Most CNC robots people see involve belts and rails, gantries, lead screws, linear bearings, and so forth. Those components need a rigid chassis to support them and to keep them from wobbling during fabrication and adding imperfections to the design. As a result, the scale is necessarily small — hobbyist bots max out at cabinet-sized, for the most part. Their rigid axes are often laid out at Cartesian right angles.
One of the exceptions to this common configuration is the delta robot. Deltas might be the flashiest of CNC robots, moving the end effector on three arms that move to …read more http://pje.fyi/PwlWqp
Nintendo’s latest Zelda-playing device, the Switch, is having no problems essentially printing money for the Japanese gaming juggernaut. Its novel design that bridges the gap between portable and home console by essentially being both at the same time has clearly struck a chord with the modern gamer, and even 8 months after its release, stores are still reporting issues getting enough of the machines to meet demand.
But for our money, we’d rather have the Raspberry Pi powered version that [Tim Lindquist] slaved over for his summer project. Every part of the finished device (which he refers to as …read more http://pje.fyi/PwjgBR
With the wealth of Nixie projects out there, there are points at which Hackaday is at risk of becoming Nixieaday. Nixie clocks, Nixie calculators, Nixie weather stations, and Nixie power meters have all graced our pages. And with good reason – Nixie tubes have a great retro look, and the skills needed to build a driver are a cut above calculating the right value for a series resistor for an LED display.
But not everyone loved Nixies back in the day, and some manufacturers did their best to unseat the venerable cold cathode tubes. [Fran Blanche] came across one of …read more http://pje.fyi/PwfD12
