You might have heard about Adobe diving into the hardware scene this week with two new product explorations.

Mighty is a cloud-connected, pressure-senstive stylus, and Napoleon is a digital ruler and template tool bringing the efficiency of old-school drafting tools to tablets. Both address the fact that after decades of digital design tool evolution, designers still ditch them in favor of pen and paper for an important part of their creative workflows—sketching and natural drawing.

MindTribe led development of both Mighty and Napoleon.

Mighty and Napoleon, Adobe’s Drawing Hardware Developed by MindTribe

Mighty simulates a pen-and-paper drawing experience on the iPad as a high performance, pressure sensitive stylus. It’s also cloud-connected, to enable copy-and-paste across devices (say, from your tablet to someone else’s phone) and instantly pull down your personal content and preferences from the Creative Cloud to wherever you are.

Napoleon hearkens back to the drafting table era by allowing you to quickly draw straight lines and basic shapes, a là your T-square and circle template. Deceptively simple, this is one of those things that has to be experienced to be appreciated.

Innovative Hardware, From a Software Company

When you think of innovative hardware, you probably don’t think of software companies. When you think of being first to create a product to solve a user problem in a new way, you probably don’t think of a large company.

Furthermore, Mighty isn’t a hacked-together prototype. From the metal body, which is the smallest and thinnest-walled structure hydroforming vendors have ever undertaken, to the smallest ”rubber nib”-style tip of any active stylus available, to the pressure sensitivity mechanism users have said is better than any other product on the market, Mighty is an exploration based in hard reality.

How’d Adobe Do It?

Easy: don’t develop hardware the way most hardware is developed.

We use PowerPoint on a regular basis. So why did we have this quote on our wall?

Jobs quote

We agree with the instead of thinking part and hashing things out at the table. We’re not saying PowerPoint is bad.

Unfortunately for collaboration on engineering teams, though, it often is.

My personal MakerBot Replicator 2X arrived yesterday! I set it up last night and was printing within about an hour of unboxing it. Here are two test prints of pre-sliced designs that came on the SD card.

Shark and Cone

Some initial impressions:

  • Overall, the Replicator 2X is awesome and very fun.
  • Out of the box, it’s almost ready to go. You remove some zip ties, install a handle on the lid, plug in the cords, load the filament, apply Kapton tape to the build plate, level the build plate, and start printing from models on the included SD card. It took about an hour, with the build-plate taping and leveling being the longest setup step. The shark and the traffic cone each printed in under 1/2 hour.
  • While easier to use out of the box than a build-it-yourself printer, the hardware requires a lot of futzing. The build plate has to be manually-leveled, which is a critical step in getting the first print layer to uniformly adhere well. Adhesion itself is a problem—even with a level plate. My attempt to print directly on the plate failed (some have reported success by using hairspray or wiping it down with acetone first). After my attempt to print directly on the plate failed, I applied the included Kapton tape sheet & then the print adhered extremely well (it was a little difficult to remove).

Recently MindTribe held our very first hack day!  We took a day off to build a drawing robot inspired by the polargraph.  It was an opportunity for us to work together as a company, working on a single project (we usually split up into smaller, disparate teams for our client projects).  Also, it allowed to us to flex our interdisciplinary engineering muscles and take on different roles: electrical engineers masqueraded as mechanical and some ME’s took to firmware.

Success!

Lessons learned:

- Chant “minimum viable” all day long.
That’s what carried us through to completion.  Jerry repeatedly mentioned, “If we can just get it to draw a straight line, I’d be pretty happy.”

Steve also added, “Asking ‘Is this minimum and viable?’ as a group was far more effective than simply asking that question to only yourself. If I had something in my mind I thought was pretty minimum, taking the step of running it by the group almost always resulted in something even more minimum and viable.”

Yes, we left out tons of features:

- Lifting the pen on and off the canvas with a solenoid.
- Uploading an arbitrary picture and vectorizing it.  We framed our goal to the simplest denominator – the drawing program simply took in a list of (x,y) coordinates.
- Add limit switches so the pen doesn’t run off the canvas and we can let it draw unattended.
- Put the board on an adjustable stand with wheels.  To hold it up, we wedged the drawing board between two picnic tables and a couple of trash cans instead.

But more importantly, we got it done in a day.  Done and usable is better than perfect.

Some of you might be familiar with Chris Bangle. He revolutionized car design in 2001 with the BMW 7 Series (you can thank him for any car designed after that with a crease in the metal–car design the decade prior roughly followed that of a bar of soap throughout its useful life).

