Re: Motor for Blinds

["D&SW" <d&sw@xxxxxxxxxxx>]

You might reconsider your choice of motors. Look at using a cheap/used power
screwdriver. It will be slow, but will not require an additional gear train,
is easy to stop and reverse, and will have plenty of torque for raising the
blinds. Attachment could be a drum pulley to wrap the raise/lower cord
around.  The blade tilt cord but could use same pulley idea but  will be
harder to control.
