Hello Danny

That is an impressive application! Really very cool.
With regards to the 14-AWG wires, I shall remain optimistic unless proven otherwise; it is the best that we can hope for.

Thank you for your kind support
Best, KF

[Bazaki]

100v 100a no problems with 14awg over that short distance of wire for a few seconds, the speedict survived it all

[Green Machine]

Thanks for the Temp Sensors danny...just got them...speedy shipping!

This is really awesome company.

Hong Kong direct to the consumers.

Everything works great with Speedict and Danny

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

let see if we can squeeze little bit time to complete the governor coding before speed controller project
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?

Governor board is the external module for Speedict eBike, featuring :

1. speed regulate - e.g. you set 25km as max speed, so when you apply full throttle we control your max speed to 25km, when apply half throttle speed will be ~ 12km
2. current regulate / current throttle - e.g. you set max current output to 30A, so when you apply full throttle we delivery only 30A max, when apply half throttle, current delivery only 15A so on ...
3. low voltage cut off
4. cruise control

all these setting can be done via android, so you can set up different profile for different conditions

by the way, we estimate the price for existing ebike users around eur 10 ... is it ok ?

[jonathanm]

... is it ok ?

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....

oh yes it is PAS as well ... when ? we did 95% but we are very busy on speed controller project in higher priority therefore we put it aside ... let me discuss with our team member next week to see if we can launch it first

What are the specifications for the controller you are developing?

Is it just a rerelease of your 50amp model? Or something different?

featuring bluetooth, governor, dynamic regenerative and pas ... will release more information here later ...

Once you have this add on govenor board it'll really make the speedict stand out Danny

It'd be great if you could make a "performance" model that can 100v, surely it wouldn't require too many changes to the existing board for future models ?

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.

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.

Any more news on cheap little stand alone screens to use ?

If you really want to rock our world, add in a chip for monitoring and displaying individual cell voltages. Offer this functionality and I'll happily cruise around with a 7" android tablet as a dashboard on my handlebars

don't want cop can trace the wire to the system, everything go wireless right ?

yes sire, everything can be done by software !

we have sourced 4" china cheap android PMP, and we are working on to activate its bluetooth, the cost around eur25 !

we have plan to do BSM and monitor every single cell !

[Webbo]

Deff needs to measure at least 100v. But very nice

someone used to measure 100v already !

[number1cruncher]

This sounds awesome! A controller that monitors each cell would be very useful and would cut out the need for a separate BMS during discharge. I guess I'll be getting an Android phone soon!

BSM is on our project list

[Bazaki]

People, the speedict does measure 100v now.

bazaki, could you upload your crazy log and gps map here ?

Greetings.

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:

• 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.

We look forward to a solution.
Best regards, KF

1. yes the magnet is hard to fit in to 2.3 mm spoke, we are sourcing bigger magnet but still no luck !
2. for high voltage yes you can add resistor to it.
3. the only way to turn off the speedict ebike, you can either disconnect battery or add a switch on it, as we want to make speedict's size as small as possible therefore we didn't add power switch on it.
4. we have no plan to provide x64 bit driver as this moment. can you tell me why you cannot connect android ?

if there is any problem please send me back for replacement

cheers,

danny

Here's an option if XP mode doesn't work - install Virtualbox or VMware player and install 32 bit XP in it......

Yeah, I am going to try that in a bit

By hook or by crook, KF

[shinyballs]

Besides recording and displaying temperatures, what other temp related functions are there? Is there a min/max temperature setting, i.e. when reached can trigger an alarm and/or disconnect power? This is a good alternative if it can handle at least 120v.
