Designing a Waterproof or Submersible Electric Vehicle Propulsion System

The term “waterproof” is very open to interpretation much like the word “natural” is in the food industry. Luckily the IPXX rating system was created to set a standard for Ingress Protection. The first number 1-6 is the degree of protection against dust/ solids and the second number 1-8 is the degree of protection against […]

Using Force Sensing Resistors (FSR’s) as a Replacement for a Throttle

After visiting many sports equipment factories we had the idea of an electronic bike grip that doubles as a pressure sensitive e-bike throttle. Similar technology exists on treadmills in the form of conductive rubber pressure sensors (no not the metal pulse sensors, the other safety fall sensors.) The idea is sort of the opposite of […]
