Jumpy. I left the center? ground open, then drove the 3 leads that had most resistance WRT each other, thinking they were the edges of a Y configuration. Perhaps try grounding the center, then just pulsing the other 3 wires in sequence? That would be much simpler than the 6 transistor bridge I have for BLDC. (Actually 9 transistors, since the high side transistors each have another transistor to switch them.)Anonymoushttps://www.blogger.com/profile/12442293148812300835noreply@blogger.comtag:blogger.com,1999:blog-2131958746786008795.post-77158262675100948862012-06-20T09:56:45.811-04:002012-06-20T09:56:45.811-04:00You can use the magnets from inside your HDD and a...You can use the magnets from inside your HDD and a 75 cent reed switch to get that stepper motor spinning super fast.<br /><br />Here's the video tutorial: http://jaytube.org/share/PueF3b3XXBoSpottedMarleyhttps://www.blogger.com/profile/15007244310761194192noreply@blogger.comtag:blogger.com,1999:blog-2131958746786008795.post-10330009914397288972012-01-26T05:21:08.690-05:002012-01-26T05:21:08.690-05:00Hi, Good Job, will you please post schematic of yo...Hi, Good Job, will you please post schematic of your circuit for better understanding.Luckyhttps://www.blogger.com/profile/13900686848102825457noreply@blogger.comtag:blogger.com,1999:blog-2131958746786008795.post-10852980999358251042011-03-27T15:07:51.797-04:002011-03-27T15:07:51.797-04:00If you are not already bored with this project, yo...If you are not already bored with this project, you might look at this: http://www.atmel.com/dyn/resources/prod_documents/doc8012.pdfRuss Ferridayhttps://www.blogger.com/profile/07920595958351247196noreply@blogger.comtag:blogger.com,1999:blog-2131958746786008795.post-9045673912726758552010-12-23T02:22:55.188-05:002010-12-23T02:22:55.188-05:00Hi, your web site is great!
