“Game on”, as they say.

A sea change at work has made me remember it’s good to get off the ship while it’s in the harbor and I did. I’m still going to look around for a nice gig at someone else’s firm, but while I’m doing that I’m also going to be putting pencil to paper, soldering, printing, lasering, and welding.

What makes me feel good about this is how quickly some work has shown up. It’s not a for-a-living level of work, but it will be great additions to my portfolio and CV, and lead to more work.

For you digifab types, I’m also cranking up my lasersaur, reprap/makerbot, and general digifab hacking at the nerd blog.

However, after bonking my head in the basement I also found the latest Jameco catalog, and something about it just isn’t right.

sigh.

The goal here is to chart out all the possibilities in an attempt to get people thinking about tactile/haptic feedback from some new angles. Honestly, if I see one more tactor-anything I’m going to hit with a hammer. Enough with the pager motors already! We have 5 senses (arguably 20-something), let’s use more of them.

Starting out, I’m using a simple tree: person -> body part -> sense

person->finger->pressure (sensitive)
person->finger->temperature (sensitive)
person->arm->elbow->temperature (normal)
person->leg->foot->sole->pressure (weight)

So, two questions:

1) Has someone already done a good job of this and I simply haven’t found it yet?

2) Is there a preferred format for this sort of thing that’s easy to mail around and text edit?

(p.s. Yes it’s arguably a folk taxonomy but I’m in no mood for pedantry.)

I discovered this while getting ready to assemble my Mk.7 Stepstruder and realized I could print another pair out faster than I could dig through the entire house looking for the first set I printed.

Which makes me wonder — why can’t I do this when I can’t find the cap for my pen or some random generic plastic part for a battery pack? If it’s easier to print one out than find it, what happens when I find the one that I lost? Toss the one I printed in the Imaginary ABS Recycling Bin?

In 15 words or less, complete this sentence: “I want to be a designer because…”

“they solve problems, and I want to teach other people how to solve their problems.”

Is the answer different? In my limited experience, yes. You can make a lot of useful things with a laser cutter, but it’s not as trivial to own as a 3d printer. To begin with, the laser cutter is far more dangerous to operate than a 3D printer. Most of us think of cheap red laser pointers when we think “laser”, but those a far cry from a Class IV “cutting” laser that can sever a finger or permanently blind you.

Oh, and it’s invisible. An invisible laser that can permanently maim or kill you. Thus the various safety interlocks that prevent the machine from operating when the door is open, just like a microwave oven.

That being said, I think laser cutters are in the same class as “professional” 3d printers used in manufacturing. It’s probably not something you would own as much as something the local co-op or library or commercial printing shop would own, maintain, and use for you. When you need a stack of flyers printed and go to the local print shop, they run the machine for you, it’s not going to be much different than that.

The other issue is finding a place to use it safely. Laser cutters are safe to operate in self-test/alignment mode, but as soon as you start cutting and etching you run into the problem of toxic fumes.

Most of the media I’ve seen go through a laser cutter has been acrylic, polycarb, and other plastics — all of which generate some seriously nasty fumes when they are etched or cut. My experience is that the warnings in the Plexiglass(r) MSDS are %100 correct. Not only do you need space for a laser cutter, you need an exhaust fan that can move a lot of air outside very quickly. (The commercial Epilogs I’ve used had fans that were loud enough to drown out normal conversation, I don’t know who specified them so they might have been overkill.) Cutting / etching wood has similar problems — lots of smoke from the wood and whatever byproducts come from burning the glue if you’re cutting plywood. Paper’s not really a problem, and cutting PVC and some other materials will actually destroy the lens so those aren’t cut in the first place.  [Edit: When laser cut, PVC releases free chlorine gas which combines with atmospheric oxygen to form hydrochloric acid which is bad for the mechanicals.  I suppose If you had a laser cutter filled with an inert gas it only be a matter of safely disposing of the exhaust gases.]

So going back to the original question, I think the answer for now is “because they can”. If you have the space (a big garage or a studio/hackerspace) and time (I’ve got 50+ hours into my lasersaur build) it’s certainly an experiment worth trying.

Currently there’s just an antenna mount of interest only amateur radio people, but I’m working on a few more items on the store that I am prototyping with my Makerbot Cupcake before uploading to Shapeways.

