This week I connected the step down converters for our light and revised the power diagram to power the 50W light instead of the 100W light we originally received. This is because it is more compatible with our current drivers. I also did research and placed an order for current drivers which also include a PWM pin for control of our light from the Arduino. I also prepared slides and materials at the beginning of the week for our interim demo. My progress is on schedule since we are still working on integration and fabrication together this week. Next week, I hope to get the LED connected to the Arduino and have control over DMX from the controller to the LED. In addition, I hope to have everything that is already fabricated to be able to run off the power supply we have, so things can slowly be put into the base. If we are able to finish the fabrication and integration of everything in the head of our light, then I also hope to begin soldering the components together.
I have already done some preliminary testing. My testing has included verifying that there is RGB and brightness control of the LED, that the fans of the light and power supply are below 50 dB, and that the power draw of the components is as expected. In addition, I have checked that the voltage and current of the objects matches what we expected to receive from datasheets. For future testing, I will verify that the cooling, light and power system meet our design and use case requirements, I will conduct the tests described in our report. To ensure that the light is bright enough, I will check the lumens output with a light meter app on my phone. To check that the light has RGB control and brightness control, I will run different color combinations on out controller and visually inspect that the individual red, green, and blue LEDs can all be controlled. In addition, to test that our cooling system meets the design requirements, I will check with a decibel meter on my phone that the noise level is below 50 dB Finally, to check that the power system meets the requirements, I will check that all the components are able to run with the power supply and that it is able to run for at least 2 hours.
