A while ago, as my first microcontroller project, I made a Pong game on a 5x7 LED display, but then nothing became of it. Recently I was given a hard hat as part of a uniform (for an engineering competition) and told to customize it, and remembered pong.

In this instructable I will show you how to make a scrolling LED display and how to install it in a hard hat. It also plays pong!


Step 1: Materials

Picture of Materials
Parts:
-2 10k potentiometers
- 3 4.7 kOhm resistors
-4 SPST toggle switches
-1 5x7 bicolour LED display
-1 8 pin dipswitch
-1 Hardhat
-1 atmega168 microcontroller (or arduino)
-1 28 Pin 'skinny' socket
-1 breadboard
-1 3.7V lithium polymer battery
-Wire
-Solder
-Hot Glue

Tools:
-Soldering Iron
-Hot Glue Gun
-Wire Stripper
-Hobby Knife
-Plexiglas Cutting Knife
- Microcontroller Programmer (optional)
 
well thats a really nice project
I am Greek and the letters ertw are greek so i wonder if they or u are related to greece someway
i cant though find their meaneing i would love an answer

Does ERTW stand for Electronics, Robotics, Technology, W00T?

Nope, Engineers Rule The World.
love the hard hat and love the choice of song.

Cool But I think someone had just too much time on their hands.

That was simply awesome. Nice project.

Very cool project! And just ever so slightly geeky. :-D

That 5x7 LED display is a great find, by the way - $1.49 for 70 LEDs! That's just over 2 cents per LED - must be some sort of record...

Since you're at an engineering school, I assume ERTW stands for Equal Rights Towards Women. Now, can I get my bonus points? ;-)

Google - is there anything it can't do?
J_Hodgie (author)  Patrik7 years ago
Thanks for the comment. Not quite, but it is in the link.
it's engineers return to work, i think this because you say the hat is for an engineering project.

yes it cant give me pages for my school reports

Great project. Well done. I will be able to learn a lot from studying your code. I'm just not sure about the bi-colour display. Will I need to change much in the code if I just hook it up to a single colour matrix? Thanks for posting the code.
J_Hodgie (author)  sidgug7 years ago
No, I just controlled the bi-colour display in the hat through the dip-switches above it, so the code is already in one colour.
you are a genus but im only 10 and cant do this but i'll probaly try i'd put it on my math book need some thin to do lol

Very very nice work. I was looking for an Arduino project. This looks like just the thing!
DamionLee7 years ago
That's a nice Instructable. Almost has me ready to go into the attic to find my old hard-hat. Think I may have to find some other housing for it instead. Well done.

Awesome! This is similar to this; only your led matrix is in landscape, which makes pong much easier to play! Nice job.

Is there a way to program the display using a Mac?
J_Hodgie (author)  noremakk7 years ago
Yes, there is. There are also some more resources at http://www.arduino.cc/

Nooooo liner?? Canya nay wear it, laddie? (awwwww, you get a + anyway. Nice job.)
J_Hodgie (author)  gmoon7 years ago
There is a liner, it is propping the helmet up in the main photo. I just removed it to take a picture of the finished electronics. And thanks for the comment.

Hey, do you go to UOIT? Also, engineers rule the world
455H013 455H0137 years ago
Replying to myself, it says you do on step 9. I'm a second year mech eng.
J_Hodgie (author)  455H0137 years ago
Yes I do, I am in second year mechatronics.

I agree with Gorillaz, this is cool
Incredible job. Reminds me a lot of Kiteman's UV Ray light Instructable.

Oh, I thought it said, "with bong." My bad.

My lord. This just reminded me of one of the funniest Overheard in New York posts of all time:

And What Part Will the Helmet Play in That?

Nerdy hipster to friends: You want nerdy? You know what I did today? I worked on this robot helmet I'm making on my floor. Yep, a robot helmet complete with LED lights -- for my girlfriend. See? That's love right there.
Girlfriend, explaining: I told him we could have butt sex.
Nerdy hipster, emphatically: But not until I finish the helmet!

Very nice - the long pots make it look quite impish, but aren't they vulnerable to getting knocked off? Maybe shorter knobs would have been better?
J_Hodgie (author)  Kiteman7 years ago
Thanks. The long pots are very sturdy, no risk there, so it is basically what you want (or to get the more authentic pong feeling)
Hey what engineering competition are you talking about? FIRST? an awesome hard hat
J_Hodgie (author)  angelicgundam907 years ago
The competition is the Ontario Engineering Competition. Thanks.
Love it, but where's the video?
J_Hodgie (author)  fungus amungus7 years ago
Thanks, and I' m going to do that tonight.
