Work Day 12.27.18

Work Day

Date: 12.27.18
Location: Logan HS
Time: 10:00 AM- Noon
Students: Thomas, Avery, Alex and Seth
Goal: Attach the newly 3D printed generator mount and work on the electrical requirements for the buck boost circuit.

It is the holiday break and team members are still coming in to work on the project. Alex, Avery, Seth and Thomas took time out of their vacation to come into school for a couple of hours to work on the 3D mount and some electronics.

Seth modified the generator mount design after we started to attach it to the limb. We found 4 or 5 areas that needed modifications to ensure a nice fit. We called this version of the mount the Mark IV.

Alex and Avery spent quite a bit of time figuring out the best way to attach the bolts into the mount as the tolerance is very small and close. We had to countersink a hole which caused part of the mount to crack. We will build the new tolerance into the next design. They also soldered some wires to the motor to extend the range we can monitor the system from.

Thomas worked on the electrical requirements needed for the buck boost system. We know we will have a small voltage coming in so we want to create a circuit that will boost that voltage into a higher output voltage. A lot of this will be surface mount so the soldering will be finer and more attention to detail will be needed.

We ran out of time to test the system which is probably for the better as the next generator mount will be printed by then and we can use that.

learn from so we can print a better one with closer specifications.

attach the generator mount.
