FRESH box 1.0 Beta complete!

Hey Everyone,
This weekend, we made our first prototype ice box! We bought materials from Home Depot then got to work at the Hillel center, where we used Jasons awesome power tools to build our box. Below are the pictures of our progress.

We began by cutting the lexan panes so as to make an 8"x8"x8" cube inside that would hold the vaccines:



Then we tried to cut the polystyrene, but the wire cutter would not work, as the wire had an enamel coating on it...So we tried to burn off the coating:


Then we decided to use the circular saw to cut the insulation, and it worked really well. We then embedded the lexan panes into the polystyrene and secured it with liquid nails:


Next, we put the rest of the insulation around the inside lexan cube and made a top to fit the box:



Finally, Sahil and Jason finished the box off by putting the corrugated plastic pieces around the outside:


The building team made really good progress this weekend. By building the box, we found out how to use all the tools, what works, and what does not. Now we can use this box to simulate ice box experiments that will model our actual final prototype!

New semester!

Well, Team FRESH is now in their final year - seniors! The project largely needs to be wrapped up by the end of this fall semester, leaving a couple of months for writing and tying up any loose ends. The summer was marked by a couple of changes. I moved lab and family to San Diego, which was a chaotic experience. Fortunately, both Team FRESH and Gemstone staff were supportive of and flexible in dealing with this adventure. (Thanks!) I'll continue to mentor from afar, and Gunja will take over the in person mentoring every other week. After some minor technical difficulties the first two weeks (one which was my fault and one which I can blame on some poor SDG&E worker in Arizona, who blacked out San Diego, parts of Arizona, and parts of Mexico!), weekly meetings are also in full swing. The new syllabus reflects ambitious, but realistic goals to wrap up the project.

The blog should be updated more regularly now that the semester is going strong. I continue to have high hopes! Good luck!
