All we need is the Governerboard so we can limit our ebike with our phone, while stopped over by the Police after speeding, we adjust the speedict to 25km/h and max 250 watt ( europe )
I will build the speedict INSIDE my 18 fet controller and no cop will discover it, unless he will find this topic

yes this is very good idea !

Cool, I was hoping you would do that
Can you tell us a little bit more about these two projects?

hmmm for 10 euro? can you make it pedal for me as well please
sounds fantastic, actually....when do you think it will be available?
And please tell us about the controller too....

Is it just a rerelease of your 50amp model? Or something different?
Hyena wrote:Brilliant as it is to be able to control everything from your phone it'd also be good if you could have a hard wired button that you could program to change current modes or limit speed etc.
Hyena wrote:Another cool feature would be to a tick box type option in the software that automatically engages the limited current mode when the temperature exceeds a defined maximum. A higher range temperature sensor (or re-calibration allowing such) would be great too. Many of us running hotted up hub motors routinely run internal temperatures of 100 degrees C so it'd be nice to have an upper limit of say 120-150 degrees for those who want to push their luck.

I am having an issue with installing the Windows Drivers for Win7 x64. I understand that there is only support for x86 at this time. Please let me know when you have a driver update. At this stage of the game, I have the device integrated into my system. Notes are as follows:
We look forward to a solution.
- Attached two heat probes to external case of each controller about the midpoint of where the FETs are attached. I added additional heat shrink near the end of the probes to armor the termination, then added cable sheathing for additional protection where the wires pass through the articulated section of my full-suspension MtB. As an afterthought I realized that it would likely make more sense to insert the probes directly inside the controller, although that is more work than I can have time for this AM.
- Speed Sensor is near the rim on the rear tire. The magnet assembly is not designed to handle my thick spokes and therefore was located near the rim about an inch away. The screw does not fully engage the threads if the spoke is too thick. Ref: http://www.wheelbuilder.com/store/single-butted-spokes/
- When connecting the batteries to the controllers, I use a large 5W resistor to slow the current and reduce the spark which corrodes the contact points, shortening their lifespan, and inducing resistance. When I connected the device to the batteries the unit began to flash red/green alternately. I attached the large resistor on the opposite side between it and the controllers and waited a good 5 minutes before disconnecting and attaching the controllers directly; there was a large spark that followed, therefore I must conclude that resistor needs to be attached as
Controller-Speedict-Resistor-Batteries to avoid the spark.
- Is there a way to turn the device off? I fear extended connection may risk battery depletion unless there is a LV cutoff.
- Without the x64 Windows Driver I am unable to complete the setup, and my Android cannot connect to the device.
Best regards, KF
