Can you tell I’m trying not to work?

I’ve been sick the last few days.  Yesterday I thought I was feeling pretty good and ran a bunch of errands.  By the time I got back home and took care of a few small projects around the house…  I was totally wiped.  It felt like someone had just pulled the plug on me.  Obviously, although I’ve been as weak as a kitten, I’ve been posting all kinds of nonsense. 1

DrawBot – Printed Parts

So far I’ve got three types of printed parts:

  1. Spools
    1. These spools hold the monofilament and are friction fit onto the motor shaft.  You can check out the designs on Thingiverse.
  2. Motor Mounts
    1. The Thingiverse page actually has a lot of information about the motor mounts.  They’re designed in OpenSCAD and are mostly parametric.  Since I’m mounting these motors inside a box, the mounts are designed to go into the corners of the box.
  3. John Abella’s Gondola
    1. I haven’t hooked everything up yet, so I don’t know how well this will work.  I can’t wait to find out!
  4. Arduino Mount
    1. I’m kicking around some ideas for how this would work.  Ideally, I’ll end up designing a bracket that the Arduino and motor shield can just snap into.

DrawBot – The Assembly, Part VI

Okay!  It was a good day for drawing robots in the MakerBlock household!  Here’s what we got accomplished:

  • I designed some motor mounts, printed one… and had to redesign it.  Gotta love having a 3D printer!
  • I selected a long shallow pine box to hold the motors and electronics.
  • I tried a variety of sound insulating materials.  Bubble wrap was easily the most effective, but least practical.  I settled on some corrugated cardboard.  I placed some cardboard between the motor and the motor mount and between the motor mount and the wood.
  • I soldered some longer wires to the motor leads.
  • I drilled holes in the wooden box, attached some monofilament line to the spools, put the spools on the motors, mounted the motors, ran the leads to the Arduino, powered it up… and it moved around and stuff!

As this point the next step is to mount it on the wall and actually attempt to draw stuff.  Yay!

Simple Series – Half-Life; Market Research

I’m wondering at what point will the downloads on this plugin plateau.  Whatever the eventual baseline download rate, I would suspect that speaks to the amount of maximum market share that is possible for a plugin that performs these functions.1  I would think that downloads would spike when I release a new version of the plugin.  Given that I released about five updates to this plugin the first day, I would assume some of those initial downloads were duplicative.

As far as rankings go, at this time this plugin is #5 on WordPress.org’s plugin search page, #5 inside WordPress’s internal “Add New” plugins search page, and no where to be seen in the Google rankings.  Looking at Google Keywords, it appears that there’s no small amount of search traffic for the keywords “WordPress series.”  There’s some 200,000 global monthly searches.  One of the reasons I’m following this so closely is that I’ve had a few ideas for plugins that I could sell.2

Here’s the WordPress.org plugin download stats for “Simple Series with SEO!” for the first four days.

  1. 1/26/2012: 1 download
  2. 1/27/2012: 99 downloads
  3. 1/28/2012: 37 downloads
  4. 1/29/2012: 20 downloads

What will tomorrow bring?

TARDIS’s are more practical than you might think…

You could use a prop TARDIS for a tool shed, chicken coop, garden shed, file cabinet, etc.1

But, as I was watching that video of Sillysparrowness build her TARDIS, I couldn’t help thinking…  This is a time and relative dimensions in space device – why does it need to be enclosed?  As long as you are going to use it as a prop, rather than as a storage device of some sort, you would really only need the front, the left or right panel, and the top.  Admittedly, then you could only take front or 3/4 perspective view shots.  If it were modular, the left and right sides could be swapped back and forth so you could take a left or right-sided 3/4 view picture.

If constructed in such a fashion it wouldn’t take up much room if you were to put it facing into a corner.2

Anti-Virals

Here’s the WordPress.org plugin download stats for “Simple Series with SEO!” for the first three days.

  1. 1/26/2012: 1 download1
  2. 1/27/2012: 99 downloads2
  3. 1/28/2012: 37 downloads3

It looks after being bumped from the newest plugins slot, the downloads dropped precipitously.  So much for going viral, money, and fame, eh?

Actually, I’m happy to have helped out a 100 people or so.  I also think a lot more people will end up using this plugin over time.  The alternatives, while very good, are more difficult to use and do tend to add a lot of other stuff into your WordPress installation.

DrawBot – The Assembly, Part V

I just finished soldering the Adafruit Motor Shield … this time with all the bits in the correct places.  The Adafruit directions are incredibly detailed, I just soldered a few parts in wrong like an idiot last time. This time it went much smoother and much quicker.

I just wired up the two steppers, plugged in the power adapter, plugged in the USB cable, uploaded the Polargraph firmware, fired up the Polargraph software, and asked it to try to draw something.  And it started to twitch away in what appeared to be a meaningful pattern!!!

Huzzah!

Now… for sleep!

DrawBot – The Delivery, Part VI

Okay, that was FAST.  I ordered the Adafruit motor shield from MakerBot on 1/26/2012 just after midnight and it arrived today a little after noon.  That’s about two-and-a-half days for the parts to be packed, shipped, make it from Brooklyn, NY to Oakland, CA and then to my secret robot lair in the Bay Area.1  While at the hardware store today I picked up some small eyescrews and new tips for my soldering iron.  Tonight I’ll assemble the board.  Again.

I can honestly say that I was mightily tempted to purchase a third motor shield along with this second.  However, as I have no immediate designs on a secondary DrawBot2 I’m not ready to admit the possibility of defeat.  In the words of Kongorilla, I will not fail.3

Actually, now that I’ve got these new soldering iron tips, I stand a chance of being able to desolder the mis-soldered parts. 4 My old soldering tips were old, tarnished, and somewhat crusty.  The soldering tip I’m replacing is all of these things plus it is in the rough shape of a flathead screwdriver. 56

Wish me luck!

  3. Actually, that’s a little more bravado than I’m really capable of.  If I fail, I fail – I just have no intention of ending at failure.  Rather, I’m committing to repeated failures … until I end up with a working DrawBot [↩]

I had a dream last night

One of my favorite songs has this line in it, so I just like saying and writing it.  So much so that I’ve used that same exact title for three posts, including this one.

Okay, so, in this dream a huge package arrived from MakerBot.  It contained a bunch of spools different colored plastics, a brand-spanking new Replicator, and a galvanized steel industrial strength sewing machine as big as a saw horse.  I’ve never seen a sewing machine that big, so it was entirely an invention of my mind.  And, now that I think about it, I don’t even know how it would even work.  I recall thinking, in my dream, that the thing was strong enough to sew a stack of denim jeans together.

Um, there’s not much else to this post.  I suppose the dream was probably about my excitement over a new delivery from MakerBot so I can finish my DrawBot and the prospect of getting a Replicator one day. 1

  1. I think now that we have two 3D printing robots, Bender the Cupcake CNC and Flexo the Thing-O-Matic, an Egg-Bot, and I’m in the process of building a drawing robot my wife has caved to the sense of inevitability that whatever new robot MakerBot produces I will buy. [↩]
