#173577 - I was wondering has any one ever |
Hi to all members: Has any one ever made a proximity card reader using a 8051 core part with LCD readout using 125 Khz frequency? I wanted learn about proximity card readers a year ago but all the units I saw were Pic parts ex. Joe Grand's proximity card reader designed for parallex Company. I was hoping find one using a 8051 core but I have not found any cheap ones. I did find one on ebay that uses usb port to show readings for $18.00 but it take month to get here. So while am waiting thought I try to make one. If it not too differcult. Best regards, Ralph Sac |
