.net/library/pdflib/pdf/motorbas.pdfYou definitely would want something low speed and high torque. I can't say that I have ever heard of one running off of 5V though. You wouldn't have much power available to turn a tuning peg that has a tensile load due to string tension. I think you may have to concede that design point.

stepper motor are easiest to control though the interface is a bit complex
 
Thanks, looks like exactly what I was looking for! Appreciate it!
