SunSPec 5 - Telemetry System

Final Presentation + Demonstration As seen in the picture, the blue box is to be placed within the Solar Car, whereby sensor data will be transmitted to the dashboard within the solar car via Bluetooth, and to a PC in the Chase Vehicle via LoRa. Figure 1: Telemetry System Passing on Telemetry System Explanation Conclusion We spent most of our time learning and testing out the new approaches to the Telemetry System, to finalize the transmission components to use, and were only able to come up with a basic base Telemetry System. 

We spent the week preparing for the poster, report, and the presentation. While doing so, we also made a laser-cut acrylic box to hold our circuits for better visual during the presentation. First Attempt Originally planned on building a circuit case for the Bluno circuit. Two separate cases for a Bluno circuit and a power bank. We had our first unsuccessful attempt at building a case   Second attempt We faced many challenges such as last minute realization that the USB cable head was too long with the power bank. Different cable was used to fit it together. The tapes were used temporarily to hold the case. The final attempt would be done using a better mean.

MDP Poster We started the making of the poster that would be used together with our completed circuits to present our work done to the assessors. With the given template, we decided to showcase an overview of the Telemetry system with a brief description of each individual components.  Figure 1: MDP - Telemetry System Poster The poster would be vetted by our project supervisor and co-supervisor. The printing and framing of the poster would be done next week for the final showcase.  MDP Report  We were also tasked to complete our MDP report. The report was to detail all of our process from start to finish. to be submitted next week on Week 17. Finishing the report and constantly editing mistakes being made by John (a fake name is used to protect his identity).  Undocumented experiments When first starting out, we had experimented with other components that we didn't get to mention.

Fabrication of case for circuit mount The first task on the agenda is to build the cases for each circuit mount. Each circuit mount would be enclosed by the case for protection and for better presentation. A sliding lid can be removed easily to place the circuit mount. Originally, we had planned to 3D printed the case and drill a hole in the lid for the Lora antenna. However, the time that the 3D printer would have taken is too long and we are currently looking into laser cutting for a more time effective method to building the case, The next available timing for the booking of the laser cutter would not be until 8th February, as such we are putting the fabrication of the case on temporary halt. Testing of LoRa With the LoRa circuit done up simulating the Solar car and the chase vehicle as shown at week 13, We finally are able to test it on the road with the help of Mr Kenny and M Chua (and their cars).
