Re: TSDZ2 open source firmware only for KT-LCD3 (v0.19.0 / v.0.20.0beta1)

0.20, makes every ride an early christmas. Can't wait to see what sw102 and 850c when its a bit more mature around the curve! I have seen the awesome torque calibration work that has been done, though my torquesensor is not health personified, I'm holding off a bit. Thanks devs and testers again!!!

Re: opensource 3d printable electronic shifting?

Nice find BalorNG! Came here to post something I stumbled upon lurking and raking the net about odrive for a corexy machine. Anyho, found these type of Linear Actuator s, which very well could be the droids we are looking for as they are conveniently packaged. Never mind the fancy remote & etc in th...

So, using PAS mode it would be as if I put in a lot of wattage or how does that work?

But the emtb is so nice!!!
I never used that mode, I don't know.
Hm, Ok.
What is 'I_max' ?

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

The torque sensor seems dead. I jumps a bit 0-5 adc value. Off to buy a replacement, I suppose. Man those cable are fragile, I treated the torque sensor as nitroglycerine and it loosened very easily. :confused: Yes, the hardware calibration of torque sensor is very delicate.

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

I have installed a temp sensor. However, the install was horrible, as the first screw to the motor controller loosened almost to easy, but second one. Jeez.. I was very careful for ten minutes, and then the screw was done for. So I put the torque cable aside and pushed the cables through so I could ...

Hm, that's something like $0.025 á km and maybe 5h? of fixing, worst case?

Question:

Is the lights supposed to stay on when the battery is connected, (motor off)?
My backlight is always on, I had the front connected for a while, however the tsdz2 could not sustain it.

Axle diameter? DT SWISS Hub rear 350 Big Ride

Hi!

Need to make a 12 mm axle for a rear 197mm DT SWISS Hub 350 Big Ride hub, (axle with nuts)

What diameter and length (smooth 197mm?) should the axle be?
12mm precisely or should I make it 12,1mm etc?

Thanks in advance!

Any news on the "Making the SF102 update using the BLE factory bootloader (no need to open the case) #35"-front?

Got a SW102 ready to flash, got 0.20.0 in the tsdz2, holding of a bit till its supported. I'm a eager guinea pig though.

So, getting open source software on a device like this... indeed, the possibilities..

One nice thing could be "the front end for (a) bluetooth open source shifting (BOSS)".
Sure there is xshifter, but $400 is a bit steep, at least to me.
