make 3d case

i used autodesk fusion360 for making the clementine 3d case!! i was planning to use a sphere and cut it in half to make the clementine shape, but that didn't really work in fusion and i couldn't figure out how to make that after several different tutorials. also it would probably be weird to 3d print. i ended up changing the design and using several cylinders instead of an actual sphere to make the design better. i think it's very good! and i think it looks pretty cute. the 3d modelingn took a while in all, but it was worth it.

make bill of materials

i searched on digikey for the actual components that would match and fit on my PCB and made a bill of materials for me to buy later. i had to change some of the footprints on the PCB too because some parts didn't exist properly on digikey; it was sometimes annoying but after some time i figured it out yay.

fix schematic / route PCB

i found some issues in the schematic with the power system, sob

i changed the boost converter to MIC5219 instead, which converts the 4.5v (of 3 AA batteries) to 3.3v. it took me some time to choose what power regulator to actually use, and ended up finding that the MIC5219 would probably be best.

also i spent a while routing the PCB! this part was easier than i expected actually.

assign footprints

i worked on finding the rights footprints for all the components by looking at the data sheets and things of the parts.

also made a very rough bill of materials basically just searching online for the parts

finish schematic

worked on making the schematic and making some changes to the original design. i had to add the power converter & audio amplifier after some more research. also, i learned to properly use labels which was SO helpful (it was super messy before)

main challenges were in the beginning all the wiring because it was super messy and confusing, and then just figuring out what actual components i needed and where to wire them to.

brainstorm/plan/sketch

i brainstormed what features i wanted the clock to have, the actual components i wanted to include, how they would be configured, and drew a sketch of what it would look like.

the clock would be able to set alarms and timers. it has a display for the time, and then a rotary encoder and some more buttons. it would be powered by some buttons batteries. the case is 3d and spherical and looks like a orange.

i just used notibility and sketched what i thought.
