http://www.arceurotrade.co.uk/Catalogue/Stepper-Motors The 180Ncm will be big enough, and at £18.50 at the moment ... The 3 Amp driver at £28.95 each are a good option for driving them, so for under £150 you have all the grunt. They will run direct off the parallel port, but a simple breakout board will be useful, and all one is missing is some DC power. 35V at a few amps does not cost a lot. -- Lester Caine - G8HFL ----------------------------- Contact - http://home.lsces.co.uk/lsces/wiki/?page=contact L.S.Caine Electronic Services - http://home.lsces.co.uk MEDW - http://home.lsces.co.uk/ModelEngineersDigitalWorkshop/ Firebird - http://www.firebirdsql.org/index.php ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
