First Ever RokkinCat Hack 'n' Tell

October 29th 2014

Last Saturday, October 25th, we held our very first Hack ‘n’ Tell at the PKWARE headquarters in partnership with PKWARE and the MSOE FIRST Collegiate Robotics Organization. The purpose of this hackathon was to hang out and team up with other developers and designers for the sake of making things.

There has been an influx of hackathons in Milwaukee lately but none that focused soley on the process of creating. We wanted to create an environment where developers and designers of all levels could spend eight hours to build anything they wanted without requirements.

A lot of the ideas that were produced would not have made it through a hackathon where the primary goal is finding a successful business model and validating customers. The outcome was even better. Developers and designers were being creative, building, learning, and just simply having fun. We thought the event was successful enough to warrant another one, so if you’d like to help organize or sponsor, please email [email protected].

Here is a list of projects that were presented during our “tell” portion of the event. (If you attended the event and want any of your information changed, please email [email protected])
