It is now over six years since the launch of Vela and the DTI scheme when 3500 schools purchased Vela for half price. Over 7200 Velas have been sold to secondary and higher education all around the world and there is now a resurgence of interest in the device. This article is a response to recent criticisms levelled at Vela.

This year marks the tenth anniversary in Britain of the first microcomputer interface for schools. This was a Commodore device, which had four digital inputs and four digital outputs and ran from the user port of the PET 2001 microcomputer via a set of simple control programs. The PET 2001 itself had 8K of RAM, its screen resolution was 4000 dots and it stored programs on cassette tape.

The aim of this article is to illustrate how data logging can be used to expound the topic of ‘uncertainties’in physics. This is done with the help of one specific mechanics experiment that forms an integral part of the Revised Nuffield Advanced Physics course.

The idea of extracting power from the wind is almost as old as civilisation itself, with records of existing windmills back as far as the 17th century BC, the time of the Babylonian emperor Hammurabi. Although mideastern countries possessed such knowledge, windmills were not introduced into Europe until the crusaders brought them back in the 13th century AD, but by the early 19th century there were 10000 windmills in operation in England alone.

‘Microelectronics For All’ (or MFA) was developed to introduce systems thinking to 11 –14 year olds. Some 40% of UK secondary schools have purchased MFA since its introduction in 1984. The basic concepts introduced by MFA relate to sensing (with input sensors), acting (with output devices), making ‘decisions’ (with gates), counting, pulsing and using a small memory to control a ‘music module’ and a Lego buggy.

Imagine giving a computer commands by speaking to it, or telling your telephone to ‘phone home’ and having it dial the number automatically! How about speaking into a small box in English and having the phrase come out in Spanish. This futuristic technology has arrived because voice-recognition devices are now available!

The original idea of producing a current/voltage graph on a CRO for the Teltron tube using VELA and an op. amp. was devised and reported by the first author in a VELA User Group Newsletter. The second author inspired by that report went on to devise a method in which the voltage was plotted in real time in proper units using VELA and a BBC micro. This article shows how the various ‘blocks’ solved different problems, while tracing the development of the circuitry towards the final system.

Control technology is an exciting new area for many schools and there are many commercial solutions available to solve the two main problems of how to control your motors and how to get your sensors to send suitable signals back to the computer. Just which computer and software to use is another problem. The range of equipment available for PCs for instance is enormous (and so is the cost in many cases!). For most other 16-bit computers there is little available, with the notable exception of the Atari ST (on which this article was written) with the Robokit, although even Apple is waking up to the possibilities of control work with the RESOURCE ‘Beeb-in-a-box’ add-on for the Macintosh.
