A Brief Introduction to the Arduino

Arduino:http://www.flickr.com/photos/remkovandokkum/2667608562/in/set-72157606159601535/

For Christmas, I got an Arduino. Well, really I got two coffee pots. Identical ones. So I returned one of them to Amazon, and used the refund to buy an Arduino starter kit. It’s a neat device, with a ton of potential. Here’s why.

Ok, so what is it?

The Arduino is an open, hackable microcontroller, designed to be easy to program and easy to build things with. Simply put: the ultimate hacker toy.

For about \$40 (or less, if you want to buy all the parts and build it yourself), you can have a device that you can program from any computer with a USB port, and that is capable of interfacing with the outside world. It doesn’t require any special training in electronics, and is ideal for experimentation. You can add an amazing array of sensors and add-on boards to allow you to do just about anything you can imagine, from reading the temperature to getting GPS coordinates.

Did I mention you can program it in Ruby?

What can you do with it?

Pretty much anything you want. You can start by making an LED blink - this is the hardware equivalent to “Hello, world”. Beyond that, the basic board comes with an array of inputs and outputs that you can connect up to all sorts of things: temperature and light sensors, motors, GPS modules. You name it, you can build it.

Here’s a quick rundown of a few things people have used these for.

This is only a fraction of what’s out there. An impressive community has sprung up around these little guys, and there is no shortage of cool projects documented on the web.

If you want to see the Arduino in action, check out Greg Borenstein’s presentation from RubyConf on programming the Arduino with Ruby, in which he demos an Arduino-based drum machine (literally, a machine that plays a drum with chopstics) as well as a board that uses windshield washer fluid pumps to mix screwdrivers. It’s one of the most entertaining talks I’ve seen.

Summary

In summary, if you’ve ever wanted to play with hardware, the Arduino is the place to start. It’s inexpensive, easy to use, and endlessly customizable. I’ve had mine a week and it’s been great fun so far.

Interview: Mike Rohde - Designer, Blogger, Sketchnote Artist

Introduction

Today’s interview victim is Mike Rohde. I’ve followed Mike’s blog for a number of years, and I had the good fortune to meet him at the inaugural SEED conference (see his coverage here and mine here). Mike has gained fame recently for his Sketchnotes - notes and hand-drawn pictures from events such as An Event Apart, SEED, and the upcoming SXSW 2009, but apart from that he is a talented writer and designer with a large portfolio of websites, logos, and other impressive work.

Thanks for agreeing to do this interview Mike. Can you tell us a little bit about yourself?

Thanks for the invitation Larry!

About me? I’m a kid from Chicago who loves to draw. I’ve managed to find a profession that allows for and encourages drawing and sketching skills.

I’m a designer and art director, with experience in print and the web, with a passion for usable, practical and good-looking design solutions. I’ve always had a technical side, being fascinated with computers and technology since I was a young kid.

Fortunately for me, web design and working with technical people in my work is a great fit, because I can share my design skills but also relate well to the technical nature of projects and technical people.

I’m also a blogger since 2003 at Rohdesign.com where I share my thoughts on life, design, technology, visual thinking, music, cycling and whatever else I feel is worth of sharing with the world.

I’m a husband and father, follower of Jesus and a coffee fan.

Design

Until recently you worked as Art Director for MakaluMedia. For those of us not in that field, can you describe what an Art Director does?

Funny you should ask because your question reminded me of a A List Apart article on this very subject by Stephen Hay:

http://www.alistapart.com/articles/artdirweb

I liked this quote from the article, showing how subjective the role of an art director can be, based on the discipline they’re in:

“In the movies, art directors are usually responsible for creating the “look and feel” of the film. In advertising and print work, art directors (often teamed up with a copywriter) come up with “concepts,” the creative ideas which communicate with us on a gut level through such devices as theme, metaphor, and symbolism. Some art directors do little more than dream up these ideas and present them to clients, while some oversee almost all aspects of the design and production process. Surprisingly, art direction is seldom taught in schools and there is very little formal information on the subject; it is often learned in practice.”

