What could be cooler than launching model rockets? Launching a lot of them! To control multiple rocket launches relative to one another and put on an utterly amazing backyard air show, Joe designed a circuit (replicated for each rocket) consisting of two 555 timers configured for monostable operation and a high-current FET. A single launch button is wired parallel to all of the circuits. Delay times (from the activation of the launch button to the activation of the FET) are adjusted with a potentiometer and range from a small fraction of a second to tens of seconds.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
