Designed from scratch to eliminate young weeds before planted seeds germinate. Centered on design-for-manufacturing: minimize welding, maximize bent sheet metal, reduce both cost and complexity.

A forklift propane tank feeds 6 individual burners. Each has a spark plug and coil controlled by Arduino for continuous ignition. Stainless steel heat shields contain flame, increasing efficiency and travel speed.

As the first prototype, outer shields were given additional bolt holes to keep all shields identical, reducing laser-cutting error and cost. A project I personally initiated and led from concept through field testing.

After observing how difficult implement swaps were, I designed a front crane allowing a single operator to lift, swing, and hook up implements far more quickly. This was inspired by the Tilmor tractor design.

Built from bent laser-cut sheet metal and MIG-welded, this design was considerably cheaper than metal tubing. A large center cutout reduces weight. A rope-and-crank system handles loads up to 250 lbs.

An FEA study in SolidWorks validated structural integrity before fabrication. The finished crane was zinc-plated for corrosion and rust protection.

Protects the driver, supports the roof, and mounts antennas at the tractor's highest point. Originally designed in metal tubing, I redesigned it with laser-cut bent sheet metal to allow flat-pack shipping, not possible with the welded original.

Three main structural tubes were retained; everything else is laser-cut and subsequently nut-and-bolt assembled. A 3D-printed antenna and WiFi router housing at the rear uses balls and springs to rotate and clear low overhangs, a passive safety mechanism.

This was a competition in our Materials of Deformable Solids (MODs) class, where we designed, used FEA, and tested beams aimed at producing ones with the highest strength-to-weight ratio, with certain size constraints. We won this competition by achieving the highest ratio of 71,000 times the beam's own weight.

After learning that the university's testing equipment was off limits, we decided to build our own testing rig. We designed and welded it out of metal tubing, then used force meters on wrenches for overall estimates before our final design was officially tested with the university's equipment. Our design also needed an incredibly rigid material, thus we used Bambu Lab's PPA-CF Engineering Filament.

After printing and testing numerous beams with 9 different overarching designs, we landed on our final one. This final beam hit all the sizing constraints and took advantage of the fact that the testing rig had angled supports to hold the beam. This meant we could match the beam's lower geometry to match it, converting nearly all the force into compression.

A half-year passion project helping campers and retreat groups understand the layout of Silver Lake Mennonite Camp. Every structure was individually modelled to scale in Onshape and printed on a Bambu Lab X1C. Everything from large buildings, to small ball bins and kayaks was included.

The model consists of nearly 500 printed parts, epoxied lake surfaces, and CNC-routed paths (Scienci LongMill). Buildings lit at night in real life have individual LEDs mounted inside, switchable as a group. Mini campfires light up giving the model an added ambiance.

Managing a complex multi-part assembly, coordinating dozens of unique print settings, and integrating wiring throughout, all while maintaining visual accuracy and structural integrity.

A 4-foot interactive periodic table designed as both an art piece and a learning tool for high school classes, aimed at creating excitement around chemistry and visualizing elemental patterns.

Each of the 120 element boxes was individually 3D modelled with a unique symbol designed from scratch. Each box includes a diffusing layer halfway through to evenly spread light from the LEDs behind. The title and LED holes were CNC routed into the plywood backing.

Shown at several schools, the table allows students to visualize properties like melting point, electronegativity, and density through individually controllable, colour-coded LEDs which are controlled by a 3D-printed box housing an Arduino.

This project started as a cardboard cut-out of a Batman logo, taped to a stick in front of a small flashlight. Once the proof of concept was complete, I was hooked and started designing Version 1 of my bat signal. The flashlight outputted 3000 lumens, and the threaded attachment allowed me to crisply focus the image.

The flashlight I used in version 1, however, was a little flaky, so I switched to a Laser Excited Phosphor (LEP) flashlight. This flashlight technology is superb at shooting great distances, allowing me to shoot this signal for over a kilometre away.

I used this symbol frequently at the summer camp to trick kids into thinking that Batman will show up, or to simply draw their attention away. I decided to print the SOS as a potential emergency signal when camping; luckily, I have not needed to use it yet.

As the autonomous tractor's control box grew more complex, debugging became harder and connections less reliable. I designed a custom PCB to reorganize the wiring, moving away from DIN rail connections and focusing on reliability and debuggability.

This was my first PCB design, mentored by professional electrical engineers. I am proud to say it was a success on the first revision, dramatically simplifying the wiring layout and improving system reliability.

Future-proofed with connections for future controls such as remote e-stops and emergency brakes, the PCB positions the tractor for expanded autonomy features.

The electrical backbone of the Periodic Table Wall Art, 120 individually addressable LEDs behind 3D printed element boxes with diffusing layers. All controlled by an Arduino.

Display modes: elements coloured by group, density, melting point, half-life, electronegativity, molecular composition, and various others. This allows students to discover patterns within the table. Scrolling text animations (e.g. "BOIL" for boiling point) add engagement.

Shown at several high schools to generate excitement about chemistry, making an abstract subject tangible and visually compelling.

At Accelerated Systems Inc., I diagnosed and repaired broken electric motors, designed waterproof motor controllers, and converted gas-powered golf carts to electric drive systems.

Additional initiatives included managing all 3D printers in the shop and contributing to the restoration of a CNC machine.

The 4-foot frame and backing were built entirely from wood. Title lettering and LED holes were CNC routed into plywood with precise positioning to align with each of the 120 3D printed element boxes.

The frame required careful joinery to stay flat and square while supporting the weight of all the printed parts. Surface finishing and painting completed the professional presentation of the piece.

Woodworking acts as the structural and aesthetic foundation for multi-disciplinary builds, providing a stable, beautiful base for electronics and 3D printing layers above it.

The camp map base is a large wooden platform with terrain features CNC routed using a Scienci LongMill, paths carved into the surface, lake areas cut out and filled with coloured epoxy for a realistic water effect.

The board frame was hand-built to provide structural rigidity supporting nearly 500 printed parts. Finishing involved sanding, priming, and painting terrain before buildings were installed.

I was tasked with designing a sculpture that could bring in the essence of fire for a church. The helical structure, combined with 41 individual candles, gave this 3-foot sculpture an eye-catching effect.

Initially, it was lit in the daytime; however, I knew that at nighttime the candles would really shine, and they did not disappoint. 41 candles burning simultaneously give a lot of light, so one could easily use this for nighttime gatherings.

Finally, to really cap off the magnificence of the sculpture, I added a slowly rotating motor below to spin the entire thing. This allowed people to view all sides of it and see the cool illusion of the candles wandering up the helix.

This handcrafted wooden toolbox was designed and built to provide a compact, organized solution for everyday maintenance and repair tasks around the house and at camp. The box features a folding layout with two stacked boxes per side, allowing easy access to tools while keeping the overall size compact.

The links for the folding-out boxes were 3D printed to ensure accuracy, which allowed the boxes to fold out evenly. The center compartments were designed to perfectly fit certain tools, ensuring they were snug with minimal chance of falling out.
