Rubber Sole

Despite the way this starts, this is NOT a shoe review.

I have spent this summer wearing a pair of Blackspot Unswoosher V2 shoes. Since the mid 90s, I have been a fan of John Fluvog’s shoe design. When I found out that he designed an “unbranded” pair of shoes that were to be manufactured in a sustainable, labor friendly way, I had to check them out. Here’s a glimpse at my Unswooshers:

There are only two kinds of men’s shoes in this world: those that can be re-soled and those that can’t. I detest companies that charge a lot of money for shoes that don’t have a mid-sole and therefore can not be re-soled (Steve Madden, for example). I pronate (put my weight on the outside of my foot when I walk) and with my 200-ish lbs, I can wreck poorly made shoes in less than 2 months.

The Unswoosher not only had a mid-sole but it has recycled tire soles. I’m not talking about what Timberland is doing where they are mixing the existing rubber with some virgin rubber and being molded into a conventional looking sole. The shoe has treads and it is awesome.

Turns out, even more important that knowing that come this winter I will leave the coolest looking tracks in the Denver snow, the soles show NO wear after 2 months of consistent wear. Apparently, me weighing a good deal less than a car has something to do with it.

So what do I take away from this? Colorado has 1/3 of the nation’s scrap tires. I understand that it takes work to separate the tread of the tire from the steel bands (unless you’re a late 90s Ford Explorer). Still, there is a tremendous resource here. What is insufficient tread depth for a car is more than sufficient for a person. Car tire soles could easily be offered as an option for when shoes get re-soled. I would love for my 12+ year old Frye boots to get tire soles the next (3rd) time they get soles.

I can not find a company that is doing this as an option for the repair market. Someone should. Let me know if you have more info about this.

Heart Mod

Suddenly I regret that I’m donating a coffee table. Had the project been a chair, the title could have been about “chairity” and I could have dies happy. Oh well, I’ll have to continue to plug along, I guess.

Anyhow, what you’re looking at is the “Heart Mod.” It’s a version of the Mod coffee table that I give away on this site that has a heart cut into it? Why you ask? I’m donating it to the Colorado AIGA (16th Annual) 2010 Heart Art auction. Part of the money benefits AIGA, but more importantly, half goes to Project Angelheart, who provide nutritious meals to people with life-threatening illness.

The Heart Mod is made from FSC certified 3/4″ bamboo plywood. It still needs its low-VOC finish and to have the edges knocked down. The CNC cutting time was generously donated by the Industrial Design department at Metropolitan State College of Denver. Thanks for Terry Dreher for doing the cutting and Ken Phillips for making the call to donate the table time.

One of the cool things about the Mod is that it assembles without hardware or glue and it packs flat. It’s one of the first products that will be available from my future (next month or so) online retail outfit.

Make sure if you’re in Denver to come to the event. And then bring lot’s of dough to buy yourself one awesome table.

my wallet hurts

This post is largely my apology for ignoring this site for a little while. I’ve been busing selling limbs to pay for some computer upgrades. I’m not down to 1 arm, one leg, and a single kidney (metaphorically).

Graduating is expensive. I’ve been sort of floating along until my student Solidworks license expired. It did. Oh boy, did this last week brought some expenses. I’ve now purchased a proper Solidworks license and am a subscriber. I decided to take the difference in moving to a Solidworks Professional package and invest that in some render nodes for Maxwell Render. I’ll let you know how that works out.

I’ve ordered the hardware for the nodes. They’re 2 i7-860 2.8 Ghz quad-core processors with the appropriate motherboards and CPU coolers to overclock them. So basically, right now at least, I’m going with two more computers along side my MacBook Pro. The funny part is that the render nodes will be actually faster than my main computer… just not as pretty. I am adding the cheapest Solidworks certified card to one of the nodes so that I can do my work on it if I so choose.

All in all, total for 2 very fast computers without monitors or keyboards came to about $1700. I spent a while calculating the cost of making 3 machines with Core 2 Quad processors or 2 machines with the i7s. Everything pointed to going with the two i7 because the hyper threading ability apparently makes a good difference when rendering.

I’ll be excited to share my results.

Also on the slate for last week: clean installs of Mac OSX and Windows 7 on the MacBook Pro. This was precipitated by the installation of a 500GB (7200 rpm) hard drive. It was time to move up from the 250GB (5400 rpm) drive that was in it. Fortunately, drives are getting cheap, even in the 2.5″ size.

Competitive 3D Print

This Year’s IDSA National Conference is themed DIY: Threat or Opportunity.

Seriously? Wasn’t the time for this about 4 years ago when talking about it could have actually made a difference in how things played out? We’re already at the “DIY: how to stay in business by not sucking” point. The answer to IDSA’s question is already here. DIY is absolutely an opportunity for anyone who is excited about the new technologies available to us and wants to experience what it’s like to help shape the future. It is only a threat to those interested in maintaining antiquated systems for getting ideas to users. If you like how things have been for the last 20 years (I know, it’s longer, but how much is open to interpretation), well, tough cookies. The good news is that you won’t be in business much longer anyway, so you won’t have to worry about what happens after that.

Ok. I’m coming off a little strong about it. And the changes won’t be overnight, but they are coming. And it’s a good thing. $3000 just became the entry price for a competitive 3D printer. I no longer need injection molding to get a plastic part run off. And now I don’t have to over-produce to hit a price point per item. Is there still opportunity for designers here? Oh, yeah. Now more than ever. Any of us with a good (or bad) design can get a product to market. The designers should have the advantage. We should be able to get better products to the market. If there’s a demand for it, it is risk free to move to a larger production run.

Tad Toulis told me this weekend that there is a kid in China that has an Alias seat and can do what I can do without my fancy schmancy degree. Sadly, I’m pretty sure it’s true. One of the biggest differences between a designer and an amateur is practice. Technology is getting cheaper and that means that the access to the equipment and tech to “practice” is becoming widespread. So what to do?

Figure out how to do more than draw pretty pictures. Don’t depend on the history of design to keep you employed, depend on your skills to keep you employed. Figure out how the new technologies are changing things and put yourself at the front of the industry. Or keep designing plastic trinkets for injection molding until you’re out of a job. Your call.

Pleasant Surprise

Groggily, I stumbled into my home office this morning and was confused by the number of inquiries I had from Etsy users about The Mod. Then Rasberry, my lovely wife, insisted that I take a look at the Etsy finds email. It clicked. Well, mostly. It took a little longer that I’d like to admit for me to put two and two together.

The Etsy Gods saw fit to include The Mod in their email. This is very nice. Anyhow, to see the actual mailer that went out, click here.

It’s a good way to start out a day. It made up for the tequillla headache that I probably shouldn’t talk about on this supposedly professional site.
