A calculator for figuring out how many items should be used when building a hopper clock. This is inspired by a page that has sense gone off line and as it was an invaluable tool i decided to make a copy for myself. Using this calculator is as simple as entering the time you would like to have in your timer circuit and pressing calculate. This will give you one of 2 options: a ethonian hopper timer and a single stage cascaded hopper timer. The tool will calculate the estimated time for the clock to run as well as give you the number of items in each stage.
Simple Hopper Clock
This is a simple hopper clock used for timings between 0.8 seconds and 256 seconds. for clocks longer than 256 seconds the cascaded hopper clock should be used. The items can be placed in either hopper and they will cycle back and forth. For more options see the wiki If you are on Minecraft Bedrock Edition you can grab a structura pack file below (structura is a resource pack generating tool that is like litematica, the link below is the resource pack that attaches this redstone contraption to an armor stand for helping you see the build).
Cascaded Hopper Clock
This clock is able to produce delays up to 18 hours. It is less precise than the simple hopper clock. The above calculator attempts to achieve the highest accuracy, note that the higher the timer length the lower the accuracy of the timer. For more information on this see the wiki If you are on minecraft bedrock edition a structura pack is available below(structura is a resource pack generating tool that is like litematica, the link below is the resource pack that attaches this redstone contraption to an armor stand for helping you see the build).
