    Two Cycle analysts - One Grin Tripwire

    My dual-motor ebike has two batteries and a Cycle Analyst for each one. I want to use the autocruise feature on the CA's for both motors so I need an ebrake signal to deactivate the autocruise. Can I parallel the ebrake/ground of two cycle analysts to one Grin Trip-wire?

    Hub Motor Dynamic Efficiency

    If someone can help me with this, it would be much appreciated: Using an arduino output to control throttle; what is the most efficient way to apply power to a hub motor? I've noticed when I control the throttle when pedalling normally, that my battery seems to drain faster than if I use PAS. My...

    Paralleling Motor Cutoff Switch

    I have a grin tripwire switch that I want to wire in parallel to one ebike controller and two arduino nanos. The tripwire has two wires (no V+) that must be signal and ground. So when I hook them into the controller I think there will be controller voltage on the signal wire. If so, I'll need to...

    Cycle Analyst V3 interface to Arduino Nano33 IOT

    I want to input a throttle signal from an Arduino Nano33 IOT to a CA_V3. The Nano33 IOT is really nice; small form-factor, wifi, on-board IMU and has one analog output which I want to use as a throttle input to CA. The analog output from the Nano is a 0-3.3v signal and I don't want to fry the...

    Sail, Solar, Wind Powered Expedition Triak

    This project is to build a sailing frame around a sea kayak and outfit for extended length expeditions. The snapshot is from the 3D model that I use to plan and build; looking up from under the water, with a "glass" rendering so you can look inside everything :) The boat is essentially...

    Terrain Control alternate to PAS/Torque control

    I'm working on an alternate to PAS/Torque; namely terrain control. I live in a hilly area and basing the motor power on the terrain seems intuitive. Since I have plenty of power, I usually say in 7th mechanical gear and just up/down on the PAS based on terrain so basically, I am the...
