Team Work

As a team we all work well together. We came up with our concept and developed our ideas; feeding off one another and came up with strong concepts and a final that worked and presented our idea well. For this assignment there wasn't anything we could work on separately so all work was done and developed together through meeting up outside of class.

A2 Presentation


Week upto presentation


We added an Arduino to show the feedback of a flashing LED light that would happen once reaching a sustainable amount of water used. We used the Arduino code to delay and turn on the light once getting through 1.5L of water that we used for our presentation. We worked out how many turns it did in a certain time and for the 1.5L. 



We made our water wheel inside a pipe to show how it would really work and what it could look like. 



Kept the connections to the calculator and reed switch. Covering it so we were able to present our concept actually using water. 


calculations to figure out sustainable volume of water and how long it would be. Also helping us set up the Arduino code.

Final Presentation

Interim feedback

- Fit into waste pipe
- How does it communicate the message?
- Add Arduino
- Serial monitor counts turns of wheel
- Focus on volume of water being used
- Put into a pipe to show it better
- What would it look like and where would it go?

What we need:
LED light
More wire
1K resistor

iSAVE:   Made for the shower head and tap faucet. Attaches to your sink or shower head and provides a digital reading of the amount of water you're using. It is powered by energy that is made by the water passing through using a small turbine embedded in the device. Made to show people the amount of water they are using/wasting.

Domestic water meter: Cane be attached to standard tap and shower fittings in homes. Measures water coming out of single outlets, showing the user how much water consumption is happening. Measured by and internal turbine and sensor and the water usage is displayed in liters on a LCD screen. The unit has an internal generator that recharges batteries so there is no need for replacing them.

-An arduino connected to a LED screen catching the amount of turns the skateboard wheel does swell as showing how fast it is going.

- Turns, revolution and rotation counter. Hacking a calculator and connecting wires to a reed switch, when it is closed by a magnet it adds up on the calculator.

Prototype


 We hacked a calculator and attached it to a reed switch so everytime the magnet passed the switch the calculator would count this as one revolution of the wheel. We put in the function 1+1 =


 The magnet attached to the wheel


We attached the wires to the equals button

Connecting wires to the back of the calculator, connecting to a reed switch that reacts to a magnet we have place on our turning wheel. This wheel turns by water flowing through it. The reaction is counting how many times the wheel is turned, ultimately given us a clue as to how much water is being used.

Ideas for building Haptic Interface

A drawing of how our haptic interface could work:


- Build something that spins a number of times to set off an alarm
- LED's that change as you use more water
- Arduino to count up up how long it's going for
- Coil, magnet, moving magnet past coil to introduce a current, hook up to LED
- Code it to make it trigger something physical.
- Reed Switch
- DIY revolution counter

Wireframe for Haptic Interface


Our idea for a Haptic Interface

Group Haptic Interface

What does it do?
Allows home owners to measure how much water gets used and give you feedback.

- 227L of fresh water flows down our drains in a day per person.
- This is over 100 times the amount of the amount of fresh water we need to stay alive.
- Showering uses 38L per every 5 minutes, 76L per every 10.

- Our Haptic interface will signal you when you use more than recommended.
- It will start again for the next person to take a shower.
- It will measure the amount everyone uses through out the whole day.
- Give feedback by beeping when you reach the recommend amount of water used.

We are aiming to make something that will help people be sustainable.

Haptic Interface: user scenarios

Waving a light on and off
- No need for touching
- Sensors (heat or closeness)

Standing in a certain spot in the room for any amount of time to active either…
- Music
- Light
- electronics to turn on

Shower turning on as soon as you enter it
- Teach it what temperature and pressure you like it

Projector on wall with sensors 
- Universal remote for your home
- Touch wall  and sensors to get what you like

NEST- https://nest.com
When thinking about how we would portray our system and how it would look we got inspiration for the aesthetics from nest. We wanted it to be clear and understandable and look good too.
