Rudolph The LED Nosed Reindeer:In the above render, you can see how the individual pieces relate to each other. In the steps below you can see how to make the simple circuit and how to put all of the pieces together.
Step 1:Cut the parts using the DXF files on a laser cutter, or print out the templates for use with cardboard. Keep note of the part numbers.
Step 2:After cutting all of the pieces, take the body and fit the LED into the slot in the nose. Gluing this in place may help but is not essential. Make a note of which side is positive/negative (The longer pin is positive). NOTE: These instructions are for the full reindeer – if building the head only, follow the instructions the same, ignoring step 13 and glueing the shield pieces in place last.
Step 3:Using the copper tape, create a solid path on one side of the body leading from the LED to the circle cut-out. This is where the battery will go.
Step 4:Repeat the previous step on the opposite side, but do not cover the cut-out yet. Insert the battery into the hole, with the positive side facing to the same side as the longer pin on the LED.
Step 5:Finish the circuit by placing the tape over the battery. Check the LED is on and has a solid connection. If the LED is not on, check the tape is stuck down fully and check the battery is the right way round.
Step 6:Begin slotting pieces 1-6 onto the body, glueing each one in place. You may need to sand the first 2 parts slightly to fit over the LED pins.
Step 7;After glueing the pieces 1-6 onto the body, you can add a switch to the circuit. If you do not want to add a switch, ignore steps 9-12.
Step 8:Take piece 7 and add some copper tape on one of the inside edges of the slot. For the switch to work best, this piece needs to fit snug – I added a few extra strips of tape for a better fit.
Step 9:Cut a small slit in the copper wire in line with the slot behind the ears. This break in the circuit will be joined with the copper tape on piece 7 when slotted over.
Step 10:Slot piece 7 back in with the copper tape covering the gap in the circuit. Make sure the LED lights up and the piece stays in place - add extra layers of tape if the piece is loose, but do not glue as removing this piece acts as a switch.
Step 11:Continue fitting and gluing pieces until you reach the battery. Do not glue pieces over this as you will be unable to replace the battery.
Step 12;Continue fitting the pieces in place after the battery hole. Leave the pieces missed out on the side for now.
Step 13:Glue the back legs in place as shown.
Step 14:Slot the pieces back over the battery hole and fit the legs into place. You may want to glue one leg to the already fixed pieces however you should leave one side so you can replace batteries if required.
Step 15:Finish by glueing the rest of the antlers on. This concludes the fifth 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.
