Um Instructable meu! E a Revista Designpark, um Mini CNC Laser, E CAD para o Couro

Ao tempo que eu não fazia um Instructable!

Mas achei que esta Dica poderá se Útil, porque é uma ideia que parece óbvia...

Depois de alguém a ter!

Resumindo, para esticarem Tubo de Latex, usem Buchas das de enfiar parafusos na parede.

Como há gente que não anda nisto das Engenhocas, é um Instructable elaborado, mas mal tenham compreendido...

MÃOS À OBRA!

Easy Rubber Tube Stretchers 

Edgar

The simplest way to stretch Rubber Tubes I know,  just add simple Plastic Wall Plugs, and some kind of thread!
Works with the plug's screws, too, of course.
Can be used for Slingshots, or any other Project using Rubber Tubes, as spring substitutes. Might also be good for Plastic and Silicone Tubes, for other uses, if there's a tight fit.
While some may just look at the first Photo and get the idea, others may not, so I've elaborated on the subject. Feel free to skip any Steps, and get to do it, if you do get it.

So here's what you need:

-Wall Plugs, 2 per Rubber;
-Rubber Tubes, of course;
-1mm Nylon rope, or other strong chords;
-And an X-acto knife, or as in this case, any Pocket Knife

Na E-Revista da Designspark, podem ver o novo Beagleboard, e muito mais, vão ao Link, e descarregem, está em 6 Línguas:

Back in Black…
Better, Faster, Stronger… 

While the Raspberry Pi has stolen many of the headlines over the past year or so for entry-level open-source embedded development boards, there have also been one or two other notable launches this year, and certainly one of these is the latest BeagleBone board: the BeagleBone Black

Eis uma pequena maravilha, e olhem que há para aí Engenhocas, Desempregados, e pequenos Artesãos que poderiam fazer muita coisa com isto...

E tem um aspecto tão impecável, que dá vontade de fazer, só por isso!

 

The MicroSlice | A tiny Arduino laser cutter

SilverJimny

A few years ago I saw an Instructable where Groover had used a pair of DVD-RW drives to make a pocket laser engraver. Inspired by the idea, driven by the recent purchase of a full-sized 50 watt CO2 laser cutter, and roused by the launch of the Microcontroller contest I took the decision to have a crack at making my own mini laser engraver.

E acho que já postei isto, mas como é impecável para a Indústria do Couro que floresce nos nossos Países, cá vai, outra vez, CAD para as vossas Criações em Couro:

Creativity in CAD: Free software supports leather venture

Bernhard Kreuzer is a leather goods designer, applying his mechanical engineering skills to turn a hobby into a new business venture – supported by MEDUSA4 Personal and the eSERVICES portal for commercial users.

Cambridge, UK and Pittsford, NY – October 2013: Bernard Kreuzer, former army captain and leather goods designer, studied mechanical engineering. He discovered CAD Schroer’s free mechanical design software, MEDUSA4 Personal, about two years ago. Today he uses it to design unique leather goods, with patents pending.
