Title: low-voltage solution
Post by: Huskerfan on February 14, 2020, 03:21:49 pm

Hi,

Years ago I was using a powermite to power coin door bulbs, track ball lights, and speakers.

I'm basically re-doing my whole setup.

What are people using these days?  Sorry, I tried to search "low voltage" and it was difficult to find anything.

Thanks

I use something like this:

with LEDS, resistors, and old phone chargers from thrift stores.

Whoah!  That seems over my pay grade!

Anything store bought?  Plug and Play?

But thanks!  That's pretty cool!

12v leds lights?
resistor is built in so you just provide 12v from a wall wort or PSU.

I'd just go ahead and knock it down to 5v if you are going to refit everything.... then you can power the whole thing with a powered usb hub/charger.

I found a youtube video where you can McGyver a pc power source.  Just hook up the green and black wire for constant power and yellow is 12 volt.  Pretty cool actually

any game you have in your cabinet needs power.... just steal power from that power supply. 5 volts, 12 volts... whatever.

i normally use one of those cheapy arcade power supplies https://www.amazon.ca/16A-Arcade-Switching-Power-Supply/dp/B00F1YQDBA

i tag off a ground (usually coin switch) and then run the positive wire into the cabinet and crimp a spade connector onto it... then i can put it on whatever voltage i need.... if i run out of 12v wedge bulbs and all I have are 6v 555's (which I have stupid amounts of)... i can just move it onto the 5V connector.
