Work Night 1.24.19

Work Night
Date: 1.24.19
Location: Logan HS
Time: 4:30-7:30 PM
Students: Paige, Alex, Caitlin, Seth, Avery, Tanner, Thaying, Nathan and Thomas
Goal: Determine the types of motors to order for the generation system.

Quite a few things going on tonight with some ups and downs. That old saying, "Failing Forward" comes into play here.

Alex made good progress on soldering the charging circuit together. He also printed off a spreadsheet for the MGTR.

 Avery took a longer look at Reactive Native App which uses Java Script vs Android Studio which is Java based for our cellphone app interface. We are lagging behind in the software area as we are still trying to determine what App to use. Caitlin still has to take a look at Reactive.

Paige worked on the MGTR poster boards. They are progressing nicely with good use of color to make them stand out. We need something that shows we compared piezo to electro mechanical. On the financial end, Tanner worked on spreadsheets that would illustrate our expenditures. We need to practice the presentation this week. Nathan worked on t-shirt design.

Seth worked with the thermoplastic adhesive we got from Necal. He cleaned up the surfaces and tried to apply the adhesive after heating it to over 250 degrees but we could not get it to stick. We need to call the chemist to get clarification on how to apply the adhesive.

Thomas tested the motor output on a O-Scope to see duration so we could make a decision on the motor purchase. We got a confusing output that indicated we might have a bad motor or linkage. We need to improve the linkage as it is bending on the compression step. It appears to oscillate so we may need a dampening device added. This is disappointing as we really wanted to order the motors tonight and mount them with the new gearing.

The math indicates that the current motor plugged into our charge enhancement system will  fully charge the Smart Puck in 14 hours. This is not a good output, but when we add a second motor, it goes down to 7 hours...a third motor 3.5 hours and a fourth motor is 1.75 hours. You can hopefully see the potential here. If we can also improve the mechanic in our linkage to the heel, we may see some very short charge times.
