How I add LEDs and circuitry to a TV prop. (with timelapse)

Описание: Since this video is effectively a full job I have used timelapse on sections of it to keep it a bit shorter.
I used a control module I designed a while ago to make adding animated LEDs into props a lot easier. It allows me to use a library of effects I've built up over time to control between 1 and 15 LEDs plus provide power to other non-animated LEDs. It's programmed in PIC assembly code. The controller has all the resistors for the animated LEDs on board, plus large pads to make connection of the interconnecting wires easier in-situ.
I've used a lot of these in various technical props and set decorations on various TV and film productions. They're an ideal way to add a splash of tech to an otherwise inanimate prop.
In the past I've tended to use 4xAA battery packs with either alkaline or NiMh cells depending on the application. Now I've moved towards using USB power banks as they provide a consistent 5V supply, have all the charging circuitry built in and can be swapped quickly and easily. The use of a USB lead also allows a standard phone charger to be used to power the prop.
