WEEK 20

Final Project Development

May-29-2026

What tasks have been completed, and what tasks remain?

For detailed notes refer the respective subheadings in this page.(which will be added later) I have trial cut few components and still working on the 3d model.

I have completed the schematic of the neo pixel ring light.

This is the Trace I drew, I used the External plugin- Place footprints. The diameter is 40mm.

I also tested the Neo pixel ring, there were issues with improper soldering, which were solved.

I 3D printed a gig to find the size for the bearing to fit in well

I designed a holder for the bearings which will run along the acrylic gear.

These are the slider and the gear

Lazer cut a segment of the gear to see if the 3d printed gear would run on it. It does!

Remaining tasks: I have to do the production part for the frame, gear and main pcb board. Then the firmware to solve.

I milled the board on Saturday.

what's working? As of now i have figured the gear systems and the above mentioned

what's not? I have to figure out how the pcb can be removed easily if there are any issues with wiring

what questions need to be resolved?The frame thickness has to be reolved by resting th eneo pixel light and the image frames. at the end of the week I have answered this, I am to build the frame

what will happen when?A lot was supposed to be over, but it hasnt, and its been pushed down. By mid next week I should be done with production and be on the firmware.

First schedule created

Second schedule

what have you learned?There are lot of minute details or events or people that demotivate us. Well on a professional tone: I have understood that one part, say the pcb design and the components placement is very important. The wires, the length of the wires , how they are guided in the product. The 3d print model for the mechanical parts, One has to understand the mechancial aspects, how vibrations might affect, what could be neglected. Here the gear fixed on the motor has to be tight press fit. The bearings also have to be tight fit. How and where the pcb will be mounted, what kind of power will be given. how it would appear asthetically.
