When I was learning to program in C/C++, for several days/weeks and on several attempts I hit the pointers plateau — that thing which, conceptually, I couldn’t get my head around sufficiently to really grok the damn things. I eventually took a class that spent three weeks on it and now I understand them — their purpose, their usage, their style and how to troubleshoot them. A couple summers ago, I took a geek vacation between jobs and worked my way through the NYU ITP Physical Computing class curriculum and dug deeper into some Arduino stuff.

After a couple weeks, I hit a plateau. I needed things like shift registers to multiply the number of LEDs I could manage with the Arduino’s 13 pins; I needed to use a 555 timer chip to get pulsing, and there was a whole range of chips starting named 74______ that were described as “hugely useful” or “workhorses”. These things were critical and basic, like pointers, but (like pointers) it was impossible to find documentation for them that was comprehensible to someone with my level of experience. It was one of the weird places where the web let me down. I must have done dozens of searches, asked everyone I could for help, and could find nothing. Which is a drag, cuz those chips are what give real ooomph to physical computing projects.

Make Magazine has fixed that with Make: Electronics, an unusually good book even by O’Reilly standards. It contains in-depth explanations of how transistors and logic gates work at the physical level — giving you a more intuitive sense of how to work with them (rather than following steps by rote); detailed descriptions of the pins at three levels: the official specs, the occasional nomenclature, and the actual function; and some simple circuits that show what the thing does. The last might be the most important. Even the most basic 555 Timer chip examples I could find had so much stuff going on that it was impossible to isolate the chip and learn, iteratively through tweaking the code, what the things does. To top it off, the Maker Shed Store has a components kit that pulls all the stuff (including jumper wires) together for you.

The one weird thing about the book is in the index:

What the hell kind of alphabetization system is this?

Of course, it’s not like I have time to do anything on my nifty hand-made workbench. But it’s nice to have it when I’m ready. Hope springs eternal. Put differently.

Ha!

Steven Johnson is one of my favorite writers. With the exception of Interface Culture, I would gladly see every one of his books (Everything Bad is Good for You, EMERGENCE, Ghost Map, and even The Invention of Air) be made mandatory reading people in digital design, digital strategy, digital marketing. Johnson goes deep into cognitive patterns, longer arcs of human behaviors around entertainment, information-seeking, and learning and provides great frameworks for understanding the features and technologies that are usually the center of gravity in digital discussion.

His Time article on the iPad does a nice job of setting the right tone for discussion. Rather than being millenial (Apple fanboys) or crotchety (iPad haters), he grounds the conversation in the longer arc of how we’ve envisioned computing in the last ten or so years:

If you time-traveled back to 1995 and asked the leading futurists of that time where our machines were soon to take us, you might well have heard just as much rhapsodizing about document-centric interfaces as that about hypertext and the World Wide Web. The first generation of software interfaces forced the user to think too much about the tools, the story went, and too little about the task. …

The weird thing about the iPad is that it has landed us 180 degrees from where we thought we were heading. The iPad interface — like the iPhone’s — tries to do everything in its power to do away with documents and files. There is no Finder or root-level file navigation. It’s apps, apps, apps, as far as the eye can see. According to the demo last week, the main way to launch iWork documents is by an internal document-selection process after launch, where your files are presented to you in a gallery format.

I truly don’t know how I feel about this. It might be genius. Maybe most users are more confused by Finders and File Explorers than I’ve realized. But I can’t help thinking that if the iPad really wants to be a device that you might take on a business trip instead of the laptop, it’s going to need a little more document-centrism.

Couple things to love here:

- pointing out that there is a widget-centricity to the iPad. Hadn’t noticed it, but now that I think about it, it sounds like a bad way to make netbooks suck less.

- The comment that “most users . . . might be more confused than I realized”, highlights another weird dynamic in the discussion — just how bad do laptops and netbooks suck? Aren’t hundreds of millions of people living with these supposedly “fatally flawed” devices? A lot of the dialogue about the iPad as netbook talk about how unpleasant people find computing, but is the problem of OS stability and feature bloat so bad that we need a neutered appliance to replace it?

And what a great writer Steven Johnson is. I’ve been scribbling in my notebook, in evernote and two blog entries (this’n and this’n here) to get this idea across:

The iPhone revolutionized smartphones, but I think we all accept that smartphones were in our future. There is no equivalent consensus that tablets or couch computers or casual computers are inevitably on the road ahead. We don’t even agree on the aims here: Is the iPad replacing the laptop or supplementing it?

Anyway, a great article.

One of the smartest designers I know gave a typically compact and smart assessment of the iPad:

DOA. Apple does better (in the last 10 years or so) when it re-imagines categories, not when it invents them. I’m sure I will regret saying this, but that’s how I feel right now.

