Vending Controller

This collaborative project was to build a vending machine essentially from scratch. Atrick architected the controls, robot design, communications, mechanical design, UI / UX, lead design reviews, and trained the production team in assembly in all disciplines.

This hardware was made during the first months of the chip shortages. There were about 4 revisions made before going to manufacture because of the rolling chip shortages. We were very lucky to get the required microcontrollers and supporting chips. Some evolution path components were not populated due to the shortages and lack of availability.

RS-485 was used for communications and to be able to integrate with existing hardware. 3 modular control boards were made. Some served double duty to run different configurations. 1 firmware was written (by a collaborator) to work with the addressing to identify which board was which and carry out its assigned tasks. All IO are static and short circuit protected. The project was completed in the timeline Atrick gave at the start.

Industrial Controller

The scope of work was to refurbish and evolve a prototype done by a local competitor, improve functionality, UI, UX, and overall design of the machine. This controller used a Linux small board computer and visually showed all normal operational parameters in 1 view. Settings were available in 2 different menus for user and service adjustable settings. The user menu added input and output test functionality to check operation. All digital IO's have indicator LEDs to allow for easy troubleshooting. The BOM cost was reduced by about half and took assembly time of controls and harnessing from about 30 hours to about 3 hours. All sensitive parts were socketed for quick and simple field repairs.

Steppper Controller

This was a personal need for a rotary weld positioner or handheld roller. It runs a stepper motor at adjustable speeds and has an optional step back function with both adjustable time between reverse and a reversing time. This is to give welded parts a consistent "stack of dimes" look. Inputs are static protected and current limited. It uses an off the shelf stepper driver chip.

Exercise display

This was a product evolution project. Keep the existing look of a problematic display that ran on an Arduino and evolve it. The assembly time was reduced by 15x, static and reverse polarity protection were added, power consumption was 8x as efficient, BOM cost was reduced by 7x. The new design eliminated all of the issues.
