Btrettel's Nerf blog. Random thoughts about the ballistics of foam darts. I am developing a Nerf gun purely for test purposes. My main goal is to get consistent performance. I am using a few methods to do this: regulated pressure, reducing the effect of the speed of opening the trigger valve by piloting my QEV with another smaller QEV (that is in turn piloted by a smaller trigger valve), and using stiff aluminum barrel to reduce the effect of barrel vibrations. Or does the speed cause other effects?

Btrettel's Nerf blog. Random thoughts about the ballistics of foam darts. Goals for the end of 2011. I’ve been too busy to accomplish what I want to in this hobby, but I do have a few plans for the end of this year:. I will write a NerfHaven article about misconceptions in Nerf physics. I have already written a few things along these lines. The goal here is to make a summary of many misconceptions. I will buy a drill press, a vise, and some other tools so that I will have my own machine shop. Lately, no&...

Btrettel's Nerf blog. Random thoughts about the ballistics of foam darts. I’m not entering Ryan’s contest. To answer a question that I’m sure will be asked, I will not be entering Ryan’s contest. I do not have easy access to anything resembling a machine shop or much money to buy components with. This is unfortunate. I have, however, explained my ideas elsewhere. Others are free to implement these ideas as they please. July 2, 2011 at 6:53 pm. Or leave a trackback: Trackback URL.

Btrettel's Nerf blog. Random thoughts about the ballistics of foam darts. NY Times Magazine Interview. I was interviewed for the New York Times Magazine. About my other toy gun hobby: homemade water guns. I haven’t worked on homemade water guns for several years now, but I’ll eventually get back into the hobby. Edit: To be clear, I am not Lonnie Johnson. He was interviewed first in the article. The section with me is at the end. August 7, 2013 at 10:01 pm. Or leave a trackback: Trackback URL.

Btrettel's Nerf blog. Random thoughts about the ballistics of foam darts. I’ve started organizing my writings and thoughts on Nerf ballistics into a set of notes. Link corrected). Readers of my blog might be interested. For the moment my notes are very rough and incomplete. I’ll update the PDF as I make changes. I’d appreciate any feedback, especially corrections and ideas. Edit (2012-10-02): I’ve removed the notes because they need a lot of work before I’m comfortable distributing them.
