MOCK UP
We built a mock up for the Projectograph onMonday. Having a mock up was important forus because it is extremely hard to explain thelogic before we have working model. While it didshow the idea behind how the device would work,the motor simply was not strong enough toproduce any decent results. We learn that we would need more powerful motor for the finalproduct that we expected. So we are taking it intoconsideration.
RESEARCH
We conducted extensive research onprojectors, LED displays and LCDs. Although allthe mothods have their pros and cons, we foundout that refresh rate was the most importantdecision factor. Because the preconception wehad for a necessary refresh rate was actually about10 times smaller than what we actually need. Inlight of this, we began researching fasterprojectors and started moving towards looking atLED displays and LCDs that have a higherrefresh rate ( 120-480hz ) because they are muchmore economic even faster than projectors. According to the market research so far, these are viable options for the Projectograph.

DESIGN
We came up with the initial design of theform factor. Currently we are contacting BenCarter who fabricated the form factor for the 5thSuit( WMS ) last semester. It is expected to take 4 weeks for design finalization and 1 week for himto build from the experience working with Benlast semester.
