ubiq_uitous communication, wearable and multimedia systems

The DisplayLink display also works with an NSLU2 (running Debian) and a beagleboard.

The beagleboard can use the binaries generated on the NSLU2.

The photos have notes on Flickr.

As part of attaching a full graphic LCD display via USB / DisplayLink - I made some experiments with an ASCII only version, aka
SlugTerm.

The FTDI USB245BM provides parallel output to its data lines and is e.g. supported by the lib-ftdi library on Debian.

Adding external displays via USB is a quite flexible option.

Started with the original support on Win and OSX - but aim to use this on Linux with e.g. a beagleboard.

A Bluetooth enabled zeemote JS1 controls a servo - no PC involved - there’s just an ATmega8 micro controler coordinating things.

Whereas originating an RFCOMM connection from a Linux system using the Bluez stack was familiar to me - I never did things the other way round.

The screenshot shows how a serial connection gets advertised with sdptool, a OSX system connects using minicom and finally there is a duplex connection with the “screen” utility on the Linux side.

Best viewed on Flickr in “original size”.

Assembled two versions of a robotic vehicle that uses a mobile phone (Android G1 or Symbian S60 Nokia E71)

The first version uses an Android G1 - may communicate via its serial port or Bluetooth.

The second version makes use of Python running on recent Symbian S60 devices. It may use Bluetooth or IrDA for the “phone 2 motor control” communication path.

A “nut core” (ATmega128, as used in the BTnode alikes) combined with wireless communication alternatives (nRF24L01 or ZigBee). The nRF24L01 can talk to the sputniks shown on the left.

I2C is an interface usable on multiple platforms - e.g. LEGO NXT, Arduino, PicAXE.

Using a standard connector new combinations can be tested quite easily.
