Private Eye Brings Some Message to You!

Hi everyone! It's Yukiko I.　Fall has come!
Autumn with the sky clear and blue, and horses growing stout. I love this season.

This month's project is for sending some secret messages. Your private eye is coming..... You've got some message. Hmm.... It is so messy and tangled so that you can't read it.

 But the private eye can solve this mystery. Push the button named TOP SECRET, then something will happen.

Have you been seen the combination set of a red pen and a green translucent sheet? That can make hidden or come out some image. I used the set in my young age for the preparation of the Exam.

This is the same theory but using the color light. This stamp image is composed of green and red. So the red light can vanish the image in red, and you can see easily the green letters when the red lights turn on.

Additionally, I use the Verostat with the switch as a DIY pressure sensor. So I can change the intensity of light with the finger pressure!　It can make a mysterious effect.

This is the circuit of this card. It is really simple. The parallel circuit with three red LED stickers. 

I use the Velostat for changing the intensity of the light. You can add a special effect with this black conductive plastic sheet. Just Lay this pressure-sensitive conductive sheet in the battery space, under and over of the battery, both are fine. This black sheet has a resistance that changes with the pressure.

It is so easy but can make an amazing effect. Check it out next movie! The harder you press, the better the material conducts, and the brighter your light shine. cited from "the Circuit Sticker Book".
