Below are all of our design specs and how we intend to test them.

Generate electricity: The Voltage Test

Durability: The Force Test; The Safety and Durability Test

Usability: The Force Test

Scalable: NA

Cost: NA

Reliability/consistency: The Safety and Durability Test

Scalability and cost were not tested as their experimental potential was severely limited.

We have done testing on the following:

• voltage required to run the circuit

• voltage produced by the generator (10-20mV average)

• voltage produced from the flashlight (20-22 average)

Date: 4-19-2021; Retest 4-26-2021

Location: The EDD Room

This is a proof of concept test. The purpose is to determine if the prototype is able to successfully transform energy from kinetic to electrical energy.

[Due to our prospective design changes, this test may double as a test to determine whether or not the prototype can transform the motion from the door into a stationary circular motion.]

The test is passed if the flashlight lights up as a result of the opening of the door with a reasonable amount of force.

• Flashlight with open side

• Door/Door model

• Prototype

• Door/door model is closed

• Prototype is mounted correctly on the door/door model

• Someone is in a position in which they can see whether or not the flashlight turns on

Electric shock

The flashlight does not have any exposed wire

If there are any obvious signs of danger (ex- sparks, smoke, ect), the test will be terminated.

1. Set up to initial conditions

2. Open the door and see if the flashlight lights up

Additional Comments: The force and speed used to open the door should be varied within reasonable limits

We have done testing on the following:

• voltage required to run the circuit

• voltage produced by the generator when handspun (.8-1V average)

• voltage produced from the flashlight (20-22mV average)

Date: TBD

Location: The EDD Room

The purpose is to determine the amount of force required to open the door/door model in a given amount of time. Each time requirement is meant to mimic the different ways of opening and closing a door such as sneaking in, normal opening, and slamming the door. The forces found during this test will be used to determine the extent to which the prototype hinders normal door opening/closing ability.

The prototype passes if the prototype requires no more than 115% of force required by just the door. On a full-scale door, the prototype and door should take no more than 5 lbs (22N) of force to open when opening at a normal pace.

• spring scale (available from ellingson)

• prototype

• door or door model

• timer or metronome

• door/door model is closed

• prototype is mounted correctly on the door/door model (after control tests)

• someone is in a position in which they can see the amount of force registered on the spring scale

Electricity Concerns

The prototype will be grounded. Experimenters will not be within 10cm of any open wiring.

The test will be terminated immediately if any of the following occurs:

• electric shock or sparks

• there are signs of overheating wire (smoke, melting insulation, etc)

• any injury occurs

1. Attach the spring scale to the door/door model

2. Do not attach the prototype yet

3. Pull the door open in a given amount of time and read the force on the spring scale

4. Pull the door closed in a given amount of time and read the force on the spring scale

5. Repeat steps 3 and 4 for all times listed above (4 trials each)

6. Attach the prototype and repeat steps 3-5

Additional Comments:

• mark the highest amount of force seen

• try to have it accelerate all the way through - constant force

We have done testing on the following:

• voltage required to run the circuit

• voltage produced by the generator when handspun (.8-1V average)

• voltage produced from the flashlight (20-22mV average)

Date: TBD

Location: The EDD Room

To determine the amount of voltage produced by different forces and times.

The test is passed if the prototype produces a minimum of .8V

• multimeter

• door/door model

• prototype

• timer or metronome

• door/door model is closed

• prototype is mounted correctly on the door/door model

• someone is in a position in which they can see the amount of force registered on the spring scale

• not attached to circuit

Electricity Produced

The prototype will be attached to a multimeter using alligator clips. Experimenters will not be within 10cm of any open wiring.

The test will be terminated immediately if any of the following occurs:

• electric shock or sparks

• there are signs of overheating wire (smoke, melting insulation, etc)

• any injury occurs

1. Ensure the model fits the initial conditions

2. Pull the door open in the given amount of time and read the voltage on the multimeter

3. Close the door in a given amount of time and read the voltage on the multimeter

4. Repeat steps 2 and 3 until all times have been accounted for 4 times

Additional comments:

• record the average high voltage for each trial

• make note of whether or not the voltage is relatively constant throughout the trials or if there is significant fluctuation

• make note of which trials will produce the wanted amount of voltage

• this test could be done at the same time as the force test if there are enough people to take measurements

We have done testing on the following:

• voltage required to run the circuit

• voltage produced by the generator (10-20mV average)

• voltage produced from the flashlight (20-22 average)

Date: TBD

Location: The EDD Room

Determine how well our prototype withstands different conditions and repeated use.

The prototype passes if after several different types of closings, repeatedly, the prototype is still hitting baseline voltage (as determined by the voltage ratings found in the previous tests) then the prototype passes.

• door/door model is closed

• prototype is mounted correctly on the door/door model

• someone is in a position in which they can see the amount of force registered on the spring scale

Estimated number of times opened and closed before the voltage test:

1. Ensure the initial conditions are met

2. Open and close the door at least 800 times with varying speeds

3. Make note of any wear and tear that occurs during the test

4. Make note of any limitations to the opening/closing process

5. Repeat the voltage test… directions pasted below

Voltage Test:

1. Ensure the model fits the initial conditions

3. Close the door in a given amount of time and read the voltage on the multimeter

4. Repeat steps 2 and 3 until all times have been accounted for 2 times

Additional Comments:

• record the average high voltage for each trial

• make note of whether or not the voltage is relatively constant throughout the trials or if there is significant fluctuation

• make note of which trials will produce the wanted amount of voltage
