Brainstorm. Self scoring Cornhole aka Bags game.

Maybe some kind of reed switch or magnetic detection. the magnet could be in the bag. and have some kind of sensor like a hall effect sensor - http://en.wikipedia.org/wiki/Hall_effect_sensor

If you could put an rfid tag in the bags that could be one approach. Makes it easier to automatically identify bag colour.

That was what I was thinking, however, I don't know how it would be able to tell if it missed the board. I could put another platform under the hole to tell if it made it. But, yeah, still have the problem of completely missing. I know when I play, I do that a lot. But yeah, we are kind of on the same page on how to go about doing it though. Thanks.

I know nothing about Hall Effect sensors, reading everything I can about them now. Thank you! If my quick glance over the wiki page is right, this might be a viable solution.

I was thinking of the method using magnets because it does not require

batteries on the bags. from what I understand about RFID is the bags

would have to have a battery. you could possibly have some kind of timer

that if nothing is detected it would time out. but not sure about that.

Hope i can help more at sometime.

After doing some reading, I don't think it would work. 2 flaws I have seen so far. 1. Would not be able to differentiate from players. 2. Seems the hall effects sensors need to be facing a certain direction to be detected correctly. Though this has kind of sent me down a road that may lead to something? We shall see. Thank you. It's a strange problem that I know can be solved, I'm sure very easily. I'm just not seeing it.

well the simple method would be to have a lever that the bags hit to detect a score. but you will not know what team and you will not be able to detect a miss. So let me think about it and sleep on it. if i have any ideas I will be sure to pass them to you.

You could set a fixed time to launch for each player.... and the total fail could be on timeout ... I mean you can calculate the time the ball spend from "hand to basket" plus the time to recover the ball, etcetera.

I think you can come back with the hall effect with this workaround...

Please excuse me for my bad English

Passive tags do not require batteries.

That is for sure a way to do it. However the game itself is usually played on a nice sunny day with friends while barbequing and drinking some beers.  Adding a timer doesn't seem the best way to do it. Unless I added a button to press at the beginning of each players round. That certainly is an option though. Thank you.
