xref: Physical Computing’s Greatest Hits (and misses)

Been busy, but time for a quick xref: Tom Igoe has a really nice write-up of common projects in physical computing classes. More importantly, he explains why all these (often) obvious projects are still worth doing in class and why students shouldn’t feel like they’re just duplicating someone else’s efforts.

Universities and the 21st Century

If you’ve been living under the same rock I hang out under, you might have missed that John Maeda is now President of RISD.

Yes, that John Maeda and that RISD.

So, pretty cool, huh?

What’s even cooler, is that Maeda is blogging regularly about RISD-related stuff at “Our RISD“.

I’ve never met Maeda and I’ve little desire to go to RISD at the moment, but I appreciate the opportunity to reading the thoughts of someone whose work I respect and admire and get a behind-the-scenes look at a major design school.

Simplicity and Octopart

I like simple things. While I often like gaudy, baroque, Victorian, overdone decoration, I like things I use to be as simple as possible. I don’t feel the need to make arbitrary rules like, “no buttons anywhere on the product”, but I try to make things simple and keep them that way.

Visually, this is a pretty boring journal. But journals are about words, and because I stay focused on words, it’s easy to read this journal on just about any device, from my XV6800 phone to a high-end PC. (Just checked and it looks pretty good in lynx as well.) I spent very little time making it simple, I just started ripping things out if I couldn’t justify their existence. So, there’s no autobiographical photo, no fancy widgets showing what music I’m listening to right now, no countdown-until-W-is-gone clock, do dynamic code generation, Flash animations, or any of that. True, if I were a freelance graphic — sorry, “communication” — designer I’d probably put a lot of effort into having a rockin’ web site that shows off my chops. But I’m not, so I don’t.

So, back to simple. If you’ve ever ordered anything from a supplier like Grainger or DigiKey, you know what a nightmare it can be to find what you’re looking for. For awhile now, McMaster Carr has gotten more of my business than, say, MSC Direct, simply because the McMaster Carr site is so damn simple and easy to use.

McMaster Carr is great for the hardware I’ve needed for some metalworking probjects, but in the past year or two I’ve also gotten back into tangible computing (aka “making electric things with embedded CPUs”). The work I’m doing now is mostly based on the Arduino, an AVR-based single board computer. The Arudino does for physical computing what high level languages did for programming — open the field up to more people by simplifying the interface and the programming environment. Yea for simplicity!

Getting back into tangible computing also means dealing with the dreaded mail order supply titans like DigiKey, Newark, Mouser, Allied, etc. Typically when you’re ordering parts, you make a list of what you need, then try and find each part in each catalog, get the price, sum everything up, figure out shipping, then go find out if the parts are actually in stock. It’s an hour or two with a spreadsheet and often both the online search engine and the printed catalog.

Octopart changes everything. It’s a search engine for electronics, but more importantly, it pulls data from all the major vendors and shows you — in real time — pricing and availability. You can make a parts list, then easily compare prices and availability across most major vendors then build individual shopping carts and place orders.

It’s an amazingly useful resource, but most importantly, it’s simple. Simple, simple, simple. There are no garish colors, no image maps, no egregious animations, no masses of corporate logos showing everyone they are affiliated with. Just plain text, thumbnails for search results to help identify parts, and navigation that doesn’t require FPS-developed reflexes.

Go play with it — even if you don’t know anything about electronics — and see what you think. If you think you’re ignorant of things electronic, then search for something you’ve used or heard of, like “9v battery” or “transistor” and just poke around a bit. By keeping things simple, they’ve taken something very complex — component selection and ordering — and made it a much easier task.

Positive and negative examples

A few things I’ve wanted to write about in detail but I’m kinda swamped with work and school.

Ishkur’s Guide to Electronic Music. A collection of graphs showing the history and interconnections between various genres of electronic music. Lots of samples and written descriptions to go along with the graphs.

Processing, a new environment from Ben Fry and Casey Reas. Processing makes it easy for non-programmer types to do simple visualizations of data. Processing built on Java, and programmer types can easily take advantage of the full Java environment if they wish.

A Timeline of Timelines, from Cabinet Magazine.

James Victore will speak at Carnegie Mellon on Monday, March 19 @ 7:00 pm. His topic:
“Graphic Design Just Isn’t That Interesting: A discussion of the role of the designer in relation to ethics, morals and selling crap to people who don’t need it.” Margaret Morrison Breed Hall, Carnegie Mellon, Pittsburgh, PA.

Visual Complexity, a blog about complex visualizations of data.
