RPM Ratio Finder

Search for:

 Input the RPM ratios you need! Press enter after typing each value to add it to the list of searched ratios. You can change the settings before inputting a new target if needed. Decimal points and simple operations are supported (parentheses, +, -, *, / and ^). Once all the values you need are in the table, you can start the search with the check mark button.

 It's not always possible to reach the exact value using Adjustable Chain Gearshifts. The accuracy of the search is how much leeway you can afford in the approximation; however, a smaller amount of leeway results in a larger sequence (less compact setup) and it takes longer to find.

 You can decide to enable or disable results that are greater, equal or lower than the target. This is useful if you need a ratio ever so slightly larger than the target, for example.

 You can check the settings for each target individually by selecting them in the table. If something's wrong about a target value or its settings, you can delete it from the table using its X button.

 When enabled, any valid results in the history can be used in the search process, saving time. You don't really want to disable this unless you're specifically looking for a shorter sequence than one of the results in the history, using a lower accuracy than the previous search.

 This is the list of all the sequences you looked up this session, and their corresponding ratios. Just in case you clicked "New Search" a bit too fast!

  • ACG sequence: redstone power to feed the input and output of a set of Adjustable Chain Gearshifts. Don't forget about analog levers!
  • Gear changes: number of times to double or halve the rotation speed.
  • Results highlighted in green perfectly reach the target ratio, instead of being an approximation.

 Any order works, but to avoid going over 256 RPM in the middle of the sequence, it's best to put in the steps that slow down the rotation first. There can be several valid sequences for one target. Below, there is an example of a setup for each sequence in the table. There's no need to copy everything block for block though!
