Maker Faire Upgrades

Maker Faire is just a day away, and I’ve had a busy time getting ready. This is probably my favorite event of the year, and we will have a good showing, with 4 droids and 6 builders in attendance. Bonnie Burton from SW.com will also be there running a kids workshop on Star Wars Puppet Craft.

Over the long Memorial Day weekend I stripped Artoo down for some long needed repairs and upgrades I’d been putting off.

I’ve replaced the center foot with the a new one from JAG with the taller skirt. Here’s a comparison shot with the new foot on the right

Sadly, with extra tapper of the foot skirt, the “Special” 3 inch Ace casters are too big and had to be re-worked. To be honest, they were a bit of a squeeze in the old foot, so I was on the hunt for some nice 2.5″ casters! I searched and searched locally, but couldn’t find anything suitable, I had three options, order something online, hack what I had, or just install one caster.

Long story short, I tried the last option, and even went as far as creating a new mounting bracket for one 3″ caster, but when I was done I then had to redo my ankle locks as there was now a backward tipping as well as the forward tipping. Hard to explain, but bottom inline I needed to redo my locks, which meant drilling more holes in the ankle that I wasn’t prepared to do….. back to the drawing board.

Because of time, and on Gerard’s suggestion, I resorted to trimming down the 3″ casters I already had. I mounted them in my drill press and filled them down.  It took forever, there was rubber dust everywhere, and it’s not something I want to do again.

What I’ve also realized is that never trust a label, the original casters were labeled 3 inches, but they were closer to 2 7/8th. Here’s a before and after comparison

After some finegaling, and making a new mounting plate,  I got them installed in the new foot – nice and level, unlike when I had the 3″ wheels.

Getting the right caster for the center foot can be tricky, it’s a balancing acts. You want the biggest wheel you can get fit, but because space is tight, the deeper you recess them to get things level the less space you have for a bigger wheel.

oh! and just as I was done with trimming the wheels, I went back and looked at one of the online stores I’d found earlier in the weekend, and what do I find – they’re LOCAL, or almost. They’re called California Caster and based in San Francisco, and had 100’s if not 1000’s of caster products in stock. I just had to make a trip up there. This was just a small selection of casters they had on display

Even though my new center foot was running again, I picked up these replacement 2.5″ wheel for the next round of maintenance.

I also replaced the radar eye with one I picked up from Dave Shaw many moons ago, luckily the old hole placement didn’t screw anything up. It doesn’t look too much different, and the wife thinks I’m crazy for swapping it out. I had the hardest time matching the Kryder blue, and it’s way to clean, but none of my panels match anyway 🙂

I can’t remember exactly what else I worked on, this was my droid on Sunday morning, all stripped down.

There’s been a long list of things I wanted to re-work, like shortening and re-routing some wires that were bugging me, to tweaking the front vents. I almost added servos to the utility arms, but that would require me filling them down and repaint – which I didn’t have time for.

But I did hinge manage to hing some doors in the body. I made some little aluminum brackets to help mount the servos to the frame

I know I worked on more stuff for Makers, but I can’t remember exactly what 🙂

oh! I remember, I’ve also been working on a small wireless controller based on a iPAQ Mobile phone, but more on that later.

Maker Faire Coming Soon

The fourth annual Maker Faire is just around the corner (May 30th), it will showcase individual creativity and grassroots innovation in the largest festival devoted to DIY culture and technology in the country. We’re hoping to be there again with our droids, if you’re interested in joinng us drop me an email.

It’s kind of hard to describe the event, but PC Magazine put it pretty well “Maker Faire is an improbable mixture of spectacle and practicality–a combination of engineering, crafts, science, and art that seemed to sufficiently blur the lines between all four.”

My Artoo in Bantha Tracks

I almost forgot to post this, my Artoo is in the September 2008 edition of Star Wars Insider / Bantha Tracks.

The photo was taken at the Maker Faire back in May.
