Computer scientists at Southampton University have built a supercomputer out of 64 Raspberry Pi credit card-size computers and Legos. Separately, the Open Electronics community has recently been offered a GSM/GPRS and GPS daughter card suitable for attachment to the Arduino microcontroller board.
And while we are on the tack of low-cost access to computing Futura
Elettronica is selling a GSM/GPRS plus GPS daughter card for the Arduino
low-cost microcontroller board.
The board is an upgrade from a
previous GSM shield board – I don't know why they call them shields
though. The board is based on the use of a SIM900 or SIM908 component
and allows Arduino-based systems to make voice and data connections via
One key change from the previous GSM shield, according
to the vendor, is the inclusion of two 3.5-mm connectors for a
microphone and headset allowing users to make a voice call, network
In other words it is possible to build a
clunky-looking mobile phone based on Arduino. It is not entirely clear
but it may be possible to insert a pay-as-you-go SIM card, or indeed one
lifted from your mobile phone, into the assembly.
It is not
clear how sophisticated the set-up and you may have to do some coding
and jumper setting to get all the bits working well together but the
vendor states categorically "you can make a voice call!!" It is also
clear that it will be a lot less cost than a price plan for an Apple
iPhone 5, but it is more or less cool?