Recently I picked up a Barnes and Noble NOOKColor. It’s an Android-based, e-reader/tablet with a good web browser and PDF display package. I don’t plan on buying many e-books (I prefer paper), but having something bigger than a phone and smaller than a laptop that can display a PDF or browse a “howto” site while I’m in the studio is seriously useful.

Except for one slight problem.

Like most tablets/e-readers, it’s meant to be hand-held and not parked on a bench. If I lay it flat on my bench it’s hard to read, and while it was amusing to have my hand model hold it, that didn’t work well either.

So after a frustrating day of trying to use it to browse instructions on some MakerBot mods…

[facepalm]

… a trivial NOOKColor holder.

I had an idea recently for a different way of making ground plane antennas for the 2M band. Don’t worry about what they actually are, suffice it to say that they occupy a lot of volume and are a pain to transport. Imagine a pyramid made out of four 60cm coathangers with another 60cm coathanger coming out the top of the pyramid and you’ve got a typical ground plane antenna. On the other hand, they’re cheap, easy to build and can be tuned/adjusted with the SWR meter in a decent VHF radio.

(Ok, that’s pretty much all the geek stuff out of the way. See, that wasn’t so bad, was it?)

So here’s the problem. What if you want to toss a ground plane antenna in the back of your car, carry it somewhere on your bicycle, or have it as part of an emergency “go bag”? Are you really going to cart around a delicate bit of metal sculpture that occupies a rectangle a half-meter on each side and a meter tall? No, you aren’t.

This became a problem with an interesting combination of design and fabrication: How I could make it easier to transport and store but still be easy to set up and function correctly as an antenna? The idea of making it fold up seemed like the most obvious solution, but folding means moving parts which means more chance of coming apart. However, most people use this sort of antenna in a fixed location, often inside an attic or outside resting on a flat surface. At worst it might be used outside in windy situation and I’m thinking about a second version for that sort of environment. I started my process with the traditional sketching but instead of making foamcore models I decided to fire up the MakerBot Cupcake I built last winter and start out with ABS prototypes.

Total time spent modeling and printing each iteration was about an hour, and it was easy to fit that in at night after dinner over a few nights. The first few didn’t work very well but I quickly hit one that did work and that was a relatively simple piece of plastic. (Ok, it worked better after a bit of filing and sanding, but it worked.) Within a few minutes I’d bent and cut some welding rod, soldered a stick of it to an adapter, tweaked the resonance a bit, and I had a working antenna for not very much money.

The problem quickly became “How do I share this with other amateur radio operators?” Sure, I posted the STL on Thingiverse, but you have to own or know someone with a 3D printer for that to be of any use.

I think the answer is going to be Shapeways. I’ve ordered printed items from them in the past and while they aren’t cheap, they have wonderful print quality and ship worldwide. I’ve started the process of setting up a store there and in the spirit of Amateur Radio will offer my antenna mount for minimal markup.

In a few months we’ll see how this experiment worked: Can a design concept prototyped on a hobby 3D printer be turned around and sold for a small profit by a commercial fabrication shop? What are the unexpected surprises or hidden gotchas that need to be solved for this to be more than a hobby and instead a viable business model?

This was two light sources — the sun and a fill flash, no Photoshop involved — Scott explained how to set this up in about an hour of live demonstration. (And yes, that really is a Gerber Mark II. :-):

Natural light from one window and not much else. And no, it’s not real. It’s a $10 prop from eBay with an edge duller than most butter knives:

One thing I really enjoyed about working with Scott is that he made us take lots of test photos, some of them came out as good as the “real” photos. Here’s one where I was trying to balance natural light from outside with light from a lamp:

“I want to be a designer because …”

…I like finding and solving wicked problems, and design is full of them.

Until yesterday, that is, when my partner tripped and broke several foot bones that are needed for things like walking and driving and the like. So not only are crutches involved, but we live in a two-story house with the bath upstairs, kitchen on the first floor, and laundry and storage in the basement.

We knew our 1950s house was nowhere close to ADA when we bought it, and we often joke about how ADA-hostile Pittsburgh is in general.

I guess now we’ll get some first-hand experience as to just how bad it is and what we — as designers — can do to help fix things.

