Have a few dozen spare motherboards or PCB’s lying around? Make them into a table! Essentially, the makers took a standard table, attached the circuit boards to it, then topped it a clear transparent acrylic sheet.
The acrylic sheet is mounted on a series of clear spacers, so it almost gives the effect of floating on top of the circuits. Look closely before you design one for your home/office décor as different sized motherboards are precisely fitted together in a neat pattern. In total, the circuit board table took about 6 hours to finish making it an awesome weekend project!
