Emmaline's hobby site

built with a group for an ECE hackathon. Given potentiometer input to an Arduino, a motor could spin one of the wheels foward/backward. The electronics were never secured and we were too scared to try to ride the skateboard though.

I learned to use laser cutters for the class 15-394 Intermediate Rapid Prototyping. I made a circus-themed automaton and a single key model of a typewriter. Both were intially CADed in Solidworks and then cut and assembled. For the automaton I learned to create sketches from images of silhouettes. For the typewriter model I played with linkage dimensions to find something that worked in CAD, referencing this video, but the physical assembly ended up getting easily stuck, so I maybe should've looked up actual working linkage dimensions and used something better than bolts for joints.

designed, modelled, and animated in Autodesk Maya 2020 as part of an intro to 3D animation course. I also used Vuforia and Unity to put the animation in AR. I'd love to figure out how to add light/smoke effects when the dog jumps.

If it looks off it's because I free-handed all of the bones. This good boy is held together with friction, careful balancing, and hope. Future note: Use an xacto knife, not scissors

first thing I've ever modeled (in SolidWorks) and 3D printed. The inside has 6 rooms with very minimal furniture (couches, fireplaces..). Neat thing about this model was the texturing of the roof done with a picture. The 3D print was painted by my sister!

a girl model made with Autodesk Maya for an animation by my robotics team. She was the first humanoid model I had made (which is why she looks rough), and the first model I rigged. My inspiration was the Mario character.

Please believe me when I say this is a half-minute animation with multiple dancing elves (and my family members' faces on each of them), but I didn't want to post the full video here. A second rigging and animation project!

can't remember where I found the tutorial for this rubberband gun, but I taught a few friends how to make this and we named it a pewpew

built with a group in an Intro to Engineering class (the CAD drawing was provided). It's probably 90% glue and 10& file folder (but it's pretty strong!)

designed, modelled, and animated in Autodesk Maya 2020, video compiled in Da Vinci Resolve 2016. I wanted to capture a peaceful moment, while learning to model wire, animate cloth, and create god rays.

(dislaimer: I still don't know much ASL unfortunately) My friends and I translated most of "My Shot" into ASL as part of the class 98-244 Sign Language Through Pop Music. I don't have their express permission to make the video public but if you ask me I can show you!

I learned to make these 3 projects in 24-204 Intro to Metal Jewelry at CMU. The ring was my favorite - it's bronze, made through a lost wax casting where we made the ring out of wax (see the last pic), poured plaster of paris around it, melted the wax out creating a plaster cast, then poured liquid bronze in to fill the mold. The other 2 projects were earrings and a bezel pendant.

I spent a few hours every day for 1.5 weeks building this tribute to quarantine life. It can spin horizontally, but doesn't shoot and the legs are fixed unfortunately. It's also a can holder? I just used a lot of reference images and drew things out, so CAD may be useful but not necessary for these builds - measuring with proportions from images seems good enough.
Also, to create a cylinder with a beveled edge, I made a normal cylinder, cut out a target shape with 2 concentric circles, cut 4 lines from the outer circle to the inner, trimmed the outer circle between the cuts, and forced it together.

helped build this Metal Earth model I got as a gift:)

built with a kit from Rokr

made in my 3D design class with a crest I designed

my newest Metal Earth model. Tools included pliers, flush cutters, and a toothpick at one point (and my finger nails). A technique I figured otu for the rounded surfaces is pressing the metal around something already round, like a bottle. The model took 3 days, ~4+ hrs a day. I was scared of scratching the paint but I love how it turned out. Looking forward to building Hogwarts next!

A hackathon project built with my friend. A Raspberry Pi displays a laptop GUI for controls, and sends controls commands to an Arduino, which spins the motors. We originally intended to place the robot inside the full styrofoam ball, but its center of gravity was too high and it tipped over when placed inside. It was a lot of fun to make, but perhaps could've been better planned.

made as gifts. presenting Fishers, Bread, bally owl, and Ballfred

Takeda is a yari ashigaru stormtrooper modeled in Autodesk Maya and 3D printed as a gift. It took 2 test prints before being successful (I really messed up the scale in the 2nd image)

made as a gift based on a beloved pet. This is another project with more glue than it should have (hope my Grandma's proud anyway)

Mark 42 Iron Man cardboard helmet made referencing this video. The rest of the armor to come??

a character made with Autodesk Maya for an animation by my robotics team. It was eventually rigged (but not by me).

had to jump on the bandwagon, but also had to stay cheap
