Introduction: Portal 2 Clock on a Budget
With my best friend's birthday looming and an ever-restrictive poverty class budget being enforced by my loving and beautiful wife, I faced a bit of a problem. He and I had been joking for months about building a prop from Portal 2 (mostly hoping for a Space Core), but my budget and time just weren't there.
Presenting the learning experience that followed: The $30 PotatOS clock.
I knew I'd never be able to make this completely accurate to the game model with my limited skillset and materials, so I set out instead to find parts that could approximate the general idea.
Key to this project were:
Foam and tools to shape it (I used a fine floral styrofoam)
16 gauge primary wire
A small mailbox reflector (orange, obviously)
A PVC nut and washer from the plumbing section at Walmart
A clock movement
Additional scrap foam
Step 1: Pattern Time!
Take a marker and get a feel for the shape of your potato. Then start carving!
Step 2: Figuring Things Out
Here, I started assembling the eye/brain portion and figuring out how it would translate into a clock. Eventually I realized that I would need to carve an additional window into the "potato" to help house the clock movement.
Step 3: Details, Details.
Finish assembling your clock movement, and get ready to get dirty.
Painting foam is a chore, and I considered multiple ways to go about it (such as plaster bandage coating, papier mache, etc), but in the end I found a nice protective coating that could be layered onto foam shapes and dried overnight.
Collecting two shades of brown, sponge brushes, and an eager three year old, I set about painting the potato (which had been whittled down tremendously to fit in the final display).
I used a tan acrylic base, and sponged in darker brown to make the dirt and eyes.
Step 4: Assembly
Here's where I started to feel like things were really coming together - assembly!
Step 5: Can 'Er.
A few final adjustments, and done. Not perfect, but hopefully he'll get a kick out of her.
We have a be nice policy.
Please be positive and constructive.
