Those aren't too bad - it's the bundled wiring driving me crazy. I can probably do something with it if it is just a matter of cutting them shorter and reattaching the USB dongle or whatever is on the end with some solder and wrapping it in electrical tape. I'll know more tonight when I try to fit everything inside permanently. |

Do you have a list of what is being powered in your cab, and what power those devices need? You really don't need all of that bulk in there. If you can work around it that is fine, but we can come up with a better plan if you need more space. |

Things that need power: - Raspberry Pi: Micro-USB powered (5.1V @ 2.5A) - Amazon Basics PC Speakers: USB powered (5V) - USB LED Strip Light: USB powered (5V) - Monitor: Brick powered (DC12V @ 1.0A) - Servo motor (for ServoStik): Micro-USB powered (5V) - ipac: USB powered (5V? not sure) I think that's it. The pi needs to be powered enough to run the ipac as a "controller", the servo motor and the LED strip light (so that when the pi comes on the marquee lights up). The pi, monitor and speakers are currently plugged into the power strip with everything else running off of the pi. The speakers can just stay on all the time (or if I'm not being lazy, I can use the knob on the back of the cabinet to turn them off) and the monitor is "hot" but only comes on when it is receiving a signal. It all seems to work (other than the servo which I haven't figured out yet) but cramming everything in is going to be tight. I already ordered a 18" HDMI cable and a 12" USB cable to try and save space. |

Then you take the above and step down to 5V, 9V, 12V whatever you need. I used them in my control panel. It would save you a ton of space. |

Or just a small 5V power supply for almost all of your stuff, and a small 12v supply for the monitor. https://www.alliedelec.com/product/mean-well-usa/rs-15-5/70069559/?gclid=Cj0KCQjwjMfoBRDDARIsAMUjNZqMoGHjJyekWjjebk8Lh6wBOENHSKa1R3iwWAGMX5stkccmU-CoY9EaArB-EALw_wcB&gclsrc=aw.ds There are supplies that provide more current if it is needed. There are also dual output power supplies 12V and 5V, but I am not sure how small they are. |
