Copper Tape LED Christmas Tree:The above render shows how the completed parts slot together to form the finished tree. Although getting the tape cut correctly might prove a little tricky, once the circuit has been made the rest is plain sleighing...
Step 1:Chose your preferred colour of LED. If using RGB LEDs, use the battery to identify which pins you will need to use. Use some clippers to remove the extra pins.
Step 2:Using a pair of scissors, cut the copper tape into strips with the cut-outs as shown.
Step 3:Take the first half of the tree with the cut out for the battery and insert the LEDs in place. Place the tape over the battery hole on the same side as the positive pins of the LEDs. Fold the pins down 90° and cover with the tape and press down firmly around them. Feed the tape through the slot in the tree as shown and stick down on the opposite side. Using a ruler may help pass the tape through the slot.
Step 4:Place the battery face down in the hole and cover both the battery and remaining pins with tape. Make sure there is a small gap between the two pieces of tape.
Step 5:Place two of the LEDs in the other half of the tree as shown and fold the pins 90° upwards. On the same side as the negative pins, press the tape over as shown and fold around the slot in the tree. Before pressing down at the top, place the last LED in place with the negative pin on the same side. Push the pin as far to one side as possible for clearance of the other part of the tree. Press the tape over the pin.
Step 6:Place the last piece of tape over the LEDs on the opposite side and press firmly around the pins.
Step 7:Use scissors or a sharp knife to cut the remaining tape from the edges. Ask an adult for help if required. Finally, slot the tree together and watch the LEDs light up as the circuit is closed. This concludes the forth of our 12 Makes of Christmas, we'll be back tomorrow with another festive making activity. You can check out the other Makes of Christmas, here.
