While they don’t give the physical thrill of a real one, model roller coasters are always fun to watch. However, they actually make a poor analog of a full-sized ride, as gravitational force and aerodynamic drag don’t scale down in the same way, model roller coasters normally step way faster than the same design would […]

often it begins to feel like a tradition that a certain substance or group of substances become highly popular due to certain highly desirable chemical or physical properties, only for these chemicals then to go on to turn out to form a hazard to the biosphere, human life, or both. In the case of per- […]

steam turbines are at the heart of all manner of industrial machinery, particularly that used for power generation. [Integza] decided he needed to better understand this technology, and decided to build one himself – using 3D printing, at that.  First, a steam source was needed, with a pressure cooker on an electric stove pressed into […]

There’s just something so pleasing about scaled-down electronic replicas, and this adorable 3D printed pedestrian crossing light by [sjm4306] is no exception. Although a little smaller than its real-world counterpart, the bright yellow housing and illuminated indicators on this pedestrian lamp are quickly recognizable due to their ubiquitous use throughout the United States. The handful […]

[Lucas VRTech] has made some significant progress with building force-feedback type haptic gloves for use with steam VR games. The idea is pretty straightforward: the end of the finger is attached to a cable, which is pulled from inside a sprung-loaded spool; the kind used for hanging ID cards on. The spool body can rotate, […]

Typically, to enhance one’s eyesight, we look to tools like corrective lenses or laser eye surgical treatment to enhance optical performance. However, [Casey Connor 2] came across one more method, that utilizes light exposure to enhance color vision, as well as set about trying to accomplish the exact same results at home.  A recent research […]
