It is a glasses lamp. When the sensor touches the wearer’s face the LED turns on.
Materials: 1megaohm resistor, ATtiny, Battery, LED, Conductive tape
I applied the basic capacitive sensor circuit on a sunglasses by connecting the sensor pin to the top of the glasses where touches the wearer’s eye bone.
ATtiny – Human Circuit
Whenever people grab the cup cover, the LED light turns on.
Materials: ATtiny, 3v Battery, LED, Conductive tape
It’s a pillow lamp.
In my original idea, this lamp could light up automatically when environment getting dark. When users laying heads on it, the light turns off.
But there is some problem with ATTiny. Finally the lamp can be turned off when laying heads on it. But it can’t light up automatically when environment getting dark.

Soothing/Comforting/Purring Pet (Or rather: The Angry Firefly)
Don’t wake up the angry firefly…
The plan for my Behavior Story took a detour when I underestimated how loud/strong the vibration from the mini vibe motor could be. I had initially planned on making a nice, soothing toy/object that created a gentle vibration and pulsing light when you put your hand on it. Instead what I got was an angry cricket/firefly that was irritated when you bothered it.
A photoresistor at the top of the jar detects when the user places his or her hand above it, causing the angry firefly inside to wake up (lighting an LED and powering a mini vibe motor in short pulses) until the user’s hand is removed.
Materials:
for the vibe motor circuit:
The project is my first attempt at using a Trinket microcontroller with soldered connections – something I tried in order to keep the components as compact as possible. However, the project still required a 9v battery to work effectively (the vibe motor requires a decent amount of power), making it bulkier than intended.

Maybe ancient civilizations are more advanced than we think they are…
If you ever enter one of these caves.
Just hold the painting’s hands,
Unexpected things may happen…
“Kick!”
I chose to embody the word “kick” and felted a little adidas soccer shoe. I then attached it to a servo and coded the servo to rapidly move forward about 45 degrees, like a kick, and then slowly move back to its initial position. I then attached a button that I made out of felt to the circuit and coded it to “kick” the foot when pressed.
Check out the video below!

Behavior Story_Wave
On his first day of fifth grade, Bob, decided that he was finally going to say hello to his kindergarten crush, Beca. The only problem was that Bob was so shy he could never muster the courage to actually speak to Beca. So, Bob did what Bob does best, and built a waving robot to do the talking for him.
Unfortunately, when he used it at school Tess, the girl sitting in front of Beca, thought the wave was meant for her. Tess walked over and started talking to Bob….and never stopped. The two lived awkwardly ever after.
The heart beats fast when the flower bunch gets close to it.
