Lever Frame Update....

I've been intrigued with lever frames since I first saw them and wanted some on the layout.  I designed some a couple years ago that can control a turnout mechanically with a fishing line to the turnout  but wanted some that could control a servo controller and servo for turnout control.  These do that with switches in the lever frame controlling a $2 servo controller which intern controls the servo under the turnout.


More info on other options to do this on my site ( HERE ) and if there is any interest in this version I'll put the print files up on thingiverse.

"Current" servos use PWM for control. (Most build in last 20-30+ years. Older ones are total analog units.)
The 555 chip can be used for PWM and if looked at bottom of your "Servo Tester," likely find that. If can't read a number for whatever reason, like maker scrape the numbers off, other parts & wiring will show.

Some "Switch Motors" are the same with 555 and servos in 1 box. (And High Cost to buy them.)

Many ways to mount the servos beyond under the table. Some I've seen are hidden in buildings, scenery, and more On the table. Servo Doesn't need to be near the track or use strait wire between them but that's easier.

Yep besides ....



..... the under turnout bracket above (1 or 2 limit switch options) .... there is .....



...... the option of a horizontal mount show above ...... or ....



... this vertical one that mounts on the side of the fascia or some other place and you can bury the control wire in the layout's surface.

More info on the ones above along with print file links.....

The Lever Frames could control any of the above.
