HOW TO BUILD A DIY ELECTRIC ⚡ SKATEBOARD TUTORIAL – VESC & RC REMOTE CONFIGURATION – PART 3

HOW TO BUILD A DIY ELECTRIC ⚡  SKATEBOARD TUTORIAL – VESC & RC REMOTE CONFIGURATION – PART 3


What’s up eskaters Neil with Big
Kids and on this channel we talk about DIY tips, vendors, and the electric
skateboard community. If you’re new here please consider subscribing and hitting
that notification button to keep updated on videos like this one. Also check out
the show notes below for any information and links I leave in the description.
This video is part three of my DIY electric skateboard build where I
configure the VSC and the RC remote but before I do I’d
like to mention the giveaway sponsor of this episode build get boards for the
sealed motors two battery packs bill give boards has quality parts at a fair
price for your DIY project if you haven’t already check out the online
store and for those of that entered the raffle giveaway from the last video I’ll
be announcing two winners at the end of this video so feel free to skip to the
end for the rest of you that want to see how to configure the V ESC and the RC
remote let’s go the better electronic speed controller or the ESC is a speed
controller that revolutionized the Eastgate seen before the V ESC the DIY
community rely on speed controllers that were used in RC vehicles the VSC
developed by Benjamin Vetter is an open-source controller made specifically
for Electric skateboards what makes the V ESC an awesome option is that you
could configure your settings via software called BLDC tool that better
developed and because the B ESC is an open-source project they’re actually
improved versions of the BLDC tool that were created by the DIY community for
this project we’re going to need the BES see the BLDC tool an RC remote and
receiver and a servo connector power up your board because the V ESC will need
current in order to be configured use a mini USB to plug into your B
and then connect it to your Mac or Windows computer you’ll then want to
download the BLDC tool from the links below so after you’re all connected
you’re gonna want to open up BLDC tool I have BLDC tool and the V ESC firmware on
this is 2.18 which is the correct version for my b/c hardware my hardware
is 4.12 they do have a vest 6 out as well but you’re gonna want to check your
ve SC to see what hardware version it is then you’ll want to connect to one of
the comforts if you look up here in the upper right hand corner you’ll see the
different ports that are there in my case there’s just one sometimes you may
see more than one up here and you don’t have to worry
you could choose either one and you know through trial and error find out which
one is yours and then just choose connect if you look at the bottom that
will now show my status as connected once we’re connected we could now read
the default configuration of what the manufacturer had sent this ves C
configured F so here we go these are the default configurations and the two
things are going to change on this motor tab is the motor is the current limits
and the voltage limits everything else we’re going to keep the same so let’s
start out with the motor max the motor max is the maximum amount of current the
V ESC is supplying to the motor a value that is too high will overheat the motor
if it’s over the max rated watts of the motor as the motor can’t withstand you
know that amount of current so to find the highest amp setting for your motor
we’ll use this equation amps equals watts divided by volts so take your
motors max wattage and divide by your battery’s voltage in this case we’re
using the 63 70 full quarter from torque boards which has a max
wattage of 3000 150 watts our battery voltage you know we can find out by
taking the number of cells which is 10 and multiplying that by the nominal
voltage of each shell which is 3.7 volts so 3000 150 watts divided by 10 s times
3 point 7 equals 85 0.14 amps so now that I know the max amps that my motor
can potentially handle I want to set it to a value below 85 amps just to be on
the safe side so I’m gonna put it at 60 amps which i think is a reasonable
setting for my 63 seven border so now we’re going to move to the motor min
regen motor min is the amperage that would be generated and applied for
breaking I weigh about 150 pounds so you know I’m gonna change the default
setting the lower the value when ignoring the negative sign will give you
less braking pressure while a higher value will give you more braking power
I’ll set this to negative 45 I suggest you know testing different
values until you’re really comfortable with how it works for you so now we’re
going to move on to the battery max this value is the max number of amps that the
ve C will allow from the battery to the load so the load meaning your motor what
I usually do to find the max capability of my battery is to use this formula amp
hours times the C rating equals amps I multiply the a power rating by the C
rating of the battery pack and then divide by the number of motors in my
case I have a five thousand milliamp battery or a 5 amp hour battery and I
multiply that by 30 C and that equals out to 150 amps total continuous current
so now I divide that number by the number of motors I have and then you
have the max amp so you can safely discharge
so now we know the battery’s capabilities in regards to its max
continuous current 150 amps is more than enough to support the load in this case
because the B ESC has a 50 amp continuous current limit and up to 240
and bursts to be safe I’ll set my max battery value to about 15 amps so now
we’re going to move on to the battery and regen this value affects your
braking at higher speeds as well as regenerative braking so when braking the
motor regenerates energy that is sent to the BSC to be redistributed to the
battery to get this value you always want to be safe to set it to charge at
to C of the capacity in my case I have a fine a power battery times 2 C equals 10
amps so this doesn’t necessarily mean you’ll always be charging at 10 amps so
if this is not enough braking power for you you can always set it a little bit
higher but I’m just to be conservative I’m going to put it at 10 amps absolute
max will leave this alone and what you’re going to want to do next is to
click right configuration this will set those values to the felices right the
configuration to the V ESC and these will be your new values make sure on the
bottom right hand corner it says that it has written and we’re gonna move on but
let’s move over here to the voltage limits the minimum input voltage we
could leave at 8 if you want to set it to be lower that’s fine too my buddy at
I am deluxe he sets his at 6 because apparently it helps when testing but it
really doesn’t have a huge effect when you lower it this little 6 8 should be
fine the maximum input voltage we could leave that alone
and then the battery cutoff start is this is a pretty important value so like
RC batteries have a voltage range of 4.2 volts at a full voltage and then 3.0
volts are completely empty the battery cutoff start is the voltage I want to
start slowing down the battery as kind of like a basically like warning that
I’m reaching the cutoff voltage for your battery health you do not want to drain
