ITead Studio Foca and RDM360-UART

Just in from China :

The ITead Studio Foca V2.1 USB to serial converter and the ITead Studio RDM360-UART 125kHz RFID tag reader.

Together with the female connector wires from DealExtreme you can quickly build a test setup and read 125kHz RFID tags.

One complication : The datasheet for the ITead Studio Foca V2.1 is WRONG !

The incorrect connection diagram of the ITead Studio FT232RL board..
The incorrect connection diagram of the ITead Studio FT232RL board..

The wiring diagram does not correspond with the board. The correct pinout is on the rear of the board, the wires goes on top. Strange and clumsy.

The rear of the actual ITead Studio FT232RL board.

With the correct pinout the setup works like a charm.

LivingColors 1st generation

(This is a cut & paste from my old site)

The Philips Living Colors is a remote controlled 15 W. RGB led lamp.

It is available (April 2008) in the UK, The Netherlands, Belgium, France and Luxemburg for about 110 to 150 euro.

The build and design are high quality. This is not a re-labelled generic chinese designed product.

The remote uses a radio frequency transmitter and reciever om the 2.4 GHz ISM band from Chipcon (now Texas Instruments). It does not need line of sight and can control up to 6 lamps independently or as a group.
The microcontroller in the remote and lamp is a low power microcontroller from Texas Instruments. The comminication is bi-directional which suggests Philips has more products planned, say an AmbiLight – LivingColors bridge.

Philips owns Lumileds ( http://www.philipslumileds.com/ ), the manufacturer of the high power LEDs used in the lamp.

Lamp

  • MSP430 from TI
  • CC2500 : Chipcon / Texas Instruments : “Low Cost, Low-Power 2.4 GHz RF Transceiver Designed for Low-Power Wireless Apps in 2.4 GHz ISM Band” (see : http://focus.ti.com/docs/prod/folders/print/cc2500.html )
  • Luxeon K2 : Lumileds ( http://www.lumileds.com/products/line.cfm?lineId=18 )

I didn’t have the nerve to crack open the lamp itself.  Someone else did.
