Louis’s First Build? Nothing Special, Move Along | [Clickbait]

Ha! Hello clickbaited esk8 nerds.
Right! So it’s time I share my first ever build with everyone! it’s been a bumpy ride. Hell, it was full of potholes tbh but I didn’t burn the house down!
Future reference circa late 2021 @Halbj613

This build didn’t turn out to be what I expected, I’m a bit disappointed. You’ll see.

2019

So what brought me into DIY? I had an evolve, it broke, I started researching and came by this forum… in fact, this forum had only been online for 3 months when I joined. It was back when JP fucked over everyone for the 99th time.
Gosh, haven’t we moved on since then! :partying_face:

I spent ages doing research. An aspect a lot of people look over when starting a new hobby, or even starting their first hobby ever!
There was so much to learn, from esk8 types, what a vesc was, how the heck the whole electrical and mechanical system even worked!

Mistakes

So after 4 months of reading, I finally pulled the trigger, the trigger of mistake.
Buying second hand
I wanted too many nice things at a good price and suffered a lot because I ended up reselling pretty much everything because it wasn’t appealing to me.
In fact, I reckon I lost about 300 euros in total buying stuff and then selling it again for cheaper.

I think the second mistake was not understanding how tax customs work lol.
Being young and having never ordered from around the world, I didn’t really comprehend.
Well, I learnt the hard way because I lost a lot of money this way too. Unnessaccerily because I could’ve adapted to EU vendors, which is what I resorted to in the end.

My third mistake is to blame on myself. I’m someone who has a hard time being happy with what I created unless it’s the best of the best. And then knowing what to call the best.

The Build

I’m happy to say that this wasn’t just a case of buying all the components and then assembling it, but rather a lot of DIY work with some amazing people to get to the final result!
Let me show

Battery Box

This was a collaboration between @Pedrodemio, @ducktaperules, @tinp123 and @Bavioze.

I loved Pedro’s original enclosure he made for Gathering Storm, a watertight 3d printed enclosure that looked good.

i personally hate the aesthetics of a Peli case.

So we did a remix of it and after many revisions by Pedro and Luuk, I finally had the ideal battery box, or at least the one I had envisioned.

v1

v2 (taller)

v3 (cut and added locking system as to access and service the bms if need be)

v4 (improved locking system and tolerances and better aesthetics. also removed all holes except xt90 and xt30)

We learnt a lot in the process, one being: don’t print in ABS lol. The big versions were printed in a markforged X7 and they still failed and warped horrendously with ABS. PEGT or PLA is the only way.

The bottom plate is a 6mm 6082 Aluminium sheet and the top plate 3mm, all CNC’ed by fabulous @ducktaperules. Then 3 holes were drilled and tapped for M6 on the bottom.

The top alu plate got swapped later for a 6mm polycarbonate laser cut by amazing @SabreDynamics.

The plates are screwed into the enclosure with inserts

and using a soldering iron, you press them into the holes. It’s surprisingly strong, especially with 16 m3 screws holding it into place.

The enclosure fits onto the board quite simply. I have three 5mmTPU risers between the deck and alu plate to allow the board to flex.
3x M6 torx A4 stainless steel screws hold it into place.

ESC box

Nothing that fancy :stuck_out_tongue:
i bought a 3DS ESC enclosure for my focboxes but then they died, got some ESCapes, and of course, wasn’t compatible.
I removed the top plate, 3d printed a file that @tinp123 made for the ESCapes, @Bavioze 3d printed the enclosure part and modified it to my requests while also doing some magic :smiling_face_with_three_hearts:

Motors

my 63100 got the usual treatment of

  • bearing upgrades to some NSK DD sealed zoom zoom balls™
  • battle hardening with epoxy+microspeares+blue mica powder because why not
  • a weird but very effective filter using sandpaper meant for plasterboard. Works extremely well, i surprised my self lol.

Fuck ups - The Ones Not By Me

I had a lot of components fail on me, I’ve been very unlucky. My foxboxes from @Chibatterysystems blew a DRV on my first ride for no apparent reason. My settings were low (first ride), and I was on a flat ride when I got the ABS OVER CURRENT fault.

Bara was indeed kind enough to send back some monies… tho that wasn’t hard given how much money he earns ripping off all those onewheelers looooool.
Still props to him, it covered for half the repair from European wizard @seaborder.

And then my DieBieMS
oh my god fuck the DieBieMS.
i spent 80euro on it? and spent over 100euro fixing problem after problem. components stopped working, things blew up. Just a nightmare overall that I don’t ever wish upon even my worst enemy.
Again thank you @linsus so much for helping me out and fixing it! So much troubleshooting and hours involved. oh god the memories are coming back…

For the sake of god, everyone reading this, just get an LTT smart bms. I have one now and it’s all you ever need. communicates with METR app, shows cell voltage and health over Bluetooth. It really is the only BMS along with @SimosMCmuffin Flexi BMS that’s worth buying. Definitely get a Flexi bms if they are in stock, nothing better exists as of now.

