that glow when you turn them around.
The only thing you need is some simple electronics!
For this project i used a paper template of a diamond,
you can find them here: http://www.minieco.co.uk/paper-gems-new-templates/
Of course you can also create your own paper model.
The project will cost you about $5,
and won't take more than an hour.
Step 1: All you need
- paper model
download a template here: http://www.minieco.co.uk/paper-gems-new-templates/
or create one yourself
- tilt switch
preferably one without mercury
- LED light
choose a color of your liking, make sure it works with 3V
- battery CR2032 3V
- battery holder for CR2032
- PCB (custom or diy)
I fabricated a custom PCB, send me a message if you want one too!
and possibly a sharp knife to cut out small details
- soldering iron
any kind that works well with the paper you are using
to trim excess material off your finished circuit
- glue gun (optional)
to mount the circuit inside the model
Step 2: Soldering the circuit
plug in your soldering iron and let it heat up while you sort out the parts.
Solder the battery holder, tilt switch and LED in series,
the tilt switch will just break or close the circuit.
Most important is to make sure the poles of the battery and LED are connected right.
(usually an LED has one longer leg, this needs to be connected to the + pole of the battery)
Be carefull with the soldering fumes...
When you are done soldering, test the circuit by mounting the battery.
The LED should turn off when you hold the circuit upside down.
