Open Trickler: The DIY Smart Powder Trickler

[@whalen83]

Nice work! Have you considered making an analog version that works with a balance scale and uses the phone camera to watch the beam and trickles till the beam lines up with the zero mark? This could get almost anyone into an automated powder trickled for very little money.

[@pstewart5443]

This is quite possibly the best idea for reloaders on a budget. You could make your own 0.02 accurate throw for less than $800. Great job!! Using this with the Ingenuity Precision Trickler would be a great combo.

[@accuraoutdoors1561]

That's a really cool setup. Now to add in a powder throw for faster powder measures.

[@Ammolytics]

If you're interested in adding support for this, contributions are welcome!

[@AntonSavelyev]

Have you considered making a video on how to build one of these from start to finish?

[@Ammolytics]

Good suggestion! For now, I'm trying to get things a bit more stable and easier to do (e.g. pre-built image for the SD card). After that work is complete, I'll do a quick follow-up video and show the build process (maybe in fast-forward or something). It's a straight-forward build, but some folks learn visually and I want to support that.

[@jcims]

Awesome work, really love the scale integration. Thanks for posting, hope to see you more on here!

[@Ammolytics]

Definitely more coming very soon!

[@user-vu1to8jd3t]

Awesome stuff! Thanks for sharing!

[@Ammolytics]

Thanks for watching!

[@interstellarsurfer]

Beautiful work! 👌

[@Ammolytics]

Thank you!

[@bsshep1]

So I would like to build this but some of the components you linked to are not available on Amazon. Could you provide an updated parts list?

[@Rico11b]

I wonder if this would work with other scales of this type that have an RS232 port? Like the Creedmoor TRX 925 Reloading Scale. Have you tested it with other scales?

[@beardedcobra4898]

I m looking to build me something like your nice setup here :D Thanks for sharing! Is there a good budget option for the scale?

[@Ammolytics]

Yes, the Creedmoor scale is supported. www.creedmoorsports.com/product/creedmoor-reloading-scale-trx-925-precision/creedmoor_sports_brand

[@beardedcobra4898]

@@Ammolytics thx for the tipp! 😃 i am looking to mabey build something more in the direction of the autotrickler v4 😃

[@jasonmays8825]

Love it ! I want one ! How much ?

[@sergeleduc3755]

nice work, i had somting started in phyton, but think am gona explore the Node-RED route :D, so anyting with a web browser will be able acces it ;)

[@traviscornett1963]

Subscribed and eagerly awaiting the aforementioned updates. I've built all the components, but do I need to login to the Pi Zero to setup Bluetooth. The app doesn't seem to be able to find the device automatically.

[@garydelnevochannel]

Excellent! Will it work with any A&D scale, specifically the EJ-54D2?

[@OE8ZZZ]

Very nice job! I only own a PI 3 B so how can I install the program to my existing PI-image? Thanks for your help

[@806Guns]

Can we use this on the new creedmoor sports scale?

[@Dpix1990]

G'day Eric, I absolutely love your work! Have you ever looked at Chinese balance scales? The are claiming accuracy in line with the a&d or satorius, but at 1/4 the price (they are still an electromagnetic scale rather than load cell) and have RS232 or USB out/in

[@Ammolytics]

Interesting! I haven't tried them myself, but I'm open to it. You can find my email address on my website -- send one over with any details that you have and I'll be sure to check it out. Thanks for the heads up!

[@gdog4323]

Hi... did you ever get around to trying a Chinese version?

[@gdog4323]

Hi... did you ever successful try a chinese version scale?

[@amaftershock]

Any thought of selling them or showing us how to make one?

[@1clnsdime1]

What happened to some updated wideos. I can't find the parts list.

[@Ammolytics]

The most accurate parts list and instructions are available on GitHUb github.com/ammolytics/projects/tree/develop/trickler A lot of progress has been made on this project recently, with help from the community. Once things are a bit more ready for general use, I'll share an update video and article. Until then, come by the Discord channel (linked on my website) to join in and learn more!

[@HexagonGroupWarszawa]

Hello, Can I use raspberry pi 3 B+ instead of pi zero w ?

[@ionskull13]

Anyone know what stand he is using. Just call all the parts to start a build. The Pi was hard to find :)

[@Ammolytics]

The stand you see here is just whatever I could find to give it more height. The trade-off with trickling in from above like this is that the extra distance created a lot of lag on the system, leading to overthrows.

[@ionskull13]

@@Ammolytics Thank you very much for this info.

[@edwardlance2379]

Nice idea, but it is agonizingly slow for the last few tenths of a grain. Manually controlling the trickler with an intterupted power switch you could top it off much quicker.

[@Ammolytics]

There have been a ton of improvements since this first release (which was almost two years ago).

[@whitehedr]

Any thoughts of doing an iPhone app?

[@Ammolytics]

Yes! You can actually try it out now through TestFlight -- details in this thread on GitHub: github.com/ammolytics/projects/issues/14

[@whitehedr]

Ammolytics I will check it out. Thanks.

[@stephanc7192]

amazing

[@robertgrassi6285]

holy shit that's amazing

[@Ammolytics]

Glad you enjoyed it, stay tuned for more!

[@keeper1959fem]

That's great work... I'm wanting to learn how to incorporate a unit like this to my sartorius, can you give me some guidance oh how to start?

[@uscbigdawg]

Eric, Do you have info on your drop tube design? Thanks for the Open Trickler!

[@Ammolytics]

Hey Richard, thanks for watching! By drop tube, are you referring to the funnel system I have attached to the top of my scale?

[@uscbigdawg]

Yes sir. The Trickler assembly is an easy read. Figured it’d be fair to include the cherry on top of the sundae. :-)

[@uscbigdawg]

I know it’s an Area 419 funnel and cup. It’s the cylinder above the lid and the drop tube that would be nice to know. Thanks again for open sharing this.

[@Ammolytics]

@@uscbigdawg I don't have parts numbers or dimensions immediately available, but it's a small metal funnel (like those used to fill a flask) press-fit into a short piece of copper tube (5/8" or so). Tell ya what -- I'm working on an update video/article to share the progress that's been made. When I do, I'll include more information about the drop tube for you and everyone else.

[@ThantiK]

Oh that's _really_ annoying only having the left-channel once you swap to the scale footage...I'd have at least copied the audio over to the right track.

[@Ammolytics]

Yeah, I'm sorry about that -- I don't know what happened. I'm still trying to get the hang of video editing.
