To investigate the development of a non contact RPM counter for elements with an arbitrary number of “spokes”. Using a modulated infra beam and detector. With an upper limit of 20,000 RPM, a lower limit of 500 RPM and a resolution in the range of <=5 RPM The transmission/receiver system should be designed to be robust in terms of use in an ambient environment i.e. it should not need to be used in a dark box. It should have an appropriate GUI and UI to enable one handed use. Consideration should be made for power consumption in terms of automatic beam strength, transmission time and clock speed. It is expected that an LCD display, microcontroller and IR diodes/receivers will be used in the project. Some consideration of save usage should be made. Once this has been successfully developed the student is to investigate the use of correlation techniques to try and automatically identify the number of “spokes” by the differences in the return patterns, trying to identify the 2 pi events. At level 1: A working IR transmitter ( using a modulated IR beam of some form) and a working receiver capable of monitoring a rotating element, ideally producing an output compatible with the PIC A2D or a similar method to integrate with a PIC based system At level 2: A PIC and LCD interface providing control and output from the sensor system with an appropriate display and GUI At level 3: Improved receiver/transmitter interface demonstrating improved range/resilience to ambient conditions. At level 4: Use of correlation techniques to look for repeating patterns in the IR return to allow automatic calibration for any arbitrary spinning object with irregularities. Hints in terms of initial RPM can be given if required. Equipment Required: Type 18 PIC IR TX/RX ICD 2 or Pickit 3 General Components Op Amps / C / R / L / IR TX/RX

HI, I have designed, in the past, many pulser counter for different applications. About the components you want to use these are just the components, programmers... that I would suggest. No problem at all thank you in advance maurizio stefani
