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!

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.

Gduino-No Programmer Required!! for 5$,Programs Multiple AVRs

Gursimran Singh 425 

 Arduino is familiar to anyone who loves to build tech.It is very common in project makers.But why 25$ For this board!! We can make our own!! In this instructable I am going to show you how to build an arduino at home that doesn't need any external programmers like USBASP or serial communicators.USBASP is already embedded inside this circuit!! I was impressed by bjkayani's instructable Beeduino ,the tutorial is well detailed and also Thomas Fischl's USBASP.I decided to make both these circuits on one board.Not by soldering a perfboard or on breadboard but on our very own built PCB!! Yes we can make it at home!! I will show two ways of etching PCBs and also tell which one would be better!! The other interesting thing is that I made it in just 5$ 5 times less than that of original arduino. And also we can program many other programmable ICs like ATtiny45/85 etc.Enjoy!!

SVG Nest 

What exactly is "nesting"?

We have some (2d) parts to cut and a piece of material, we want to arrange the parts to use as little material as possible. This is a common problem if you use a laser cutter, plasma cutter, CNC machine etc.

In computer terms this is called the irregular bin-packing problem

How much does it cost?

It's free and open source. The code and implementation details are on Github

Roman UrsuHack

Gas-jet (up to 1000ºС) with your own hands!

With the turned on blowing the gas-jet has a good heating power, it can set alight a plumbeous pellet in a few seconds (up to 1000ºС)!

In conclusion I'd like to say: this gas-jet may be improved by installing an ergonomical (pistol) handle and add the piezoelectric element for lighters for the facilitation of firing.

using Inkscape and Gcodetools for CNC plasma cutting

Mr. Hay's Technology

I like SheetCam for generating G-code for a CNC plasma cutter from DXF or SVG drawings, but I prefer free and/or open source programs that students can use on their own computers. Inkscape and the Gcodetools plug-in achieve that.

Version 0.49 of Inkscape will include Gcodetools, but until then we have to extract the contents of the Gcodetools download (using a program such as 7-zip) and put them in the appropriate Inkscape directory (probably c:\Program Files\Inkscape\share\extensions\ on Windows).

Engineering A 3 Wheel Vehicle Chassis

MechEngineerMike  

My university senior project was extremely ambitious. Over the course of a year (2011), myself and three other mechanical engineering students designed and fabricated a complete solar race car chassis including the frame, suspension, hubs, spindles, brakes, & steering.

Its been almost 5 years now but vehicle design is just as fascinating to me today. In retrospect any one of the above systems would have been an adequate senior design project. My decision to attempt all of them together reveals the ignorance/arrogance/ambition of my younger self. In the end we were successful though and I learned a heck of a lot about chassis design. I'm sure there are a few more ambitious university students out there who could benefit from my experiences.

This instructable will discuss the engineering process of designing a custom 3 wheel vehicle chassis. The project consisted of research on vehicle dynamics theory and calculations, 3D modelling, structural stress analysis, designing around human factors, component sourcing, and lots of time spent fabricating.

Worlds Smallest DIY Survival Kit

Akinventor 

I have created what I think to be the world's smallest survival kit. While this kit is certainly not the only thing you should count on, it is very useful and tightly packed. I can say for sure that at lease one of the things would help in nearly any survival situation, if not more. The tape, the thread, and the fire making kit are avery useful. I have not used this kit to do so, but I have made fires from one match and no external tinder many times. Please do not comment below telling me how I will die in the wilderness, I am from Alaska and I always carry more than just this one kit.

Here is what the kit includes:

Fish Hook

Needle

3 feet of cord

Two Matches and striker

Fire tinder

Knife

Compass needle for DIY compass

1 foot of electrical tape

These things can be used with the combination of the outdoors to equal:

Food

Shelter

Repair

Fix a car bumper dent with some easy DIY

Allison Blackburn

If you have ever had a dent on your car bumper you will know how maddening it is, more so if it wasn’t your own fault. It’s bad enough if you prang the bumper but if you park in what you think is a safe spot and then return to the car to find your bumper messed up, it’s annoying to say the least. In some cases the dent may not be as bad as it first looks, however it looks unsightly and you will want to get it fixed. The downside is that taking it to a mechanic will cost you a pretty penny and of course it can take time to get the car booked in, meanwhile you have to drive around in a car with a crunched bumper. Well not anymore as you can fix a car bumper dent with easy DIY.

Open-source DIY Tabby car can be constructed in 60 minutes

Bridget Borgobello

Italian open source enthusiasts Francisco Liu and Ampelio Macchi have teamed up to design the Tabby DIY car. In recent years we've seen a popular surge in open source furniture models, tricycles and even housing designs, but a build-it-yourself two to four passenger vehicle with a chassis that can be assembled in less than 60 minutes is pretty exciting stuff.
The OSVehicle project was launched late last year and aims to open the door to a new platform where an economic and road legal vehicle can be built by smaller organizations, or even by individuals who are happy to get their hands dirty. The OSVehicle open source platform has set itself up to create an "IKEA"-type of car, giving folks the basic design and mathematics to construct and complete their very own passenger vehicle.

CNCKing.com: My video inspirations growing-up

Well, it has taken two years and the final finishing touches are now being made on my 4th design book (7th overall) CNCKing.com: Rise of the CNC and I’m very excited at the potential it has in the market place. It has taken me 5 years to get to this point and time has really gone so fast… I’m having it checked over by another editor with a fine tooth comb before releasing the digital PDF version first followed by the printed on-demand version a few weeks down the road.

Now that the book is essentially out of my hands, it’s nice to reflect on how much I’ve learned and processed through the years – there is yet so much to be made and so many directions I can take CNCKing.com. Looking at Ben Heck’s videos (who wrote the foreword to my book) I see I have a tremendous amount of growth to make in the video component of my site – I’ve finally gotten over my “video fright” and instead of having to make hundreds of takes because I kept forgetting what I was going to say or memorized as soon as the “record” button was activated, I can do it now pretty much in only a few.

Flexible Glow in the Dark Sheet

This vinyl sheet is thin and stretchy with a smooth, satin finish. It can be cut with scissors, die cut or sewn. It’s ideal for use in apparel and costumes, as well as any project that requires a stunning glow. The material is eco-friendly, nontoxic and machine-washable.
You can charge and re-charge the sheet in UV light (natural daylight, lamp or black light) in 5-30 minutes, and the glow will last for 8+ hours until fully recharged again.
This photoluminescent sheet features a proprietary technology for superior performance. It works at the molecular level to absorb the energy of UV light through exposure to sun, lamplight or black lights. When light is removed, the absorbed energy is emitted as a glowing light. The brightness of glow is dependent on color selected, dimension of material used, and darkness of surroundings. It is either charging or emitting light, depending on the presence of another light source.
This material is currently only available in Lime. Other colors are coming soon.
