Before getting started:
Here are the extra materials you’ll need:
- A pair of scissors
Here’s what your kit comes with:
- LilyPad battery pack – to power your circuit
- CR2032 3V lithium coin cell battery – to power your circuit
- 2mm 3V DC vibration motor
- Fillable plastic bauble (to hold everything together)
- Tiny bells (to make noise)
- Tissue paper (for decorating)
- Pipe cleaner (for decorating)
- Googly eyes (for decorating)
Here’s what you’ll need to do before starting the kit:
- Test the battery and battery pack.
Make sure the LilyPad battery pack is switched off.
Insert the 3V coin cell battery into the LilyPad (positive (+) side up).
Connect the LED (tiny light) to the LilyPad like so:
– connect the red wire of the vibration motor to the positive (+) terminal on the battery pack
– connect the blue or black wire of the vibration motor to the negative (-) terminal on the battery pack
Turn the LilyPad switch on. If it’s working correctly, the vibration motor will turn on and start to shake!
If nothing happens, check the connections between the LilyPad and the motor, or try changing the battery.
When you’re done testing, remember to switch off the LilyPad and take out the battery, to preserve the battery life.
You’re good to go!
What is electricity?
A type of energy or power fueled by the transfer of electrons from positive and negative points within a conductor.
Electricity is measured in power units called Watts (W).
Current is the rate at which an electric charge flows. Imagine the charged electrons as a river – current is how quickly the river is flowing.
Current is measured in Amperes/Amps (A).
Voltage is what makes electric charges move – it is the ‘push’ or pressure from the circuit’s power source that moves charged electrons (current) through a conductor. As a river, voltage would be its force or power.
Voltage is measured in Volts (V).
Resistance is a measurement of how much the component will reduce the current flow. Resistance is like a pipe that current flows through – a bigger resistance means a smaller pipe, so the current flow is less.
Resistance is measured in ohms (Ω).
What is a circuit?
An electrical circuit is a path in which electrons from a voltage or current source flow.
An electrical circuit includes a device that gives energy to the current, such as a battery; devices that use current, such as lights or motors; and the connecting wires between devices.
Direct current (DC) is one-directional. The positive charge flows away from the positive terminal of the power supply (e.g. the battery) towards the negative terminal, moving through the circuit to get there.
This is why some components need to be connected in a certain way, for example batteries, which have positive and negative markings to show you.
Some components, like LEDs (Light Emitting Diodes) have one long ‘leg’ or (the positive pin, or anode) and one short pin (negative, cathode), so that you know which way they are “facing” in the circuit and what direction the current should flow through them. Other components may also have an anode/cathode but will be marked a different way.
Some components, again like LEDs, require extra resistance to be added to circuits too (in the form of resistors) to limit the current through the LED and prevent it burning out.
In your Tinderbox Makerbox kit, you have all the components to make a simple circuit and they are marked by the manufacturer to show you how to connect them.
Always be careful when working with electronics and practicing circuits.
1.Pop the battery into the LilyPad (positive/+ side up), but don’t switch the LilyPad on just yet. It’s easier to do this step now rather than later as it’s less fiddly!
2. Reconnect the motor like you did when testing the battery (see above).
3. Use the velcro underneath the LilyPad battery pack to attach it to the velcro on the bottom of the bauble. This will keep the battery pack nice and still!
4. Hang the bells over the motor using the wire.
5. Use the bluetack to fix the motor to the top of the bauble, covering the wires of the motor so that the motor hangs down (and doesn’t shake the bauble
6. Turn the LilyPad switch on. The motor will power on and start to shake the bells, making noise!
7. Turn off the LilyPad switch for now. Decorate the outside of your bauble! You can use tissue paper, pipe cleaners and glue, or googly eyes, to give your bauble character. What design can you make?
Tip: Remember to decorate the two halves of your bauble separately, so you can still open and close it to turn the LilyPad switch on.
8. Wind some ribbon through the bauble loop to make a hanger.
Switch on the LilyPad, close your bauble, and hang it somewhere for all to enjoy!
Tip: Remember to switch off your LilyPad when you are done admiring your decoration, to preserve the life of your bauble.
