Sadly, Dr. E’s WeDo Challenges and Dr. E’s MINDSTORMS Challenges will no longer be posting new challenges. However, both websites will remain up so that you can continue to access the previous challenges and all of the wonderful submissions. Thank you to LEGO Education and to the Center for Engineering Education and Outreach at Tufts University for their years of support (and thank you to LEGO for their amazing robotics platforms). During the six years of WeDo challlenges and five years of MINDSTORMS challenges, we received almost 1000 submissions from around the world. The two websites had a total of 1266 registered users from 57 different countries. We were truly a global community! We have always been inspired and energized by the creativity and innovation shown by the Dr. E's Challenges community; while new challenges won't be posted moving forward, we hope that you continue doing awesome stuff in your homes, clubs, and classrooms and that you continue to share your projects with the world! Collaborating with all of you has been a joy and an inspiration. Thank you, The folks at Dr. E’s



 I got my idea for building a drum because my grandfather used to play the drum for us at night. Also, my brother has a bongo set.  We made our mallet heavy so it could make loud noises like a drum.  Someties the mallet was a lttle too heavy and fell off.

    I love that you have used crafting materials. Maybe try making a small hole in the drum to give it more sound – if you study a drumset you will see that the drums have a small hole on the side. Try playing around with a drum to see what happens 🙂 I like that you found a very complex way to control the drumstick – which is extremely cool by the way. Very good job 🙂
