EASY build Vacuum Casting machine system for Lost Wax / PLA Casting - DIY chamber & Pump : lwc #6
VegOilGuy
Vacuum casting machines are expensive. But can you make one? YES… here’s a easy, simple construction, low cost vacuum arrangement to assist with you lost wax or lost PLA casting. Many of the parts you may already have lying around and the rest are cheap as chips. Building a vacuum system has literally saved me thousands and just as importantly it’s dramatically improved the quality of my metal castings… beautiful, clear and precise details matching exactly the original wax pattern, with no pockets, no porosity and no sand. This really is a cheap and simple solution to better lost wax casting!

Só coisas boas!
Agora é esta pequena maravilha de Fresa CNC, da qual, que podem Imprimir muitas das partes!
Toca a fazer uma, e mais nada!
DIY 3D Printed Dremel CNCNikusWhen I got my first 3D printer I was extremely happy with all the new possibilities to create things but after some time I noticed the limitations of 3D printing. Plastic is easy to melt, sometimes it's not mechanically resistant enough and most importantly sometimes doesn't look good. Don't take me wrong here, I love 3D printing and I like plastic (except plastic waste) but there are things that look, work or feel way better when made out of nonplastic material. Imagine all your furniture made out of plastic. Sometimes I prefer wood, when I need strength, metal (mostly aluminum) is a way to go. That's where CNC milling machines are used. Usually, the cost of such machine is really high, most of the hobbyist, small makers can't afford such expensive equipment. That's why the idea of building my own CNC machine sparked in my head.
E terminamos por hoje, com esta ideia Estratosférica, atenção, malta das Universidades, como fazerem os vossos próprios Balões Estratosféricos, para o bem da CIÊNCIA!
MUÁHÁHÁHÁHÁHÁ!
How to Make a PicoballoonJakub_NagyWhat is a picoballoon and why would I want to build it?! I hear you ask. Let me explain. You all probably know what a HAB (High Altitude Balloon) is. It's a bunch of weird electronics stuff connected to a balloon. There are soooo many tutorials regarding HABs here on Instructables.
BUT, and that's a very big BUT what they don't tell you most times in the tutorial is the cost of the filling gas. Now, you can build a decent HAB tracker under 50€, but if it weighs 200g (which is a pretty optimistic guess with the batteries, cameras, etc.) the helium to fill the balloon can cost you 200€ or more, which is just too much for many makers like me.
So, as you can guess, picoballoons solve this problem by just not being bulky and heavy. Picoballoon is just a word for a light HAB. Light, what do I mean by light? In general, picoballoons are lighter than 20g. Now, just imagine that a processor, transmitter, a PCB, GPS, antennas, a solar panel and also a battery with a mass same as a disposable coffee cup or a spoon. Isn't that just insane?
