Tartan Spray Paint 15 Jan 2019, 8:58 p.m. EST
1/14/19 (Monday) - Tested hardware: ran motors, sprayed paint can for reference. Fatima Basit, Louis Plottel, and Rachel Hsin (hardware team) built prototype mount for one spray can using scraps of wood, one large nail, rubber bands, duct tape, fishing line. Wired motor to Arduino Uno, tested using test code from Mina Nowroozi and Tina Wu (software team). Hardware team tested different lever arm lengths to find shortest possible arm that motor could reasonably handle and finished off the night by making CAD to laser cut a complete prototype for a total of sixteen cans in the same assembly. Software team tested and calibrated ultrasonic sensor for returning y-axis position of device. Also developed algorithm for creating tartan pattern when spraying paint arbitrarily.
