7/12/2025: I have been very busy over the last 18+ months working on a new dispenser. Development is coming along but it's not quite ready for primetime just yet. Check the website for updates.

AutoDropper MK2 released

The AutoDropper MK2 is a major upgrade from the MK1 control unit. The MK2 features a 480x800 resolution 3.97" touch screen display. A new user interface allows quick and easy access to all system functions. The dispense screen displays all of the prudent information including current weight, target weight range, success rate, dispense count, average dispense time, last dispense time and dispense status. The dispense status is reported as on screen and by changing the screen background. The screen background changes to green if the dispense process was successful and red if it failed.

The AutoDropper MK2 supports over the air (OTA) updates via WiFi. The OTA updates are user initiated by first checking for an update from the system screen and then by applying it. System settings and load profiles are retained when upgrading from one version to the next. The OTA updates will allow for bug fixes and new features to be released as necessary.

The AutoDropper MK2 is an innovative, automatic, fully-featured powder dispensing system. This system consists of the bulk dispenser and the trickler. The bulk dispenser dispenses large amounts of powder quickly, while the trickler precisely dispenses small amounts of powder to reach the final target weight. The AutoDropper MK2 paired with the lab grade A&D FX/FZ series of balances is capable of dispensing loads in mere seconds while maintaining a +/- 0.02 GN accuracy. Works with all smokeless reloading powder types.

Features

• The system is standalone and does not require you to download any apps on your phone.
• Ability to dispense all types of smokeless powders including ball, flattened disk, extruded, etc.
• The system can learn from previous dispense cycles to automatically adjust parameters to reduce overthrows and decrease dispense time.
• Ability to auto-dispense. The system starts to dispense another load as soon as a empty cup is placed back on the balance.
• Ability to dispense ladder loads. The user can specify the number of steps, step increase and number of rounds to dispense at each step. The system will automatically adjust the weight based on your progress.
• Ability to store 15+ load profiles.
• Load profile includes ability to specify accuracy. By default the accuracy is +/- 0.02 GN. Dispense result within the +/- 0.02 GN of the target weight would be valid and accepted. This becomes important with powders with very heavy kernels such as N570, Retumbo, IMR 4350, etc. The accuracy parameter allows the user to adjust the valid result range.
  
  Example: Powder N570 has a single kernel weight of .08 GN.
  Weight: 70.00 GN
  Accuracy: +/- .04 GN
  Results in valid result range [69.96, 70.04] GN
• Integrates with FX and FZ series of balances from A&D including the 120i, 200i, 300i and 500i.
• Comes with replacement draft shields, thus eliminating need to modify original ones that came with the balance.
• No belts or rubber bands to adjust/maintain.
• Easy to clean.
• Designed and developed in Colorado.

Our Story

AutoDropper began as a personal project for myself. I purchased the A&D FX-120i balance to take my reloading to the next level. I already knew about two other commercial products that interface with the A&D FX-120i balance to dispense powder but I was not satisfied with their design, functionality and price. Being a software engineer with over 20+ years of experience I set out to design and manufacture my own powder dispensing system. While developing the system I decided to turn it into a product and offer it to the public.

MK1 released in 2023 used a 16x2 LCD screen and physical buttons.


MK2 released in 2024 uses a 3.97" touch screen and supports over the air updates.
