Background: Sola Gratia Farm is a community-based farm dedicated to producing locally-grown, high-quality, natural produce. Responding to the Gospel, the farm is committed to helping those who lack adequate food resources by donating a minimum of ten percent of its produce to support regional hunger programs.

Problem: Currently Solar Gratia Farm pulls power from the church located to the south of it. Because of this, the entire farm is powered off a breaker that is connected to the church’s. Sola gratia wants to add a third cooler but it will overload the amperage of the ameren line that connects from the grid to the church. Adding another line will put them on the grid as their own service line, but they don’t prefer it as they would have to pay for their electricity(instead of the church), and it could potentially expensive. It’s our task to help create a plan once they get more money that will allow them to add the third cooler without overloading their line.

Solution: Now the line has a capacity of 75A and found that when running all we reach 34-35A, but when adding a third cooler and turn all on we reach more than 75A overloading the line for a moment. To reduce this peak during the initialization we have thought on using a Variable Frequency Drive to avoid increasing so quickly the demand of power. We have also planned to add solar pannels to reduce the power needed from the line and including some batteries to store the extra energy in order to use it during the night or eventually sell it.

Criterion of success: Develop a theoric design of the current elctrical system to fulfill all the previous requirements and finally be able to include a third cooler to be implemented when economic capital be available.

LED Cube

Featured Project

LED technology is more advanced and much more efficient than traditional incandescent light bulbs and as such our team decided we wanted to build a device related to LEDs. An LED cube is inherently aesthetically pleasing and ours will be capable of displaying 3D animations and lighting patterns with much increased complexity compared to any 2D display of comparable resolution. Environmental interaction will also be able to control the various lighting effects on the cube. Although our plan is for a visually pleasing cube, our implementation can easily be adapted for more practical applications such as displaying 3D models.
