Changing the two capacitors didn't work #1

Maybe I'm doing something wrong.. I'm trying to modify this reader in order to use the HID cards, because we already use them at my workplace and I want to keep as much as the existing infrastructure in place.

I did change the two capacitors, but was not able to run your script, just yet. I used a basic serial reader. I'm using Arduino Uno and the other tags work just as fine, after the changed capacitors, but basically does nothing when I'm using a HID tag.

So, these work image

but any card, of any kind.. does not image nor these image

I had no way of contacting you, but this.. so, please.. any idea would be welcome! jazmine.moku@gmail.com

Thanks so much!

If anyone else ever reads this...

Those cards should work. However, the encoding of the card requires a separate processor sampling the raw input to decode them. The processor on the reader does not decode the HID tags at all. The HID cards/tags use a different encoding that the RDM6300 is not capable of decoding.

The signal to the Teensy (or equivalent) should be picked up at pin 7 of dual op-amp. This should be connected to whichever pin is used for the rfid value when creating a TagParser.