Adding to the workload is the fact that I’m a homeowner in the northeast which means I have to cram most of my home improvement work into a few summer months. In ~6 weeks, the house will be sporting an environmentally friendly rear deck and stairs made of locally sourced black locust. I want to avoid synthetic/composite decks, sealing a cedar deck every 2-3 years is a pain, and there’s no redwood to be had this far east. I was whining about all this when a friend of mine from Pittsburgh suggested black locust. It’s a regional hardwood that has evolved to deal with the local climate had has an outdoor rating of 75+ years without being painted or sealed. It isn’t as cheap as pine and cedar, but the thought of having a deck that will easily last 50+ years with no maintenance makes me quite happy.

The DSLR is a great tool for documenting 2d and 3d design, but for 4d design you really need something that can capture video. (It’s true that some DSLRs now capture stunning video, but only for short durations and quantities and you’re still lugging around a full-size camera.) My “should have brought the video camera” regret kicked in as soon as I started experiencing how differently Japanese people interact with technology and their environment. Sure, I could take lots of photos and copious notes, but those aren’t nearly as good as 10-15 seconds of video.

It’s not just recording video that’s important, it’s being able to record video conveniently, in high quality, then easily move the video off the camera. With my full-size, miniDV video camera it’s pretty much impossible to take quick snippets of video given the overhead of getting it in/out of the case, turning it on, etc. On the other hand, the TGV5 is small and light enough that I can carry it in my pocket and within a few seconds have it out and recording video. (It’s even faster than getting my Droid out and recording.) Cheap/free software makes it trivial to take a 10-20 second clip, trim it if needed, then “Save As” for Flickr or Vimeo.

As an experiment I’m starting to document design — especially 4d design — using only short video clips. I’ve posted a couple of short clips to a new flickr set, “Japan + Design” which I’ll be filling with video and still clips as I get around to processing the backlog of photos.

There’s no chance of my getting rid of the DSLR any time soon as there’s no substitute for huge glass when it comes to taking good photos. However, I have stopped lugging it around unless I’m intentionally on a trip to take hiqh quality photos as the TGV5 is becoming my “go to” camera for documentation and swipe files.

A million or so Internet years ago, I scored an AT&T 3B1 in lieu of back pay and set up a UUCP node by the name of “flatline”. I handed out a few shell accounts to friends who not only owned a computer but a modem as well. In doing this, I had joined a tiny group of people who would soon write an “@” sign on their name tags when attending a convention and coordinated “@-parties” to get together and exchange email addresses and UUCP connection information.

We were not mainstream computer science types nor were we socially incompetent basement-bound computer geeks. We were people who believed that electronic communication was the future. We thought it was great that we could send email for free from the US to other countries and that we could have an international messaging system that transcended operating systems and (most) human languages. We didn’t just think it was a good idea, we went out there and made it happen.

I had found, in a way, my tribe. It was a great feeling to hook up with a crowd that was both diverse in source population but of a similar mind when it came to goals and activities. We were libertarians, democrats, dead-heads, skate punks and full-on computer nerds, we argued about damn near everything, except we all agreed that electronic communication was the future.

When I moved to the Bay Area to work at startups I had a similar feeling, but the crowd was too big and the connections too many to have that real feeling of “my tribe”. There were so many of us that we belonged to something larger than a tribe but smaller than a nation. It was good, but not as good as the small tribe.

“Now that I told you that story, I can tell you this one.”

For the second year in a row I’ve attended the IXDA “Interaction” conference. It’s a small, focused conference of people who are interested in interaction design in all its forms.

Last year I was still in design school and went completely fanboy after the event. Now I’m not ashamed of that because the thing I love about going fanboy (or seeing one of my friends go fanboy/fangirl) is the honesty of the emotion. The self defense drops away, the unfiltered gushing cranks up, and while everyone is a little embarrassed afterwards there’s no doubt that the emotions and feelings expressed were honest if not a bit poorly worded.

This year I still “feel the design love” as we say at Carnegie Mellon, but I feel something different as well. I feel like I’ve found a new tribe of people from diverse backgrounds but with similar goals. Whether or not I’ll end up being a member remains to be seen but I’m looking for ways to prove myself.

For three days we’ve talked about all sorts of little-d and big-d design over meals and at bars. We’ve sat in boring talks and talks we wish would have went on for hours. We’ve traded business cards, scribbled notes on napkins and yelled ourselves raw over DJs playing dance music. We’ve drank too much, ate too much, and probably pissed off all of our twitter followers with a seemingly endless stream of #ixd10 tagged messages.

