THE CYBOARD | Stainless Steel Unibody | 100D | 16s6p TM3 | MT6374 140kv on Kaly Helicals|

About a year ago, Tesla unveiled the Cybertruck. I started and stayed firmly in the “it looks cool” team while everyone kept flip-flopping on what they thought of the first full stainless production vehicle since the Delorean. A month or two later I was bored and thought of how cool it would be to have an esk8 built like the Cybertruck. I was also inspired by @moestooge’s steel tube + “bucket” builds.

So I loaded up inventor and made this horrendous model

I played with the idea on and off for a few more months until I decided actually try. I ordered some laser cut parts from SendCutSend (they paid, sponsored?) and see what happens. This was the result:

This design did not take into account how it would be assembled so each panel was separate. This was simply to see if the idea was worth pursuing at all. I liked how it turned out and started to do research on bending. This led me to leave Inventor and switching to Fusion360. With the new software and some help from Staloff Brothers Custom Metal Fabrication in Jersey City, NJ I was able to create this.

This was another proof of concept and had basically zero attention to detail. We ended up using it as practice for welding the final version. Speaking of the final version, here she finally is

None of this would have been possible without my buddy Frank. He welds MRI machines for Phillips, I’m lucky to have a friend as skilled as him. You should follow his welding page if you’re into stacking nickels.

Okay, she’s not really “final” but structurally she’s 80%

I didn’t want to make this project public until now for two reasons:

1: I was not confident in getting someone skilled enough to weld this together

2: So you guys don’t talk me out of it

Here’s what’s left structurally

  1. Measure out the top and order a lid piece
  2. Secure the lid somehow to the rest of the body in such a way that it adds rigidity.
  3. Tool-less removal
  4. Prevent rattle from the lid
  5. Insulate the inside
  6. Polish the outside and get rid of the welding marks
  7. Design and fabricate truck brackets

About the truck brackets…

Here is my current idea ready to be made. I designed these before I had the welded deck in my hands. This will lead to changes, and I want your input here.


On to the electronics & etc

Specs:

  • Modular 16s6p with Tesla Model 3 cells 1659Wh
  • Stormcore 100D
  • Custom Maytech 140kv 6374 Motors
  • Kaly 4:1 Helical Gear Drive
  • Kenda 200x75
  • 3D Printed Spacer
  • Trampa Superstars
  • Single Trampa Truck for the front
  • White COB LEDs in the front opening and red in the back.
  • DAVEGA raw metal
  • Hoyt Puck probably

Closing notes

I’m concerned about my remote being able to connect in this faraday cage I built. I’d appreciate an elegant way to externally mount the receiver. Also, I like that the top lid will be modular

Dude. This. Is. Awesome. Mad respect, not just for the fact that you built this chassis, but the fact that it’s something new, something different. If I saw this in person I wouldn’t think “Stooge Copy.” It’s a totally different take on the chassis board design compared to Moe’s, and I love it.

Thank you so much! Speaking of stooge, I plan on throwing some NKP’s on this thing next year when I get some more money.

Do it! Can’t wait to see how you like them.

Looks great! I can appreciate that rigidity is key for a design like this.

Is there any concave in the deck?

How heavy is the deck by itself?

Absolutely none. May add something to help in the future.

Very. I have yet to weigh it. IMO after a certain weight it doesn’t matter to me because I’ll never pick it up. I roll in and out of my garage.

1st Update because I’m so excited

I started grouping cells and gluing p-groups.

FTFY, just one “L” in Philips, common mistake. I work for them out of their patient monitoring factory In Germany.

Awesome build, I look forward to watching your progress. When you design the lid, you could make a front footstop that houses the Puck receiver and gives a cyber truck cabin vibe.

Great idea! But for the first iteration I’m gonna try to have this be an ultraboard. So I want the top to be 100% bare.

Holy shit dude this is amazing…

Glad you kept it a secret till now because you definitely blew us off with the reveal. WOW!

If something went wrong with this version of the deck, I’m not sure if I would have continued the project. The flat stainless alone is worth around $350. I didn’t want to make the project public until after the welding and only if it went well. And here we are.

3d servisas newest trucks would look perfect on this board

I wish they didn’t need extra holes in the deck for barrel retainers :pleading_face:

With the bracket like in the render it would be perfect though

Is this the same bolt pattern as trampa? Also, it wouldn’t match my rear trucks :frowning:


Progress progress progress!

More progress. I did all the welding and protection on the 4x 4s6p packs that make up the board’s battery.

The brackets came in and they are gorgeous. 1/4in thick stainless steel should be strong enough.
