Enthusiasts Joe and Brad designed a clever, electronically controlled, two-stage model rocket powered by a 9V NiCad battery. The heart of the electronic control system consists of a small FPGA with a soft-core processor that runs the control algorithm and logic. It uses a PWM signal from an accelerometer to determine the rocket's acceleration to trigger the ignition of the rocket motor in the second stage, separation of the booster from the sustainer, and the deployment of a parachute that allows the rocket to float gently back to earth.
1: 518-2233 is a 2×36 header. Cut it down to create the 2×8 and 2×5 headers.
2: 518-2225 is a 1×36 header. Cut it down to create the 1×3 header.
Additional parts required for main board: Altera EP1C3 cyclone FPGA; Altera EPCS1 configuration flash; 40 MHz Osc, Epson SG8002CA; Max 604, linear regulator. (Note that several of these components could be replaced with components offered by Allied with minimal redesign or verification.) See website for daughter board parts list.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
With LEDs dropping in price virtually every year, automakers have begun employing them, not only on luxury vehicles, but on entry-level models, as well.

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
