No RPM

orange

I had a blast doing the RPM Challenge last year (and if you don’t know, the RPM Challenge is to record an entire album in one month, during February, to be exact.

Here’s a little history: in 2008 I completed the challenge, then did it again in 2009. In 2010 I didn’t manage to do it, but I came back in 2011 and did it again.

Watching the progression throughout the years has been really interesting for me, and I’m glad it did it each time, and blogged about it each time, but for 2012, I’m taking another hiatus, and I’ll plan on jumping in again for 2013. I’ve got a lot going on right now, and too many unfinished projects to consider starting another one, especially one that will put the others on hold. I’m also speaking at a class, teaching a class, traveling out of state, and have a few other things scheduled for February that have convinced me to scale back my commitments.

If you’re interested in all my posts about my past RPM Challege adventures, just browse the rpmchallenge tag.

See ya next year kids!

CNC Control Panel Progress

It’s a known problem that I take on too many projects, and that tends to make some of them drag out longer than they should… has it really been more than a month since I started this one?

Yes it has. In my UI Mockup/Diagram Apps post, I was working on a control panel for the CNC Router we have at the Milwaukee Makerspace.

First Attempt

The image above was my first attempt to hack something together. I wanted to do a layout with paper to get a good idea of the physical size of things. As you may notice, the buttons are big, and make the whole thing fairly large. Larger than I wanted. So through a few posts I connected with a fellow maker in Madison who offered me some smaller buttons…

Control Panel

Once I had the smaller buttons, I sat down with some paper and the calipers, and started measuring things, and making the new layout. These were, like the previous attempt, just some rough sketches on paper. Once my paper sketches were done, I moved on to Inkscape, and made the digital version of my control panel.

Paper Mockups

I then went back to paper, by printing out my files, to get a feel for the size and spacing of everything. I didn’t go as far as mocking up an actual 3D model, though it would have been easy with some foamcore or matte board, but it’s one more step to take if needed.

Cut Panel

And as long as I was at the makerspace for some laser-related shenanigans, I figured I’d cut a test of the control panel using acrylic. (I’d like the final done in wood, but I had some scrap clear acrylic on hand, and it’s easier/faster to cut than wood.)

As is often the case, I screwed up one bit of the file, and the lower-left cut is too large. The two holes on the right are waiting for buttons I don’t have yet. Right, make that: buttons I didn’t have yet. More buttons showed up, but they are slightly smaller, so I’ll meed to re-size things again before the next cut. Back to the old drawing application, as they say.

And hey, I better finish this project soon, because there’s talk of adding a 4th and 5th axis to the router! I don’t really mind though, because so far I’ve really enjoyed the process, and I’ve learned a lot along the way, so even if this thing is outdated by the time I finish it, I’ll just start on an upgrade. :)

Laser. Cut. Files. (Part II)

NOTE: See the latest post on this subject: Laser. Cut. Files. (Part III)

In our last adventure, Laser. Cut. Files. I thought I had it down… sadly, I was wrong, and I’ve actually updated that post, and here’s a Part II to share more of what I’ve learned.

Inkscape DXF

This time I once again started with Inkscape, which creates SVG files. From there I export to a DXF file. This is, I guess, not ideal, but it sort of (mostly) works, so I’m still trying to perfect it. Mostly.

The issue I mentioned last time involved exporting a DXF file from Inkscape and then not being able to re-open or import that DXF back into Inkscape. I’d get some weird error, which I thought might be due to too much extension madness in Inkscape. Anyway, I ended up re-installing Inkscape and now I can open DXF files, but they just show up blank, so that’s not much better.

I did however finally find an application for OS X that allows me to easily open and view DXF files: SolidWorks eDrawings. This should help me see what crazy stuff happens to my DXF files between Inkscape on the Mac, and CorelDraw (yuk) on the Laser Cutter.

Here’s my most recent file loaded into SolidWorks eDrawings.

DXF File

Hey, look at that! I can view a DXF file on my Mac! And it was much easier than last time, where I screwed around with OpenSCAD to do it.

