Maker Faire Day 1

So we made it though our first day of Maker Faire. It was insane how many people were there. We quickly realized we had a lot to learn! People loved the 3D models of the claw game and got such a kick out of seeing the giant claw move. Sadly the machine was broken 50% of the time. All the dust was ruining the belts and end stops. We even broke the u joint for the controller three times, sparks were flying, literally, as we grinded parts back into shape. We’re really sad we barely got any time to visit the other stands since we were repairing so much.

We’re 25% of the way to recouping the cost of the machine, hopefully we kicked most of the kinks out of it. The motors are starting to act funny, so signs are pointing to some catastrophic failure midday tomorrow. Get there early if you’re still interested in playing. We’ve changed the rules so it’s gonna be even more fun.

Also Wii Raffle holders, your chances of winning are 1 in 40 as of Sept 25th 11:24 pm. Be sure to check back here on Monday the 27th when we announce the winner.

The Mega Claw – Maker Faire (8 of 9)

The Night Before Maker Faire

‘Twas the night before Maker Faire, when all through the house
Not a motor was spinning, not even gauss;
The sensors were mounted, on the joystick with care,
In hopes that Bre Pettis soon would be there;
The engineers were nestled all snug in their beds,
Whiles visions of tesla coils buzzed in their heads;
The prizes were ready, some were wizard caps,
Some were inflatables, but none are pure crap.

Happy Maker Faire!

The Mega Claw – Prizes (7 of 9)

So what kind of prizes does a massive claw machine have? Well we all chipped in and bought over $700 in prizes for Maker Faire. All the earnings will be used to power Splitreaction’s web fees, projects and cost of the machine. We certainly like the prizes. We hope you guys will too! Also since we hate unfair claw machines, the MEGA CLAW will be a PRIZE EVERY TIME!

The Mega Claw – Electronics & Software (6 of 9)

HARDWARE

This is the block diagram, some of the things may have changed since we first worked with it. The Mega Claw is an Arduino Pro Mini with some Sabertooth Motor Controllers and a PC communicating over serial.

The Mega Claw – The Frame, Sliders and Prize Bin (5 of 9)

THE FRAME

For the frame of the Mega Claw we figured we would start with a regular canopy. It was affordable and much more portable than the original one we started working with. In this segment We’ll talk more about how the main structure was put together and why it was designed that way.

The Mega Claw – Joystick (4 of 9)

The joystick was a definite must.  We had talked about it and stumbled across Mary Flanagan’s giant joystick and it was final, we needed something epic. Just like her’s, ours is modeled after the Atari days of joysticks. It’s human sized and enough to be a project itself. We’re hoping that we’ll be able to use this to play games as well.

The Mega Claw – Claaaaw (3 of 9)

So I designed the real claw in Google Sketchup, a 3d design tool. I decided to make it out of 1/4in plywood and to add a skate bearing at every joint to reduce any friction or strain on the motor. In hindsight this cost a lot more and probably wasn’t necessary. Continue reading ‘The Mega Claw – Claaaaw (3 of 9)’

The Mega Claw – Concepts and Experiments (2 of 9)

Here’s a little sketch of the original idea for the Mega Claw. Build a big frame, make a slide go back and forth left and right and drop a claw. Easy right?
