It depends on how beginner friendly you want to make it, but here are some more ideas for you to play around with. Also you now owe me a beer.
>Assembling a basic solder kit for beginners. Think solder types, soldering station vs soldering iron with temperature control vs cheap "one temperature fits all", helping hand and all that stuff.
>An introduction to power supplies and calculating battery life. Think traditional batteries in series, (USB) powerbanks, power tool batteries and such. Covering boost converters (ie 5V to 12V) would be nice too, and of course there's the "hours of battery = capacity in mAh / consumption in mA * 0.7" formula for battery life.
>Hooking up a breadboarded prototype, show people how to use a breadboard and explain how there are rows inside so people actually understand how those magical holes work.
>How to use Multicolour LEDs (basic): Show people how to set the colours of basic LED's using nothing but good old fashioned switches or potentiometers if you want more control over the colour mix.
>Light effects (advanced): using a 555 timer, some elco's etc to get a pulsating or blinking light.
>Multicolour LED's (programming): Now that people understand good old analogue technology, it's time to go digital. Changing LED colours with an Arduino 101, go!
>Light effects (programming): Using an Arduino/RPi to get basic effects like pulses, blinking, disco rave mode, and changing them with the flick of a button.
>The Sounds of Science (programming): Let's add sound so we can give off both a cool light effect as well as a "pew pew" when we pull a trigger.
>Common mistakes: Don't forget to add connector shells and "krimpkous" before soldering wires, follow the colour standards for negative, positive and switch wires, and always keep a printed version of your circuit somewhere safe like inside the actual project enclosure.
