Noob help - How to get all power from Laptop?

Pages: (1/3) > >>

Ritalin:

Hi All,

I'm in the process of building a bartop arcade game which will be running from an old laptop.
I have the laptop running mame and mala smoothly, but I'm now confused about the power.

Since the laptop doesn't have a full sized motherboard and power supply like a standard PC, how do I get 5v power (or ANY power for that matter) from the laptop? (This particular laptop uses a 15V power brick)

One item in particular I want to power is this NovaGemCDR™ Coin Drop Replacement Pushbutton:

Should I buy a separate standard PC power supply for all power needs?
What other power is needed for a control panel hookup with the i-pac2 for example?

I'm a total noob when it comes to wiring and power and power supply issues, so any help is appreciated, thanks.

You can get 5V from the USB port for low powered items.

An IPAC gets its power from the port it is hooked up to. You can hack a USB cable to get 5V and ground for the lit coin button.

What else are you wanting to power? If you are doing some sort of marquee light, then use either direct line power for 120v lights (fluorescent bulb, etc.) or use a wall-wart for 12V lights such as the GGG Novamatrix.

BobA:

GGG makes a usb 5V tap cable if you don't want to build your own.

Excellent info, thanks everyone.

I plan on having a marquee light which I already purchased. It's a standard 120v fluorescent light for under cabinet kitchen lighting.

The only thing I would need to light would be the NovaGemCDR™ Coin Drop Replacement Pushbutton LED.

NOOB QUESTION ALERT: Do the joysticks (mag-stick plus) or any standard buttons require separate power?