the battery down to 3.0 or 0 what is recommended for a battery health is that
you do not go below 3.5 3.5 volts for lipo batteries I know for lithium-ion
batteries you can actually go a lot lower than that but four lipos three
point five volts going anywhere below that is it recommended so I usually set
the battery cutoff to about three point six to kind of start slowing down and
then battery cutoff end is when the V ESC reaches the input value it will stop
the board as as if it’s like out of power in this case I want to set the
value to three point five like I mentioned I don’t want to go below three
point five you can if you want to increase your range but going below that
too often will shorten the lifespan of your batteries so now that we have that
let’s write the configuration again so next up we’re going to do a motor
detection and the motor detection is done within the BLDC tab so click over
to that the V ESC will optimize its performance based on your specific motor
settings in order to do this we’ll want to go to the bottom left hand of the
screen and then click start detection you’ll then see the motor spin and
you’ll also hear kind of a strange sound once you’ve completed start detection
you’ll notice some new values under the detection results right here you’ll want
to move those values up to where it says sensorless communication mode right here
under that there are three fields the integrator limit the internal limit min
ERP M and the B EMF coupling what we’ll want to do is transfer the motor
detection values to the corresponding fields under the sensor list
communication when inputting the values it’s best to round up to the nearest
whole number so in this case integrator limit is 128 point nine four so we’ll
just bring this up to 130 in the ERP M limit don’t worry about that leave that
the same the B EMF coupling is set to 756 so we’ll just set that to 760 then
you’re gonna want to write configuration and make sure in the status bar in the
lower right hand corner it shows that you’ve written and we’re good to go here
so let’s step away from BLDC tool for a second and connect the receiver to the
BES C as well as the RC remote and bind these together this is the
trigger style type of RC remote that I bought from DIY electric I’ll leave a
link below and there are a lot of different types so your process might be
a little bit different this but this is kind of gonna be kind of the basic
process so what we want to do here and I’ve kind of gotten a head start is you
want to have a servo plug that you could also purchase pretty much from any DIY
electric skateboard vendor and we’re going to be plugging it in to channel
two you want to make sure that the neutral side is on the outside of
channel two and the neutral side is always the black lead so let’s do that now that that’s connected we’re gonna
want to connect this to the V ESC now just for example reason I’m going to
show you this VES see if we get up close you could see this is right here there’s
these three pins there’s these three pins right here and
that’s where you’re gonna want to plug in the RCR the the receiver servo so
that’s what we’re gonna do you’re also going to want to make sure that the
neutral line is facing out and now that we’ve got that connected you’ll also
need a binding loop key this usually comes with your RC remote so after
you’ve gotten this loop key you’re going to want to put that into channel 4
there’s no particular way to plug this in so either way whatever way fits so if
you see here that’s what it looks like now that we have everything in place you
take your remote and this could be different for every different remote but
I’ll be doing this for example and you’re gonna want to hold down the pair
button and turn it on you’ll see a red flashing light and then you’re gonna
want to turn on your electric skateboard and you’ll see a flashing light on the
receiver what you’re gonna want to do is wait until the red light on the RC
remote is solid and then you’re gonna want to turn it off then turn this off
and you’re gonna want to pull the binding plug out and I’ll turn this back
on and check it if it paired now let’s get back to BLDC tool so let’s reconnect
to BLDC tool again I’ve plugged in my USB into the VSC and also into my
computer you’re going to want to choose the con port in this case again just the
one for me connect and then check the lower right hand corner in the status
bar to make sure you’re connected we’re gonna configure the RC remote so that
it’s optimized and the best way to do that is you’re going to want to click on
app configuration tab and then read the configuration that current that we
currently have right now it’s in ppm ppm is basically any RC 2.4 gigahertz
remote so we’re going to just keep it 2 ppm you could also use ppm and you art
or you art nunchuck those are all like like different things like the Bluetooth
app that you could use you could use the Nintendo nunchuck which was pretty
popular at one time but in our case in this
we’re going to use the RC remote so that’s going to be ppm I’m gonna choose
the ppm tab over here to get to the configuration and before we move forward
I suggest that we disable this just so that it’s not going to be connected to
the motor at the moment and you know just kind of keep noise down for now
and we’re gonna write configuration so now that two values that we’re going to
be changing is the minimum and the maximum pulse width and in order to get
those values right now we have them set to one and two which are just the
default we’re gonna have to test our RC demote and so what we want to do here is
click the Display button and this bar is basically you’re gonna see it go up and
down when you hit the throttle on your remote so in this case I’m hitting down
the throttle and it’s going to 89% so you want this to go up to 100% and then
when I hit the brake it should go down to zero which it is right here if you
look to the right of that there is a value which will be putting in the
minimum and maximum pulse rate all right so let’s hit the throttle and the value
that we’re seeing there it’s kind of a weird finicky value but it looks like
1.89 so for the maximum pulse width value instead of two we’re gonna change
that to one point eight nine nine yeah and then
we’re gonna break and that takes us down to the pulse-width of 0.99 so we’ll
change that and then when you’re done with that you’re gonna want to write
configuration so that it writes it to the V ESC and now this should go to one
hundred and this will go down to zero perfect so we’re done configuring the RC
remote and what we want to do is get out on the road but before we do you want to
click on current no reverse with brake click that and write configuration and
now that that’s ready to go you have connection to the motor from the RC
remote and let’s disconnect from the B ESC and get out of here
all right so hope you found that a tutorial helpful please keep in mind
that you should use this video just as a reference if you want to learn more
about the V ESC go to the electric skateboard builders forum for more
in-depth Theory troubleshooting and ways to optimize your performance and if you
missed anything from part one or two of my videos those videos are up on my