He spoke at Stanford recently and shared an interesting thought related to how we as engineers work with designers, and how the process of making things is just as important as the thing itself. His comments are likely to resonate with any engineer who has been involved in building high-touch objects of design, whether they be physical or virtual. I’ll skip you right to the comment:

For those of you not involved in product development in the last decade, Apple popularized making stuff pretty “at all costs”–meaning you’d better have a darned good reason if you’re an engineer saying something is impossible. Though design has always been an integral part of Apple products, it wasn’t until the original iMac was released in 1998 that a new relationship between designers and engineers was broadly forged. If you can appreciate the difficulty of making a translucent object the size of the iMac case without any tooling marks, you can appreciate that designers were now empowered to overrule when engineers said something was difficult or impossible. The power of the designer over the engineer was cemented with the original iPod in 2001 (exposed fasteners–tssk!), the iPhone, impossibly-thin keyboards, laptop enclosures carved out of blocks of aluminum, and numerous other examples.

This photo of a retired Lego mold sparked a lively discussion at a recent MT standup. The mold supposedly birthed 120,000,000 bricks over its career – an astronomical output considering that many sources claim Lego tolerances in the microns. Chet was impressed but a bit skeptical (imprestical?), since injection-molded parts typically have tolerances more in the range of +/-0.15 to +/-0.05mm. But everyone agreed that producing a billion parts per year that can each fit with any other part ever produced is an astounding feat. And they all snap together with just the same amount of force! But wait, Tom interjects, some of the Hsiu clan’s ancestral Legos don’t fit quite as well as newer pieces! Naturally, this left Mike no choice but to Google the unlikely phrase “ancestral legos,” eventually learning that not only can Legos survive across generations, they’re even used by some as an investment vehicle. Meanwhile, Sam reminisced about how his team used Legos in a project class, since the tolerances were so good that it was harder to do much better with machined parts. And Elisa mentioned a link she’d recently shared for adapters between Legos and other building sets. People have struggled in particular with Legos, however, since 3D printers can’t match the unusually fine tolerances of the production pieces. Heck, maybe it’d be easier to make a rapid prototype machine out of Legos rather than vice versa. Since 3D printers can’t yet compete on tolerances (or cycle time or per-part cost or material properties…), their current advantage comes down to enabling quick changes. Which is why we were initially wowed by the 3Doodler project that Greg found, though on further consideration it didn’t seem that useful for making things anyone would actually want to keep around. Yeah, Jerry chimes in, who’d want to litter their home with a plasticky stream of hilarious cat ornaments and seemingly plausible but in fact useless avante-garde kitchen utensils??, failing to convince anyone that that isn’t exactly what he wants, especially since he’s already placed a personal order for a MakerBot.

In conclusion, MindTribe loves digressions. Legos are pretty cool too.

Andrew “bunnie” Huang (of Xbox hacking and Chumby fame) recently completed a four-part blog series about manufacturing in China. It’s a great window on the work that goes into ramping up a factory for mass production and demystifies a lot of the ???’s between “Design Product” and “PROFIT!!”

MindTribe’s brave volunteers are back from CES, mostly detoxified, and just about finished digesting that last buffet brunch.

Much has already been written about the gradual demise of CES, its increasing bloat, and decreasing relevance. After all, the public can only absorb so many breathless announcements about giant TVs and Android tablets before it all becomes an incoherent blur. But CES still serves an important function in the industry – supporting the success of products that will be shown at next year’s CES.

Two big interviews with Apple CEO Tim Cook yesterday – one with NBC and another in Bloomberg Businessweek. Cook dropped the announcement that Apple is bringing some manufacturing back to the U.S.

It’s not known well that the engine for the iPhone and iPad is made in the U.S., and many of these are also exported—the engine, the processor. The glass is made in Kentucky. And next year we are going to bring some production to the U.S. on the Mac. We’ve been working on this for a long time, and we were getting closer to it. It will happen in 2013. We’re really proud of it. We could have quickly maybe done just assembly, but it’s broader because we wanted to do something more substantial. So we’ll literally invest over $100 million. This doesn’t mean that Apple will do it ourselves, but we’ll be working with people, and we’ll be investing our money.

A capital investment of this size represents a long-term commitment and a bet on the future of domestic manufacturing. It also signifies an interesting shift in strategy. After all, in a widely circulated NY Times article, when asked by President Obama why the iPhone couldn’t be made in the U.S., Steve Jobs famously replied, “Those jobs aren’t coming back.”

But there’s no reason why they can’t. Especially for high-tech hardware, the end product can greatly benefit from tighter integration between development and production, as well as closer control over manufacturing processes. As much as I enjoy filling my passport with stamps and expanding my collection of hotel toiletries, it can make a lot of sense to bring the factory to the engineers, rather than vice versa.

Are hardware companies testing the waters or turning the tide? At the very least, the media is growing more aware of a broader “Made in the USA” trend, as Jason Kottke notes. For consumer electronics, however, the challenge will be bootstrapping an industry that requires significant infrastructure investments in addition to an entire constellation of supporting suppliers.

“The consumer electronics world was really never here,” Cook said. “It’s a matter of starting it here.”

Everyone’s heard the fable from the ol’ grey-haired engineer about the time she had to add noise to a system to improve ADC resolution.  It seems like these stories are always heavy in the emprise and light in the details.  Well, here are the details.
