This is a Physical Hit Counter V2. In this version I use MAX7219 and 7-segment common cathode LED display x 8 instead using mechanical counter like the first version. MAX7219 is a 8-Digit LED Display Drivers and serially interfaced.I use MAX7219 because I got two samples from MAXIM.To interface MAX7219 with PC serial port without MCU, we must convert RS232 voltage level to TTL level.

This is a physical hit counter.It used to count page-hits on the website instead of using software only.The counter will be connected to rs232 port through a few of electronic components that performs as a counter driver and power supply circuit.The counter that I used is a mechanical counter or electromagnetic counter model SC-212 which I get from an old coin-op game machine as show in the photo.As the counter’s nameplate specified, this counter requires 12VDC power supply, this means that it requires a 12V pulse to increase the counter by 1.Also,the in the nameplate show the maximum speed is 15 CPS, but I not use beyond this speed in my project.
