Survey to help make better homemade water guns

24 October 2015 - 01:41 PM


As some of you all are aware, I also run a water gun website known for homemade designs. We're running a survey to get a better idea of what sorts of tools people have, what sort of water guns they want to build, what sort of parts they can buy, etc., so that we can make better designs and build guides. Please take the survey if you have the opportunity.

Engineering Stack Exchange

24 December 2014 - 10:05 AM

There's a proposal for an Engineering Stack Exchange website. I'm a big fan of Q&A websites in general, and I'd really like to see this get off the ground. There are quite a few engineers on this site. If anyone reading this could commit to using the site, I would be very appreciative.

Stock dart diameters

05 April 2014 - 09:29 AM

Lately I've been compiling data about darts. One thing I've found to be lacking is the available data about stock dart diameters. There basically is none, and for the moment I have no access to Nerf guns or darts to make my own measurements. Would someone with calipers mind measuring the diameter of the heads of their stock darts? Post that along with the dart type. Foam diameter and other dimensions would be interesting too, but I'm most interested in the head diameter. This'll be useful for an upcoming dart safety article, and I'll be appreciative otherwise.

To be more specific, if you look at whistlers, for example, you'll see that the head is bigger than the foam. For streamlines, the opposite is true; the minimum diameter of the head is smaller than the foam. This is the diameter I'm most interested in.

Be on the lookout for broken pages

I've made a few security changes to the site that might break some pages, mainly on the wiki. Post here if you notice anything out of the ordinary anywhere on NerfHaven.

Welcome to Nerf Engineering

25 February 2014 - 09:57 PM

btrettel's Nerf blog was my blog about engineering Nerf guns. There I discussed various aspects of Nerf gun design with a particular focus on theoretical and experimental analysis. The goal was better Nerf guns.

Now it's a column titled Nerf Engineering in the articles section here at NerfHaven. The focus and goal are the same, but the audience is much larger. Despite that, I will make no attempt to dumb down the content. I write for someone in college or older. Some background in calculus will be required for some posts.

Expect a post every week or two. I have a large backlog of topics I've already analyzed, but have not written about in usable form. You can post requests here, in this thread, for now.

All posts here will potentially be updated after their original posting. The date of last update will be listed at the bottom of the post.
