The OpenTrickler

Hi All

Attachment 249795

I'd like to share the project OpenTrickler that I've been working on for the last 3 years. The OpenTrickler adopted the AutoTrickler V4 design with following improvements:
- Free, and completely open sourced. You can build it at home with a functional 3d printer.
- Supports multiple precision scales. Currently A&D fx120/300i and G&G JJ100B are well supported. Others are being added by the community.
- Powder discharge system. A pocket at the rear can be used to discharge the remaining powder from the reservoir without needing to tilt the unit.
- Faster, yes, the repeatable charge time can be reduced to below 8 seconds per charge with proper tuning.
- Multiple interfaces. You can use your portable devices, tablet or phone to control the operation without needing to download the app. All operations are done from the web browser.
- If you're old school, you can use the mini 12864 display with rotary knob to perform simple charge/discharge operation.

However, you may not want to build the OpenTrickler because
- You need a 3d printer to begin with.
- You may need to be able to solder the PCB with components.
- You will need an compatible scale.

Eitherway, here is the demo of the live action

Awesome idea

That is a really inteeesting post.

The G&G JJ223BF just arrived. The scale costs around $500 which is significantly cheaper than the A&D fx300i.

I'm planning to build the OpenTrickelr for the G&G scale and evaluate the performance between two to see if the G&G is a good substitution.

Very very cool!

The G&G JJ223BF scale support is on the way.
