RFID Part 2 - Multipass Cuckoo

Continuation of Hacked Multipass RFID reader ......

Now updated with absolute decode of the 19 byte "Secret-Cypher" hex string to 10 digit readable numerical string....YAY

RFID "Multipass"

RFID reader hacking success.... 19 bytes of raw data .......

Question is  shall i go Arduino or Propeller ? .....or even Picaxe (just in its grasp)

$2 Elfish computer "BlueTooth" Upgrade

For the cost of 4 resistors and a $1.80 Bluetooth dongle - your Propeller chip can join the wireless environment.

....again the Propeller chip just bowls me over with its amazing capabilities.....

For more details of how to accomplish this....... zip over to Elizabeth Scotts site

EDIT :- Now confirmed working with 2$ dealextream Bluetooth Dongle.

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......

Gareths Elvish Propeller Mini Computer Framework.....

I needed disparately a mini platform for development - the propeller can be easily set up to read ps2 keyboard/mouse and output a composite video signal, plus sound and if i play my cards right a usb bridge interface for my phone.

All i have basically done is sit the propeller usb board into an ic socket and soldered 2 IDE diskdrive sockets either side - allowing me to use the system like a breadboard for experimentation. On the back i have wired in sockets for mouse and keyboard.

My Wii-camera will just plug into the ide socket....... oh this is going to be soooo magic..

Walk this way (JMEWalker Clone)

I could not resist making a clone of a JMEMantzel walker (NOT the spidertank mech) as featured in his video Here.

This is just a mock-up to understand and tune the walking mech.........before.....

shrinking it to half (or quarter) its size - controlled by central servo for turning..............

The Barcode input method i will be expanding as well.

Do you think a picaxe 08M is up to the job ?      (servo-motor-barcode)

Megan40 - UltraViolet Detectors ( IR is going out of fashion )

Megan40 - UltraViolet Detectors ( IR is going out of fashion )

This is my latest FireFly codename Megan40 ...... because she sports 40MΩ feedback resistors

If you need detectors that are not affected by ambient light then i highly recommend using UltraViolet LEDs as detectors.

The detect circuitry is finished - next part is to shoehorn the picaxe 08 onto the back to control servo and UV glowtube.

"Jar of FireFlies" - 08 picaxe LM324 opamp Syncronisation

Here is FireFly C10 detecting the UV glowing light off FireFly C224

C10 then synchronises and flashes in unison with C224
