Dear Dr. Michelson,
The purpose of this memo is to inform the course staff of EECE 380 about our team’s progress during this past week as well as any difficulties we encountered.
Our group continued with our design process, working on each component of the project. Parts ordered from Digikey had arrived and we were able to test and begin implementing each components of our design. Temperature sensor was easy to be set up, which only required a load resistor for calibration. An IR emitter and a photodiode were used to transmit and receive infrared signal so that we can measure the RPM of the windmill. One problem we faced was the effective distance is too short so have to make sure they are working the range next week. We intended to power all of our sensors and actuation circuit a solar cell we ordered from Digkey. It could output a steady voltage about 6V but the current obtained was too small, which was around 60 micro-amps. Therefore we might have to go to an electronics store to purchase another more powerful solar cell.
Next week we will finish combining the main functions of Q4000 into one program. Also, we will finish implementing and integrating all the hardware components. We hope to have the two jobs done as soon as possible, as time until our deadline is less than a week and we need time for troubleshooting.
With Regards,
Chun Yeung Chow
