Verdict: Capable and surprisingly reliable. Inexpensive enough to buy to try. Pros: capable of fast logging through the PC parallel port which also supplies its power. DrDaq offers USB-like reliability

Cons: DrDaq is a raw circuit board so this needs working round. Software works well but its approach is unlike other systems

Future proofing: DrDaq is Pico Technology’s first data logger for schools. They are well known and respected for their scopes and products for industry.

Pico Technology make the innovative DrDaq logger which by connecting to the computer’s printer socket, records at the break neck speeds much sought by physicists. Priced surprisingly low, it has a fleet of built-in sensors and sockets for other sensors you may have. A bit clunky in appearance ("Heathkit-like", said one teacher) – you could afford to get one of these and have fun-a-plenty. You can then evaluate whether to get more. While DrDaq doesn’t hit me as a mainstream data logger for science experiments, it has never once let me down. It is too easily overlooked

There is an adapter for advanced physics students to make up their own sensors. The Pico (www.drdaq.com) web site contains a generous heap of experiment notes for using loggers and oscilloscopes. While you’re there, take a look at Pico's parallel port 'scopes which get good reports from physics colleagues.

I’m told that DrDaq can connect to a web server for real remote logging – but that’s as far as the info goes.

Compared to everything else, Pico's software works and thinks differently. However you can download it and check to see if it’s for you.
