Low Cost Mini Projects for Mechanical Engineering Students

Being an engineering student, you know the importance of building good mini projects. As the scope of the mini project that you build extends beyond your engineering curriculum and helps greatly in improving your confidence while attending interviews or applying for higher studies admissions.

But the main constrain for most of the engineering students is the cost that they have to incur in doing such innovative mini projects.

Doing good mini project with reduced cost is not easy, as it requires a lot of components and resources to complete it effectively.

So, what you can do to reduce the cost other than compromising the mini project itself?

For this, I am suggesting some tips which will help you reduce the cost of your mini project without compromising the quality of it.

  1. Build project as a team: In addition to the conventional benefits that you gain by building your mini project as a team, you will also get the flexibility to share the project cost between all. In this way, everyone will have to spend relatively a lesser cost to build an innovative mini project in comparison with doing them individually.
  2. Seek expert guidance: Don’t just rely on your project guide to get all the guidance. You need to seek the guidance of experts who have a good knowledge on your project domain. This will help you avoid unnecessary expenditure on your projects.
  3. Utilize the resources at your disposal: Before you begin your project, identify all the resources (materials & facilities) available for you to utilize without any cost at your college and other places. This will help you to make an effective project plan with the least external expenditure.
  4. Don’t damage the kits: A number of students who do mechatronics and robotics projects (because mechanical students are not generally very experienced with electronics) end up damaging the circuits which are very costly. So try to work with companies like Skyfi Labs who give you excellent video tutorials and explanation that will help you avoid wrong connections and burning of your circuits. It will be really sad if your project stops working due to a short circuit or burnt IC one day before your presentation as all your effort and cost goes waste. So we strongly suggest to utilize our project based courses to avoid such mishaps!
  5. Buy kits with competitive prices: Most of the components that you need to build your mini project will not come with a fixed price tag like smart phones. So be careful who you trust. Look at reviews and ask your friends about the companies before you buy from them.
  6. Project without any plan is expensive: Doing mini projects without any plan will just make your project cost to reach new peaks. So before you start with your mini project execution, discuss well with your team members and mentors to draft an efficient project plan. This will help you allocate budgets for specific activities and you will not end up with empty wallet at the mid of project.

Although these suggestions are applicable for all the mini projects, if you are looking to build mechanical engineering mini projects you need to take the above tips more seriously. As doing good mechanical mini projects at low cost is extremely difficult and proper care should be taken during the execution to save money wherever possible.
