This kit contains five light-emitting diodes arranged in the pattern of the brightest stars in Cassiopeia. When switched on, the l.e.d.s flash on and off, independently, to make a sparkling display.
Different versions of this kit are available:
the STANDARD kit contains one l.e.d. of each colour (blue, green, pink, red and yellow),
ALTERNATIVE kits contain five l.e.d.s of a single colour (either all blue, all green, all pink, all red or all yellow).
Please state "STANDARD" or the COLOUR you require in the "note to seller" box at the checkout.
Watch the circuit working on the Irby Electronics YouTube channel.
When this circuit was tested, a set of Duracell Plus Power batteries was still producing a good light output after 90 hours of continuous use.
The circuit is made on foam board (approx. 16 cm x 10 cm) and requires 2 x AA batteries (not supplied). The joints in the circuit can be made by simply twisting wires together and then crimping the connection with pliers. Soldering, however, makes a better electrical joint.
These tools are needed to make this kit (not supplied):
small pliers for bending component leads,
small wire cutters for cutting link wire,
slotted screwdriver for securing foam board to wooden base,
small, low power soldering iron, e.g. 15 watt, 18 watt or 25 watt (only if soldering is to be attempted).
Please read the safety warning in the About Irby Electronics section before ordering a kit.
