Current State of Affairs

Brad has built some custom boards with PCA9554N I/O Port chips on them. There is an input board, with 22 screw terminals to be connected to any buttons on the device, an output board, with 22 relays to trigger the 22 motors to vend products, and a rPi to handle i2c protocol between the PCA9554N chips. -Jared

As of August 25, 2015, the I/O boards and RPI can successfully trigger each motor individually, and code has been written in python on functions such as tablature, stocking, and interpreting I/O boards. (Thanks Hunter!)

Gary has built a first-run prototype of a transparent coin acceptor that will pass coins in front of the glass display on the front of the vending machine.

To Do

• Hook up screen to RPI, and mount inside vending machine chassis.
• Modify Gary's coin acceptor design to work in the machine.
• Collect stock of the kinds of supplies that LVL1 wants stocked in the device.