DXF File

But wait… as we zoom in, we can see that when the original Inkscape SVG file was exported as a DXF, it did that crazy thing again where it changes curves into lines! (Argh! I know that there are times when you want this for CNC things, but this isn’t one of them… and if I wanted them, I could do it myself. In fact… maybe I’ll just start doing it myself if I have to.)

For this control panel, it didn’t really matter, since the front of the button will be covering up the hole, but I’m still not happy with the results… And just so we’re clear, the results I want involve me doing the digital design in tools I can run on my Mac (that I like using) and then getting those files onto the laser cutter PC with minimal screwing around, and just doing my lazzoring.

A simple, clean, friction-free, non-annoying process that doesn’t involved having to mess around redrawing things in CorelDraw (yuk) because really, it seems like it shouldn’t be this hard.

Oh, and as for the Laser Cutter PC, Inkscape got installed, but I couldn’t get it to work with the Laser Cutter. Illustrator 8 was also installed, which can’t read SVG files, and couldn’t open my DXF files either. So sadly, for now, it’s that damn CorelDraw…. yuk.

CPAP Progress

CPAP

Back in November of last year I did a sleep study, and as expected, I’ve got sleep apnea, so I ended up getting a CPAP machine at the beginning of December. Since it’s been a little over a month of using it, I thought I’d write up the experience so far…

The first week or so was a bit rough… besides getting used to the mask, I was experiencing terrible dry mouth. The dry mouth issue was due to the fact that we keep it pretty cold in our bedroom (we use a heated blanket) and the nurse I met with told me they would ship me a special heated hose which would help with the dryness. Getting the hose took over a week due to a few mix-ups, but once I got it, things were much better.

Let me just say right now… I never knew I could sleep so good.

For pretty much my entire adult life, I got terrible sleep. When I was younger, it didn’t bother me that much, but it’s gotten worse and worse in recent years. Besides not getting enough sleep myself, I’ve annoyed the crap out of my wife with my snoring. So while I wasn’t sleeping well, neither was she. In the past year both of us have taken turns on the couch just so we’d both be able to get some sleep.

So… the good sleep. Finally, some good, solid sleep. Before the CPAP, I could have “slept” for 8+ hours, and still gotten out of bed completely exhausted, but as it is now, I can sleep 6 hours, and wake up knowing that I can get through the day without falling asleep or even getting drowsy. I’m awake, alert, and more engaged. I even dream now! For years I didn’t dream much, due to the fact that I never got into REM sleep. That’s changed as well, and I’m dreaming quite a bit now.

But it’s not all sleepy dreams and happiness. Even though I’m getting good sleep, my wife is still struggling with my amazing new ability to sleep. Here’s where I get into the bad parts of the CPAP.

You might thing that the CPAP machine itself is noisy, but it’s really very quiet, so that noise isn’t an issue, but what is an issue is the mask I wear. To put it on requires two snaps. “Click! Click!” goes the mask when I put it on. So if I get in bed later than her, I’m making noise. If I go to the bathroom in the middle of the night, I need to remove the mask, and then put it back on, so I’m making noise. Alternately, I can keep the mask on, but remove the hose, and that goes “Snap!” when it attaches. More noise… But wait! There’s also the Velcro adjustment straps. “Rip! Rip! Rip! Rip!” if I need to adjust for air leaks. As for the machine, well, the power button makes a “Click!” though not as loud as the mask, and the LED display is bright enough to light up the room, so I keep it covered with a piece of fabric.

All in all, I’d love to see some improvements in the silencing of the whole process… but ignoring all that, it’s still pretty damn sweet.

Wearing the mask can be annoying, but when I think of the alternative, I’d prefer to wear the mask and actually get some sleep.

Oh, I also talked to one person who said it freaked them out, and they were worried that the power might go out and they wouldn’t be able to breathe and… It doesn’t work that way. CPAP is “continuous positive airway pressure” not a respirator. You can keep breathing (and stay alive!) even if it shuts off.

And yeah, the mask isn’t fun like a Halloween mask, but like I said, it’s worth it for the change its made in my life.

Thanks Mr. CPAP!

MakerBot Marketing

MakerBot Industries

I meant to write this post about a month ago, but writing it now just validates the points I was going to make anyway, so read on!

