#174356 - it is overkill Responding to: ???'s previous message |
using an FPGA is just a decoder with a pair of HUGE counters which anyone can do.
How fast are you going to close the jaws on a pair of digital calipers? not very I wouldn't have thought. Just as a side thought which has always interested me random thought moment coming up, on a pair of scissors when you close them the point where the blades cross can be moving faster than the speed of light.mainly because its not a physical thing its just an arbitary point.You learn something new everyday ;-) To get it to work you need very long blades, say a light second long and the handles an inch apart, you close the handles in less than a second and Bob's your uncle, although what this would look like is open to debate:-) |
