    Gear sensor for universal controller?

    Did you do the continuity check to make sure red+red and black+black are connected together on the two brake sensor connectors? If so, then yes you can pick either red since they are both connected together.

    Gear sensor for universal controller?

    Yes that should work First you need to double-check there is no voltage on the brake sensor connectors. If you can't get the probes in the holes, cut two bits of (ideally non-stranded wire), strip both ends - and poke those into the holes, then you can use the multimeter to check for any...

    75100x2 13s and 16s?

    voltage dictates motor spin speed if everything else is equal, so unless you've got a method to make the controllers keep them at the same speed - with those packs, one wheel will try to run faster than the other i would expect. Not sure how that would handle - or if you'd get any increase in...

    Gear sensor for universal controller?

    yes check for continuity - black to black and red to red. If each pair the same colour are connected then you know that they are two connectors but they both connect to the same one sensor input. You wouldn't expect to see any voltage assuming it's a low sensing brake input which most seem to...

    Gear sensor for universal controller?

    i explained how to connect the three wire gear sensor in an earlier post - you need to connect the signal wire to the brake input on the controller, ground to ground and find 5v to power it from the pas sensor or other 5v output on the controller. Check out the whiteboard drawing I posted - and...

    Gear sensor for universal controller?

    you need to test them (the brake sensor connectors) with a multimeter as I suggested to see what's what.

    PAS sensor connected to wheel

    we've spent time giving you help on that in the other thread - don't ignore that and ask the same question again. What didn't you understand in the other thread? Please go back and ask there rather than start again.

    What watt?

    power is rpm x torque, torque needs amps, and rpm increases with voltage. So for the H500 it looks like it's just related to increasing battery voltage. The H550 is probably a different winding - so gets more RPM for the same voltage. That's just my assumption based on what I've read here over...

    Putting RC Lipo in series with a BMSed battery - do i need a diode?

    From what I've read on here - i think the BMS needs to be able to handle the voltage of both batteries should some sort of failure occur.

    arduino nano ebike controller board (TSDZ2+VESC)

    Ah I'm not looking to keep anything a secret, will all be open source and published on github. I'm building on top of the work of others - esp from a software point of view.

    Looking for estimate of power needed for 36V scooter

    450W is 12.5A at 36V - so that's what you need the battery to provide, very probably more for short periods. If it's struggling to put out <4A that's definitely an issue.

    arduino nano ebike controller board (TSDZ2+VESC)

    cheers, yea It's a good way to learn more about electronics for sure but no way i'm doing smd soldering on even this relatively small scale. I'm getting the boards made by jlcpcb, still amazes me (and slightly worries me!) that I can get custom pcbs made, populated, tested and delivered from...

    arduino nano ebike controller board (TSDZ2+VESC)

    I had a similar board to the above made - it worked ok-ish on the bench but was very noisy and impossible to debug properly because i'd put the arduino above most of the circuitry and so couldn't probe - rookie mistake! I'm waiting for rev.2 to be delivered that has some changes to the power...

    PAS sensor connected to wheel

    I use a method similar to this - except I wouldn't remove so much insulation and wrap so many times. I would also solder the joint after wire wrapping. Always remember to put the heatshrink over first - I dread to think the number of times I've done a load and forgotten to put heatshrink on the...

    Gear sensor for universal controller?

    exactly - as E-HP said, it's not a specific wiring diagram for your situation - you'll need to do some work to get what you want working. I am not familiar with your controller. I'm giving you the information you need to get most gear/brake sensors working with most controllers. Chances are the...

    Gear sensor for universal controller?

    nothing should be connected to battery voltage! You can see on the diagram I drew for you - the blue blobs indicate where wires are connected. So you connect the grounds all together and connect to gnd on the controller, you connect 5v from the controller to the gear sensor 5v, you connect the...

    Gear sensor for universal controller?

    just to add - if you wanted a second brake sensor - that would be connected in the same way as the first, same goes for another gear sensor.

    Gear sensor for universal controller?

    There you go, quick example connecting a 3 wire gear and two wire brake sensor to a single input on the controller

    Gear sensor for universal controller?

    I'm talking about using a prebuilt gear sensor that goes inline in the cable, like this. Assuming that works like mine (seems it's a hall sensor version, so needs power - but active is still low) - you connect the sensor 5v (red) wire to 5v supply, sensor ground (black) to ground. The signal...

    Gear sensor for universal controller?

    In two wire sensors that don't require power, they are just normally open switches that close when activated. So they will work in parallel with a single pull up/down brake input when connected in parallel. If the input is pull up, then the brake/gear inputs connect in parallel to 5v and the...

    Gear sensor for universal controller?

    If the controller has a brake sensor input then it should be compatible with a gear shift sensor as you can wire brake and gear sensors in parallel to a single input. If any of them close the circuit then the motor power is cut.

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    Does the bbs have 'walk assist' like the tsdz2, as that is effectively a binary throttle that gets you up to 6kph or whatever you set it to. Try holding 'down' on the button pad for a few seconds and see if the motor runs.

    TSDZ2 creak / click

    Crank arms are relatively easy to deform when loose i've found over the years - especially when I was a kid. Are you sure they're still square? Once deformed past a point they'll wobble a little even when tight. I've also had clicks whilst pedalling because the chainring bolts securing the...

    Arduino/ATMega based controller?

    Yea fair enough, tbh that's why i start most projects... finishing is always another matter!
