I was struggling with ideas for my next project, then it dawned on me.  I needed a Thinking Hat!

Looking around in my shop, I found I already had all the necessary materials to construct such a time-honored headpiece.  The materials used were:

- an old hard hat
- an old power tube from a previous project (http://www.instructables.com/id/Rescue-a-vintage-TV-cabinet/)
- a toggle switch
- an "AAA" battery holder (and batteries)
- a "mystery" red LED (I call it a "mystery," because it came unmarked in a box of junk parts I bought once upon a time)
- wire
- an empty wire spool
- an old coiled cord
- a little round "thingy" from an lamp
- a couple of feet or so of brass rod
- solder
- heat shrink tubing
- and my old standby....hot glue

The tools used were pretty simple: a drill, drill bits, and soldering gun

Step 1: Preparing the hard hat

The hard hat stood before me like a pure white canvas (photo 1), ready to be magically transformed into a Hat Of Deep Thinking.

My plan was to mount a huge old vacuum tube on the top (sort of like an "idea" light bulb), stuff a red LED up through the base so it would shine through the glass, and wire it all together with batteries and a switch.

Looking around, I realized that the pins of the tube would fit nicely inside of an old plastic wire spool, so I bolted the wire spool to the top of the hat (photo 2).
Cool, and Is the book your reading upside down?
Yes, it is indeed upside down. It's because of the Thinking Cap, you know.....
Yeah, I figured that out.
I really like the hat, but I REALLY like the photo.
You could adapt a TDCS kit to overclock your brain and make it a real thinking hat! ;)
This made me lol and kinda reminded me of portal for some reason. Now you're thinking with hardhats.
The unknown lamp part is called a harp.<br>
Here is a Demotivation from me to you :) <br><br>http://www.demotivation.us/thinking-cap-1250959.html<br><br>I love this instructable, by the way.
Ha! Thanks for the comment, and thanks for the link to the demotivation!!
This is very well thought.<br>As a matter of fact as it was conceived BEFORE you built this cap I think that you don't actually need it and you should give it to someone who's thinking abilities want such a boost : be kind to your neighbor ! &hellip;
Well............... Actually, I didn't think about building it until I taped the vacuum tube to my head and felt its energy filling the great void that exists between my two ears. Then a voice spoke to me saying, &quot;Must get old hard hat, empty wire spool, LED, and lamp part 'thingy' and assemble into a Thinking Hat!&quot; I've often wondered if the voices only speak to me....... Enjoyed your comment!
Aaaah ! That explains&hellip;<br>So make a good use of it. You already did by showing how useful it is.<br>Guess I'll end up making my own ; French style of course, I don't want my fellow countrymen see my think with an accent (but then again !!&hellip;&agrave;.<br>Enjoy your week end as much as I enjoyed your instructable ! &hellip;
coooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo.......... <br>3 years later <br>.....oooooooooooooooooooooooolllll
Silly and wonderful :D
Wonderful, yes, but silly?!?! I mean we're talking about a real, carefully designed and tested Thinking Hat. When it come to thinking, I need all the help I can get! Thanks for your comment!
Brilliant - add a cooling fan and trolls the world over will flock to your door.
The line of trolls at my door is already so long, they're complaining about the long wait time! Thanks for your comment!
Why not make the heater glow? That would have been this much more awesome.
I would have liked to make the actual heater glow, but alas this old tube's heater would not cooperate. Thanks.
Splendid, <a href="http://www.instructables.com/id/Brain-phffArt-Kinetic-Trophy/">great minds think alike</a>.
Thank you! Also, thanks for the &quot;great minds think alike&quot; link -- I enjoyed it.
