Light Up Roto Copter
WHAT WILL YOU MAKE?
WHAT WILL YOU NEED?
- 1 Sheet of card stock
- 1 Binder clip
- Circuit Stickers
- Copper tape
- CR2032 battery
Halve your sheet
Measure 4 1/4 inches in from the long side of your card stock at the top and bottom. Connect the dots with a line and then cut along that line to divide your sheet in half.
Measure 5 1/2 inches from the short edge of your sheet and draw a dashed line. Do not cut this line, dashed lines will be used for fold lines later.
Measure 2 1/8 inches from the long edge and draw a line from our last line to the top edge of the sheet.
Measure 2 inches down from the center line and draw a line across the short section again.
Measure in 1 1/2 inches on this new lower line and mark each spot. Erase the line between the two marks. Now draw a dashed line down to the bottom from each mark.
Fold it up
Fold the two lower flaps back along the dashed lines you drew. You should now have one thick center section on the bottom.
Trace the battery
Place the battery on the lower center section near the bottom and trace a circle around it. Move it up about a half inch and trace it again.
Mark and fold
Mark the bottom circle with a + and the top with a – to indicate how to place the battery later. Fold the paper up between the two circles, lining them up with each other, and press tightly to create a crisp fold.
Start adding tape
Measure 9 inches of copper tape and then run it from the center of your – battery circle up the right hand top strip.
Measure 7 inches of copper tape and lay it down about 1/8 inch to the right of the first strip so it comes down to just below the cuts for the bottom flaps.
Tape to the side
Measure an inch of tape and tape it down so it connects to the right hand strip of tape and then comes further right onto the right hand lower flap.
Measure 2 inches of tape to come down straight from the previous line. Now measure enough tape to connect that line to the center of the + circle at an angle.
Take out your circuit stickers and find the + and – markings. Stick them so those markings line up with the strip of copper tape that connects to the same marked circle: + to +, – to -.
Fold and clamp
Fold the bottom two flaps back again to protect the strips of tape on the right hand flap. Place the battery on the circle, paying attention to the polarity of the battery, then fold the bottom of the flap back up, completing the circuit and clamping it in place with the binder clip.
Try making the smallest Roto Copter you can. How small can they get before they stop working? Try without the electronics. Take a look at a maple tree seed pod, do you see any similarity?
