    Hello All

    Can someone help please.

    I would like a circuit that only allows a user to use a 'button' to activate something only once per inserted coin. Other button presses are ignored until another coin is inserted. In the Philippines you can buy timer circuits that allow 10mins power per coin - maybe I can hack one of these?

    Thanks

    You can probably do that by using a set/reset latch http://lmgtfy.com/?q=rs+latch
    that is set each time a coin is accepted to set the latch -the output of the latch enables the buttons. The outputs of the buttons not only trigger whatever it is that the user intends to trigger, but they are all ORED together http://en.wikipedia.org/wiki/Diode_logic and the output of the OR function resets the latch, which disables the buttons until another coin is accepted.

    Are you looking for a timer device to purchase, or is this a construction project?

    Also, does the timer need a 10 minute countdown display, any display, or nothing?

    You can buy timers here that shut off power to the monitor and or switch off usb but if running an emulator powering off a usb joypad then powering it back on does not make the emulator "see" the joypad again. You have to exit the emulator and go back in. So if I use a keyboard hack to make the game exit and return to a games list menu (ie maximus arcade) then user must first insert a coin before they can select another game.
