Could you tell me more >about it? When you get a chance that is. It uses a 16C84 feeding an LCD display, the actual sensor used in the article was a 'magnetic field sensor' type FGM-3. This has a frequency output dependent on the magnetic field strength detected, for the article a PLL circuit was added to give a conventional 'pulse per rotation' signal. Any other type of sensor could be used, a reed relay and magnet would be somewhat cheaper :-). The code can be downloaded from their website as before, the project is called 'PIC-Agoras'. I've zipped the two circuits together, and here they are.
