  • My second build | Turnigy G160 245kv | 10S3P Samsung 25R | VESC-X/6 | CNC-cut custom deck

    @solidgeek wrote:

    Greetings from Denmark,

    Last year I build my first electric longboard, with inspiration and information from you guys! Thanks for all the amazing builds and information avalible on this forum, its amazing :slight_smile:

    I have been riding my board for a year now, and borrowed it to my cousin a few weeks ago. He road it for a few miles, and of course fried all the electronics :smile: That gave me a new opportiúnity to create something new and hopefully better.

    So far my build will contain:

    • 1 Turnigy G160 245kv motor
    • 30 Samsung 25R 2500mAh (10S3P)
    • 1 40A 10S BMS
    • 1 Vedder Antispark Switch with 40A/50A fuse
    • 4 83mm ABEC 11 clones
    • Nunchunk with Bluetooth
    • A VESC-X or VESC 6.0 (your thoughts on this would be very appreciated)
    • Custom deck
    • 14T and 36T HTD pulleys and belt

    I designed the deck with Inkscape a few days ago, and milled it out with my X-Carve from Inventables - a most usefull machine! The deck is made of some glulam I had in stock - not sure if it is strong enough?

    It came out pretty neat, here is a picture of it with some wheels and trucks mounted!

    I plan to cut out a pocket for the batteries and all the electronics, and build a cover/lid that fits right on. All done on my X-carve of course :smiley:

    I am planning to cut out som risers for the trucks in some high quality wood, and making a motor mount out of some 5mm aluminium profiles I have lying around.

    What do you think so far, anything I could improve? Looking forward to hear your opiones :slight_smile:

  • Questions about single belt systems & recommendations

    @lastmango wrote:

    Hello,

    Been in a few discussions, and after initially wanting to try hub motors for my first build, have decided to go with a single belt system instead—I'm interested in a simple setup (translated as "I'm not a rocket scientist, so the more plug and play, the better")

    BATTERY
    I already have a Space Cell 3 Pro (10s3p) with on/off, charging, etc. I think it has an xt60 connector for the vesc.

    MOTOR / DRIVETRAIN
    6374, I've been told. I'm leaning towards the SK3, but certainly open to other options... I'm not a huge fan of the way it looks (I know that's not important to some & I get that.). Do all 63mm motors for esk8s have the same screw patterns, or do I need to match certain motors with certain mounts? I want Caliber II 50's, so I'm interested in mounts for those trucks that DO NOT require mods to the truck. How about ratios? I'm pretty confused about which ratio to buy, but I'm about 185lbs. I live in Florida, so hills are pretty much non-existent. I don't need crazy torque. Are flywheel clones a good choice, or is the consensus for the real deal—or Kegels? Oh yeah... I'm hearing 190kv as well... good?

    Thanks, gang!

    The only thing is what batteries to choose. I was planning on 10s4p.

    Hey guys.

    Thank you for even reading this, so not to waste more of your time I shall be summary and as precise as possible.

    I believe it to be the motor, since I toock it donwhill a lot, and therefore exeeding the speed I was supposed to on this set up I think. Still If I dont engage the trottel the motor produces current (right?). I mean board goes 40ish and I went 50-60 regularely. If somone has a different Idea, it would be very welcome. Also, will I allways have the risk of blowing my ride, when I go donwhilling with it ?

    Hello all i want to start off by saying i love my motors and speed controllers I purchased from torqueboards and I had a great experience with them and there remarkably fast shipping. I also am very impressed with the quality of there products so far!!!

    However upon inspecting these guys I noticed the power wire on 3 of the 5 vescs was being punctured by the backside of the hall sensor port!! im glad I noticed this befor powering up to do some testing tomorrow!! I solved this issue by cutting the shrink wrap and routing the power wires on the outside of the shrink wrap.... just thought i would share this with anyone as I foresee some possible issues here.

    Do I just have to take the whole thing apart and try to re-seat everything? Any help is appreciated!

