    Project: Inexpensive Rifle Accelerometer

    Thanks for taking the time to read it, I really appreciate it! It can definitely be used while dry-firing -- I actually did that to determine that the firing pin was the cause of the forward acceleration (towards the muzzle)! Great suggestions for other use-cases. I'll have to see if I can get...

    Project: Inexpensive Rifle Accelerometer

    The good news is that there's a HUGE variety of options available these days, making it very easy to solve most problems. The bad news is that it can take quite a bit of research and experimentation to determine which components work best. I had good results working with the LIS3DH...

    Project: Inexpensive Rifle Accelerometer

    I did! There were three reasons why I choose the Feather board: 1. It was a bit smaller (2"x0.9"x0.28" VS 2.6"x1.2"x0.2") 2. I already had one on hand 3. There were more stackable wing/shield options that fit my needs at the time That said, the Pi Zero is a totally feasible platform for...

    Project: Inexpensive Rifle Accelerometer

    Thanks for taking the time to read it! I don't have a ton of experience building electronics either, which is why I worked with off-the-shelf components that are more plug-and-play. It really wasn't very hard and I think my instructions should provide enough detail that anyone can put one...

    Project: Inexpensive Rifle Accelerometer

    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 SnipersHide. https://blog.ammolytics.com/2019-01-01/project-cheap-rifle-accelerometer.html In this article, I describe how I built it...

    Range Report Recoil vs Muzzle Velocity

    Thanks for the heads-up. Do you know if that material is available anywhere outside of that paid-subscription forum?

    Range Report Recoil vs Muzzle Velocity

    I see what you mean now, thanks for clarifying. I can only share my own anecdotal data here -- I haven't seen this issue on my rifle. At my range, I have to zero at 100yd off of a slippery concrete bench without the 2x4 rig pictured in my article. I would expect a significant POI shift to mess...

    Range Report Recoil vs Muzzle Velocity

    Hey folks, author of the article here. Thanks for sharing and taking the time to read my work! I'm here to answer some of your questions. That's interesting that they would see POI shifts. It makes me wonder if they are stressing the rifle stock and action, or if the barrels weren't properly...
