This didn't take too long to build, but it was fun and unique. Tensegrity is a structural technique that relies on elements under tension for its integrity (hence the name). Tensegrity structures also have elements under compression, but their discontinuous arrangement gives a gravity-defying appearance to the whole.
Despite the same word appearing in both titles, this post is quite different from the previous one [https://danbscott.ghost.io/open-channel-hydraulics-for-paddlers/]. The inspiration for making the project described in this post came partly from re-reading Anathem [https://danbscott.ghost.io/neal-stephensons-writing/] last year [https://danbscott.ghost.io/2018-year-in-review/].

This post is about a DIY project I just did to get carbonated water at home, without getting a Sodastream. I mostly followed the project description from this article [http://www.seriouseats.com/2014/06/pros-cons-diy-carbonation-rig-how-to-carbonate-cocktails-at-home-equipment-how-to-build-cheaper-sodastream-replacement.html] , with a few small changes. Mainly, I got my CO2 cylinder from a
This post is about one of the DIY projects hinted at in my previous post [https://danbscott.ghost.io/my-latest-3d-printing/]: an indoor air quality filter. Activated carbon can adsorb volatile compounds (such as odours)—see the discussion here [http://diy.stackexchange.com/questions/8512/can-activated-carbon-eliminate-odors-in-a-bedroom] . I wanted to rig up
This is a discussion on the economics of 3D-printing based on printing the bookend [http://www.thingiverse.com/thing:417703] from my last post [https://danbscott.ghost.io/new-bookshelf/]. As shown below, this part (including auto-generated scaffolding) was approximately 100 grams. The print time was approximately 4.5 hours (plus