  • Changing from 4wd to 2wd

    @ieatflys wrote:

    hello all...

    I am in the process of building a 4wd board and would like to implement the capability to switch between 4wd to 2wd.
    i understand that i will probable half to come to a full stop but i have a few specific questions to ask everyone!!

    I will run the front tied together with one master and same for the rear so all ill half to do is switch one bank of escs into some sort of coast mode.

    My questions are....

    1. Will I need to come to a full stop when switching?
    2. Are the escs and motors safe to put into a coasting mode while not putting forth any work? i know if you have a typical rc car speed controller off and coast down a hill the voltage created will blow the esc... is this the same story with the vesc?
    3. How to I actually implement this? I will be using the wii nunchuck setup so instead of using z for reverse how can I go about assigning it to put the front vescs into a coast mode of some sort?\

    Hope this is not too confusing and i want to thank everyone in advance... thank you !!!!!

  • 3 x 12S1P A123 battery build for dual hub motor Carbon fiber travel board

    @BigBoyToys wrote:

    Hey all,

    I wanted to run my latest project by you all to gather some input and ideas on a few of the build details.

    I'm going to attempt to take this board on planes with me weekly with the batteries removed and kept in my carry-on bag.

    Planned major components:
    1. Torqueboards 33" CF deck with integrated enclosure.
    2. Vesc-X (2)
    3. A123 LiFePO4 cells (36)
    4. Three small 12S BMS(s) bypassed for charging only.
    4. Torqueboard hubs or Carvon V3 hubs. Both should arrive next month so probably which ever comes first.

    My biggest concern at this point is how to navigate the battery build around the following issues.

    1. Problem: 100whr battery capacity limit on planes.
      Solution: Create 3 separate 12S1P battery packs.

    2. Problem: 0.15mm Nickel strips don't support enough current to spot weld the pack together while still using the A123 cells to their full potential.
      Solution: Soldering columns of 6 cells end to end using a PVC jig then using 1/2" wide tinned copper braid to connect pairs of 6 cells to get 3 separate 12S1P battery packs.

    3. Problem: A simple, safe and reliable battery charging method is needed.
      Solution 1: Squeeze three small 12S BMS's into the enclosure (bypassed for charging only).
      Solution 2: No BMS and just remove the batteries for balance charging on my Thunderpower TP1430 when I'm home.

    Let me know what u all think about my proposed solutions and any thoughts or concerns you have related tof my build.

    Cheers!

  • Connecting Motor With Sensor to VESC-X Questions

    @Ken wrote:

    I'm trying to connect my 5065 motors with sensors to my VESC-X's. From what I understand, if you run it sensorless, then the 3 phase wires don't matter so much as long as the motor spins the proper way. If you don't wire up the phase wires properly, along with the sensor wires, you can screw something up.

    So,

    Does anybody know if the colored wires from these motors are standard as far as phasing and hall effect sensors go? Also, the Enertion VESC-X has the three phase wires that are unlabeled, AND they have a 6 pin connector for the sensored motors, but it seems that most of our motors have 5 pins. The schematic from the motor is labeled: Pos (red wire), U (yellow wire), V (white wire), W (blue wire) and Neg (white wire). The pins on the VESC-X are labeled 5V, H1, H2, H3, T and GND. From the little bit of research I've found, U,V,W are the European equivalent of H1,H2,H3. Can anybody confirm that?

  • Adding copper wire in the Motor-Vesc connection for additional contact?

    @jm.riviere wrote:

    Hi there,

    I've been experiencing some problems with my build and my theory is that the problem lies in the connection between Motor and Vesc (the 3 pins): the female part of the Vesc is too large, reducing the contact surface (I found some "burning" marks on the male connectors, which seems to verifiy this hypothesis, I think?)

    Anyway, my idea is to add some copper wires to tighten the connection without losing conductivity/contact surface. Can anyone tell me if that's fine for both Vesc and Motor? Here's what I mean:

    I'd add some heat shrinking tubes around it.

    Thanks in advance!

