What are the steps in making mechanical chalk dust dispenser?
1. Set up an inclined tray below the blackboard resting freely at the upper end and hinged at the lower end. The chalk dust will fall in the tray and start sliding down into a waiting bin As the chalkdust may not always slide down into the bin you will need to jiggle and shake the tray a bit from time to time 2. So set up a low powered electric motor with a slow speed reduction gear attached to an eccentric disc under the tray such that the eccentric disc touches the tray at the upper end. 3. Every few minutes the tray will incline and decline like a rocking horse 4. Design the inclination angle such that the chalk dust freely flows at the highest inclination required
