AN AUTOMATIC WHITEBOARD CLEANER

The automatic whiteboard cleaner is a board which erases itself  at the push of a button having exhausted its surface with writings. It was designed with components which include; a marker board, board frame, a spring loaded and adjustable eraser assembly made of felt material, a chain drive mechanism and a control.

It should be noted that the control you see in the video is a knife edge switch because this was what we used during the project work but with recent modification, a well design control has been made to bring out an outstanding aesthetic in the new design which is yet to be published.

Well, if you have problems on how to design the control, just meet someone who is sound in the electrical/electronic engineering aspect to help you design a control that can power your motor (having a rectifier to convert your ac do dc if dc motor is to be used), left, stop and right buttons to control the motion of the eraser assembly, indicators made of diodes to indicate the two directions and the stop, if battery is to be used, it must indicate low battery when battery is flat and must also indicate when plugged to power supply may be with a red colour diode.
So assembling all these together with your own design look, then you are done.
