This week I received items for the motor/mechanism parts of the project and started investigating how they will go together physically to create the system. I started writing code and hooking up the motors and motor drivers. We are thus far on time with our project and hopefully will continue to be on time as we get closer to the break. In the upcoming week, I will continue to get the motors working with their drivers and code and continue to develop the CAD for the system.
Team Status Report for 2/21
This week, our team continued researching and ordering components for our moving light. Kira presented our design review slides, and we all completed peer reviews for other team’s designs. Ella made substantial progress on the motor subsystem after key components arrived midweek, allowing her to begin more hands-on work. Chloe began drafting our design report, using the provided template. Next week, we plan to focus on completing the design report, finalize component purchases, and Kira and Chloe will begin developing their subsystems, DMX I/O and cooling respectively, as long as the necessary components arrive on time. At the moment, the most significant risks would be the delay of parts arriving, or realizing that the parts we bought are not compatible with each other. To minimize these risks, we’ve looked carefully at the specifications of all ordered parts and only ordered what we needed to get started, that way we can make adjustments as we go if needed. This week, our design hasn’t changed much, since we’ve nailed down almost everything while preparing for our design presentation last week.

This week, I helped Kira, our presenter, prepare for the design presentation. In addition, I started on the draft of our Design Report using the provided template. In addition, I ordered the parts needed for our lighting and cooling system so we can start working on it next week. For the power system, I wasn’t able to finalize the parts needed, since I am still looking for a good AC/DC converter that provides enough power while also being small enough to fit inside the base of our light, along with the other components there. My progress is still on schedule, since I was planning on having the power system fully designed out after spring break and for the lighting modules to be completed after spring break too. Next week, I hope to find an appropriate power converter and finish the draft of the design report. In addition, if I have enough time, I also want to start looking at the code I will need for the LED control.

This week I spent time rehearsing the design presentation with my teammates to make sure our slides flowed well and that we were clearly communicating our design decisions. On Wednesday, I delivered our design presentation and answered questions from classmates and instructors. In addition, I ordered the necessary components for the DMX I/O subsystem and finalized which Arduino I will be using for development. I also completed all remaining setup and preparation work so that I can begin implementation immediately once the components arrive.
Team Status Report for 2/14
This past week, we worked on spec’ing our design and ironing out the details surrounding exactly how we will be accomplishing our project. We placed our first orders for items like the motors and parts for the mechanisms that will handle our pan, tilt, and focus. We also did research into different lens and LED options that we could use, which is still ongoing. Along with researching the LEDs, we are researching how to best handle heat in the system, which will be affected by the type of LEDs we end up selecting. We also continued our research into the best way to implement our DMX communication protocol.
Since we’re still early in the project, the risks are still things that we are planning for. The most significant risk that could jeopardize the success of our project at the moment is likely running out of time at the end due to unforeseen issues. As of right now, we are planning how to handle the challenges that we foresee, and everything feels pretty under control as long as we can stick to our plan. However, if later in the project we discover an issue that stalls our fabrication time, that could jeopardize our success. To mitigate this, we intend to stick to our schedule and get things done with plenty of time to do unit testing and integration, while also budgeting buffer time to address any unforeseen issues that may arise. We intend to make our system very modular so that if we do have an issue with one part of the system, we are easily able to remove and replace it if needed.
Our design has largely remained the same during this past week, but we have gotten a much finer level of detail for some of the systems and how exactly we will achieve our MVP.
It is also important to consider how the product solution we are designing will meet specified needs, including public health, safety and welfare factors (A), social factors (B), and economic factors (C). A was written by Chloe, B by Kira, and C by Ella.
A. For our project, some safety considerations included weight, size, and temperature. Because this is intended to be used in an educational setting, where there may frequently be one teacher responsible for the lesson, we wanted to make sure that our light is easily managed by one person. According to OSHA standards, a safe lifting capacity for a standard adult is 50 lbs, but drops down to 20lbs when the object is more than 25” away from the body. Keeping this in mind, our light will weigh less than 30 lbs, and be no larger than 24” x 24” x 24”. Therefore, we are well under the 50 lb limit and the light will be less than 25” away from the body. Aside from size and weight, temperature is also important to consider. Because users may be touching the light while it is in operation, we wanted to ensure that it would not burn anyone. Therefore, we are designing our light to include a fan that turns on to cool the light when the temperature exceeds 35°C, which is when objects feel hot to the touch.
B. Our product is designed to be both affordable and educational, which helps address social factors like access to technology and collaborative learning. Many student organizations, schools, and community groups operate with limited budgets and rely on shared technical knowledge rather than specialists. By selecting widely available components and using open-source resources, we are creating a system that these groups can realistically understand, use, and learn from. This approach encourages technical literacy and confidence while making the system approachable and practical for a wide range of users in educational and community settings.
C. When considering our product, economic factors are a key aspect to our MVP. One of our leading goals with our product is to create a miniaturized version of a very expensive professional, commercial product, with the intention of bringing this technology to groups that may not otherwise have access to it. Specifically, we want our product to be accessible for educational settings, specifically schools that may not have the budget to spend tens of thousands of dollars on moving lights and lighting consoles. Through our design process and part selection, we’ve kept this in mind and selected cheaper components that still will function as we need them to. We are thus far well under our $600 budget.

