3D printing chocolate has been a distant dream for ages, but finally the future is here. No but really, it’s a neat concept. It works by a stepper motorrotating 2 gears that generates pressure to move the liquid chocolate down through a nozzle. You place a bunch of chocolate inside the tank and let it melt by a heating element connected to the hotend of the 3D printer.
Listening to Astronauts ON THE ISS with a Baofeng UV-5R

Alienware Concept UFO is a Switch killer that plays PC games
The quest to play demanding AAA games on the go sans gaming laptop has long been a dream of PC makers. And the Alienware Concept UFO realizes that dream in spectacular fashion.
There have been a few promising attempts in the past, but nothing feasible or compelling enough to take off with mainstream gamers. Alienware has created a device so tantalizing, the company has done something it’s never done before –– show off a concept product to the public.
Alienware’s latest venture takes familiar concepts (like the Nintendo Switch) and builds on them to forge what could very will be the future of mobile PC gaming.
Build your own tracking and GoTo mount for DSLR astrophotography
Astrophotography can be challenging, in a large part because your subject matter — or your base, the Earth rather — is constantly moving. In order to take excellent long exposures of far-off objects, Redditor intercipere came up with a beautiful 3D-printable, star-following mount that holds and rotates a DSLR camera.
Now intercipere can simply input the RA/DEC coordinates and the device will automatically move to a desired target in the sky.
PERFECTLY sharp knifes! 3D PRINTED sharpening tool
3D print yourself a tool to perfectly sharpen your knifes! 3 years ago my first intention with this channel was to make tech and science content but also geeky cooking videos. Well, due to time constraints I ended up only doing the first besides some sous vide cooking on live streams. In order to go back to the roots at least a little, we’ll today explore my most popular Thingiverse model, the DIY knife sharpening tool for perfectly sharp blades.
