Um Projecto meu, revisitado, mais um Kit de Robótica, Rob Ives e Genebra, e uma Forja a Carvão

Eis senão quando, as vendas insesperadas deste meu Priojecto, pela Ponoko, me obrigaram a revisitá-lo, juntando-lhe umas Instrucções decentes...

Claro que se há uma mania comum a todos os Inventores, é a de que basta uma Imagem para se compreender todo o Conceito... Não!

Por isso, cá vão mais duas, que não só mostram para o que é que isto serve, como mostram como montar as peças:

 

3D Styro cutter Buy files now › USD $ 10.00 

A Styro Cutter with a twist...

360º of it! :D
It cuts 12 facets from 12 parallel views around a 3d Object, then it's up to you to sand out the faceted edges.
Got the idea from here:

Sim, podem pegar na jigajoga, e reproduzir uma data de Objectos sem grande esforço, em Esferovite, ou Isopor, ou Styrofoam, bastando apenas juntar-lhe uma cortadora de Fio Quente, e 12 vistas em perfil dum Objecto, que transformam em Bitolas, como se explica tão bem aqui neste Instructable, onde me inspirei para a minha Versão topo-de-mesa...

A Mindsets volta a oferecer um Kit valioso, um Robot Programável, com tudo já lá dentro,e desvia-se de obstáculos:

PROGRAMMABLE ROBOT (I.Q. ROBOT KIT)

The I.Q. Robot uses the IQ4 programmable controller which requires no computer to setup.

It is all on-board. 

The controller controls two gearboxes which can move the vehicle forwards, backwards, turn left, turn right, turn on the spot.
There is also a touch sensor on the front so that the vehicle can respond and move away from obstacles. The structure is all lasercut acrylic with carbon fibre effect wheels and rubber tyres.

Mais um fascinante Mecanismo, desta vez a Roda de Genebra, para vocês montarem em papel, obra do nosso amigo Rob Ives:

Geneva / Crank Mechanism

An interesting mechanism for you to download and make. The main handle links to a four-step geneva drive. The movement from this is an intermittent quarter turn rotation which is connected directly to a crank.

The result is this curious motion which can be used as the starting point for your own character based paper animations or made simply as a mechanical curiosity.

 ...E para finalizar, uma pequena Forja a Carvão, que podem fazer por quase nada, e em pouco tempo, perfeita para projectos ocasionais, que não justificam grandes gastos:

Make a Small Blacksmith's Forge 

Vendigroth

 

I WANTED to use a wheel from a car to do this but i couldn't be bothered going all the way to a place to get it only to carry it home and eventually set it on fire, so i looked closer to home. I ended up using a 12 inch stainless steel cake tin. I never once thought i'd be making a forge in something that vould have been used to hold cakes but it worked really well.
The first thing we need to consider when building a forge is the ariflow. Too much and it gets far too hot. Not enough and it doesn't burn at all. To get the air into the forge, we need a hole through which we can out a pipe. Wheels come with ready-made holes. Cake tins do not. Ergo, i had to make one. "It's only thin steel, what can possibly go wrong?"
I spent something like 40 minutes getting a hole big enough to put the pipe through. SO: this step's instructions: Through Fair means or Foul, Make a hole big enough to fit the pipe through. Make sure the pipe doesn't go too far in or not far enough in. about 1.5 inches was right for me.
