Read full description

LinkControl is an automation application that can be used to control lights, dimmers, motors and other physical devices. This application is essentially a button processing application that needs to be paired with a server component that ultimately controls the physical devices. This application downloads button definitions from the server application and when a button is pressed a button identifier is returned to the server indicating which button was pressed. With that information the server decides the appropriate next step. LinkControl has no knowledge of the overall process as it just handles button definitions and button presses.

About

SpringRithm

  • Calculate dynamic spring loads
  • Determine preload adjustments
  • Check for coil binding
  • Access spring database
  • Save time on setup changes
Read full description

SpringRithm is for anyone who has a coilover suspension. With a purchase subscription, SpringRithm allows users to be able to set up their coilover suspensions to their desired loads at their desired ride heights. SpringRithm can assist users who do not have access to a coilover testing machine/Spring Smasher to get their coilovers correctly tuned to get the right loads. SpringRithm not only outputs the dynamic loads that the springs will see in travel, but also tells the user how to preload the coilover nut in order to achieve the set load/loads. For users who do have a coilover testing machine/Spring Smasher, SpringRithm will save tons of time by instantaneously allowing for spring rate and load changes in order to find new setups and figure out how their dynamic loads are changed. SpringRithm also has a built-in database of springs in order to determine if stack setups will coil bind so that users will know if their setup is even theoretically possible. Why guess on what height springs are needed for a setup when you can know!