In my view, an “Art Director” is a designer with a 50,000 foot meta view of design projects they work on. They are involved all the way from listening to the client and stakeholders on a project, through the conception of an idea to the design, development and production the idea.

The art director is responsible for maintaining the vision of a design idea, as much as is possible (or reasonable), to achieve the final result. This means maintaining consistency in the project design, structure, usability, colors, brand or identity and anything else related to the design.

It also means working with the client to maintain these goals as well as any team members producing the work, in my case developers who would code the sites and back-ends for web applications. As an art director, I feel I represent the user. I’m responsible for making sure whatever I’m directing — a logo, an icon, a website or printed item — is communicating the message my client wishes to send, effectively and simply.

After many years as a senior designer I began to realize that while I enjoyed the design aspect (and still do), I especially enjoy guiding a project’s consistency between concept and completion, and continuity between multiple items a company produces (website, business cards, brochures, etc.). That’s when I felt comfortable calling myself an art director.

You have blogged about the process you follow to develop. Can you summarize what you do to get from a concept to a finished product?

First, I ask lots of questions, like “What are my client’s goals? What is my client trying to achieve with this project?” and so on. I want to know the ultimate reasons for what we’re about to do, because sometimes what a client proposes may not be the right solution for the underlying challenge.

Once I understand the challenge, I read my notes, and synthesize the goals for sketching. I use pencil sketches to help work out ideas that can solve the challenges I’m facing. These sketches are presented to clients with what I call “rationale notes” explaining the whys of my design concepts.

I’ve found sketches invaluable to solving problems before I ever get to the computer to produce my designs. Some designers may be afraid to show clients their conceptual sketches. I’ve found that showing my sketches to clients is an effective way to share my process, while leveraging my client’s knowledge in solving the problem. Showing sketches draws the client in, making them a part of the solution

What are the tools of the trade for you as a designer?

While computer tools like Adobe Illustrator, Fireworks and Photoshop are important, I feel my most important tools are my pens, pencils and sketchbooks. I have several sketchbooks I use to solve design challenges with pencil or pen, before I even get to the Mac.

On the Mac, I’m a big fan of Adobe Fireworks for web design and icon design, since it offers very useful vector tools. I’ve been an Adobe Illustrator user for many years as well, which I think makes Fireworks a natural choice.

Where do you look for inspiration? Do you have favorite sites or books, or do you just observe things around you?

I have lately been looking in a variety of places for inspiration. As a web and UI designer and art director by day, the applications and sites I use daily provide inspiration to me.

I’ve found friends on Twitter suggesting great articles and design inspiration, which is one of the reasons I find Twitter so valuable as a designer. I’m happy to see so many design professionals tweeting.

http://twitter.com/rohdesign

Even everyday items and design solutions provide insight and inspiration for me. I love hand-painted signs and am always aware of packaging in stores, and other design elements I encounter in my everyday life.

Some sites I enjoy checking out for inspiration include:

http://ffffound.com/
http://www.alistapart.com/
http://www.designobserver.com/
http://design.alltop.com/
http://logopond.com/
http://delicious.com/tag/design
http://www.underconsideration.com/speakup/

I find inspiration to be best when it’s random and not too planned. :-)

Sketchnotes

You’ve gained some fame lately for your Sketchnotes. 37Signals linked to your sketches of the Seed conference (which I covered as well, though not nearly as graphically), and your notes from SXSW have been ever more widely covered – including Boing Boing). Where did the idea for Sketchnotes originate?

They’ve been brewing for some years now. I’ve always been one who sketches and doodles, as well as being a long-time note taker, but back in 2007, I made a decision to intentionally combine the two at the Adaptive Path’s UX Intensive workshop in Chicago:

:http://www.flickr.com/photos/rohdesign/sets/72157604109069527/

It was well received and I enjoyed the process — so I kept doing “sketchnotes” at other events like SEED 1 and 3, SXSW Interactive and An Event Apart just this past October. Sketchnotes seem to be very well received by attendees and non-attendees alike.

