LOW COST DIY 500€ CNC MILL
Vulcaman

Hi,
in this Instructable I want to show you, how you can build your own CNC-Mill for less then 500€. I designed this machine for CNC-beginners, who don't want to spend a lot of money for their first experiences with CNC machines but also expecting a rigid and professional looking CNC.
This machine is perfect for maker, tinkerer and everyone who wants to start CNC-Machining.
In the pricerange of sub 500€ you will not find any other CNC with these features:

•  710 Watt spindle motor
•  MGN linear-rails on all axis
•  1204 ballscrews on all axis
•  effective workarea of 250x220mm
•  max. travelspeed of 3000mm/min (at 12V)
•  high accuracy of 0.1mm in all axis
•  super rigidportal frame (out of one piece of wood and aluminium extrusions)

Algo de muito útil, a lista dos tópicos dos fantásticos Vídeos de Dan Gelbart, um Génio da construcção de Protótipos, e penso TODOS os Engenhocas deviam ver os seus vídeos, para evitarem muita dor-de-cabeça, e fazerem muitas mais coisas do que pensam possíveis, com os meios de que dispôem:

Dan Gelbart : How to Build Stuff

Al-Hala

Dan Gelbart has an excellent and well-presented series on YouTube on machines and prototyping. It`s a short course on how to build stuff aimed at students, researchers and others who are not machinists by trade. It`s applicable to prototyping and limited production with enabling technology in 18 parts, which I’ve listed links to below. Note: the chapters were obviously shot out of sequence, as there is referral to `as we`ve seen before` when we have not. It`s not that bothersome.

Para o bem dos vossos pés, têem agora este Site onde podem desenhar solas para os vossoa sapatos, para imprimirem em Filamento flexível, e até, solas correctoras de defeitos!

What is Gensole?

Gensole is a browser based tool which allows you to design insoles, optimised for 3D printing using the FDM process and Filaflex (TPE/TPU) type materials. It will ultimately export .AMF files for importing into Slic3r for 3D printer toolpath creation.
It is free for makers, and researchers for non-commercial use :

...E acabamos, por hoje, com este Instructable para os que precisam de uma série de Baterias de Lítio para toda a espécie de Enhenhocas!

How to Make a 18650 Li-ion Battery Pack!

Nematic!

18650 Li-ion cells are a great way to power Projects. Which provides a nominal voltage of 3.7V which is not sufficient for most of the application for let's say you want to power a BLDC motor with an ESC which requires 9V to start. So we need more voltage which can be achieved by connecting them in series. So in this tutorial, I will show you how you can make a 18650 Li-ion Battery Pack with a BMS circuit and all the things you need to know before you built one!
