Cards Against Humanity Custom Camping Set

Cards against humanity is one of the best party games around – and one of the best games to play with friends when you’re out in the wilderness. However, there are numerous problems if you want to take these cards

Tilting Three Wheeled Electric Car

I’m a big fan of electric cars.  Electric motors have some major advantages over internal combustion engines: 100% torque from 0 RPM – immediate power off the line Linear torque delivery – no “lumpy” torque delivery like turbo engines or

Reference Library

How do you learn how to design and build a car from scratch? You have to become an autodidact and learn everything you can about the subject. I’ve personally been amassing a design library to help me along with this project.

Two of the main design goals of the car are simplicity and lightness. Wiring harnesses can become extremely complex and because they are made of dense metals like copper, they can also become extremely heavy. The wiring harness for the average

Tilting System

Camber Thrust Tilting the wheels of a car so that they lean into a corner (like on a motorcycle) is most beneficial because it creates “camber thrust.” Tires can develop cornering force in two ways: slip angle and camber thrust. Slip

Motors & Gearing

One of my main design goals is to keep the mass of the car as low as possible. This means selecting motors that have the most power per unit of weight. I’m planning to run three motors on the car
