    8mm connector -- for xiaomi m365 -- where to find?

    That image does not load for me. The good news is that they are now available on both aliexpress and ebay, even though the machining looks a bit different to the cable on my charger (mine has very smooth transition between inner and outer shell at the tip, while the ali ones have a visible...

    8mm connector -- for xiaomi m365 -- where to find?

    Been asking myself the same, must be that the M365 factory also makes their own connectors? A bit strange decision?

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Hello, I am looking at getting one of these in the near future. How accurate is the torque sensor, or rather, how accurate is the human power reading generated from it? As far as the 16kB/32kB issue is concerned, is it possible to replace the stm8 onboard? From what I've seen around the web...

    Help me disassemble this aikema motor

    7% is not steep at all, I can do 10-15 km/h up such a hill on leg power alone. One of the hills around here that I climb is 26% of the trip in the 10-15% grade, 7% in 16+% grade and is representative of the hill roads around here...

    Help me disassemble this aikema motor

    I'm not sure if I understand that set-up... I've looked into ordering and shipping is indeed hella expensive, even the basic KT sinewave controllers (which I'd like for the FOSS firmware upgrade) that are listed for ~$25 add $20(bmsbatery)-$50(pswpower) when checkout is attempted. What is going...

    Help me disassemble this aikema motor

    I saw one of those crude solutions (however the target motor was different). My problem with this is that I simply have nothing with which to make a 35mm hole into metal. Thus my option is some hard wood with perhaps a metal plate added to the side to reinforce it (a plate that only has a hole...

    Help me disassemble this aikema motor

    Thanks for the response I have drilled into a block of wood and mounted screws in it, but all I achieved was the wood cracking. I'll need a stronger piece of wood. Any idea of the required force to unscrew it? Max motor force + max pedal force applied in reverse? How much is this? The...

    Help me disassemble this aikema motor

    Greetings all, sadly this motor left its last breath near the top of a 300m hill (grade ~15) Symptoms (bicycle flipped upside down = almost no load): - when starting, it jerks back & forth. - when it picks up speed, it produces much more noise than it used to. Any ideas how to open it up...

    Cheap FOCer (VESC 4.12 based design)

    It wont matter for the PCB, but the problem will be inside the wire, as the solder will creep up under the insulation and create a mechanically weak point. See article. The classic pcb is only 1.6mm thick, it is not enough to mechanically secure the wire against this.

    Cheap FOCer (VESC 4.12 based design)

    No, I have not been looking for them, yet. Which ones? From what I see on your github photos, you are using Mini-PV (aka Dupont) for this project. There is an article here by a person discussing some connector systems and crimping tools: http://tech.mattmillman.com/info/crimpconnectors It...

    Cheap FOCer (VESC 4.12 based design)

    $3.3 * 6 = $20 $1.19 * 6 = $7.2 They could be better, but there is only so much upgrading that can be done before it becomes Not-So-Cheap-Focer. Is there an assesment at how much more efficiency we'd get from those $13? 1. Have you considered going for 12 mosfets from the start? 10+ and we...

    kWeld - "Next level" DIY battery spot welder

    Heh. When I see "DIY" on something, I immidiately expect Velleman-style DIY where you are given a bag (box) of parts and wished good luck. Anyway, I did look for bus bars on Arrow, but the search comes up with either circuit breaker mounts or 1m long rods for >25 eur like...

    kWeld - "Next level" DIY battery spot welder

    Being the cheapskate that I am, I am now wondering why you people (kWeld, malectrics,..) use bus bars? They are an unnecessary cost when you can just take a thick stranded cable, peel 10 cm off of it and distribute the strands evenly to each MOSFET. This also gets rid of connector crimping and...