Great video Neil, you need to do a part 3(A), setting up VESC with the new VESC Tool software. Its much easier to setup vesc, the new software practically sets up everything for you. If you need help, let me know, just PM me, im just paying it forward. Great Job. 👍👍

I have a quick question. How do I build this setup with 2 motor? Do I need 2 VESCs? If yes, do I connect the 2 VESCs to 1 receiver? Also how do I have to configure the VESCs with the software? Do I configure them individually and put in same numbers?
Great tutorial. Keep it up man. Greetings from Germany.

Hey, thanks for the video, I am from RECIFE in Brazil South America and I correctly own 2 boosted boards v2s dual pluses, and thinking of getting the Kingsong KS-16S / 840Wh, but hey your videos are the best and everybody loves your videos down here in Brazil…

Hey Neil, one question, how low can I discharge a 5000mah Lipo before I have to charge it.
PS: You make very good content.

VESC tool has better remote-specific features:
– better remote setup wizard
– throttle and brake curve adjustment
http://vesc-project.com/vesc_tool

Fam, your vids are fantastic! By far my fav new creator! Do you plan on ever doing some reviews on other DIYers, or brand name boards? It would be pretty cool to bring content on DIYer's more so than the big 5 out right now, e.g., Mellow, Boosted, Evolve, Enertion, Metro. What's your opinion on Carvon. I see the CARVON V4 TORQUEDRIVE are on sale. It seems to fit in my wheel house on what I need. Any insight on these?

