We've now added a color code for all accounts. Orange accounts are new members, Blue are full members, and Green are Supporters. If you get a message about a sale from an orange account, make sure you pay attention before sending any money!
Interesting idea! The main two reasons for connecting directly to the scale are 1) speed 2) reliability. Regarding speed, the A&D scale can be configured to update the display 20 times per second. Doing the image analysis that fast on your phone would be tricky. Regarding reliability, a text...
Hey everyone! I created a Discord to make it easier for folks who are building an Open Trickler to chat with and support each other. https://discord.gg/Bx3ynT This invite link expires in 1 day to keep out spammers, but feel free to email me directly and I'd be happy to invite you!
Hey SH! I published the second article in my series about sorting rifle brass. In this installment, I explain how I microstamped my brass to keep track of it over its lifespan, even through 24 hours of tumbling with stainless media. This method allows...
I was able to stamp 250 cases in about an hour with the drill press jig I used. Not terrible, but it wasn't expensive either. The first phase of any prototypical process are usually manual and slow -- it's not worth automating until you're certain that it needs to be done at a larger scale. My...
Hey folks, it's not worth arguing over on the internet. There's probably a disconnect here about goals. If your goal is to keep your brass sorted by batch/lot/group, then microstamping is overkill. However, my goal is to track individual pieces of brass (case # 1-100, not batches) in a way...
I understand that it's not for everyone. I explained the problem that I had and why I felt this was a good solution, as well as the pros/cons. I'm not selling anything here, just sharing what I learned along the way. For what it's worth, one local competitive marksman (F-Class, on Lapua's team)...
Hey SH! I published the second article in my series about sorting rifle brass. In this installment, I explain how I microstamped my brass to keep track of it over its lifespan, even through 24 hours of tumbling with stainless media. This method allows you to sort once by weight or other method...
The project is definitely alive and well! Most of the conversations about it happen over on GitHub: https://github.com/ammolytics/projects/issues You're not the first to ask about other scales. It shouldn't be too hard to support others that have serial cable support. See more in this ticket...
Based on the feedback from my previous experiment, I wrote an in-depth article about the accelerometer unit I built. Some folks asked me to share it here on...
As I noted in the article, this is just the first in a series -- a starting point. The Next Steps include comparing more cases of different brands, such as Lapua and Hornady, where I expect to see different levels of variation.
Agreed, and I have it listed in the next steps section, so I'll tackle that in the next part of the series! I'm certain that I have some velocity numbers for most of the times I fired these, but not all of them. I didn't want things to get too confusing up front.
Hey everyone! I published the first part of an ongoing experiment which explores the relationship between the weight and volume of rifle brass. https://blog.ammolytics.com/2020-01-08/brass-sorting-part-one.html The results were pretty interesting, and I was surprised by a few of the findings...
Quick update: A lot of progress has been made on the OpenTrickler project over the past couple weeks (holiday vacation). - An iOS app is ready for testing (PM me your iOS email address if interested) - A ready-to-go microSD image can be downloaded and flashed - The OpenTrickler code lives on a...
Hey SH! This seemed like the best topic on the forum to share this story under -- sorry if it's in the wrong place. This article is a little different than the kind I typically write. It's a story from my time competing at Camp Perry and what I learned about epic failure and sportsmanship...
Thanks for taking the time to read it! Regarding the charts: the LabRadar and MagnetoSpeed lines are nearly on top of each other. They each use different colors and shapes to help identify them. The charts are also interactive, so you should be able to turn each line on/off and zoom in and out...
