Robotic Beverage Handler
Designed for an applied circuitry class project, the “beverage handler” is a 3 axis robotic arm that has an Infared contactless temperature sensor that reads the temperature of a beverage, and if cold enough, the arm is programmed to follow a simple set of instructions that will grab the drink it measures, and hands the user a drink. This project displays engineering design, basic coding and programming through a microcontroller, soldering, and better understanding of manufacturing procedures.
Recovering Copper from Malachite (Copper Carbonate)
By dissolving the mineral malechite in hydrochloric acid, a green Copper II Chloride solution is produced, with carbon dioxide and water being produced on the side. From here, shooting a great deal of current through the solution causes electrons to be supplied to the ionic bond between the copper and chlorine, which then causes the copper to be reduced and no longer need bonding, and chlorine gas to be attracted to the positive anode due to the gas being an anion. This allows for the (rather inefficient) collection of copper, and comparing this case to simply adding aluminum foil to the solution shows not only the volatile nature of aluminum, but the difference between a spontaneous and nonspontaneous redox reaction.