I need to send you an email on my build I am planning out. Would of sent an email a while ago, but my baby girl was introduced to the world and sleep and time is not on my side. I do have a question about a few things. I am thinking of going either dual 6374 or dual 6355. That will then put into motion which trucks I am going to purchase , gears, pulley etc. With the hills in my area, I am sure dual 6355 would be more than enough. Configure my mass at 200lbs with inclines of 8-15% grade hills has me worried. Not trying to stress out my motors. I guess I just need reassurance that the 6355 would be good to go for what I would need. Also, I am planning 10s4p battery or 12s4p. What do you think?

Hi Neil . How much did it cost to make your own board and is it really hard to make one ? I am asking theese questions becasuse
I am 13 and i dont have any information so how much can it cost ? Thank you , greetings from Turkey .

Hello Big Kids, would you be able to make a tutorial on how to add a battery percentage indicator to youre board. Like how to connect it to the battery or the power switch. And great video. thanks

Hey Neil, a fantastic Vesc tutorial very very detailed and extremely well done. It’s funny how technicians used to work with tools and they’re working on windows doing adjustments in little boxes with numbers lol … how times have changed. Congratulations on the final tutorial on the DYI EBoard. This is a wonderful opportunity for someone to make their own EBoard and with your detailed steps they can’t go wrong. What a great contribution you’re making to the Esk8 builders forums and builders community congratulations Neil, lovely to see your daughter she is gorgeous you should be very proud, brings back memories of me and my daughter Georgia she is now 27 they grow so quick … congratulations again Neil on the work you put into these videos and keep up the great tutorials ))) cheers Andrew )(

Hey bro, great quality as always : )
I just finished to build my new electric skateboard: https://www.youtube.com/watch?v=3Z_aUJ–kkQ

Hey Neil! Great video as always! I have finally gotten around to making my own board, and I am trying to figure out the best VESC settings for my board. I have large 100mm wheels, a single 6355 motor for now, and a 12s2p battery pack from diyelectricskateboard.com. Is there any way you could help me figure it out? Right now, my acceleration is very slow and it might just be because of my big wheels but I am not sure.

Yoo whats good man!? Question, have you always used the BLDC configurations for your VESC from TB? I've read a lot about people who experienced troubles with frying their VESC when using them under the FOC configurations instead of BLDC for the additional benefits (less noise, efficient, etc). I'm trying to figure out if it's worth the risk since TB doesn't offer a warranty on the original price for their VESCs.

Had a question hopefully you can help me out looking to build my very first electric skateboard. Thinking on a Sector 9 bintang deck but I'm not sure if the DIY electric skateboard 12s4p enclosure V1 will fit. Any thoughts.

Neil! Where are you from in Chicago? I spotted your IL plates in your videos? I noticed on Fb that we have a mutual connection, Dave Dimaano. I grew up in Glendale Heights, lived most recently in Oak Park. Moved to SoCal about a year ago. Hit me up for a skate if you’re ever in town, pare. Love your videos!

Hi, this is really awesome. Just a few questions.
How much would this cost?
Have fast does this board go?
How many miles can it go before a recharge?

Thanks

AMAZING stuff here! Thanks to your 3 part series in a matter of 3 weeks I went from knowing nothing about electric skateboards to purchasing, building, and configuring my own. Keep it up!

Quick question man, have you set up Carvon V4 motors? Where do you think I could get some initial settings so I dont destroy my built? And what VESC would you recommend? The upcoming ENERTION FOCBOX with 2 VESCs looks GOOD!

Neil, You're doing a really great job here. It is so hard to find a good step-by-step guide for DIY Eboards. You nailed it! Thanks a lot!