Back when I wrote 3D Printing is the Future, I mentioned a number of companies, including MakerGear, Ultimaker, and of course MakerBot Industries. Four months later, I’m going to update my thoughts on them, and specifically focus on what the MakerBot folks do in the area of marketing.

Wait… Marketing? If you read the piece in Fast Company you’d know that MakerBot Industries doesn’t do marketing:

… When I speak with MakerBot’s Keith Ozar, he seems offended when I refer to such undertakings as “marketing.” His background is in underground music promotion, and he joined MakerBot when the company advertised a “marketing experimenter” position in early 2011. MakerBot doesn’t really market at all, he counters; it actively participates in the community the company seeks to both cultivate and create, involving “people who are creative, people with imaginations.” That means a presence at Maker Faire-style events, where hardware hackers congregate, and more recently at comics conventions and the like.

Here’s where I haul out the disclaimer: I work at a marketing company. I also market myself, and the things I do. Almost everyone does, even if they don’t call it marketing. If MakerBot doesn’t want to call it “marketing” I’m fine with that, but let’s be honest, that’s what it is.

With that out of the way, let’s look at the marketing that MakerBot does…

MakerBot Web Site

MakerBot has a web site. Hmmm, that’s nothing special. Let me rephrase that: MakerBot has a good web site. Their web site clean, well designed, and organized. There’s a store, there’s info on the community, including links to User Groups, Twitter, Flickr, Google Groups, etc. as well as a link to Thingiverse. Their support page has a lot of links to their wiki, and then there’s the blog.

The MakerBot blog isn’t just some “look at me!” thing where they talk about themselves (though it has been a lot of that lately, due to the recently launched MakerBot Replicator.) The blog also highlights things that members of the community are doing/making. And the blog is updated very often. Very often. That’s key.

Ultimaker

When the Ultimaker came out I heard a lot of talk about how much better it was than the Thing-O-Matic, and it may be better, but take a look at the Ultimaker web site. It just looks like a blog, and as of my writing this, it’s been over a month since it’s been updated. And before that it was a month and a half. I know blogging takes time, but for a small company it can get you the most bang for your buck when trying to tell people about your product.

MakerGear

In the world of RepRap, reprap.org is packed full of information, but if you want to buy a RepRap kit, MakerGear is a pretty well known and respected seller of the Prusa Mendel kit. They also recently came out with the MakerGear Mosaic, which is their own design, and is a capable machine from all I’ve read.

Visit the MakerGear web site and let me know what gets your attention… if anything does. There is a “What’s New?” link on the home page, that links to a page with a post that was written nearly two months ago. (With a typo in the title.) I’m a MakerGear customer, and I think they’re a good company, but I wish things looked a bit more professional. For a first timer visiting their web site (or the Ultimaker site) I don’t think they’re going to be impressed.

But then, maybe these companies don’t want to impress people. Maybe they’re only targeting the alpha nerds, who know the inside scoop, and think that MakerBot is for people who don’t know better, and the real desire is for servicing a niche market. If that’s the case, then that’s fine… I honestly don’t know.

So besides the web site, what is the “MakerBot Marketing” you ask? I’ll just throw a few things out there.

MakerBot: has good photography, has good videos (including MakerBot TV), they have a curriculum for schools, are behind Thingiverse, they’ve implemented an Artist in Residence program, did the Project Shellter thing, scanned people’s heads, and on and on.

Some of those things take a bit of money, which smaller companies may not have, but there’s no shortage of clever ideas, some of which are relatively cheap, and if it gets people talking about you, isn’t that what you want?

So yeah, MakerBot Industries does marketing, and it may be marketing on their own terms, and in their own way, but in the end, if people find out about you, and keep hearing about you, that’s building your brand, and that’s worth a hell of a lot.

Here’s the thing: You can have the greatest product in the world, but if no one knows about it, you won’t have any customers, and no customers equals no business, so marketing is important… even for nerdy 3D printer companies.

(Oh, there’s one more thing that’s key to MakerBot’s marketing effort, which I’ll probably talk about in another post.)
