Thanks for sharing! Maybe I'm missing it, but I don't see the Security Director role listed on the careers page? I do see an Eng Director role listed under the R&D: Security section, however. Uncertain which is which. Thanks a

Hey everyone! I wrote an in-depth article about a project I've been working on -- the Open Trickler! In this article, I describe how I built it, how it works, and how you can build your own for under $60! The project is open-sourced an

Hey folks, This is an article I've been meaning to write for years. I finally found the time to do it and am happy with how it turned out. Enjoy!

Hey everyone! I wrote a quick article to give an update on the incredible progress that's been made to the DIY accelerometer project I shared before[1]. Most notably, it's nearly six times faster! This project is fully open-source

Hey, thanks for looking!

Fair enough! I don't have the budget for a machine pistol, but maybe someone who does can try that idea out.

Hi! I see a lot of "you could" in your reply, but I'd like to point out that I released this as an open-source DIY project so that anyone could do whatever tests they wanted. I encourage you to build your own -- I'd lo

Nice! I have that board as well, but only played with it briefly. Do you have any data from your use of it on the pistol that you'd like to share? I've love to see how it turned out.

Thanks for the feedback! The Feather board I'm using actually has Bluetooth, but I have not explored using it yet. If it's faster to send data over BLE to an app, then that would make this project even more affordable and smaller

by wizdumb 8y ago
You definitely could! I chose not to simply because I wanted to make it smaller. The Feather boards are a bit smaller than the Pi Zero.

Based on the feedback from my previous experiment[1], I wrote an in-depth article about the accelerometer unit I built. In this article, I describe how I built it, how it works, and how you can build your own for under $50! The project is

I believe I provided both imperial and metric units for every equation. Maybe I missed one? I'd be happy to correct it if you can point me to the specific instance!

Thank you! Yes, as merlincorey correctly mentioned, they're called "violin plots".

[shameless plug] I hope I can convince you to subscribe for when I tackle this topic in a future article! ;)

Thanks for the question! Keep in mind that a huge explosion (with 40,000 PSI) is happening inside the chamber of the gun. Some of that energy pushes the bullet forward and the rest pushes the gun backward. You're right though, the gase

Thanks for the feedback! I've heard this suggestion a few times, and it is an interesting thought. I believe that the calculations I did which show that the bullet has left long before the rifle moves under recoil contradicts this. Tha

Thank you! As I mentioned in the Next Steps section of the article, measuring the effects of bullet sorting by weight & length is definitely a topic for a future article.

There are several physics equations (some I linked to in the article) which discuss this topic. One of the main takeaways I learned from running this experiment and doing some of the math was that my rifle is 900x heavier than the bullet, w

I shoot with it all the time and haven't noticed any variation because of it (though I admit I have not tested this directly). FWIW, I was able to earn my F-Class Mid-Range High Master classification while using it.

Great feedback! It's definitely true that I need to do some more research on this particular aspect. My trigger is set to 1 pound before it breaks (some folks set theirs to 2 oz!) Pulling it gently, like you're supposed to, should

Thank you for reading it and sharing your thoughts! I'm just here to learn and share. Hopefully this will help towards breaking down some negative stereotypes about a fun an interesting hobby!

Thank you! Funny story: I built the accelerometer with the original intent to see if I could correlate "bad" shots during 600 yard matches to flinching. That's still a work in progress, but because I had it working I was able
