Re: TSDZ2 48v 2020 new firmware

I have a different view, that we are unlocking the ThongSheng motor, changing the different products models of different motor power and battery voltage, so we are damaging ThongSheng business model. Just the same we did when unlocking the EBike displays KT-LCD3, SW102, 850C and 860C. And we are al...

Re: TSDZ2 48v 2020 new firmware

Why I would care about Segger but not about Tongsheng? Because you're paying tongsheng for hardware, giving them revenue for their product whereas you're buying knock off segger and using their software, IP... to program the tongsheng. It's quite different. Hypothesise that someone takes your sourc...

I received the new DC-DC and is so tiny that I wounder if I could quick adapt the wireless remote case to include this DC-DC, in exchange for the CR2032 battery. Also 2 mosfets must be added and more space for the motor controller UART cable... The thing is I wanted this DC-DC to make the smallest p...

Re: TSDZ2 EBike wireless standard (like Specialized Turbo Levo) - OpenSource

Just a totally different thought, but do you realise that you now have the basis for an SRAM etap style electronic gear changing system? As I see it, all that is needed is some way of pulling and releasing the gear derailleur by means of a stepper motor attached to the cable. I have seen such a sys...

Yes it't good law. But it takes a long time before it works in practice. And I think Chinese don't care about it. Europe can obviously affect that to not buy products from China. Part of the law says we will have a signal when buying the product, like the previous law that added obligation for ener...

I'm not comparing the wrong one... The little MESC board in that pic can push many kW.... so I am comparing it to the 1.5kW KT case. If I made a 250W board, it would be <half the size again. Your board would need to have advantages over the others other way why bothering?, so, putting a more powerf...

I don't have to skills to repair but if I find wiring diagram I can go to local electronic shop and ask if they want to fix it. I think the display can be water proof again when it is put back together with glue. Both SW102 and 860C displays were made to not be repaired as they have no screws at al...

Is there any wiring diagram for the 860C display. This suddenly ceased operations. Maybe there was a short circuit in TSDZ2. 860C_Board.JPG 860C_Board1.JPG My 860C also stopped to work suddenly, while the bicycle was on the garage. And it is expensive and I do not know how to repair it, also there ...

Of all the things you could possibly want to keep hold of, the enormous ugly metal box is surprising. I will watch this with interest regardless, and if the results seem particularly good...

This is fantastic news. You're well on your way to having probably the best FOC controller going. With this in mind, do you have any interest in me forking the MESC and replacing the stm32 with this mcu? It wouldn't take me much effort (few evenings to do the hardware) and then you could have this ...
