Having Fun at BrickCon 2015!

L3-G0 and I went to BrickCon again this year.  (Ok, I've been bad and not posted about others).  I thought I'd share a few pix.

That Artoo Unit keeps trying to shove me out of the picture!
I went out to entertain the crowd a bit outside the hall in Seattle.  Here I'm showing off my off-road skills by walking on water!  Let's see L3-G0 do that!

Unfortunately I got a bit excited trying to run away from that toddler that looked like they wanted to eat me.... or maybe just hug me... and encountered a brick wall.

Is that what they mean by "Brick" Con?
I had to take a break after a bit and relax away from the crowds.  Here I am with a local landmark.

My cohort also won an award.  "People's Choice" they say.  Why do they always pick the Astromech?  Why not the smaller bots that are the workhorses of the galaxy?  Anyway, congratulations L3-G0!

Getting Ready for Emerald City Comicon (ECCC)

Aiiii, not long before ECCC and MCK-Y the Lego Mouse Droid is having challenges. At Brickcon his paws pretty much fell off in the last hour. So they need fixed. His sound also had a horrid ground loop feedback thing going on. And lastly his ground effect lighting is cool, but it needed more!

So MCK-Y the Mouse Droid was torn apart, and of course when a cat sees a mouse, he wants to help out.

First order of business was getting the lights replaced.
MCK-Y's LED Light Board
As you can see, the back wheels are missing and MCK-Y's pretty much demolished.  He's heavy, almost 1/3 as much as L3-G0, so normal RC/Lego tires won't cut it.  For Brickcon we filled them full of beans, and then when the beans ground down, we ran to the store and bought split peas.  That gives him an interesting gait, but doesn't work great.

I thought of foaming the tires, and this is what happened.
Lego Tires Imploded After Spray Foam
Ick!  When we release the vacuum, there was a pile of gooey resin. For the rear tires we sprayed again and left an air space, which mostly worked.  For the front tires that also failed, so we ended up drilling air holes in the wheel and then using silicone caulk.  Something reacted with the uncured resin and the silicon exploded, but now they're nice and firm.

You'll notice that the tires and wheels are normal Lego parts.  They're attached to 3D printed hubs that are on the normal car axles.  The front wheels are attached with normal Lego Technic pins, though the rear wheels got #4 screws through the middle of the hubs to press them into their spot (at Brickcon they fell off several times, hopefully this will help).

Now he's getting close to back together.  Only a few days to Emerald City Comicon (ECCC), hope to see you there.

Whew, made it to Brickcon! - MCK-Y the Lego Mouse Droid

We should probably write a little more later, but I wanted to make sure there was at least a decent picture of MCK-Y the Lego Mouse Droid.  (My friend L3-G0 is in the background)
 
This was after a couple days of running around and getting tired in general.  There's even a missing brick (not sure if you can find it ).  My builder's promised she'll replace it.  Soon I hope.

MCK-Y "Picture Frame" Test (Lego Mouse Droid)

Some video https://www.youtube.com/watch?v=_0qOqexU3LU (it's not that exciting, and the YouTube channel isn't pretty yet). But the chassis works and drives!



...at least until the wheels fall off.

It sort of needs an RC chassis (it's a bit much for Lego Mindstorms, though it could probably be done, but we'd have sound and other problems that rule out Mindstorms).

To try to keep it looking Lego, we mounted Lego wheels onto the RC axles, by printing hubs. The printed hubs also get the right widths. Unfortunately our pins aren't secure enough. We know how to fix that (different pins, and maybe Kragle), but for the moment it's odd.

Had a fit with the electronics. They're being hyper, but I overcame the last hurdle, so now it's just a matter of shoving them on the board.

Supposed to get to Brickcon on Friday....  Hmmm....

What do we build next?

Now that we've built L3-G0, what do we do next?

How about a Lego MSE-6 "Mouse" Droid?  (You know, the one Chewie scared on the Death Star). 

Here's the thinking so far:

He'll be a lot smaller than L3-G0, about 2000 bricks.  Lara's doing most of the building, Shawn's looking at electronics.
