Well…. You can’t blame me and the other people like me, if you make cool toy that has a cool technology you can’t blame us for checking it out and figuring it out…..

Well, I took my previous project using a RDM6300 and a raspberry Pi and I added some 5050 LED strip lights…..I planed on making the lights do something different based on the RFID that was detected….so I needed some EM4100 RFIDs to read and mess with….so I found certain Kyber Crystals from the big D place just happened to have EM4305 RFID chips in them that could be read as EM4100s. I did similar wiring to this page here. But I specifically used GPIO pins 23, 24, 25 to control the RGB of the 5050 led strip. Then I hacked up this python code here (I borrowed some of it from the link in the last post about using the RDM6300):

My kids have actual Holocrons that work with the Kyber Crystals so they weren’t supper impressed….but heck I made this one from scratch. Now I just need to put it all in a fancy box or something….maybe…
