Hello, all !!

This is my electronic version of my another Instructable Magic Card and including new features (see VIDEO).


The original version shows the same cards but on this original version you have a lot of different combinations of cards.

It is a very simple assembly and the result is amazing !!

To play, just think on some number (from 1 to 64) and start to answer the 6 questions (Yes/No).

You only say yes or no and press the corresponding button to confirm the number you have imagined.

After your six answers, the number you have chosen will be shown blinking on the display !!

You can even repeat with same number, but you will see that the answers will be different !!

How can be this possible ?

Enjoy it and send me your comments !

Best regards,

LAGSILVA
