Lamp X - The Atmospheric Lamp

These qualities can be sensory, emotional, harmony, beauty, a feeling of presence and can set the mood and overall feel of a space. The experience of space and the emotions they evoke are greatly affected by light. Light surrounds us and is essential to us as human beings, whether it is artificial light coming from billboards and streetlights in bustling Times Square or the calming dappled light filtering through swaying trees in a meadow, light affects our experiences in subtle ways some might take for granted.

How to Build the Ultimate Survival Shotgun. As a Survival and Preparedness instructor, I take my line of work very serious – sometimes too serious.

How to Build the Ultimate Survival Shotgun

Occasionally, though, I like to take on survival projects that are just down right fun. This article highlights one of those projects. I’m fortunate in that I’ve been able to turn my passion into my profession – this being the study of Survival and Preparedness. I’ve always enjoyed building survival kits of all shapes and sizes. Wooden sheath for cook's knife. Inexpensive Soft Metal Bending Tool. This project may not seem extremely exciting but it is very useful and satisfying to create other parts with once it is finished.

If you are a true Maker, you are already teeming with excitement over the fact that you are reading another instructable and expanding your mind's quiver. Dry Film Solder Mask. This Instructable is about dry film solder mask, in other words, is the green stuff that is on top of the circuit board. I like to use smd components in my circuits board because I don't have a computerized drill machine and do in it by hand for a big boards are really tedious.

Soldering smd components in a copper board without dry solder mask, especially for those little capacitors and resistor of 402 in size, becomes a tough challenge and of course those micro controllers with almost zero space between pins. So I decided to use the UV curable Ink, sounded very good on those ebay stores with before and after pictures. Preventive lights for door edge. Bench Power supply. Lead / Pewter Casting at home.

Free-form curved furniture without molds / Part 1. Ever heard of Zipshape?

Free-form curved furniture without molds / Part 1

It's a technique developed by Schindler Salmeron which lets you to draw a free-form profile curve for (say) a piece of furniture, and then cut a series of teeth into two sheets of thick material like MDF. Those custom-cut teeth are very specifically shaped and matched to each other such that they can "zip" together, but only when the sheets are bent into the curve that you drew at the beginning. The result is amazing: free-form bent furniture parts that you can glue up without molds of any kind.

3D Layered Paper. Inverted Wine Bottle Planter. Introduction/Gathering Materials So a while ago I found a couple of Instructables about how to turn old plastic coke bottles and other various items into upside-down hanging planters (such as this one here).

Inverted Wine Bottle Planter

I thought it was kind of a cool idea, but it just looked far to scrappy to fit in with the rest of my place and wasn't something I would actually want to hang in my window or garden when guests come about… So I began thinking about how to make this idea a bit more aesthetically pleasing and decided that putting the plants into a planter made of solid material, instead of cheap plastic, was a pretty solid solution (no pun intended), which led me to wine bottles. Now this is my first Instructable, so any advice on how to improve on this is quite welcome (as I'd love to make more)… But since everyone has to start somewhere, here goes my dive into the world of Instructables!

For starters, let us grab some materials... Wooden mice by AlestRukov. DIY Indoor Seed Starting System. Since this is my first attempt to grow any plants, I wanted to start simple.

DIY Indoor Seed Starting System

Therefore, I chose to try to grow sunflowers and tomatoes. I assumed that sunflowers would be less maintenance than other vegetable plants because they're flowers. I'm not sure what my logic here was, but that's how I saw it : ). Also, sunflowers can have their seeds harvested and eaten, so not only do they look nice, but produce food. The seeds that are harvested can also be used to plant more sunflowers next year. IPhone Cover for Engineers. With everything going digital these days I started to think that current and future Engineering/Mechanical students are going to rely a lot on software to solve problems, it's happening now, I do it.

IPhone Cover for Engineers

When something new or something that we haven't done in a while in Engineering arises we always look for the easy/lazy way out, we either search the internet for an online calculator, software or look through the app store for a solution, but there's one thing missing, you can't touch it, feel it, assemble it, that's why I came up with, I believe, the first analogue Iphone app. You get this baby printed, you get a sense of achievement because you assembled it, you spin those little 1.25 module gears and admire it in awe.

The gears are all embossed with the number of teeth so you can work out ratios, there are even and odd number of teeth gears just to make it that bit more challenging, it's a great visual to see what direction what gear is going in a gear train. Crystal cMoy Free Form Headphone Amplifier. This headphone amplifier circuit is different to conventional modern construction techniques in that it is air Wired,P2P (Pointr to Point) or free form wiring just like in the good old Valve days before the intervention of PCB's and the transistor.

Crystal cMoy Free Form Headphone Amplifier

Rather than a traditional enclosure, the hole circuit is encapsulated in polyester resin to enhance the internals. If your reading this and thinking why do you need an amplifier for headphones then click here Although allot of cMoy headphone amplifiers are designed to be portable this one is designed for the desktop although a battery pack could be made also. The ChromoDisk. When I saw the Aurora LED 9x18 Instructable, I was inspired.

The ChromoDisk

However, it's built on the PIC microcontroller while I am most familiar with the AVR microcontrollers. Plus, I already have the development and programming environments for AVRs, so I set about a redesign as a personal challenge. I wanted to make something (almost) just as nice, that did not require as many components, was less expensive, and could be soldered by hand (albeit maybe taking a lot of time).

The result is this Instructable, the ChromoDisk. Giant LED bar graph. Metal Bender. No matter what your hobby, sometimes you need to bend some light weight metal into nice, circular shapes. This instructable will show you how to make a metal roller out of old printer rollers and some angle iron. So far, I have used this bender to make circles out of 1x1/16 aluminum for some of my hobby robots, to bend some 1x1/8 inch aluminum into a perfect circle for a US First Robotics high school team I mentor (Go Team 1631), and to bend two 5 inch wide 1/8 inch steel sheets 9 feet long for a fire pit I am making (but that’s another instructable).