Hello Big kids, I 'm currently building a dual motor electric skateboard. I bought Turnigy SK8-ESC V4.12 for speed controller and was wondering if it was possible to connect 2 of them (with a connector) so you can control both at the same time.
Ty

Hey Neil – Great tutorials… Here is my build: https://photos.app.goo.gl/KvlOTOfdesGViCfe2
I used most of what you recommended. I got a Rimable board cheap on Amazon (Its Ok. It has those raised sides, which I don't like) – Overall, A solid 42" board($29 on sale). I used a parts container from Home Depot for the electronics(cut off handle. Has plastic hinges – So… I don't recommend). I went with the 97mm flywheel cloans, 36t and 14t pulleys, 6374 motor, DIYE mount from Amazon, Caliber II trucks, Zippy 5S 5000 LiPo's from Hobby King, VESC, Motor, pulleys from https://diyelectricskateboard.com/. Anti – Spark On/Off switch from ebay, and battery percentage indicator from Amazon.

Thanks, Keep up the videos, They're great!

yo, how do you make the second wheel move with the motor? the first wheel is attached directly to the motor, but what about the second?

Thanks Neil, you’re a great teacher. How much total is this build, I have RC parts but not sure if I can afford all this?

I've problem when I try to make a motor detection it failed on the debug console it say : "Status : Bad Detection Result Received" . I tried to change battery cutoff start and end (to lower them) but didn't change anything …

I've a Torque 6355 Motor, 2x6S battery and this VESC : https://hobbyking.com/fr_fr/turnigy-sk8-esc-v4-12-for-electric-skateboard-conversion-w-bec.html

I also try to update firmware but that didn't work also …

I'm pretty depressed ….

My software is not exactly the same (think is more recent that your one). Do'n't know if it change somethng .

Does it matter what VESC and motor combo you use? What about battery voltage and current output? If you noticed your batteries are draining too fast can you just add more batteries into parallel?

My computer won't recognize the VESC. I have bought a new data mini usb cable and no luck, i have installed the stm32 driver and no luck. any help or tips would be appreciated. thanks!

You set the values your talking about @9:55 to 36 & 35v instead of 3.6 & 3.5 like you stated you wanted. Huge difference there.

HI! if I'm trying to do a dual motor build will I need 2 vesc's? i tried shopping for one already but there doesnt seem to be much regulation.. which one should I choose?? thanks in advance!

Will be cool to have a way to change the regen value on the way, with the Iphone or something through bluetooth, wifi or usb, that way you could charge the batteries while you are going down a big hill (setting the regen to more torque), or charging the batteries while riding with your legs ( setting the regen to less torque).

hey
following you i built my own board, but there is a problem that i have used a simple battery indicator from bangood and used a 18650 battery pack at 10s 2p configuration the problem is when my vesc cuts off the battery indicator is still showing 20%
so i wanted to know that is that normal or is it only in my case

I already own a Boosted Stealth, and ordered a Lacroix… I don't think I can build a board better than the pros like you, though I am interested in troubleshooting problems under the hood w/ the VESC software. Since the VESC platform is used to configure and monitor the settings of electric motors and remotes, will I be able to access such data from the commercial boards I purchased? I have to go back over your video and look at how you connected the computer to the VESC Controller via USB… I guess the question should be, do most commercial electric skateboards have a VESC controller, or are the VESC setting proprietary (inaccessible and/or behind a firewall)?
I enjoyed all three videos… How did you learn all this? Pretty amazing that you figured out all those settings in the VESC app… you must have a few friends you can concur with, less you might fry some parts or even cause an explosion.

With 200 dollars can i build a complete electric longboard?, i alredy have the deck and the trucks that come with the deck.

What's top speed and distance? How about uphill with your body weight. Do you have any problems to go up hill. And what speed are you going uphill. Thanks.

How are we supposed to know if it’s actually better than boosted board if you don’t even have a text ride video? Haha

Someone who knows about electricity: what happens to the current when i stop accelerating whilst going downhill? the battery at this point stopped providing energy, so, does the motor begin to act like a generator due to other forces acting on it?, absorbing kinetic energy and generating so its electricity fluxing outwards the motor (opposite direction of the energy provided by the batteries and it's control system). Can this damage the system that controls the flux of the batteries' energy? Or is there anything that prevents this to happen?

Great series, I'm looking to make my own soon.

Question: Have you looked into what can be done to weather-proof this board? And protect the belt from debris?

What are the step for charging the battery when it's empty? Do you plug it in the serie connector and it works?

First 2 videos: easy for a DIY person like myself…
Third video: electro mechanical engineering degree needed.

Hey man i have a big 10s 36v battery do you think its enough to go 40 kmph/25mph and can i skip the hole merging battery thing