It does a nice job highlighting Apple’s strengths (re-invent what’s out there after drafting on others’ experience in the market and with an unwavering focus on user experience), but it also hints at the bigger problem: it’s trying to be several categories (reader, netbook, bigger media player, game platform, web browser), under one technology (shiny, thin, touch screen, with none of those nasty mechanics that collect crumbs from your lunch) without being any one thing that is clearly needed.

While Apple often wins by delivering better versions of stripped down, less function-laden things like the iPod, the iPad is doing this across too many categories and likely to fail in all but one:

Reader Steve Jobs infamously said he would never do a reader because people don’t read anymore. He’s actually onto something — some people are passionate readers, while most do it casually. This means the number of passionate readers is too small for an e-reader to be as big as the iPod. The iPad won’t serve either audience well. It will suck for passionate readers: the battery life is dubious, the finger smudges will be a drag, and most important, the backlighting will be prohibitive. Jane Jepson, the creator of the OLPC screen and founder of Qi technologies (LED displays) likened reading from a computer screen to putting a flashlight in your eyes, it’s unsustainable for passionate readers. Casual readers won’t read enough for it to be worth dropping a big chunk of change and things like beach reading, subway reading will be dicey with a fancy device that large. The math will look better than the Kindle’s — spending $400 on a Kindle vs buying books is a quick and obvious decision for many — but the all-in-one argument is pretty weak when it comes to the reading.

Netbook Jobs’s digs at netbooks totally miss the value they have for people who like having a portable work device. The iPad doesn’t replace the processing power or precise mousing needed for real apps like word processing or spreadsheets with graphics, and it’s still unclear whether typing on glass for extended periods of time (like writing something longer than an email or entering numbers into a budget) works for people.

Bigger Media Player This one is tricky to guess, but I have a hard time picturing people dropping serious coin on a third screen that is bigger than their phone but smaller than their TV. Where would you use it? To watch something in bed before going to sleep? Is that worth the cost of getting a decent flat screen?

Game Player Again, a risky proposition. What’s the market for people wanting to play games bigger than the iPhone but smaller than their console? What do those games look like? They’ll lack the immersion of a TV or computer screen game because it’s too small, but will they add to the little games of the iPhone?

Web browser Right on! The video on apple.com references the superior web browsing experience of the iPad many many times, and they’re right. Having the iPad in the living room (with a remote built-in) so I can do quick simple email tasks (like writing “you’re very welcome” as in the video, or forwarding with “FYI”, or deleting what you don’t need) and look up baseball stats while watching the Yankees on an iPad is vastly superior to using overheated macbook or my crunched netbook keyboard. I do a lot of web stuff while I watch crap TV and baseball, and, as a reasonably affluent convenience-obsessed guy with some concerns about the aesthetics of my appliances, this might be enough to see my way clear to $500.

But that’s it. The iPad will be a high-end version of the web appliance that we all talked about several years ago. Only it will be too fancy to use while cooking (one of the standard scenarios we all gushed about), and much too fancy for us to call it an appliance.

It’s got a look (or maybe it’s the music):

The first 1:30 of the documentary Moog has a great line from Robert Moog, the inventor of the synthesizer and one of the parents of electronic music: “I can feel what’s going on inside of a piece of electronic equipment.” There are other passages in the movie (which has great tributes from electronic music performers such as Sun Ra, DJ Spooky, Mix Master Mike, Electric Skychurch and a wonderful animated title sequence), where he shows how visualizes the interactions of circuits and components. Interestingly, he also points out that his synthesizers are analog instruments, not digital ones and that he knows musicians approach the physicality of the electrical vibrations in the same way they approach violin, guitar, and piano strings.

Anyway, that close connection to material — which strikes me as a result of closely working and experimenting with them — as a source of inspiration, quality, and innovation is a theme near and dear to me. So, I clipped the movie and encourage would-be innovators and inventors to check it out. Moog the man is charming, engaged, lives a full life, and could be a more earth-bound person to learn from than Steve Jobs, Edison, and other lofty luminaries.

PS One last reason to watch the movie is a Schaeffer beer commercial in which a 70s-mustachioed dude in polyester, riffs on the Moog for 20 seconds before the jingle (”Schaeffer is the one beer to have when you’re having more than one.”) Worth the price of admission all by itself.

I’m taking a two hour class about bio-electricity where I also make a DIY ECG (electro-cardio-gram, the one for the heart). Signed up yesterday, and today, there’s a video of a guy (who’s headed to dental school soon, dunno why, but that seemed an interesting detail to add), who made a really simple one:

He has a funny bit at :45 where he mentions that he needed a capacitor to smooth out the current — when he was hooked up to the oscilliscope (one of his out put devices) he was picking up Spanish radio!

The blog entry is pretty fun as well. He has lots of fun extra detail.
