Some bits of L3-G0's Innards

I was poking around looking for some of my pictures to show off and couldn't find them, so I've uploaded them to an album on Flickr...

Rose City Comicon

I've been remiss in posting.  L3-G0 has visited a school, Children's Hospital, and a few conventions, and attended a Unicode Technical Committee meeting (last post was backdated).  He's also gotten a new friend, MCK-Y the Lego MSE-6 Mouse (aka Baby Box) droid.

Anyway, here he is at Rose City Comicon.  Roaming the halls we met lots of folks, including Master Chief from Halo!

Hey, Master Chief!

It wasn't as crowded as ECCC, so we were fairly free to roam at will, though we always attracted a crowd.  Some weren't very well behaved though, vandals!

And, of course, there was tons of other cool stuff.  Here L3-G0 poses on the red carpet with a Back to the Future Delorean replica, and a Doctor Who Tardis.

This hexacopter was flying around the celebrity area, Artoo took offence and tried to tell him that it was a no-fly no-camera zone!  (I'm still hoping to find his video of this confrontation).

While we were in the celebrity area, Wil Wheaton took notice.  He was nice.
Garrett Wang was also hilarious on the red carpet.  He saw L3-G0 while talking to a fan and flew over his table to run up to L3-G0 and take his photo.  Startled us terribly.  I heard him apologize to his fans when he went back.
 
Oh, no, L3-G0's lost his head!   We also participated in the R2-D2 Builder's Club talk about building Astromechs, where we showed off some of our droids and how they are built.  It was a talk like this that helped me decide to make L3-G0, lots of folks get there start building by seeing the other droids at a 'con and seeing such a talk.

And we all posed together in the lobby.  Group photo time.

And of course everyone wanted to pose with L3-G0 and the other droids.  I don't think he minds.

It can get quite crowded though....

Things went pretty well this time around, I guess we're getting better at this.  We had two problems: the drive wheels keep slipping on the driveshaft.  The chain turns a sprocket which uses a bolt as an axle, but the set screws (on all 4 shafts, he's 8-wheel drive) keep slipping.  I tried drilling a notch in the shaft for the set screw to grip, and broke the bit.  That seems to have helped the most, having the ground up bit mashed in there to keep it from slipping!  Anyway we had to fix it several times.

I also drove ineptly (again) and mashed a shoulder (same one) into a vendor's table.  The right shoulder's smashed itself 3 times now!!!

The lights died right before seeing Wil Wheaton, so we had to come back for a better pix.

The other problem is an odd electrical thing.  He started freaking out and spraying his mist all the time (he can startle folks with canned air), and his dome started spinning madly.  We'd had a similar problem where the mist freaked out, so we unplugged it.  Then his dome refused to move.  But we thought it was fixed before the con.  Last day we had to leave early though.

When I got home I checked EVERYTHING trying to repro the problem, but it wouldn't happen.  Eventually I replaced the fuse on that circuit (it's the car-type fuses) and he was great.  I left his head spinning for a half hour to prove it.  What happened is that the fuse was apparently weak.  Eventually the dome motor controller got it hot enough that the volts dropped (from resistance), but it didn't blow.  That confused the motor controller which was also reading the RC signals, and sent gibberish to the Arduino controlling the mist, and of course it confused itself about the dome's movement.  What a freaky problem.  What a relief to have figured it out.

We had tons of fun at Rose City Comicon, we'll try to see if we can make it next year!

Emerald City Comicon 2014

L3-G0, a life size Lego R2-D2 attended ECCC (Emerald City Comicon) in 2014.  It took me a bit to get the video and stuff organized, I've been busy, so the post's been delayed.

In case you're new here, as far as I know this is the first time a complete full sized Lego R2-D2 has been displayed in public.  L3-G0's been "out" a couple times (at Microsoft, Lowe's and a Sealug meeting), but not with all his bits.

By completed I mean that as in "just completed."  The last bit got complicated and he didn't show up until nearly the last minute before the doors opened.

We had tons of fun with L3-G0 at Comic Con, here's the aforementioned video:


The video has several short segments I thought showed pretty much the experience, skip ahead if you don't like a piece, the parts get better.
  • L3-G0 with some of the fans taking pictures, even Unikitty!
  • The astromech parade with other Pacific NW R2 Builders Club R2-D2s and other droids.
  • The crowd and going back to "Brick Nation" where the Lego exhibits were.
  • A short encounter with a taller pirate.
  • Darth Lily, one of L3-G0's more enthusiastic fans.
  • L3-G0's shopping spree, it is a con after all, you've gotta buy something!
  • Keeping all those pesky Daleks away from Brick Nation.
People don't seem to be getting past the first bits so I might post individual videos later, however if you want to share only one bit with your friends, YouTube lets you share starting at a certain time.  Or just ask them to skip to 3:57 or whatever.

