Hot Glue Casting: Instructables Robot {L.E.D. Backlit}

This Instructables is not only about The Instructables Logo - The Robot, But it also about HOT GLUE CASTING!!!...It shows you how you can make your very own Instructables Robot model!!!.. Which could also double up as a cool night light!..

After seeing one too many instructables on How to make the instructables robot, I have been wanting to make one of my own, in my very own way!!!

Now, hot glue is used as an adhesive by most people, but I decided to use it as a casting material... and It turned out really great!!!...

For some amazing pics of it, roll over to the last step!!!... :D

Step 1: Gather The Supplies!!!

• Sugru {Red}. [Buy it , or win some by posting some awesome instructsbles!!!...  ;) ].
• M-seal {epoxy} (optional -- may use sugru or any other epoxy in it's place). {Any epoxy from your local hardware shop would do the job!}.
• Elmer's glue (or fevicol or any other similar glue from your local crafts store!).
• UHU super glue (optional). {Buy it here}.
• Clear Tape / Electrical tape (optional). {From your local crafts store!}.

TOOLS REQUIRED:

1. A Hot Glue Gun. {Buy it here}
2. Cutter Knife.
3. A pair of Scissors.
4. Soldering Iron with Solder (optional). {Buy it here}

• Black Chart Paper.
• A female USB port.
• A male to male USB cable.

• A Power Switch (3A, 250V -- ratings actually depend upon the supply voltage in your country).
• Connecting Wires.
• Pet Bottles {or any other sturdy plastic would do the job!).
• L.E.D.s {The more, The Better!!!... I used 40 L.E.D.s -- 3.6V, 18mA}.

[Bobblehead Einstein]

[Siddharth Jain]

It's a mess for sure!...

[Bobblehead Einstein]

[Siddharth Jain]

Very cool idea. Since I didn't see it in the materials list: what kind of oil did you use? I'm planning on doing this for a project of my own. Though I'm using plywood as the thing I'm casting in and so I don't know that oil is even what I'd want to use on that, but I'm still curious.

[Siddharth Jain]

Well I just used the mustard oil...but I think any other vegetable or machine oil shall do the job equally well!..(I'd prefer machine oil though with plywood...).... :D

Can't wait to see your results!!!!!..... :D

cheers!.... :D

This gives me sooo many ideas... Just a quick question. How many hot glue sticks did you use? And the glue won't stick to the tape?

Great job!
Adam

[Siddharth Jain]

I just used around 8 glue sticks of 11 inches each....
2 for the head, 2 for hands and legs and the remaining for the body.....

well, it might tend to stick to tape if no proper oiling/lubrication is done....

:D Thanks!!!... :D

[skj99]

this sure is a winner!

[Siddharth Jain]

:D Thanks!!!... :D

[chaitanyak]

I think it's time that I should ask for help on the help forum....

Thanks a lot by the way!!.... :D
