What is a remix? When you remix a project on Makerpad, you’re submitting a project that relates to an existing project. You're trying to use the same Tools, copy and edit the functionality in new ways and/or show off what you can do with a similar system. So for example, the community submits a number of projects that are examples of doing specific things without code that you can remix to get started with your own projects.
Currently there's no functionality for cloning the existing projects.
