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 again!

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 and it uses off-the-shelf components. The controller was written with NodeJS and the mobile app with Flutter.
I hope that this content is high quality enough to justify the time you spend reading it, and how much time it took me to create it!
I’d love to hear your feedback and answer any questions!

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[2] and I have no plans to sell it complete or even as a kit. Keeping it open allows contributors from all different backgrounds, which led to the improvements I describe here.
I'd love to hear your feedback and answer any questions!

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 love to see what you can make and learn with it!

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 because the SD card and RTC are no longer required.
I believe the Feather M0 board I'm using is also capable of running CircuitPython (fork of MicroPython). For this project, I wanted to keep it simple, so I opted for Arduino, though I am more familiar with Python.
If you have any specific advice or improvements you'd like to suggest, I'd love to get them in either PRs or Issues for the project over on GitHub! https://github.com/ammolytics/projects/tree/master/accelerom...

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 open-sourced and it uses off-the-shelf components. Data analysis was done using Python, Pandas, and Plotly.
