• Have fun creating three flashing LED greetings cards with funky animal designs
• Use conductive paint to build a working circuit without any wires
• Learn about electronics and conductivity
• Components for three cards with battery, card and LED for each
• Fun for ages 12+
• Each card uses one 3V coin cell battery (provided)What can I make with this kit?
Create an epic greetings card with this power animal card set. From the three funky animal designs to the amazement of a circuit that works without wires, this card set is bound to impress. With 10ml of paint you can draw your path for your flashing LED circuit. This kit comes with three 3V batteries and LEDs - one for each card. It requires no soldering.
How do the cards work?
These cards use Bare Conductive electrical paint to complete the circuits on the cards as well adding to the designs. Conductive, easy to use, water based and non-toxic, this paint is a great way to introduce and play with the ideas of electric conductivity. Conductive paint can be applied to a variety of surfaces other than card such as wood, textiles and some plastics. The paint dries at room temperature, and if you make a mess it can be removed with soap and water.
How can conductive paint complete a circuit?
Insulators like wood, card or fabric have very low electrical conductivity, so you cannot use them to carry electricity. However, metals, plasma and water carry electricity well which is why they are used in electronic circuits. Conductive paint becomes more conductive when it dries. When dry, the paint has enough electric conductivity to complete a circuit, letting you power the LED. Conductive paint is a great alternative to acid etching, as it can be used without gloves and masks. Bare conductive electrical paint is not suitable for application onto bare skin.
