Georgia Tech’s Mason Bretan has built a robot that can not only play music, but is now learning how to compose its own tunes. Shimon is a four-armed, marimba-playing droid that draws upon its vast library of songs to help it write the music that it plays. The system was fed around 5,000 songs from composers such as Beethoven and Stefani Germanotta all the way through to acts like Miles Davis and The Beatles.
 How to Fast-Charge Your SupercapacitorSponsored by Maxim Integrated Supercapacitors (or ultracapacitors) are suited for short charge and discharge cycles. They require high currents for fast charge as well as a high voltage with a high number in series as shown in two usage cases: an automatic pallet shuttle and a fail-safe backup system. In these and many other cases, the fast charge is provided by a flexible, high-efficiency, high-voltage, and high-current charger based on a synchronous, step-down, supercapacitor charger controller. |
