CD duplicators are a great way to make a small batch of CDs. Commercial units cost around $500, can be finicky, and usually come with some weird proprietary software. Maker Paul Rea wanted something a little less restrictive and cost conscious, so he built one out of LEGO and an Arduino. At least if it becomes temperamental, he’ll probably have a bucket of spare parts handy.

    I really like this. You combined lego with RC servo motors and an Ardunio to create an inexpensive functional CD duplicator.
    Great job.
