For making the final design, it took about three months to design, make the prototype, write the firmware and test it. The final product was according to the given requirements.
The design took about 16 months to get designed, prototyped and successfully tested.
Some of the main features of the final product included the followings:
The PCB size requirement was met according to the given size with an even less thickness of 4mm that made its enclosing into the scissor’s handle easier.
The power management was done by using a battery management IC and within the firmware so that during the normal operation of the system, the power usage would be minimum.
The final design took about 6 months to get completed. Due to some changes in the original request, the firmware took most of the work time to meet all the given requirements. The final design was locally tested at the client’s location and was satisfying for him.
The final prototype took about 6 months to get completed and was submitted to the client to be used in the main design. The final design also included different modulation options. The modulation subsystem combined the output from the three frequency generators and output the final output from the PCB. This subsystem could support these programming features:
• Modulate only Frequency Gen1
• Modulate only Frequency Gen2
• Modulate only Audio Gen
• Modulate only Frequency Gen1 + Frequency Gen2
• Modulate only Frequency Gen1 + Audio Gen
• Modulate only Frequency Gen1 + Frequency Gen2 + Audio Gen
The design was made, prototyped and delivered to the client in 5 months. The technique used in the design provided a highly efficient and reliable system for covering a wide area and even more distant points. The design proved that it could be used as a reliable rescue device in mountainous regions where the normal communication between cell phones are interrupted. Having checked the design, the client was quite pleased with the final outcome as it met all his requirements.
The design was made and prototyped and delivered to the client in one month. She was quite pleased with the final outcome and made the following feedback on the work.
“Ami from MEEE Services was very communicative and easy to work with on making us a wiring diagram, and answering any follow-up questions we had. Thanks for the support!”
After about 8 months of close work with the customer, finally, a fully functional prototype was prepared and tested. The final prototype met all the requirements and was later submitted to the client. Due to the use of a low-cost GPS module for the testing purpose that had low-accuracy, the response time was low, and so the motion of the camera was stepwise. However, once the client changed the module with a high accuracy module, this issue was resolved considerably. While the final setup could be improved and enhanced in terms of the response time and also its range, the work was satisfying and met the requirements.
The work took about 4 months to get completed. During the course of the work, and due to the request of the client for new features for the design, it underwent several changes which extended the original timetable. The final design was quite satisfying for the client and was submitted to the client for the prototyping.
