Jeffrey Jester, Balloon Professor

Jeffrey Jester, the Balloon Professor provides for this event fun and entertaining balloon twisting. His many balloon creations can include many different kinds of animals (real or mythical), super heroes, princesses, motorcycles, hats, flowers, etc. Children, and adults alike, love to be amazed by the creations of inflation that come from this balloon twister.

Sprocket Calculator

SprocketR Project Proposal

Overview:

The SprocketR web application makes it possible to generate 3D printable sprockets as a .stl or .dxf based off of a user specified gear ratio, desired center to center distance of the sprockets, and chain size. Blender via Python scripts is used to generate the sprockets while PHP to make a web interface.

Features:

lock button for fields to make field unchangeable in final sprocket
approximate button for fields to make dimension approximate
sprocket generation as .stl or flat as a .dxf
infill calculator base on torque
ability to add mounts: vesa hub, terix hub
Can generate compatible versions around a COTS sprocket
graphic web application for quick and easy interpretation

Use Cases:

A robotics team needs a better sprocket to ensure that there is no loose chain between two sprockets, and uses the SprocketR to make a custom sprocket that minimizes loose chain.
A hobbyist wants a tool to make a better sprocket
Demonstration of Blender uses

Central Texas Droids – R2-D2 Builders

We are a local branch of the R2-D2 Builders Club serving Austin, San Antonio, Round Rock, Dripping Springs and other Central Texas towns and cities. The R2-D2 Builders Club is an Internet fan based club with over 5000 members world wide. Using the web as a common means to gather information and share thoughts and ideas with one common goal… to build our very own life sized replica of an Astromech droid from the movie Star Wars.

Engineers Without Borders

Today, more than two billion people lack access to the most basic things, such as clean drinking water, adequate sanitation, reliable passage to local markets and more. Engineers Without Borders USA (EWB-USA) is engineering change in 39 countries around the world to transform this reality — one well at a time, one bridge at a time, one community at a time. Our mission is to establish programs worldwide through partnerships that design and implement sustainable engineering projects, while creating transformative experiences that enrich global perspectives and create responsible leaders. EWB-USA’s vision is a world in which the communities we serve have the capacity to sustainably meet their basic human needs.

Recently, EWB-Greater Austin chapter has initiated a maker movement to provide instrumentation needs to support its projects by utilizing open source platforms such as Arduino, RepRap 3D Printers and others. Our initiation has visibly helped EWB projects with Digitized Measurement Tools, Automation & Control Systems, Power Generation Systems, Wireless Gadgets and many others. These systems or gadgets, purchased off-the-shelf are cost prohibitive for EWB projects due to high purchasing cost and recurring maintenance costs. Closed/intellectually-protected systems also hinder EWB’s initiative to provide custom made solutions. Considering these challenges, we have strategically decided to utilize open-source and increased our work efficiency, accuracy, productivity and the overall outcome of the projects.

We are seeking visibility among the maker community across the globe to accelerate our initiative and spread our message. Presenting Engineer’s Without Borders at Maker Faire will provide us leverage and motivate makers to build something innovative for the benefit of underprivileged communities.

Uplift Desk

These electric, height-adjustable desks allow users to quickly and easily switch between seated and standing positions while working. If you’re considering upgrading to a healthier workstation, the benefits associated with an adjustable-height desk are undeniable. With an electric adjustable desk, like the UPLIFT desk series, the seamless, push-button adjustment from a sitting position to a standing position helps avoid sitting fatigue and pain, increases alertness and productivity and can help users burn more calories.
