here is a way to do a (very) simple paper lantern;
I used it in a garden party last summer; a dozen were made, so at the end of the evening each child got his own glowing lantern to bring at home (and decorate with felt-tip pens, for example...)
Only One solder point is necessary; good for a non-pro like me :-)
Step 1: Materials and Tools;
- A paper bag; in my case was white, light 'silk' paper;
- a white led;
- 2 AAA batteries;
- a battery holder with the 2 terminals on which you can solder the led on (I don't know the exact name, please see the photo...);
- a small rubber band;
- Copper wire, thin enough to be cut with common scissors (easy to bend without any tool, also); mine was salvaged from an old transformer.
Soldering Iron; scissors;
Step 2: Soldering the Led
The led is soldered directly to the battery holder;
Please take care of the polarity: usually the longer pin of the led goes to the + of the battery; to be sure, you can test it before to do the soldering.
2 AAA batteries give 3Volts, enough to light the led but with reduced power: this was good for the kind of light I was looking for, and with the reduced power I didn't need for a real led driver circuitry.
Please notice that I soldered only one of the two pins of the led: in this way the 'free' pin can be used as a simple switch, the elasticity of the pin's metal can keep in the right position with an acceptable electrical contact.
Step 3: The Suspension System
For the suspension of the lantern, I used copper wire to do a simple hook: in this way no need for any knot.
Of course, you can use any wire, cord, string, of your choice.
Step 4: Composing the Lantern
1 - Put the batteries in the holder (in the correct direction... :-) .
2 - turn on the led by putting the 'free' pin in contact with the holder terminal (see step 2).
3 - put the holder with the led in the bag: the holder have to be near the 'entrance', and the copper wire have to stay outside;
4 - close the bag with the rubber band, trying to embrace with it both the paper and the battery holder (see picture);
5 - hang it where you wish.
That's it, it's done; thank you for your attention.
