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.

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.

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.

Rocket Boat

makjosher 

Every year in October, some friends of my parents have gotten together at a cabin next to a small pond. As a kid it was one of my favorite times of the year, as it meant I got to hang out with my two favorite cousins and one other friend. One year we got the idea to build a simple wooded boat and attach some model rocket engines to it. We built the boat and launched it from the dock. That boat only went about 6 feet, but an annual tradition was born. Over the next few years we built several more boats - most were dismal failures. Eventually, my brother decided to have a go at building a boat and his boats were considerably more successful. We gradually increased the rocket thrust and even added a second rocket stage. Our most successful run made it around half way down the pond before the boat lifted off the water and tumbled out of control. This year I decided to build my first boat in quite some time - this is the story of that boat.

Smartphone Controlled Cat Laser

Ikkalebob 

I've been wanting to start exploring the world of microcontrollers and programming for some time now, so I came up with this simple project which uses an app called "Blynk" to allow you to wirelessly control an Arduino board through your wifi. Now obviously the end result isn't the most practical device you'll ever build, but this was a great way for me to learn the fundamentals of programming Arduino and it can help you to learn too.

I've tried to arrange this project in an easy-to-follow format so it's ideal for someone who knows nothing about Arduino, but there's a lot of room for tweaking and improvement in my code that would allow more advanced users to get some use out of this project too.

This is a project that's been done before a few times, but I wanted to add something new by giving the system remote control functionality.

DIY Magnetic Hand-Saw Guide - Extremely Accurate Cuts!

Yonatan24 

I think handsaws are WAY better than circular saws for many reasons, but I always come across one problem: I'm never able to saw perpendicular, aka square, at a 90° angle. You can see the example for this here.

I have (finally!) received the saw that I won back in the 2015 Shelving Contest with my Ultimate Magnetic Pegboard. It's extremely sharp, beautifully made, and has a really comfortable handle. However, it is very thin, and doesn't have any aligning support on the top, so it bends really easily while sawing.

A well known solution for this is a Miter-Box. I've bought one, but it just doesn't work. Instead of having the sides hold the saw, I just saw into the plastic...

One day I was daydreaming a bit: "If I take that magnetic dovetail jig that I saw in one of Jay Bates' videos, and align it differently, will I be able to use it for sawing at 90°, perpendicular, and square to the wooden board that I'm sawing?" So I do a quick search and: "Wait, WHAT? It costs 50 DOLLARS?"

"OK, nevermind. I'm making my own!" I decided that I'd make myself a magnetic guide, which ensures that the cut will be square in all directions. Alternatively, you can modify it, and use it for dovetails, miters, or anything else.

Make a Router Planing Jig

WOmadeOD  

No Planer/Thicknesser, or maybe it's not wide enough? If you have a router, then this router planing jig might be right up your street.

I built mine as an improvement over what I've used in the past to plane wide planks for waterfall tables. I estimate it halves the time to get the same job done as before - not bad for something cheap, easy, and quick to build!

Let me show you how I built and use it.

CNC Drum Plotter

lingib 

This instructable describes an A4/A3 plotter made from a section of plastic pipe, two BYJ-48 stepper motors and an SG-90 servo. Essentially it is a flat-bed plotter rolled up into a drum.

One motor rotates the drum while the other moves the print-head. The servo is used to raise and lower the pen.

This plotter has a number of advantages over a traditional flatbed plotter:

significantly smaller footprint

only requires one linear guide rail

simple to construct

cheap

An on-board interpreter accepts the gcode output from Inkscape.

Communication with the plotter is via a bluetooth link.

The plotter is compatible with the CNC Graphics Tablet described in my instructable http://www.instructables.com/id/CNC-Graphics-Tablet/.

While not a precision instrument the accuracy of this plotter is satisfactory for its intended purpose of transferring watercolor outlines on to paper.

How to Make a Propane Forge

MaxPower1977  

In this Instructable I show you how to make a high efficiency propane forge. I have made a few forges so I have a good idea how they go together but I will give reference and credit to Ron Reil and his designs, that is where I learned how to build them over 12 years ago.

This forge can be used for knife making, blacksmithing, glass making or anything else you can think of that requires heating up stuff to a really hot temperature.

I have access to a welder so I was able to weld some parts together for this forge but if you don't have access or know how to weld, an option is you can braze the parts together or be creative and bolt things together.