And I’d do it all over in a minute.

Ok, maybe a week or two. I need some time to work off some of the shrimp-grits and pulled pork and sweet tea.

Here’s hoping we see one other before IXD11 in Boulder, CO.

If you have the budget to buy a production-ready 3D printer, you probably shouldn’t be looking at a MakerBot. Production systems have better resolution, support contracts, schmancy STL conversion software and all sorts of other niceties. The MakerBot Cupcake is not a Stratasys, you’re not just going to plug it in and be cranking out pretty models a few hours later.

However, if you don’t have a huge budget and you’re willing to spend time debugging, tweaking, and generally getting your hands dirty; if you’re ok with the smell of ABS fumes, the stepper motor “songs“, and tending to an occasionally fussy machine that will botch a part for no obvious reason; and if you enjoy hacking and iterative exploration of technology, then maybe you’re the right sort of person to put together a MakerBot Cupcake or other reprap-based 3D printer.

Home scale fabrication is the domain of garage-carpenters and basement-machinists, the MakerBot doesn’t replace either. To some extent, building and running a MakerBot requires some of these related skills. Do you have a feel for how tight you can turn a bolt holding two pieces of wood together before it snaps the wood? Do you know how to shorten a screw with a hacksaw and keep the threads clean? You already own a multimeter, do you have a thermistor probe as well? How are you at diagnosing a wiring problem in a stepper motor?

Of the various reprap-related projects, MakerBot Cupcake is pretty clearly the easiest to put together. I got mine up and running without much fuss, but I’ve been building things from kits or fabbing things from raw materials for many years. I still needed help from the MakerBot mailing list to sort out a couple of minor problems and I’ve been able to help a couple of other people with their problems.

If you’re primarily a designer, there’s a reason you should consider taking the plunge even if you think you aren’t the sort of person who is ready to build their own 3D printer: self-education.

I’ve learned a lot about fabrication working in the opensource 3D printing world that I was never exposed to using commercial systems. Learning how to use Blender to create models has been painful at times, but I find myself liking it more than Solidworks for simple projects. I’ve learned about bad STL code, the relationships between temperature and speed when laying down plastic, and more about the physical properties of ABS than I ever thought I would need to know. Assembling the MakerBot from parts exposed me to a few neat tricks you can use to make 3D objects out of sheets of acrylic, and some new joining techniques for thin surfaces.

This new knowledge is also helping my ongoing education as a designer. Now that I know some of the printing capabilities, I can change my sketching and ideation process to work around limitations or integrate limitations of the printer. I’ve also rediscovered the old metalworking path of designing a mold to create a basic shape that is finished on machine tools, but instead I’m printing 3D plastic that I can finish using hand tools or machine tools.

It hasn’t been the easiest tool I’ve learned to use, but building and using the MakerBot might be the “funnest” tool I’ve learned to use in recent years.

On the download page is the usual demographic survey, which includes this gem:

Industry:

• Architecture
• Cabinetry
• City Planning
• Civil Engineering
• Computer Consulting
• Construction
• Contractor
• Entertainment
• Facilities Management
• Gaming
• GIS
• Graphic Design
• Hobbyist
• Home Building
• Interior Design
• Landscape Architect
• Marketing
• Mechanical Engineering
• Software
• Survey

First, note the lack of “other”. You are going to tell Google exactly what it is you do or you cannot download the software. How can you have data-driven decision-making when people can weasel out and choose “other”?

Now, note the horrid inconsistency in the hierarchies of the various industries listed and the amount of overlap in some of the categories.. We go from the extremely broad categories of “Entertainment” and “Software” to the very specific discipline of “Cabinetry”. I guess if you’re a furniture designer who doesn’t specialize in “Cabinetry” you’re just an “Interior Design” person. Or maybe “Entertainment”, because people sit on your furniture while being entertained. Isn’t “Gaming” a form of “Entertainment” and “GIS” a type of “Software”?

Of course, the only design disciplines mentioned are “Interior” and “Graphic”, I guess Industrial and Interaction Designers aren’t really designers, they’re “Mechanical engineering” or “Software”. It’s also interesting that the only two design disciplines called out are also the ones commonly (and incorrectly) associated with women designers: interior and graphic.
