2018 Robot
Intake Mechanism
Built for our 2018 competition robot, I designed this intake mechanism to use 3⁄4-in bore, 2-in stroke double acting pistons to provide resistance and support for collapsing arms along the horizontal plane. With two layers of 1⁄4-in CNC-milled aluminum 6061-T6 plates, the mechanism was designed to withstand high speed crashes and altercations. Along with 2 Vex 775Pro motors, 3 4-in 35A durometer compliant wheels were used on each arm to provide just enough give to grip a fabric-covered crate and bring it into the machine. Attached to the custom built brackets at the tail-end of the mechanism but not shown in the model was a 174.9:1-geared motor with a stall torque of 16.2 ft-lbs used to rotate the mechanism vertically 90° when not activated. Of 53 total official matches, the mechanism never failed and suffered deformation due to impact only once.
Evo Slim Gearbox Add-on Stage
Built as a custom lightweight add-on stage for the Andymark Evo Slim 4 RedLine gearbox, it was machined and attached to the gearbox powered by four Vex 775Pro motors. The stage further reduced the gearing ratio 1.5 times.
2017 Robot
Shooter Mechanism w/ Conveyor Belt
This mechanism was designed and fabricated to play a role in the 2017 FRC competition game. Designed to fire 5-in wiffle balls up and into a 10-ft tall tower, the mechanism was powered by a dual-Vex 775Pro motor planetary gearbox. The flywheel was a .5-in aluminum 6061-T6 hex shaft with 8 0.4-in wide, 2.875-in diameter 40A durometer wheels bordered on either side by 2 steel gears attached to increase mass and inertia, preventing the loss of speed as the balls were consecutively fired. The conveyor system used 2 9-mm HTD timing belts powered by a single planetary-geared Vex 775Pro motor to send the balls into the firing mechanism. Although used only twice in the season, the mechanism averaged 80% successful shots.

Web Dev
Various Org. Sites
FRC 2601 - Steel Hawks Site (old)
This site was developed from scratch using some bootstrap css, but mostly direct CSS and HTML frameworks. Some PHP was used to include multiple editable files in one, but the site mainly consisted of HTML, CSS, and JavaScript/JQuery frameworks and functions. The purpose of the site was for it to be used as a source for updates on the team and to showcase the team's work over the years.
Amaana Hands, Inc.
This is a site I developed for the non-profit charity Amaana Hands, Inc. using my knowledge of HTML, CSS, JavaScript/JQuery, and PHP, along with a WordPress installation to make it more efficient. The site gets hundreds of visitors each month and accepts thousands of dollars in donations every year. It has been well-received and appreciated as an aesthetically pleasing alternative to the previous HTML-only site and paper forms.
