Building the perfect beast

A customer who buys his components from Rapid is playing a key role in the development of a transatlantic robotics project.


Russell Pinnington of 1337 Robotics, based in Anglesey, North Wales, has been working on the 'Electric Giraffe' project for the last year. Created by Lindsay Lawlor in California, the electric giraffe is a 17-foot-tall robot simulating the looks and mannerisms of one of the world’s most instantly recognisable animals.




With the ability to walk, see, speak, move its neck, respond to human contact and carry passengers, the self-styled ‘Rave Raffe’ (above) is a popular sight at robotics festivals and technology fairs, where it spreads the gospel about robotics and its coat of LEDs provides a stunning spectacle after dark.


The project is evolving all the time, as Lawlor seeks to build more artificial intelligence into his mechanical beast. Pinnington is responsible for the electronics and programming side – the MAKE controller that powers the robot’s brain. He builds prototype circuits, then sends the code, schematics and prototypes across the pond to Lawlor. The products he buys from Rapid include PIC microcontrollers, oscillators, resistors and capacitor packs. As Pinnington says, ‘just about all the stuff I needed to get started in electronics came from Rapid, even my soldering iron.’


Pinnington and Lawlor’s immediate plans for the giraffe involve adding GPS technology, and modifications to improve the articulation of the head, so ‘Raffe’ can look around and move his jaws when he talks.

Take the temperature of your PC


Exactly how hot is your workstation? As temperatures start to rise in offices thanks to the Spring heatwave, we have found a device that will record interior and exterior temperature and display it on the task bar of your PC.

Award-winning designer Alberto Ricci Bitti has designed a simple microcontroller-free PC thermometer that requires no calibration. Cheap and simple to put together for the electronics assembler, it can be plugged into any free serial port. The chief components, circuit schematic and instructions can be found on the Ricci Bitti website, but some of the capacitors, resistors and diodes are available from Rapid.


Hackers may like to consider how the PC Therm could be adapted to reflect the heat from your keyboard as you hammer out a self-righteous e-mail, or the fumes from your brow as you curse the entrails of Bill Gates after Excel crashes for the fourteenth time this session. Or is that just me?
