Warning

This is the documentation the latest work-in-progress version of MPF!

This is the documentation for MPF 0.56, which is the “dev” (next) release of MPF that is a work-in-progress. This is probably ok, and means you’ll be on the latest, cutting-edge version of MPF.

However, if you want a more stable version, select the v:stable version from the lower-left corner of this page, which is the most recent version that is not getting new updates.

If you are new to MPF, we have recently rewritten the installation process which only applies to this “latest” 0.56, so you probably want to stay here because the prior installation process doesn’t work on the latest OS and Python versions.

Slingshots

autofire_coils:

Slingshots are configured as autofire_coils in MPF.

Hardware

../../_images/slingshot_side.jpg ../../_images/slingshot_front.jpg

A sling shot usually consists of two blade switches and one coil. Those switches are wired in parallel because it does not matter which switch was closed to fire to slingshot. Connect one side of each switch to ground and the other side of both switches to the same input.

Part numbers:

  • Data East/Sega/Stern: #500-5849-00
  • Spooky/American Pinball/Suncoast: PBL-5849-01

Config

This is an example:

switches:
  s_sling_left:
    number: 5
coils:
  c_sling_left:
    number: 7
    default_pulse_ms: 15
autofire_coils:
  ac_slingshot_left:
    coil: c_sling_left
    switch: s_sling_left
This example is tested to be valid MPF config. However, it is not integration tested.
switches:
  s_sling_left:
    number: 5
coils:
  c_sling_left:
    number: 7
    default_pulse_ms: 15
autofire_coils:
  ac_slingshot_left:
    coil: c_sling_left
    switch: s_sling_left

Adjust default_pulse_ms and default_pulse_power in your coil to control the strength and sound of your slingshots.
