Hockey Table Scoreboard

[murray]

Hello,
I am building a scoreboard for a hockey table. It will have a computer attached to it and will use a 7" lcd tv. What I am wondering is what I can use as a switch to detect the puck as it goes throught the net. I was thinking of using an infrared emitter and detector (like **broken link removed**). I plan on interfacing it into a hacked usb keyboard so that when you score, it hits a key on the keyboard which triggers the software to add a goal.

Will this work?

Thanks

If you have a question of your own, start your own thread.
Dont highjack someone else's thread even though it is a similar topic.

Will this work?

The principle is right. So yes it will work if you do everything you need to.

I once had the idea of making a telephone dialer.
I looked into ways of machanically pressing keys on a telephone, then to using relays to each switch contact....
Then I came to my sences and bypassed all that, because that was all getting a little messy...
I looked into DTMF chips and used a PIC (microcontroller) to control the DTMF chip to generate a Tone, then interfaced it to the phone line and did it that way.
I practically made a telephone minus the handset.

Anyways... the point i wanted to make is with the hacked keybaord, maybe you can look into interfacing stright to the USB port.
I myself have never done this so I cant help you there..
But i know when you press a key on a keyboard, it sends the ASCII character in binary form to the USB.
It would be alot neater and you would learn a lot by doing it that way.

And your idea on using the IR beam is the way to go for counting goals.

Question is... why do you want a computer hooked up to it?

USB protocol can be a pain. Sounds like a project Rube Goldberg would love. Score a goal, a marble falls down a chute, triggers a reed switch than then shocks a monkey in the cage who then starts furiously punching away at a usb keyboard plugged into the computer.

Seriously though, get one of Bill's training boards blueroomelectronics - Smart Kits Build Smart People and skip the keyboard.
