RFID hits the ShoutBox

Just wanted to share this........

 I bought a new RFID reader .......

It installed quite nicely all by its self  as a HID (Human Interface Device)

Now i was clueless "Wot2Do" with a RFID HID.... soo.....

.... yes ask the ShoutBox someone will point me in the right direction......

... there i was waiting....waiting.....waiting...... thinking everyone was having coffee break or had fallen off thier chairs.......

...per chance i waved the RFID token around the Ether and over the reader as well....and...and...and....

the ShoutBox lit up and a new entry was blipped up.........

...... not just an ordinary entry but a whole series of numbers........

.... who the heck was sending a string of numbers to the shout box i asked disbelievingly......

closer inspection showed it came from Gareth..... wait a momo .... i am the Gareth......... wait a big MOMO that was Gareths RFID Chip talking to the ShoutBox including CRLF.....

Now this Seems to open up a whole new "Jar of Grubs" ..... read the question after the ShoutBox discourse.

What would "YOU" use this type of  "Data Entry" for ?

Well I thought you had the rfid modules alone.

My idea was to make an intelligent tv remote control  or for everything like tv b gone but with an extra function .

If you passed an rfid tag in front of it it will do your favorite things , meaning to go to your favorite tv channel

to your favorite radio station, adjust the lights of the house like you want them , e.t.c .

Your favorite thing will be saved in the form of a string in rfid tag's memory .and you can programm it

though the remote controll too .

Thats it .

 

I think i see where your arriving ... neat ideas...

Then each person ..... wife/hubby/partner/cat/dog/buggie would have thier own personal tag attached to thier body/mobile/catflap/perch........

..... then a quick swipe over the RFID reader whilst sitting in your favorite armchair or hammock and........ intstant personalised environment....lights-music-coffee.... neat......until the cat bursts through the cat-flap setting off RFID cat-flap  alarm ....frightening the bugie that then flys over the sensor too......

    I have see some Car-seats and TV chairs that self ajust to a setting the person preprogrammed - so intergrating your idea would be straightforward when tied into an InfraRed ready picaxe/arduino/propeller.

I have seen Laptops, like ones you get from work, that have RFID readers in them. So then you have to swipe the card over it and then the laptop opens locked files for you to use. You could use that on your elvish computer Gareth. You could swipe the card to lock the computer or do some other feature. Maybe have it turn on a robot when swiping it.

 

As we speak i have already hacked my RFID reader and have access to the raw data...... all 19 bytes of it for one card yikes....

.... It seems that only 8 bytes actually change from card to card.... so its not so yike_ish.

Yes your idea with swipe over robot is neat idea.... it would be a means of non invasive switching....... so your super streamlined robot would have no visible switches.... or used as "kill the power" badge..... or as an "Arm" switch.

Currently my RFID reader is fixed to my working computer _ as its a HID device it will TX direct into active selected text boxes .... ideal for password entries :-)

Perhaps different robot personalities, depending on which card was most recently swiped?

Didn't know about these tv chairs I have only heard about the car-seats .

I will make something like this one in the future(meaning in 1 year about ) for sure .

 

Seems like an concept pregnant with potential.

Perhaps an RF reader equiped robot will report its location or encountered objects as it wanders around? You could write a Processing or other app to capture the RFID and map it to a defined label, so that reported objects are more human readable.

Build a swarm of robots that are all RFID tagged. As the swarm goes about gathering navigational mapping data, they return to a central point, are identified by their RFID, and supply their collected data. In this way the swarm builds a map that can be uploaded and shared with the others, or with a central host.

I have 2 different types of RFID chips.

  1. Creditcard size   :- detect range 0001837321 (that was the chip writing into the box)  10CM
  2. KeyFob    size   :- detect range 0022927691 (again yours truly )                                5CM

So this gives an idea of detect range if attached to a Robot.

The Swarm idea i like very much, as the Master controller has to just sit there whilst the "Madding" swarm runs rings around it.... (being very dependent on the info that it is "Fed" with).

Oh, and as the Master builds a better and better map, it can direct the swarmbots to explore the least well mapped areas!
