Sparks are Flying!

Featured, Structures

As we are starting to focus on finishing up the structure of the car, we have a lot of welding to get done putting on structural supports. George, our team welder, has been helping other students on the team learn how to weld. As you can see in the picture to the right, there are […]

We’re Going to Texas!

Featured, General

Registration has been submitted and we are an official competitor in the 2019 High School Solar Challenge at the Texas Motor Speedway! Team members have been putting in hours after school and on the weekends to design and build the remaining components of the car, and complete registration details. The competition will take place July […]

Getting it Working pt.2 – Battery Driven Car

Featured, General

Invigorated by our quick process and early completion of our 1 February deadline, we felt confident that we could have our car driving under battery power within weeks. Unfortunately, fate (or the weather) reared its ugly head as snowmageddon reigned in Seattle, with several feet aggregate of snow dumped on the city in just two […]

Getting it Working pt. 1 – Rolling Car

Featured, General, Structures

Since our last post we’ve been hard at work and a lot has happened. We’ve gone from CAD models to the testing track in the span of a couple weeks, and we are excited to keep moving forward towards competition. As July draws ever closer, the pressure and pace of work has increased dramatically. With […]

General Team Update

Featured, General

The team is hard at work since returning to school after Winter Break. Here’s what we’re up to! Cutting, welding, and more! We have started to cut parts for the suspension and chassis. Students are learning how to use different tools in the shop such as the horizontal band saw, table saw, and hand saws. […]

Out With the Old and In With the New: Getting a Jump Start on the New Year

Featured, Structures

Over the week-long break, we made several leaps in progress on our way to a working solar car. Since we have not competed in this competition before, it is paramount that we iterate our design as much as possible in order to artificially boost our team’s experience. Over the course of the winter break, several […]

Chassis Design: Prototype 2

Featured, Structures

Our new chassis design has taken a major shift in its compatibility with other parts and its aerodynamics. We have changed our chassis to be thinner to accommodate the change in the width of a human sitting down. At the bottom of the chassis, the inner width is 22 inches and its upper width is […]

New member of the team


General

Since joining RAHS, I have always been fascinated by the Solar Car Team. Since joining, I have had so much fun, I know I made the right decision. Instead of making models or basic design, we are making a real car that you could drive and and make yourself, this idea is so cool to […]

Lighting up our system


Electrical System

As with any street legal car, there needs to be light indicators so that drivers are able to see what that car’s driver is doing. So for our car, while headlights are not necessary, stop and turn lights are required by the rules, so that our unfortunate driver doesn’t end up getting rammed for not […]

Designing our onboard telemetry computers


Computer Systems

For our solar car, there are many requirements that we need to meet, and the many more needs to reach optimal performance with our vehicle. We need to design a rear-view camera system, telemetry displays, and a system control panel. In order to accomplish this, we will be using an array of Raspberry Pi B+ […]

Our Shockingly Good BMS


Electrical System

An integral part of dealing with lithium ion batteries is having a battery management system (BMS). The purpose of this is to balance the cells (or sets of cells) in series to ensure while charging/de-charging the load is consistent across the whole battery. We are using a BMS which includes an android app to monitor […]

Need For Speed: Solar Car Aerodynamics


Aerodynamics, Featured

The aerodynamics of our solar car are full steam ahead. A smooth body will ensure that the power from our motors is spent moving the car instead of opposing the drag. Essential elements of our aerodynamic body: Fairings around wheels Smooth airfoil shaped body surrounding chassis Aerodynamic solar panel frame and struts We connected with […]

Seating and Safety


Structures

While having a working and efficient car is important, it’s all for naught if our car doesn’t comply with the Solar Car Challenge’s safety standards.  It’s imperative that our car is safe for the driver and those around the car and so, acquiring our required 5-point harness and a good seat for our driver was […]

Building the Car: Metals and more


Structures

One of the most fundamental decisions guiding the construction of the car is the choice of materials.  The strength and weight of materials used decides the size and type of stock used to create components, as well as dictates in part what manufacturing techniques we can use.  This dependency also works in inverse, for example […]

Braking With Bicycle Disc Brakes


Structures

For the braking system, we are using  brake discs and calipers from bike brakes, including cable activation via lever. When thinking of brake design and the uniquely shaped chassis, we decided we should use the simplest braking method for a prototype. The Solar Car Challenge requires a dual braking system, with separate pedals activating each […]