Oh and motors… i had my fair share on motor issues. I won’t nick pick about this too much but my No.1 advice is, when battle hardening, don’t remove the shaft.
If you can get both grub screws out without stripping them, then put them back in without the shaft spinning later on, then you are as lucky as Shelly Woods

Contraversial Wheelchair Crash

:rofl:

Seriously i added 648 loctite, waited 48h, and the shaft skipped like a mf. I had to drill the shaft to make a hole, use drill the grub screw out because that ass hole wasn’t moving with the amount loctite i put, re thread the can, use an m4 grub screw and bang

So do your battle hardening with the shaft in place, it will save you so much trouble.

Builing Pics

Just some random pics and sketches i did to get through my build.

Qwerks and Tricks

I wanted to add a bell to my remote, the Maytech waterproof one.
Having an electric horn was too complicated as i didn’t have a remote receiver with different channels.
So i came up with this super cheap idea that ended up being so practical.
You need

  • 1 ‘‘T’’ type bike handle bar extension like this one

  • 1 M5/M4 x 10mm flat head screw with it’s nyloc nut
    image
  • 4-5mm drill bit
    image

Step 1

When you open up the remote (by removing the 5 screws) you end up with this.

Step 2

This is the hard part.
You basically have to approximately drill the plastic cover so the bolt head sit’s here

The best way to do this is to take a maths compass and use the right screw hole as the center, and make the radius you want, then draw it on the plastic cover, guestimate where on the line you need to drill and voila.

Step 3

Disassemble the T handle until you have only this ( 1 m4 bolt is holding the two parts together)

Drill one cap off centred . This is super important otherwise it will cover the power button lol.
Add the bolt and nut then screw the handle back on the cap.

You don’t have to add a bell, you could add a light or whatever, that’s the coolest thing!

I added I really nice bell made by the bogans down in Straya called the Knog Oi. It has the most amazing ring

!

(yeah I need to change the vinyl as it doesn’t suit at all rn)

Another thing to note is that all the bolts on this board uses

Torx :grin:

Yes, i just earned an instant like from Brian :rofl:

Just show us the Build ffs

Yes yes well here are the final results

And this is the final version

added led lights with a Bluetooth module… it has 200+ presets!

Thanks to all those that read from top to bottom! Yes, that was a long read hehe. I always try and make my threads exciting and funny to read, including detail on how I did things.
Hopefully, you learned something and enjoyed reading!

And I just want to say a HUGE thanks to the community. I’ve learned so much, thanks to you all, and had such a fun time!
I have more projects soon to come as well so stay tuned!

And I have a special “Thank You” post below to those that really made this build possible :point_down:

Cheers and Peace :metal: :v:

Good work duder! Hell of a write-up. I love that the “vanity pics” is your board covered in mud, as it should be. You’re definitely very detail oriented and it shows in the final product.
I’m not sure how I helped other than a decent dick joke here and there, but thanks for the shout out none the less.

Amen when it comes to motor can grub screws. An off-center can is the no. 1 reason I end up replacing motors. Motor manufacturers really gotta make the axle turn into a plate you can bolt the can to or something, grub screws clearly ain’t good enough, and secondary bearings have their own issues…

Excellent write up! The battery case came out great.

I have the 3d model of the top of that remote that I made my portal gun out of if it can be of any help for your bell.

Thanks for showing the inside of the remote, never opened it lol.

pfff you helped me at a certain time dude! Like when you lent me the money :smile: I thank you for that. Really.

Yes i hope so! :handshake:

Quality guy deserves quality shoutout. You made me laugh more than once i can tell you that :rofl: :rofl:

So true. A good motor is what’s lacking nowadays i feel. We got a small smart bms (flexi), we got an abundance of wheels, a plethora of vescs (fight me frank), ten dozen different decks, a multitude of trucks, worldwide known battery builders from across the globe, and 360 different drivetrain possibilities, yet we still can’t find a motor that

    1. Doesn’t cost an arm and leg
    1. is waterproof/resistant
    1. Doesn’t overheat
    1. Comes in many different KVs
    1. Has good bearings

Pretty frustrating imo.

ooooo portal gun. that’s what i need when the cops try and stop you.
My bell solution is doing well for now! i though about adding an 18650 inside to power either the remote or some lights. We’ll see what the future brings!

Bruh. You cant say some shit like that and then NOT link that video you took of the sound.

Also totally forgot the Settings i use.

So with a 5.1 ratio with 8’’ wheels and 140kv, i have a really low top speed, but some pretty insane torque… i should be able to do a wheelie if i balance my self right… I’m currently practising hehe. I do wish for higher speed but this way if i crash injuries are far less exponential.

I average between 20-23wh/km and i weigh ~63kg geared up. I live in the mountains but i was in Spain 3 weeks ago and on flat road at max speed i average a mere 16wh/km.
The board weighs just shy of 25kg btw so pretty impressive consumption rating!


Motor Current Max 95A
Motor cCrrent Max brake -70A

Battery Current Max 75A
Battery Current Max Regen -40A

Traction control > ON

Sensor Mode > Sensorless (I don’t run HFI because funny enough i get no motor jitter, presumably because of the high torque setup.)

PPM Control Type > Current


I’ll share some metr logs soon! I don’t have any worth sharing yet.
