Looking to learn the basics of using the Arduino starter board? Well be sure to watch this informative video hosted by Massimo Banzi, one of the Co-Founders of Arduino.
The video explains how to build a basic circuit with the Arduino board, and how to use each of the basic components such as LEDs, switches, and resistors. So if you are new to engineering, or have only recently purchased the Arduino started kit, this video is a must-watch!
Documentation is not the work. You need to plan your photo shot in away that it records a sense of your artwork. This may mean you need to do a number of different things. A general installation shot to give an idea of scale and contextualising the work within the space. A cropped shot of a piece to display it clearly. A close shot to show materials and texture. A clear and straightforward recording of the work is what you should be after. Decide which material you wish to record your work in, i.e. colour slide film (transparencies), colour prints, black & white or digital. 8230;
It makes good sense to work with a limited range of well-chosen films. You get to know their performance intimately 8211; what each can contribute to your particular style of picture, its response to different subject situations and, when necessary, just how far you can abuse the film before results become unacceptable. 8230;
Film is, very simply, a light-sensitive emulsion on a plastic base. An easy way to think of film is to compare it with bread and butter. Think of the bread as the base, the butter as the emulsion. When you hold this combination in your hand, what you feel and see is mostly bread, the base 8211; not butter, the emulsion. The base (bread) holds and supports the emulsion (butter), the active part of the film. 8230;
How sensitive a film is to light, that is, how much it reacts to a given quantity of light, is indicated by its film speed. The more sensitive-or faster-the film, the higher its number in the rating system. 8230;
Most people8217;s experience of colour film will be buying a colour negative daylight balanced film. This means the image goes onto the negative film and then is reversed into a positive colour image in the printing process. 8230;
1. Your darkroom (kitchen, bathroom or cupboard) needs to be completely blocked out to stop light from entering. For windows use thick card cut to shape and held in place with blade canvas tape. 8230;see full text
Even if you have never developed a film before, you are unlikely to find it very difficult. You do not need a specially-built darkroom, and once you have loaded the film into the developing tank, the rest of the process takes place in daylight. 8230;see full text
It is important that you match the correct type of developer with your particular film being used or for specific results. For example, if push processing and you would like to keep grain to a minimum, you must use a fine grain 8216;speed enhancing8217; developer, such as Ilford Microphen. Other developers available include 8216;low contrast8217; or 8216;soft working8217; developers such as Kodak Technicol. Other developers are known as 8216;high acutance8217; developers, where acutance is a measure of the contrast at sharply delineated boundaries of light and dark tone. High acutance developers, such as Agfa Rodinal, emphasize grain structure and should usually be restricted to fine grained films. 8230;see full text
Push processing can help you shoot in very dim light. Sometimes the light on a scene is so dim that you cannot use a fast enough shutter speed even at the widest lens aperture. Pushing the film lets you shoot at a film speed higher than the normal rating by, in effect, underexposing the film. 8230;see full text
What developer does. Even after film has been exposed to light, the image is latent, not yet visible. Developer chemicals take the film to its next step by converting the exposed crystals of silver halide in the film emulsion to visible metallic silver. 8230;see full text
Your film may contain negatives that, at first sight, seem successful but reveal problems when you come to enlarge them. Check dry, processed film through a magnifier if there are signs of spots or slight variations in density. 8230;see full text
When your length of film is dry, cut it into convenient, easy-to-view strips of five or six negatives, and examine the results, The negatives on these pages and pp. 74-5 will help you to identify some common, but at first puzzling, faults. 8230;see full text
8216;Image quality8217; is a term which is applied to the ability of a film, negative or positive, to render fine detail. It is not a term which makes a judgement about the value of a photograph in respect of its content or ability to communicate a visual message. It is a purely technical reference. 8230;see full text

This tutorial shows you how to enter data in an online spreadsheet to generate a set of placemarks in Google Earth and Maps. Google8217;s web-based, collaborative editing allows you and your team members to simultaneously enter data and instantly publish updates. Using this tool you could: showcase your organisation8217;s projects, programme sites or partners; map your offices, volunteers or resources; or visualise your data on local, regional or global scales.
Some of the new and improved features in Spreadsheet Mapper version 3 include:
Create 1000 placemarks 8211; add more if needed.
