Do you love technology and problem-solving? Join our STEM Inventor Club and enjoy amazing benefits. Inventor club is not just about coding or electronics. We also help you re-invent common products or tools using cost-effective methods. Even if you don’t want to earn profits, you can still save money on reusing common household items versus buying brand new. It is also a great way to bond with family and friends or help the community.

You can join our club as an in-person or an online member.
