So i have a friend whos openign an internet cafe, and he wants to add in a couple of tv's with a xbox and ps3.

He wants to charge $5 for 30mins playing but he needs someway to control the amount of time they can play for.

Ideally it would be great if someone could pay at the counter and he could either enable the TV for 30mins or give them a code which enables the TV for 30mins.

I have done some googleing but can't find much. I guess either a TV that can run custom software or maybe even a really lite linux distro?

Basically any automated way to switch the tv on/off or control what was displayed on the tv?

Anyone got some ideas?

Cheers

Go to adafruit.com and look at the tutorial for IR commands from an arduino. You should be able to time it to send a IR command to power off after 30 mins or whatever, or attach a coinslot to it to add time etc..

mindkits.co.nz and nicegear.co.nz sell them, both ship out fast, if you talk to @mindkits or @nicegear on twitter and tell them what you want they are both very helpful.

Nice gear is in timaru so perhaps a better option for you for being, whereas mindkits have a much greater selection.

Ok so one thing that came to mind, if their are 2-3 TVs of the same make/model when i send the command to switch off one they will all switch off?

A coin slot to power the TV is the simplest solution (probably not that cheap though)

If the IR LED sending can hit them all, then yes, so multiple LEDs would be what you want to do. There are ones to stick on the front of things, but last time I needed to remote control a TV I just poked one on the end of some cat-5 into a vent on the back and it still managed to hit the sensor in it somewhere.
