  • ...
• Albrecht Schmidt (example): using environmental sensors (e.g. gas, temperature, humidity) and creating smell output
  • connecting coffee cup usage (one side) to coffee smell output (other side)
  • measuring temperature in one place and create a temperature display on the other side
  • ...
• Manuela Eska:
  • Cookie jar connected with a weight sensor (one side), display etc. (other side) that indicates about the filling, so that the next cookies can be prepared when the tin is nearly empty and can be refilled in time
  • Detection of the baby's movements during the night (one side) so that lullabies can be played (other side) so that the baby may not wake up
  • ...
• Sigrid Klinger:
  • Measuring wind direction and force (vane + anemometer) outside at one place and transfer the data to two analog scales at another place
    • Requirements for the Group Project (according to the first email):
      • At least two connected physical objects: Wind and two scales
      • At least 2 or more sensors: A light barrier sensor and magnetic sensors
      • At least 2 or more actuators: A servo for each scale to move the arrow indicating the measurements
      • One sensors has to be “invented”:
        • Force Sensor: Self-build anemometer with e.g. plastic spoons as hemispherical cups connected to a pipe with a pinhole. A light barrier sensor can then measure the rotation speed by counting the rotations every time the pinhole passes through the barrier.
        • Direction sensor: Self-build wind vane: Vane with a magnet. Magnet sensors arranged in a circle can then measure how far away the magnet is. With this the direction can be calculated.

• Leon Dönch:
  • A symmetrical "connect four" (Vier gewinnt) game for two flats, whose squares lights up by pressing. Every time the other player makes a move, a sound is played.
  • Showing if your cat is outside or inside the house by detecting the flap direction of the cat flap. When it is outside, a lasercutted cat moves out of its "house" and starts walking.
  • Same idea as the cat flap, but detecting if a new letter has arrived in your post box and showing this with an LED animation similar to those bar signs
• Wang:
  • greenhouse monitoring & watering system: connecting a mini plastic greenhouse indoor and a real one in the garden or wherever.

In the real greenhouse: soil moisture, and other environmental variables (e.g. temp., humidity) are monitored. When the soil moisture level is below the benchmark, a valve connecting to a water source will open.

In the mock greenhouse: small plastic plants reflect the soil moisture level outside. A display shows all other environmental information.

HW: soil moisture sensor, Tsl2561, Bme280, water shutoff valve, filament, etc.

• Philipp Greiner:
  • plant watering monitor (so a friend knows when to come over to water your plants when you're not at home for some time): Measure moisture of plants (one side), if it's to dry -> activate signal "water plants" (other side), the signal can be anything and does not necessarily have to be a text
  • ...

• Carmen Schanderl:
  • Similar Idea to Manuela Eska "Detection of the baby's movements during the night (one side) so that lullabies can be played (other side) so that the baby may not wake up":
    • Extended Babyphone: Sensors on the door and distance sensors. If the baby is crawling through the door and comes nearer to the stairs, an alarms gets louder on the Babyphone, maybe even with light alarm (red light in the livingroom getting intensive). Sensors for temperature, that you can regulate it.

• Sarah Delgado Rodriguez:
  • Indicator of how "busy" someone is in the office --> firth object on the office door is an indicator (I thought of a clock-like approach, but I am open for other ideas), second object is on the desktop and used to (passively) measure + (actively) change the indicator
