Observation Project TWO, Phase II
Posted on October 16, 2005 at 02:02 AM by sj695
We convened and decided to each take a paddle and try out different sensors. We all ended up in the lab at the same time and worked from one board, each testing after another.
Conclusions and findings:
- Drum trigger is digital NOT analog. Had to be hit at a specific pt and not big enough to cover surface area of paddle.
- Flex sensor. Idea was to attach multiple flex sensors to a paddle. Only flex sensor detects when a tennis ball hits it but the range of values is small, very similiar to values when just moving paddle. We tried a various of resistors but this just dropped the values from 900 to 200, but the overall number range stayed the same. After three different flex sensors and no consistent results we decided to try some Piezos.
