Electrongboard DIY
Good day to all. Today I will tell you how to make an electric longboard with your own hands. The result of the whole assembly was a board with a maximum speed of 32-35 km / h, a power reserve of 25-30 km and a weight of about 8 kg.
Parts (which I used):
1) Deka (made to order)
2) Paris 180mm tracks
83mm wheels
6mm aluminum bracket
Pulleys: lead - steel, 15 teeth; driven - 3D printing (nylon), 40 teeth
3) VESC controller
4) Battery 10S4P 18650 LG HE2
5) Motor Turnigy SK3 6364 190kv
6) Transmitter and receiver GT2B / mini remote
1) Deca
There are plenty of options for what to make a deck: plywood, veneer, carbon fiber, fiberglass. You can also take ready. The main thing is to be as tough as possible. If you use the battery from the 18650 unit, it can break if the deck is too flexy. In my case, the deka was custom-made for my measures.
2) Tracks, bearings, wheels, bracket, pulleys
The most common trucks among self-made longboards are Caliber II and Paris Trucks, because on them you can find the largest number of ready mounts.
Wheels should be taken starting from 83mm (on my board - 83mm), because it is more convenient to attach pulleys to them due to the presence of “spokes”.
Pulleys are usually made of steel / aluminum, or printed on a 3D printer. The most common profile pulleys and belts - HTD5M. For a board with one motor, it is worth taking a 15mm wide belt, with two motors - 9mm.
Brackets can also be found ready-made, or do it yourself. I made my bracket myself from 6mm aluminum, and then I welded it to the tracks.
3) Controller (ESC - Electronic speed control)
The controllers can be used differently - starting with the cheapest aircraft-helicopter-boat RC controllers (from $ 17), ending with VESC (from $ 100), which was designed specifically for longboards.
I used VESC because already rolled on the helicopter controller. What are the advantages of VESC:
- Smooth overclocking
- Availability of brakes, regenerative braking
- A bunch of settings of everything and everything (current, voltage, max revolutions, acceleration / deceleration curves, etc.)
- Telemetry with overlay on the phone
4) Battery
Batteries usually use either Li-Po packages from their RC stores, or Li-Ion-assembled 18650 high-current components. In my case, I used a battery of 18650 LG HE2 10S4P 360W * h.
5) Motor
Standard in electric longboards have become brushless motors with sizes from 5055 to 6374. These motors differ in weight, dimensions, power and kv value. kv - number of revolutions per 1 Volt. For boards with a 6S battery, it is worth taking motors 280kv and less, for boards with 10S - 200kv and less.
More precisely pick up the motor, pulleys and batt will help this calculator . I chose for myself the 6364 190kv 2450W motor.
6) Transmitter and receiver
There are quite a lot of longboard consoles now, but the most reliable consoles are the GT2B (on the left in the photo) and the mini remote (on the right in the photo). Those who are not satisfied with the size of the GT2B print for it a more compact package on a 3D printer (BadWolf GT2B, Mad Munkey v1 GT2B, SPARKLE v1.0 GT2B) and swap all the electronics into it.
Assembly:
We fasten the pulleys to the wheels, put the bracket on the tracks, we put the wheels on the tracks.
We solder connectors if some were not soldered. The battery is connected to the controller, the controller to the motor. So that you can conveniently turn on / off the board, you can turn the anti-spark switch on.
We shove all the electronics in a convenient box.
