When I pick this up to update it one day, I will need to re-visit the library to fix that limitation.

With dynamic pages I only have about 4K used by the pages and I have over 20 pages being displayed. You should be able to impliment it in your server Doug regards Paul..

Its not an Arduino project it is writen in Bascom from MCSelectronics, code is posted on their forum free for all to use and I or others could supply the HEX code if wanted still a work in progress but already has a lot of usefull code.

The software emulates an EM4100 card. With some software changes it could emulate HID, but I don't currently have access to a HID card to identify the format changes. The parts list is part of the Instructables article that I pointed to. The micro is actually powered by a battery - I considered powering it from the loop, and decided that the battery was needed for local programming via the keypad. In another change, I did away with the 78L05, and simply used a set of CR2032 batteries to provide 6V - The device ran beautifully for a couple of weeks before the battery discharged (I would like to do some more testing with AtMega168 based projects to see how to get better battery life in sleep mode). And - yep - inductor L1 is the rx/tx antenna. The reader was simply the design published by Microchip for their RFID system - In my code, the manchester decoder is extremely unreliable (it takes multiple reads to get the data correctly) - so when I get that sorted correctly, I will publish it.

You should specify which type of 125Khz system it emulates. EM4100, HID Prox cards, etc. If it emulates Prox cards, does it support various formats (26 bit, Corporate 1000, etc)? Some questions: -Is a parts list available? -I assume the uP is powered by rectifying the signal from the reader (via bridge made up of D2-D5)? I saw the 7805 regulator but I assume this is just when using the debug port? -Is the receive/transmit antenna the Inductor (L1)? Or are there traces on the board that function as the antenna (I don't see any but figured I'd ask). PS: I would be interested in seeing your homebrew reader you mentioned that you used to get the data off the card! Thanks again, not many people are publishing this info online for us experimenters to learn from. Hello!