I forgot to include a bit on packing him up :(  Too bad you can't edit YouTube videos.

Some photos as well:

The ankle details on his right ankle are backwards, fortunately it's hiding in this photo.  I was so mortified when I noticed that a couple weeks after the con.

I liked this nook while waiting for the droid parade.  Reminds me of Jabba's Palace for whatever reason.  (Not saying anyone else would make that jump, but I did).

Made it to Emerald City Comicon (finally)

I'll try to post more later, but here's a tiny bit about the first day at ECCC.  Everyone loved the full size Lego R2-D2.  Asking wonderful things like "do you know about the R2-D2 Builder's Club? (yes)  And then L3-G0 would beep and they'd go "oh, he makes sound too!"  When they started to turn away I'd drive him out and run around the show floor and they'd say "No way, he moves?!?!?!"
L3-G0 was supposed to get set up yesterday, but the skirt took too long to get behaving.  I blogged about what he looked like yesterday morning.  That required 3D printing some bricks and stuff, but I still had time.  Unfortunately the skirt's on the bottom, so he had to be upside down with the legs & feet off to work on the skirt. 
 
When I flipped him back over and stuck on the remaining parts I found little things like the dome wouldn't fit: 
  • Above the shoulders, I'd fixed a gap that was missing last time, he hadn't had that before, so I didn't know it'd cause clearance issues. Because of the tightness I'd left out a plate of thickness, about 1/8" and forgot it'd make the sides 1/8" too narrow.
  • The left battery box hadn't been Kragle'd and tried to disassemble itself when sticking it on.
  • Worst, somehow I'd messed up the center caster.  I knew the standards 3" caster didn't fit in my Lego shell, but my custom casters failed miserably.  But in the trials I found a 3" caster that seemed to work well.  I was so fixated on the fore-aft clearance I forgot about sideways, so he couldn't go backwards without the caster jamming or slamming the box to pieces.  So I gave up on Thursday.  Show didn't open 'til Friday @ 10 so I had time.  I used an early prototype and finally got his feet behaving around midnight.
Getting to the convention center was tricky.  His tie-down is actually really trivial in the minivan.  Jam the front casters into the hold-down for the far back seat (after taking out the seat) and throwing a bungee around it.  Then, with the dome off (sitting on the rear seat), stick the way-back seatbelts around the center post and let them click into being tight.  I'm used to Lego MOCs being fragile and insecure, but L3-G0 travels unbelievably well.
 
Of course that's before putting the fragile shell on it.  I thought I could lift it up, but it turned out there wasn't enough room for the bungee, so the shell came off.  That wasn't too hard, but I outsmarted myself and it was harder to put back on than I'd expected once I got to the convention center.

Once there, the fans loved him.  One seems to have found the droid they were looking for!
 

L3-G0 worked really well.  On the previous trials parts fell off and there were other small problems, like when the shoulder broke.  But he was really reliable.  Unfortunately the battery died before lunch, and I let it get really low, so it wouldn't fast-charge.  Fortunately I found a motorcycle shop that had another.  Alternating two seemed to work fine later in the day (though it's annoying to swap), but we'll see tomorrow. 
 
The worst part was the prodding of the fans.  They liked to poke.  And many wanted pictures with their hand resting on the top of his head.  Which is the most fragile part, so his head was dented a few times.  And he had an accident with his front foot, but for the most part L3-G0 was strong and ran well.
 
At the end of the day the sprockets on the bolts I'm using for axles started slipping :(  The best I can do is probably tighten the set screws in the morning and cross my fingers, but I think it'll be OK.  And maybe slow down the acceleration curve a bit.  It looks like the rest of the stuff I did to tighten up the wheels worked OK though, so it should be solvable.
 
Gotta get over to the R2-D2 Builder's Club folks sometime, which should be tricky as they're in the other building, and worse, on the other side of the trade floor.  The alternate route crosses the street and L3-G0 hates pavement (way, way, way too bumpy).
 
Need sleep, two nights up way too late.

Latest Video

Still needs legs and a few other details, but lights and sound are working now!  He went on another test run at work (Microsoft Building 50).  Afterward we took a spin through the cafĂ© where he got quite a few pictures taken.
