Introduction: Amadeus, the Napkins Holder Junkbot

By
About: I'm Mario Caicedo Langer (M.C. for short), a Colombian STEAM educator living in Azerbaijan, BSc in Naval Sciences and former Navy officer. I am a CAD and 3D Printing enthusiast and an artist specialized in jun…

It was an ordinary Thursday on Instructables (sorry, it was Pizza Thursday. We don't have ordinary Thursdays on Instructables. But you get the point). I was in the kitchen, preparing a lemonade, thinking about how to transform a flashlight into a cyborg arm and how not to make more junkbots for the rest of my artistic residence, minding about my own business, when I hear a piercing scream:

AAAAAAAAAAAAAAAAAAAAAAAAAGGGGHHHHHHHHHHHH!!!!!

I quickly turned around, looking for the first aid kit (it could be a medic emergency) or a knife (It could be a rat. A big bad mutant rat with evil red eyes). But the situation was worst than I thought.

They send us the wrong paper towels.

We have displays for scrolls of paper towels, but nothing had prepared us for multifold paper towels. Box-shaped, multifold, horrible, paper towels.

Some people suggested to leave it this way without using the display for scrolls. A beautiful and smart co-worker (I won't say her name because I don't want the NASA take her away from us, due to her extraordinary out-of-the-box thinking) succesfully inserted the multifold paper towels into the cylinder.

But I didn't give up. I had to invent a more complicated way for keeping the paper towels in a display.

Then I remembered I had an extra damaged speaker from the Robot Lamp I made as first project. And it had the correct shape and size. So, how I solved this problem? As the same way I solve most of the problems: Junkbots!!

Ladies and Gentlemen, I give you... AMADEUS, THE NAPKINS HOLDER JUNKBOT!

And if you don't have paper towels or napkins, you can use it for brochures.

(Yes, I know. I promise, the next three projects won't be junkbots. I'm becoming the Derek Zoolander of the DIY world)

Step 1: Stuff

I used the following stuff:
  • 1 small speaker (Logitec), big enough for the napkins/towels/brochures you want to keep.
  • 2 corner brace inside L (1in. x 1/2in.)
  • Plastic junk
  • 1 damaged camera lens
  • 1 damaged webcam
  • 1 laptop power adapter
  • 2 small damaged computer fans
  • Nuts, screws and bolts
  • Iron washers
  • Superglue (cyanoacrylate)


TOOLS

Dremel Rotary Tool
tweezers
screwdivers
scalpel
pliers
Wire cutters
Screwdriver kit
Soldering Iron


And don't forget:

1. If you don't have it, replace it!
2. Use protective equipment (dust mask and goggles)
3. Beware of drilled and soldered hot surfaces
4. Work in a good ventilated area.
5. Always have junk in stock.
6. Wash and desinfect carefully every of junk.
7. Have fun
8. Watch out for the correct shape of your papel towels.

Step 2: The Body

This step is easy to describe: open the speaker and remove everything inside. You will need only the box with the open top. Remove electronics, every extra piece and dried glue.

Step 3: Legs

Take half of the case from the laptop power adaptator. Attach it to the bottom of the box.

Cut the wires of the fans. Attach the fans to the laptop case.

Step 4: Arms

Make the arms using junk. I made a pincer and a blaster. Attach these to each side of the box.

Step 5: The Eye

Remove the lens from the webcam. Fix the camera lens to the center of the front, and glue the webcam lens inside.

Wash your junkbot, let it dry, put some paper towels and enjoy your decorative napkin holder!
