TI has released some FRAM based MSPs which are fast and could retain memory in the absence of power. I feel that they are suitable to improve this kind of applications. Are there any limitations to use them here ?

  Very excited to see this, As a fligth shooter I have a very specific interest in the velocity of the arrow throughout its flight. Is there anyway I can talk to you about this? Steve Gardner

I have made two arrow based systems. One was launched by a bow. It was a video camera and radio transmitter. The resulting video clearly shows the sky, the horizon, and then the rapidly approaching ground. Single stepping through shows blades of grass just before impact. The other system was a three-axis accelerometer designed to be lowered into very small diameter wells. I needed some high strength, small-diameter precision tubing. Being an archer, I realized than an arrow shaft would be cheap and perfect. Instead of paying $200 a foot for precision tubing, I could get a dozen arrow shafts for $50 (although our procurement department questioned what appeared to be non-work related items). Arrow shafts are 100,000 PSI tensile strength aluminum and are incredibly straight and uniform in wall thickness.

Can you do a case-study on either one of your designs? My site FAQ tells you what we are looking for: http://www.eetimes.com/ContentEETimes/Documents/Schweber/FAQSept2010.pdf or email me: bill.schweber@ubm.com
