In my opinion, no self-respecting nefarious device would be complete without some sound effects. Perhaps when you activate the first switch you hear a motor slowly come up to speed as the light is "breathing". When the second switch is activated, a second motor comes up to speed.
Upon activation of the third switch, use a sound like the "steampunk giant robot" from the Mega Stomp Panic: http://www.thinkgeek.com/product/ef56/
along with activation of a jumbo-sized version of the vibrator motor that is in your cell phone so the suitcase would twitch a bit.
I can't wait to see this come together!
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
