The Beatty family built a moving model of a Mars rover for the New York Hall of Science’s exhibit. They used a 12-channel Mini Maestro and step-down voltage regulators. Pictures and a link to a video are available on their blog.

In this video, Jay May explains how to use the Micro Maestro to control his Iron Man suit.

We expect to release a simple carrier for ST’s new LPS331AP pressure sensor this week. While testing and writing example programs for the sensor, one of our engineers, Kevin, came up with a nice demonstration that calculates and displays the altitude on our Orangutan SVP robot controller. It was a beautiful spring day with great flying weather, so Paul and I took Kevin’s digital altimeter on a flight to Lake Havasu City, Arizona, to see how it compared to the altimeter in a plane.
