Este Instructable é para uma pequena Casa, no Quintal, ou no Terraço, mas pode-se engenhocar, e fazer dessa casa uma Oficina, para poderem finalmente fazer o que quizerem!
Ou uma Casa-Oficina!
É bom.

Tiny House Series: Pt. 1 ExteriorTrask River Productions  

We at Trask River Productions are building a tiny house! We had great success with our tear drop trailer last year, so this year, we stepped things up a bit and started a tiny house. Due to the enormous task of building a tiny house, we are going to break our instructable down to 3 separate steps;
1) Exterior
2) Interior
3) Furnishing/Finishing Touches
This instructable is the first step of the process, the exterior. Subscribe for automatic updates when we post the next part of our Tiny House Series.

A Carpintaria torna-se mais fácil, com um bom Torno, como este, que podem fazer, para terem um Torno versátil, mas forte, como deve de ser:

Make It - Moxon Vise

dpmakestuff  

I decided to finally add a proper woodworking vise to my arsenal of tools. I choose a Moxon Vise for it versatility and relatively low cost. I picked up a kit for this vise from Benchcrafted and for what you get, the price was acceptable. The downside to living in Canada is that sometimes tracking down hardware at a reasonable price can be challenging. There are other options available to you if you'd like to save a few dollars and don't mind digging around online.

Para aprenderem a meter as Mudanças, e em geral, a conduzir, podem fazê-lo em casa, e poupar em tempo e dinheiro!

Depois, é só arranjarem um Simulador de Condução...

Car Simulator Arduino Pedalsjensws  

I have a on going project to build a car-simulator and one goal is to get the feeling like sitting in a real racing-car. With this instruction I explain how I have build my pedals to my car simulator. Of course you can buy stuff like this but I want to build it cheap. My pedals have gas, brake and clutch and use a Arduino (Windows native drivers) to connect to usb port.
Hope I can inspire you with my building and I meet you on a trackday in Project Cars!

Maravilha.

World First! DIY Real 4k (UHD) Beam Projector

bumhee34 

Hi all.

I want to share my newest build: A DIY "real 4k" Beamer.

The original post is in my Korean blog : go to my Korean blog, and

in my English blog : go to my English blog

Here, the 4k means "3840x2160" resolution (called 2160p) upto 60Hz.

Why did I make this little 4k beamer?

In the current market, commercial "real 4k" beamers are only made by Sony, and the price starts at 9,999 USD except the discontinued models. The another type of 4k beamer uses so called "e-shift" technology, but it is not physically 4k. Anyway, the 4k beamers are way tooo expensive for me.

Want to watch Neflix in 4k resolution!!

I haven't used my DIY 2k beamer, but used my DIY FHD beamer due to several issues; it has poor brightness, the only media source is PC, and 2k resolution is not commonly used. Sorry to guys who followed my 2k builds so far!

I like to build something new by myself.

SO? I've started this little project.

To save your money, I've done many experiments (tests) instead of you guys.

You can make this 4k beamer rather easily using my AutoCAD drawing files and this instruction.

I hope this instruction may be helpful to someone wants to have a 4k beamer.
