3 stepper motors from 1 board

-

i'm akshay , i'm working on project on controlling 3 stepper motors.

i have ordered an  arduino mega 2560 board, along 3 easy drivers (sparkfun) , 3 5v stepper motors. can run 3 motors no external supply (i.e on supply provided board) results? board overloaded?

that depends on how current stepper motors require.  if run arduino usb power have 400 ma left on other devices.  if run arduino off external power can draw 900 ma before regulator overheats.

i'm guessing  need external power.

what exact steppers using?

Multithumb configuration params not working? - Joomla! Forum - community, help and support

hi, i've installed multithumb 1.1 on joomla 1.011 site , works fine in basic set-up (and jce-editor). except when try tweaking mambot params, things stop working. specifically: if use "only in these categories" setting , fill in categoryname, e.g. "news", pop-ups/thumbnails stop working, categories, including "news". if use "not in these categories" these categories still use pop-ups. if select "use thumbnails" "no" not no thumbnails no pop-ups anymore. so way use multithumb selectively use optioni "apply content {multithumb}", bit cumbersome. there more people having these issues? hi bikey, i having issues bit different - yet same.  saying have way set configuration plug-in.  not know how find cong this.  if can maybe read posting - don't bore process.  jce editor - have not installed - still using default html editor - cant recall name.  why not see config file? anyway - find if use static page , pass com
