Mechatronics Engineering: Wi-Fi Pager
Mechatronics Engineering: Wi-Fi Pager

Contemporary restaurant pagers usually use radar-based pager systems that do not sync with the restaurants digital information infrastructure. This creates problems with calling certain patrons and having to keep paper records at the front desk. I sought to create a Arduino pager which interfaced directly with a computer or smartphone.

The pager has a static IP address, and the mobile application makes an HTTP request to the pager to turn it on or off. This is the first iteration of the design, for future iterations the aesthetic of the packaging would be improved, the vibration motor would be softer, and the charging would be done with prongs that allow for stacking of the pagers (much like contemporary pagers.
A PCB was designed to interface between the motor drivers, LEDs, ESP micro controller, as well as the power and switching systems. The ESP 8266 was selected as the micro controller for the project due to it's cheap cost and it's access to TCP/IP protocols.

All programming was block based, however all it does is send an HTTP request to the router it's connected to, which toggles the pager system. In tests it works seamlessly with no latency.
3D Printed Parts
3D Printed Parts
Although simple, the first iteration that was designed utilized 3D printed PLA parts. I designed and fabricated the parts on my printer, then sent them to my partner to have the electronics assembled.
I personally designed all the software and did all bug testing on the pager. If you want to read the source code, or read the full report, click here. After market testing, I determined that I would need to build software that can compete with the existing restaurant software infrastructure, and I am not that talented of a coder yet. However, in future I may look at this project and present it in more of an entrepreneurial light.
