buzzing! - servo turns off at end of throw
setup - center the servo and mount - no alignment needed
with DCC or the included fascia controller
the DCC address with a jumper - no CVs to program
The singlet has a baby brother, the Micro Singlet. It is a simple servo decoder
designed to drive turnouts and only turnouts. It solves the problem of servo buzzing
by turning the servo off at the end of the throw. Special circuitry and programming
has been built in to accomplish this without a large jerk at restart.
The Micro Singlet works has a fascia controller for controlling the turnout manually.
It is the same fascia controller used by my other servo boards. The Micro uses
a pushbutton to throw the turnout. If you are in love with toggles you will need
the older Singlet (see below) or the SwitchWright.
Installation is simple. It is designed to work with a servo under the table using
the geometry of the SwitchWright bracket. This mounting method provides an over
the center spring action that keeps the points in place after the servo turns
off. After years of trying various methods this method really works the best and
avoids the servo buzzing that happens when they are fighting to keep the points
in place. Centering for mounting the servo is done by holding down the fascia
controller button until the servo drives to the center. A tap on the button releases
