<p>Provided is an inexpensive electronic paduk board capable of recognizing the accurate positions of stones that include a transparent upper plate patterned to have 361 cross points, and a printed circuit board and a space with a support plate formed under the transparent upper plate, the printed circuit board having first and second contact patterns with radial contact protrusions at every cross point, the patterns having a connection hole into which both terminals of light-emitting diodes are fixedly inserted, the printed circuit board further including a fixedly soldered cap having an embedded permanent magnet, the first and second contact patterns being connected to each other by means of a conductive layer coated on the permanent magnet, the light-emitting diodes protruding through the central hole of the cap to emit light on the transparent upper plate through the central hole of the magnet and the through hole of the printed circuit board, the electronic paduk board further including a microprocessor for recognizing the positions of stones in such a manner that the first and second contact patterns get in contact with each other as the magnet moves up due to a small metal material embedded in the stones as the stones are set on the cross points of the upper plate, thereby allowing the user to have a game with a desired play pattern and view which point is the best for move.</p> |
