Title: EM interference.. ( This could happen TO YOU !! )
Post by: tp4tissue on Mon, 12 June 2017, 15:45:35

Left my keyboard (roswill rk9000 v2)   ontop of some stepper motor cables..

Suddenly the pc side spazzes out,  the calculator popped up, the windows media player sets off, scroll lock comes on and off..


All sorts of weird stuff...  Then the PC wouldn't shutdown..

Apparently stepper motor cables have enough watts running through them to Lock up the whole computer..



Stepper motors run on Electrical Pulses.

It crashed my Control pc, Through Electromagnetic Induction, Through the PS/2 connected keyboard..  Of which is merely laid ontop of them.

I'm curious, what are you building that is using stepper motors?
