Adjustable Fin Design (Hardware)

Devlog #2 - CAD Basically Complete

Today I’ve basically finished with the CAD for my project, this did take a few days but I didn’t start posting on stardance until yesterday.

Changes:

• slit for motor to fit into hull
• more space for eletronics
• slit for wiring to work
• fin shape changed to be more round
• fastened/revolute mates fixed
• cap adjusted to give more space
• static fin replicated on other side
• adjusting mounting to account for servo horn

Only things that need to really be done now are seperating the components for 3d printing, and making a mount for the servos.

I DIDN’T MAKE THESE COMPONENTS
Breadboard
Raspbery pi
Servos: https://grabcad.com/library/micro-servo-sg90-9g-1
Servo horn: https://grabcad.com/library/mg90s-9g-micro-servo-medium-horn-12-holes-1

wasnt able to post this earlier bc of technical issues but we’re finally here…

over the last few days i’ve made this beauty, which essentially is a rocket that will tilt fins based off the angle of attack of the rocket, w/an accelerometer in that top breadboard part

for today, i simply just made some extra space for the components and finished modeling the hull with the servo/the horn included (since i forgot to make holes for those)

the goal with this project is to eventually do a live fire test with actual components, but that’ll definently take awhile since im still new to this whole thing

ps: i’ve spent way more than 24 mins on this project.. you can check my yt for the timelapses