This week, I finalized the materials needed for the lighting and cooling system. These included the RGBW LED array, LED heatsink, LED fan, base fan, convex lens for focusing, and a 60° lens for the light. In addition, I worked on the slides for our design review presentation and helped Kira, our presenter, prepare for it. Aside from this, I looked into AC/DC power converters, and the specific power draws of each of our components. Considering the power draws of our LEDs and motors, which will require the most, and how they will be connected, I will decide on the best converter to use. Our progress is currently on track since our Gantt chart shows that I am working on power research and the lighting module for this week. Next week, I plan to finish ordering the parts required for the lighting and cooling, and to finalize the parts needed for the power system. In addition, I plan to work on the design review report.
Kira’s Status Report for 2/14
This week I researched and selected the microcontrollers and DMX shield, adding them to our team’s shared purchasing sheet. I referenced an online technical blog for the basic DMX hardware setup, which helped guide my component choices and clarified how the transceiver and shield should interface with our Arduino. I also plan to use the DMX control library from that blog as a foundation for our software implementation. I combined my research with Ella and Chloe’s findings to develop a clear integration plan and create a full system block diagram for the design slides showing power distribution, control flow, and communication paths. I also developed the implementation slides by organizing a concise purchase sheet, citing key references such as the blog and open-source code, and outlining the modular assembly plan. Finally, I prepared my presentation script and rehearsed it with my group mates, as I will be the one presenting our team’s design slides next week.
Ella’s Status Report for 2/14
This week I designed, spec’ed, and 3D modeled (Solidworks) our pan and tilt movement mechanisms. Putting things in Solidworks was mainly for my own peace of mind and ensuring that everything will fit as I anticipated (as much as I can tell from online models and dimensions) so that I could have more confidence ordering. I also designed and spec’ed the focus mechanism, but I’m waiting to see what lens etc we choose to use before I figure out how much travel distance we need to get the focus that we want. We are thus far on schedule which is great, and I’m excited for parts to come in so we can start really getting into it. I also helped make the slides for our upcoming Design Presentation this week. This upcoming week, I’m hoping that the motors and other stuff that we ordered will arrive (hopefully they were ordered on Thursday). If they do come in, I intend to get all 3 of our steppers working. I also intend to model the focus mechanism (at least loosely / with stand-in parts). Either this week or the week after, I intend to start trying to fit our mechanisms together and designing and prototyping the 3D printed elements to make sure that we have a smooth process later on and don’t run into a time crunch down the line.
Kira’s Status Report for 2/7
This week our team presented our Proposal Presentation and continued refining the scope and technical direction of our MVP. I researched digital multiplex (DMX) converters to confirm that using the DMX protocol for our mini moving light would be feasible. After verifying compatibility and implementation requirements, we decided to incorporate DMX so our light can be controlled using the same protocol as professional moving lights. In preparation for the presentation, I developed the solution approach section and created a detailed block diagram of the system architecture. I also sat down with our presenter, Chloe, to run through a practice presentation and make final adjustments. I then continued refining the solution approach and block diagram to clearly outline how each part of the system will come together and to solidify our implementation plan moving forward.
Team Status Report for 2/7
This week, we worked on fully defining the scope of our project and what requirements are needed for our MVP. So far, we haven’t made any significant decisions that could jeopardize the success of our project. At this moment, our biggest risk would be falling behind schedule and having parts come later than expected. To minimize these risks, we have a Gantt chart we are following and have built-in buffer time for delays and debugging. Most of the changes we have made to the design this week was flushing out the details of what requirements we want our project to fulfill and how we plan to do so. We have decided on a DMX controlled light with an accompanying controller. This change allows our light to be compatible with industry standard lighting consoles and the costs of this change would be purchasing DMX to serial converters for our light and controller.
