Hey, everyone. A couple years ago, I never would’ve imagined I would be building an electric skateboard (or even own one), but here I am going full bore into a build. The wheels arrived in the mail yesterday, lots more is arriving today, and more will continue to trickle in over the next few weeks (and beyond). Here’s the synopsis.
- Longboard—I will construct this myself. Multiple plies of 1/8" Baltic Birch, carbon fiber, Purpleheart veneer on the top and bottom (not my first choice, but it’s what the local supplier had), epoxy, vacuum bagged, strips of black grip tape on top, enough for grip, but showing the veneer between strips. The board will have dual cutouts. I’ll need to take some measurements after I have all the parts, but I’m leaning towards cutting drop throughs just so I don’t plummet to my death if I fall from an excessively towering board. Also, would like the extra stability from being lower. We’ll see if that works out.
- Ordered lots of parts from DIY Electric Skateboards—218mm TorqueBoard trucks, two 6374 motors, two VESCs, the TorqueBoards 2.4GHz remote. I’ve actually ordered the 3D printed case and all other parts for a DIY Arduino remote (found on this very site), but am in kind of a time crunch and so won’t build that for a couple months. Besides, I’ll have my hands full just building the board, so better to use the factory remote to start out with.
- Wheels—107mm Abec11 SuperFlys. Got them in the mail yesterday. Holy guacamole they are huge! I’m really looking forward to the smooth ride they should provide though.
- Motor mounts are from our very own Marc. I’m planning on making some minor modifications to them, but they look like great mounts.
- Batteries—I’ll be using Sony VTC6 18650 batteries. They’re rated at 3Ah and 15 amps continuous, but 30 amps continuous until reaching 80° Celsius. I’m going to build individual 12S packs joined with multiple strips (4-5?) of pure nickel wire. 10 gauge silicone wires will come out of each pack with 5.5mm bullet connectors on the ends. I’ll build up multiple 12S packs each of which will be wrapped in heat shrink tubing so I can just plug ‘n’ play as many of them as I want. I’ll start out with 6, for a 12S6P pack. If I want more juice in the future, I can just build up more packs and plug them in. I would need to build a new cover, though. (Some say that 12S is a bit too high a voltage for a 190KV motor, but the DIYElectricSkateboards.com told me there are many people running their motors on 12S with great success. Also, I know some say you should build up P first, then S. However, there is also the other side who say S, then P, or that it doesn’t matter, so that’s my choice.)
- No BMS.
- For the bottom cover, I plan on making a mold and vacuum bagging carbon fiber.
Did I leave anything out? Probably, but I’ll post more as I get going. I’m also planning on putting videos of the build on YouTube when I’m done.
By the way, my big motivation for building this board is to tow a wagon around at Oshkosh (one of the biggest aviation events in the world, the entire last week of July). I figure I may go 20 miles in a day, or more—towing a wagon with my camera gear, drone, lawn chair, umbrella, etc., in it. Should be interesting.