Six simplified balloon design templates 8211; add more if needed
Simplified publication process
Additional customisation options
Spreadsheet Mapper 3 uses Google Apps Scripts to help generate the KML placemarks and to provide useful tools. If you want to use the older Spreadsheet Mapper 2, which only uses spreadsheet formulas, but limits the number of placemarks and balloon templates, you can still access it here: Spreadsheet Mapper 2.0 tutorial
Spreadsheet Mapper is a powerful tool for mapping point locations. It starts with enough spreadsheet rows for 1,000 placemark points and provides a tool for adding additional rows. Adding more than a few thousand rows/points will slow down the spreadsheet mapper and produce a very large KML file, in which case you may want to look at other tools such as Google Fusion Tables.
David Bourell of UT Texas describes how laser sintering works. This method of 3D printing uses a laser that fuses plastic powder, building up layer by layer somewhat same way as filament-based 3D printers do.
We all need to use them but hardly any of us know how to type them. Here is a brief guide of how to type smart quotes and accented characters (and dashes) on a Mac. If you have the latest OS you probably discovered that you can also find accented characters by holding down a letter to reveal its spicier cousins (I discovered this myself many times when attempting to type “heeeeeyyyyy” in an iChat window.). If you’re on a Windows computer or some nerdy space machine, I’d recommend googling “keyboard commands for accented characters”. If you use a non-English keyboard, you probably already know how to find all the accented characters you need. Made by Jessica Hische for your enjoyment and enlightenment.
These are dumb quotes: 8217; 8220;
Don’t use dumb quotes for quotations or apostrophes—the nerds will revolt. Do use them as shorthand for feet / inches.
These are smart quotes: “ ” ‘ ’
They are also known by the cuter term “curly quotes”.
This is how you type smart quotes:
Left double quote:
option + [
Right double quote:
option + shift + [
Left single quote:
option + ]
Right single quote:
option + shift + ]
This is how you type accented characters:
Any letter with ˆ above it:
option + i then release and type the letter you want accented
Any letter with ´ above it:
option + e then release and type the letter you want accented
Any letter with ` above it:
option + ` then release and type the letter you want accented
Any letter with ¨ above it:
option + u then release and type the letter you want accented
Any letter with ˜ above it:
option + n then release and type the letter you want accented
To type an å:
option + a for lowercase
shift + option + a for uppercase
To type a ç:
option + c for lowercase
shift + option + c for uppercase
This is how you type (and when you use) different sorts of dashes:
Here is a really long wikipedia article of how to use various dashes and below is my own shorthand version adapted from that information. There are more kinds of dashes than those mentioned here but these are the ones you’re most likely to use and confuse.
A hyphen: -
You know how to make this.
Used to break single words into parts (like when lines of type break within a word) or to join separate words into single words.
I love me some hand-lettering.
An en dash: –
option + -
Used in dates to replace “to” or “and”. It can also be used to illustrate the relationship between two different words.
I was in jail from 1976–1978.
Mother–daughter beauty pageants make me uncomfortable.
I have a love–hate relationship with stretchy denim.
An em dash: —
option + shift + -
For a break of thought similar to but stronger than a thought contained within parentheses. An em dash can also be used where a period (or full-stop) seems too strong but a comma seems too weak. At times it can have a similar vibe to a colon. Some non-Americans use en dashes in place of em dashes and add a space before and after them.
I once had to use the bus station bathroom—horrifying.
I tried a durian fruit once—tasted like hamburger pudding.

Stacey stores all of its content using flat text files & folders rather than a traditional database. So installation is as simple as copying the application files onto your server. No install file, no database setup and it will run on any standard php server.
sugru is the exciting new air-curing rubber that can be formed by hand. It bonds to most materials and turns into a strong, flexible silicone rubber overnight.
Developed by a team of product designers and materials scientists, sugru’s patented technology is unique in its combination of hand-formability, self-adhesion and flexibility when cured. It feels like modelling clay, and it’s that easy to use too. Once cured, its durable properties mean it’s comfortable in extreme environments from the dishwasher to the ocean to Antarctica.
Sometimes, flat just doesn’t cut it, and we need to find other, more attractive ways to present designs to our customers. One technique I’ve been using recently works remarkably well for text, logos and other vector artwork. It consists of taking a virtual photograph of the work by combining Adobe Illustrator and Photoshop filters. The [...]
There are quite a few quality stamped or distressed fonts available — Frankie and Frankie Dos, Roadkill, Battery Park, Hawksmoor, Chase, Coldharbour, Despatxada, FF Stamp Gothic, FF Confidential, FF Bull, Elephantmen to name but a few. Unfortunately ready-made stamp fonts present a number of drawbacks: repeating characters are identical (unless you have alternate glyphs), and [...]
