Week 4: "Big things coming for my build!" he said

Progress on the project has been steady this week across multiple fronts. On the design side, I have been applying the scientific method to iteratively improve the Double Wishbone suspension assembly: printing a version, identifying what needs to change, refining the CAD model, and printing again. A few iterations have already come off the resin printer, and each one has brought the geometry closer to where it needs to be in terms of fitment, joint clearance, and structural integrity. The resin printer produces parts with high levels of detail and rigidity, enabling meaningful comparisons between versions. However, due to the print volume limitation, larger pieces such as the underbody will have to be printed on a filament printer or CNC machined from aluminum.

On the electronics side, I successfully wired the motor and servo to the RC receiver and tested them to make sure they work. I also made my first visit to a local hobby store, where I had a really helpful conversation with the person at the counter about parts selection and what components would best suit the scale and speed requirements of the project. That kind of hands-on expertise is hard to find online (looking through forums is hard work), and it gave me a lot to think about going forward. I am planning to return to the store again this week to follow up and source some additional components. They also have free pizza.