Now I’m being brought on at events as an official “sketchnoter” to capture the event from a different perspective. I’m very excited about this opportunity to become a resource. In fact I’ll be at SXSW Interactive 2009 as an official sketchnoter this March.

I’ve found that taking copious amounts of notes helps me stay engaged in whatever I’m listening to or else my mind tends to wander. Do the Sketchnotes serve a similar purpose for you?

Yes. I find taking notes and sketching really reinforce what I’m capturing in my head as a speaker talks. Sketchnotes are not meant to be word-for-word stenographer notes, but interpretive. I capture what I feel is important, which makes sketchnotes personal.

However, because someone is actively listening, processing and selecting important ideas, sketchnotes have personality. What they maye lose in fine detail is replaced with a concise, personal way of capturing the moment.

Sketchnotes were intended for myself, but as I began posting them on Flickr, I found others who had attended the same event connecting with them. Even more surprising for me were those who hadn’t attended the events seemed to enjoy reading my sketchnotes. Very cool stuff.

You developed and sold a calendar of coffee-themed sketches this year (which I received as a Christmas gift from my wife, who apparently knows me too well). Will there be more products coming (ala Hugh McLeod’s prints and business cards) or was that a one time experiment?

Right now I’ve focused on the Sketchtoon Coffee Calendar, producing another edition of the same calendar for 2009:

:http://www.cafepress.com/rohde.40227192

I’m contemplating several different ideas that would create other products for my and sketchtoons, but I’ve been so busy with work and otheractivities, new product development has been on the backburner.

Thanks again for the opportunity to share about my work and thoughts Larry - I especially appreciate your interest in my sketchnotes and sketchtoons!

The Coming Decline of Rss and Atom

Ever since I discovered Bloglines some years ago, I’ve been hooked on RSS. I subscribed to a slew of feeds and treated it like a to do list, always trying to get it to zero. Subscribing to those feeds enabled me to see and learn about a lot of things I wouldn’t have seen otherwise.

Since that time, RSS feeds have been my primary source of what’s new and interesting in the world of technology. Along the way, the feeds I was subscribed to changed, as my interests changed, and I gave up Bloglines for Google Reader. But my appetite for feeds has only grown.

Lately, though, I’ve seen a shift. Most days, I skim the headlines in Google Reader, looking for specific sites, without ever getting the unread count down to zero. What I’ve started noticing is that even when I was keeping up on RSS feeds, I had already seen all of the interesting stuff. The primary reason for this is Twitter.

Twitter is my social network of choice. Yes, I’m on Facebook (though I succesfully avoided it for a long time), and I’m also on LinkedIn, but the place I spend most of my social networking time is Twitter. Most of the people whose blogs I’ve come to rely on for news and insight are people I follow now on Twitter. I get more frequent links and thoughts through that site than I ever would through a blog, and it’s much more real-time than RSS. There are a number of sites which even offer to send you notifications of new content through Twitter in addition to RSS, like RubyFlow.

Additionally, I think sites like Reddit and Hacker News are having a similar impact. Their voting functions help to filter through the haystack to find the best stuff and ensure that it rises to the top - at least in theory, I’m not convinced that it always works in practice.

Perhaps the future of RSS and Atom lie as protocols that enable applications to share information rather than as a consumer-facing application of it’s own. They’re the plumbing, not the faucet.

While I still use RSS, and won’t likely be shutting down Google Reader any time soon, I find that the interesting things seem to find me, rather than me having to wade through feed after feed to find them. This is a byproduct of me being connected to a group of people on Twitter with similar interests, who share things as they come across them. I’m questioning whether my use of RSS will decline as I consume more information this way.

I’m curious if anyone else is experiencing the same thing.

Some Software Was Harmed in the Making of This Site

As noted on the about page, I decided to write my own software to run this site.

The following technologies were harmed in the making of this site:

VPSLink has good deals on VPS hosting. I pay \$24 per month for a 256mb VPS, with impressive uptime. I originally intended to go with Slicehost, but they had no slices available at the time (and didn’t for several months as I recall), but I have not been dissapointed with VPSLink.