Brass Casting - Got Nice Ingot

DuralM  

In this short article, if I can call notes about my humble experience an article :) I'd like to show how I casted 614 gram (1 lb. 5 oz.) round brass ingot. For many people who start melting and casting metals, it can be hard to melt brass, bronze, copper after for example, lead and aluminum. The main problem is high brass melting point.

That’s why I had to upgrade my blowpipe before melting and casting brass. It was a real challenge to exceed 900 °С (1652 °F).

Water Powered Flashlight (v2)

ASCAS

Batteries are too mainstream, let's make Water Powered ones! This is my newer version of my previous flashlight project, this time we are using pennies (literally)! The flashlight works by using water as its electrolytes.
Getting Some Inspiration From My Vacation:
I spent a third of my summer hopping on the pristine islands of Palawan. We wake-up early everyday (4:30am). We rented a boat for the tour and one thing that I've noticed, the boatman used a flashlight to prepare the boat every morning, same for the fishermen who wakes-up early. I stared at the sea for quite some time and I remembered, these men can power their flashlights using the saltwater around them.
Is It Really Powered By Water?
Th internet currently has beer batteries, lemon batteries, potato batteries and water batteries. All of these batteries are powered by the same thing - the Redox reaction between copper and zinc or aluminum. The fluid (or potato) is just the electrolyte, and any solution with dissolved ions - which is basically any solution in water at all - will serve as an electrolyte. Some chemists will react bad to this title, some aren't

Hi there!

At the begining I have to warn you... The solution presented below is quite inefficient and weird. There're some foolish techniques used in this project, e.g. power output stage for the motors or my own PC software. All of these were created mainly for fun and getting skills. It might be quite hard to clone it, but I decided to publish it anyway - just want to share what I made ;). Check the video above to see how my plotter works!

Repurpose an old wifi router for the internet-of-things

danasf

The popularity of internet-connected devices built with Arduino shields or single-board computers like the Raspberry Pi and Beaglebone has exploded, but for simple tasks like controlling a relay, reading a sensor, watering your garden or lighting LEDs there's an overlooked (and often free) option: old wifi routers and access points.

Used APs and routers are wasting away in our homes, offices, and landfills, and though they won't match the hardware of a Pi or Beaglebone, they do usually have a few GPIO pins, a serial port, wireless and ethernet connectivity, possibly even a USB host port or Power-over-Ethernet support!

Have you ever paid attention to striking difference in the thickness of forefingers in X11/Unix and MS Windows users, respectively? The latter have much more muscular forefingers that often suffer from chronic aches in their joints. They also much more often develop mouse arm, pain in the neck and shoulders, and other troubles known as Repetitive Stress Syndrome and associated with excessive usage of a pointing device. Why?

Building A Working Plotter Made Out Of Cardboard And Glue

Hello, world! Niklas Roy teaches students to build electronics from organic materials.

If life depended on explaining what’s going on inside of a computer at a fundamental material level, most of us would be screwed. Despite spending the majority of our daily lives using complex electronics, precious few of us have any clue what’s going on inside. Those innards are exactly what interest Berlin artist Niklas Roy. 

Roy describes himself as “an inventor of useless things,” which is a funnier way of saying “inventor of things other people will think are useless.” In fact, his work is penultimately useful: An instant camera that prints on receipt paper, for example, or a tiny sweeping robot that uses a toothbrush as a broom. Earlier this year, he rigged his Berlin doorbell with a laser gun sound and an LED calling card. His work is glitchy and low-fi in a way that some might call twee, were it not underpinned with an incredible intelligence and engineering know-how.

Sadly, widespread homelessness isn’t going away any time soon, and until society works out a larger solution, ideas are needed to improve the living conditions of people without a home right now. One such idea put forward is a cardboard-constructed pop-up shelter dubbed “Cardborigami,” which is designed to serve as a transitional shelter until a permanent home is found.

A better vacuum chamber 

Random_Canadian

If you look back upon my previous work you will find that I have been experimenting with vacuum metal deposition.
I have been attempting to vaporize metal and have it coat glass under a vacuum. There will be more on this once I get the process working flawlessly.

Ideally this is done under a very deep vacuum using a diffusion vacuum pump.
I am attempting to do this without the use of a diffusion pump.
The vacuum chamber that I have been using is showing signs of melting and burning which to say the least is less than ideal for the task at hand.

The first problem is the type of material used for the chamber base. The second is in dealing with the heat generated and the third is the vacuum seal.
I have come up with a solution to all three in the most unlikeliest of places...