  • How do you charge your longboard?

    @Dougieman1001 wrote:

    Hello,
    I'm just curious how people charge their longboards. For examples: Do you charge them by taking the battery/ies out and charging them externally or charging them through a plug on your board like any production electric longboard out there? If you do the later do you think you could enlighten me how you do it as I am curious and it will also make charging much easier.

  • Communication with VESC through UART?

    @Mike_Lemon wrote:

    Hello,

    I am developing a new Esk8 system that will have many useful features both with the remote and and on board PCB and I'd like to use the UART communication to control the motors so I just wanted to ask:

    1) what is the format of the protocol for example: my one goes like that ATTN then addres < Data>
    so if I would write it it'd look something like that to set motor speed to 100 ATTNMSpeed<100>
    2) I see there is an arduino library for that but I don't know the values of the current range
    3) Do I have to set motor current to 0 before applying brake current or it does that automatically?

    Thanks for your time.

    Hi,
    I'm using a build with a VESC and a standard 2.4 Ghz transmitter with receiver. The connection cable between VESC and Receiver (3pin servo cable), however, sometimes looses connection on the receiver side - I guess due to vibrations. On the receiver side it's just hold in place via a plug. This is quite dangerous at high speed. Did someone have the same problem? How did you solve it? Directly soldering to the pins of the receiver?

  • Limiting acceleration and acceleration profiles

    @Peter1 wrote:

    Hello everyone!

    We are building an electric longboard with a team of university students. Our goal is to make an electric longboard with different driving modes. Because of this, we are working with an Arduino which communicates with the VESC via UART.

    One of the modes that we are using now is just straightforward by using an RC controller. We were also thinking about a way to limit the acceleration of the board (maybe in a different mode, so the user has the option to chose this or not). Furthermore, it is also important to limit the jerk (derivative of the acceleration).

    We were thinking of an algorithm for applying this, but it's deffinitely not as easy as it looks. Due to this, I started thinking that we are probably not the first ones to think about this idea. So my question is: is there already a good control mode in BLDC-tool that limits the acceleration (and variation of the acceleration to drive smoothly)?

    Kind regards,
    Peter

  • Semi DIY / Benchwheel Penny Board Base / Adding modular parts

    @rod_r wrote:

    While searching for my ideal commuter board, I got a Benchwheel Penny Board on closeout, and setting aside quality, it actually has pretty close specs to what I'm after. So I am looking at transforming it into more of a DIY, so that I can consistently replace parts as they wear out. So far, I have transferred the enclosure onto a new deck, and swapped out the trucks, [ apart from the rear hanger ].

    So, the basic penny board spec is:
    10s1p battery of Samsung 18650 cells.
    n5065 170kv / 1000w sensorless single motor
    48 / 16 pulley using HTD3 225 belt

    I'm hoping to pretty much keep the enclosure and remote as is, and would initially concentrate on the motor / drivetrain. Where I'm up to so far is;

    1. Benchwheel offer replacement motors, but I'm hoping to be able to source good quality replacement motors elsewhere, but so far I have not been able to locate an alternative source. DIY only have a 190kv 5055 which I've been advised is too light. If I can't locate an alternative source, I'm not sure I want to plow any money into this project.

    2. Wheels. I'd like to be able to use Abec or similar wheels, but after reading through this board, there is no current product that works on the benchwheel, [ it uses HTD3 ] so to use alternative wheels, it looks like the whole drivetrain would need replacing. DIY and a few others offer good kits, but again, without a good motor supplier, it may be a waste of money.

    This is my first thread, so I'll try to post a pic of the board in it's current form

  • Confirming vesc setting for 6s

    I am running a 6374 230kv motor, 2x 6s 5000mah batteries in parallel for a total of 6s 10000mah. I just got a vesc and wanted some opinions on vesc setup. Here is what I got so far.

    Motor max: 80a
    Motor min(regen): -30a
    Batt max: 50a
    Battery min(regen): -6a

    Are these good settings? I just don't want to fry anything.