Ruby on Rails

I haven’t found a better platform for developing web applications yet, although I’m keeping my eye on the up-and-coming web frameworks in Ruby, Clojure, and Scala. With the merging of Merb into Rails 3, Ruby on Rails looks to get even better.

MySQL

Actually, I like PostgreSQL better, but I run a Wordpress site on my server that needs MySQL so I’m using it for this site instead of running two database servers. I actually tried deploying with SQLite originally, but I ran into issues with it. It takes some doing to make MySQL run well on a memory-constrained VPS, but it’s possible (tip: don’t use InnoDB).

Blueprint CSS

Developing complex layouts that work cross-browser is painful. Blueprint is a CSS framework that makes it less so. It’s currently only used on the administrative portion of the site, but I plan on reworking the main layout with it as well. I’m also planning on playing with 960gs, which is similar (better, in the opinion of some).

jQuery

JQuery is really, really good. I could go into all the reasons why, but Chris Wanstrath and PJ Hyatt already did. I’ve used Prototype for a number of years, and JQuery just seems to fit better. There’s a huge library of plugins available as well. The only downside is the somewhat light documentation available for it, although that seems to be changing.

Capistrano

Here’s my rule for web application deployment: Automate the Very First One. This really makes all the difference in the world, especially for side projects like this. When deploying is trivial you will do it all the time. As I was working to get this new site out the door, I spent part of an afternoon at the local coffee shop to fix the few remaining issues with the code and get the server configured. In that time, I deployed the site 6 times. My point: deployment has to be easy or you won’t do it. Capistrano makes it easy.

Phusion Passenger

I’ve always used Mongrel for hosting Rails apps but Passenger (aka mod_rails) is the new hotness in Rails hosting, and with good reason. Once it is configured on your system, web deployments become very easy. There’s almost no setup, and you don’t need all of the monitoring infrastructure that mongrel requires. It runs under Apache, and as a result uses somewhat more memory. This is certainly offset by the ease of use and administration.

Ruby Enterprise Edition

Provided by the same folks who brought you Passenger, REE reduces the memory usage of your Rails application by roughly 30%. On a memory constrained VPS such as mine, this is a huge deal. I was a little concerned about running a different version of Ruby than the one I was accustomed to, but lots of people are running REE these days, and to date I have had no issues.

So that’s the tech behind this site. As I add some additional functionality here, I will be bringing in a few other things, and I will write about it as I go.

Git

Git has a steeper learning curve than Subversion, but it’s definitely worth learning it. It’s blazing fast, clean, and has some impressive features, particularly around merging. For this project, I just used it locally, without ever pushing to a server. I’d recommend using it even when you’re not collaborating with other developers.

So, what did you use to build your latest project?

Welcome to the New Site

I’ve maintained a blog since sometime in May of 2005. As with many blogs, posting regularity varied. Sometimes it was daily, sometimes a month or two would go by with nothing new at all.

This is something different.

The content on the old site changed over time, just like it’s author. Interests come and go, technologies that were once shiny and new have lost some of their shine. I stopped writing short posts that were mostly links to other people’s content, and starting writing longer articles. I did some interviews, and a bunch of book reviews.

Then, as is prone to happen, I got busy. In the time I’ve been writing this I’ve gone from having one child to having three. My job responsibilities have changed. This site got a bit neglected as a result.

So a while back I started thinking about the site, and what I wanted it to really become. And I thought. And then I thought some more. My thoughts evolved over time, and I’ve settled on what I’m launching here today.

I’m a curious person, and always have been. My interests are varied, and change often.This site is a reflection of those facts. Some of the content from the old site has been migrated to here, much of it was not as it was either not relevant or didn’t fit well with the new site. The focus of this new site will be whatever happens to have my interest at the time: mostly technology, software development, and entrepreneurship, but extending into other areas as well. I will continue to do interviews and book reviews, and have several of both to publish in the very near future.

I hope to write here on a more consistent basis, but they will be longer articles and as such it’s not likely to exceed more than once or twice per week. I’ve created a new section just for links to interesting things, called Curiousities, and there will be content there daily.
