The Grave

This project is basically is a halloween project which can be used to scare the kids.It is basically when you open the grave there is a scary face popping out of it which is meant to scare the kids away.

For circuit

Cardboard box(from Amazon)

Wires

Aluminium foil

Batteries(3V~9V)

Motor

LED(red)

Decoration

Tape / Glue

Paint(grey)

Cotton

Plastic mask

Do use help while cutting the box as the project is large in size

do not do any electrical work with wet hands

Do not use a high voltage battery or current directly from the circuit

use hot glue gun carefully as there are chances of getting burnt

do not touch positive and negative wires when connected to power source

First for making the tombstone with RIP written on it is one of the most important things of the grave... so for making that

- take a empt box (this box should be smaller compared to the box you are going to use for the grave)

- Cut the box in a tombstone shape using a box cutter. A "D" like structure. (TIP: draw it first with a pencil and then use the box cutter to cut it)

- Check if your tombstone looks like the one in picture at this stage.

Now we will be using the tombstone structure and making it look more like it by decorating it a bit.

- Take grey pain and some paint brushes. Paint the front part of the tombstone.

- Let it dry

*For Perfectionists- Put a second layer of paint and let it dry*

- After it has dried...use a pencil and write RIP

- Using a screwdriver or box cutter rip the RIP on the tombstone

Check up: It should look something like in the picture above.

Take a big box...probably a cardboard packaging of a television.

*Size tip: a 10 year old kid should be able to fir inside the box.

Cut it from the centre so it looks like a two way door which opens on the outside. inside this the dead body for made from mask will be put.

Take the Tombstone which you painted and using glue and duct tape stick on one side of the box. Use some glue also for making it more stable.

it should look something like the picture above

Now as they both are stuck together take a 9v battery and attach the wires to positive side and negative side. make sure they are long enough.

positive - red

negative - black

Stick the battery behind the tombstone so its not seen.

Take a 30 cm strip of wood or a wooden scale and stick the mask on one side of the wooden strip or scale. the other side has to be attached to the motor in the box. For that use hot glue gun or using a thick copper wire tie it to the motor so when motor is on the wooden strip rotates and comes upwards.

This is basically when the box is opened the circuit is complete the motor rotates and because the wooden stick rotates with the mask it will look like the face is popping out. As this will happen in a fraction of seconds it should probably scare the kids.

Use conductive tape and stick it on the corner of the box where the box opening is touching the cluster of wires. So the circuit can be completed. After sticking the tape and adjusting it as per the negativity connected cluster of wires, take another black wire and connect it from the conductive to the motor.

The over all cycle.
Positive side already connected
Open the box > the conductive tape touches the cluster of wire > circuit completes > the motor rotates in clockwise direction > so it pops towards the face of the person who is opening the box
