Engineering Prototype: Bike Pump Project

One of my favorite projects was creating a prototype bike powered pump. We worked with the World Bike Project and Buffalo Bikes to to prototype a low-cost, light weight, easy to manufacture, but higher efficient pump to empower developing country farmers. While prohibitively expensive and heavy treadle pumps exist, the current low cost alternative are hand-pumps. We wanted to level-up the power by harnessing the mechanics of a bicycle (a very common device), to provide more water at low cost. You can read a presentation that does an in-depth analysis to our design, creation, and analysis. I used CAD, quick prototyping, 3D printing, and many other mechanical engineering tool-kit skills,… Read More »Engineering Prototype: Bike Pump Project

ADU Garage Conversion

Accessory dwelling units (ADUs) are one of the best ways to add value to a property, especially in the Bay Area, where there is a perpetual shortage of housing. I have found that one great way to add an ADU is by converting an existing garage to an ADU. This converts inhabitable space into a complete unit with kitchen, bathroom, and bedroom.  One project I did was the planning and execution of a garage conversion. ADUs have all the complexities of a whole house, constrained by a small package. They require all the same electrical codes, kitchen and bathroom complications, and structural analysis a large house needs just to name… Read More »ADU Garage Conversion
