I'm stumped. My goal is for when a ping pong ball enters into one of the cups, some type of "proximity switch" would turn on the leds on the side it is on. I guess the ball may be coated with some type of paint to make it magnetic or something and when it enters the magnetic field it would hit some type of switch. The table is pretty cool, I am already putting green UG on it. Hit me up with some ideas to make this thing better!

if it were magnetic like you are talking about, they would go off anytime someone shoots the pong ball

Guys, I have no experience nor knowledge about these types of switches, so give me as much info as you can please. I don't even know if "proximity switch" is the right term lol

It'd be incredibly hard to do. If you did it by weight, it would go off whenever the ball hit a cup. If you did it with magnets, it would go off every time a ball got near it. If you did it using opticals, they'd have to be inside every single cup.

I wouldn't bother.

heres what you do....
pick a guy and tell nobody he is doing it and when a ball goes in a cup he presses a button....
people will go HOW DID YOU DO THAT
You'll spout some technical info about using controlled particle switches and stuff and girls will want to make out with you!!!

Crazy advanced for the use. It would be super cool but hard to create. Liquids and what not making it more difficult.

What about wireless motion detectors within the inner ring of each cup. ? They'd have to be water proof however

then you would need specially modified cups each time.. and they need to be able to move freely when someone moves them or takes it to drink them

I'm thinking of somehow creating a low profile ring that will rest inside of the dixie cup that has a motion sensor that also wirelessly transmits to a switch of some type- o yea and waterproof!

Anyone wanna help me get started on this project?

Put UV LEDs under the cups, and use florescent balls. Then the balls will APPEAR to light up when they go into the cups.

It might pass through red but I highly doubt it will pass through a red solo cup

I guess it depends on if you are trying to just have a lit up beer pong or if you're using it to keep score. If its just to make it all lit up then I believe I red online a few places about LED lit Ping Pong balls, you could look into that. I believe it was on http://www.instructables.com If its for scoring, then I'm not too sure about how to get a cheap, easy, and reusable solution for it.

The lit up ping pong balls is a great idea, but whats going on in my project is that the entire table top of the beer pong table is frosted glass with green leds under it on one half and white leds under the other half. the cups go on the respective sides, and what im trying to do is when the ping pong ball enters a cup the lights on the side of the table it entered would light up. Just clarifying things a bit

any additional weight to a pong ball throws everyone off.
there is really just no easy way to do this accurately

dont mean to sound like an ******* but it is what it is

why doint you see if you can find some kind of laser system that triggers when its passed to throw a switch, thus activating the lights. it cant be that hard..
its the same as the conveyor belt at the grocery store. it keeps going until an item penetrates the laser beam.

.. just an idea icon_cool.gif

look this is exactly what Im talking about:

http://www.electronickits.com/kit/complete/elec/ck1620.htm

it says it can trigger an alarm, but in your case.. it would trigger cathodes/leds, etc..

i think this project is interesting, yet i also believe that this is not very practical being that it is a beer pong table. This is something phil should do?

optical what?

my idea is that an IR beam an inch or two over the top of the cup what would trigger when the beam's broken by the pong ball.

nobody has said that yet : P

It's actually just an optical sensor b/c it's simply an LED in the mouse. It's not a laser. icon_wink.gif

Can you post a picture of your beer pong table ? I'm interested but we don't play beer pong out here so I'm sort of clueless as to what you're talking about . I'm picturing a pool table with recessed cups and I know that's not right .

if you put some kind of optical trigger 2 inches over the cups, it will flash every time someone gets close to getting in.. even if its a miss

No, the point is if it's above the cups, it'll trigger when the ball is anywhere near the top of the cups, including misses.

You'd have to put the visual sensors through the cups, which would require special modding, which is pointless for a game played by drunk people...

New idea, arer there any sensors that can detect the movement of the beer inside the cup when the ball lands in it? How small do the optical sensors get? and how cheap?
