What is a Dropper Automatic?

Dropper posts make mountain bike riding more enjoyable and easy. They allow riders to drop the saddle to a lower position for easier pedaling, especially on steep terrain.

The dropper is a simple Redstone contraption that can be used in many builds to automate items. It has nine slots that can be occupied by items when activated with a clock circuit.

Accuracy and Precision

For the best accuracy and precision, a dropper automatic is the way to go. It can dispense small amounts of liquid or substance exactly where you want them and will give you exact measurements every time. This is especially important for medical applications, where a slight variation in dosage can have serious consequences.

In order to get the most accuracy and precision from a dropper automatic, you need to understand how it works. First, you need to know that it has nine slots for items. However, it can only eject one item at a time – even if multiple slots are filled. This is because a dropper has a delay of 2 redstone ticks (4 game ticks, or 0.2 seconds barring lag) between being activated and triggering an output.

To solve this issue, you need to set up a comparator and a repeater. The comparator will provide a Redstone signal to the repeater, which will trigger the dropper automatically. You can use this loop to get an accurate, precise dropper in your base.

Another great way to improve the accuracy and precision of your dropper is to add a clock circuit to it. This will ensure that it only ejects an item when the output side of its inventory is empty. You can also use this loop to make the dropper work in “Pulse” mode, which will dispense items when it receives a pulse.


Whether you’re on the descent of a technical mountain bike trail, or just punching up rocks and roots, a dropper makes riding a lot more fun. The ability to drop your saddle halfway dropper automatic down allows you to ride more challenging terrain while staying safe in the process, as it eliminates a big chunk of your body weight from connecting from your back to your front bike frame.

Most dropper posts work with a cable connection between the post and a lever located on the handlebar, but there are more advanced options that operate wirelessly (RockShox Autodrop) or hydraulically using pressurized air. No matter what type of system you have, most offer several safety features to protect the user and prevent unauthorized access.

Safety features include a mechanism that requires a key to activate and eject items from the inventory. Once activated, a dropper waits 2 redstone ticks (4 game ticks or 0.2 seconds barring lag) before ejecting an item. It does not continue to eject items while it’s activated, and additional inputs during this time are ignored.

The safety feature on the Dropper10 also includes a safety pin that must be manually inserted into the bottom slot and then rotated 90 degrees to lock/close the hook and turn the LEDS from green to red. This ensures that the hook cannot be opened while the dropper is in transport mode.


Dropper automatics are expensive, but they save time and effort compared to manually inspecting the posts in the course of a rail operation. They also reduce the risk of injury from falling overhangs. They are not for everyone, dropper automatic however, and require a disciplined approach to maintenance that focuses on cleaning and replacing worn components. Dropper posts should not be powered-hosed after muddy rides, as this will embed granular contaminants into the seals and bushings, increasing their friction.

Activation occurs by either one of the methods above or quasi-connectivity[Java Edition only]. The dropper has a 2 redstone tick (4 game ticks or 0.2 seconds barring lag) delay between being activated and responding to an input signal. During this time, additional inputs are ignored. Once activated, the dropper ejects an item into an empty slot. Depending on the current state of the dropper, this may cause the machine to move up or down repeatedly until it reaches its desired position.

Industrial Applications

The dropper automatic is a small device used to dispense liquids in small quantities. It consists of a tube with a rubber bulb or pipette at one end, which is squeezed to draw up the liquid and released to dispense it in drops. It is used for various purposes, such as dispensing medication and eye drops. It is also widely used in scientific experiments and the beauty industry for applying essential oils and serums. It is available in a range of sizes and shapes, and some are reusable while others are disposable.

The basic dropper can be built using a redstone circuit and 2 redstone blocks or 4 game ticks (0.2 seconds barring lag). It must be activated with a clock to eject items, and it cannot eject more than one item at a time. When an item is ejected, it resets the dropper’s inventory. If multiple slots are occupied, a random slot is chosen for ejection each time.

The KKP Auto Loading Eco Dropper is made of 100% recyleable olefin-based materials and offers an elegant design with high functionality. The mechanism allows an automatic load as you screw open the bottle, streamlining the process and minimizing the amount of user effort. The dropper is designed to be environmentally friendly and meets the requirements for most cosmeceutical formulations.
