HACKADAY prize ENTRY: AN electric LONGBOARD

The Hackaday prize is in full swing, as well as that means we’re starting to see all the develops a few choose people have been saving up for the past few months. [yowhwui] has been working on a 3D printed electric longboard for a while now, as well as this develop is truly solid. He already has over 150km on the odometer, as well as the 3D printed parts are still holding up.

The power for this motor comes from a 6374 brushless motor running at 192 kV. This, plus two 4S 30C 5000mAh LiPo batteries propel this longboard to speeds as much as 42 km/h (2.18 Saxon leagues per quarter hour), all while weighing about 8kg.

Since [yowhwui] is utilizing the motor for power and braking (electric motors are neat), this longboard needs to be designed with belt skipping in mind. To that end, he’s designed a drive system with an idler, as well as almost every single part is 3D printed. The very first revision of the hardware was printed in PETG. While PETG was more than strong enough, it was likewise as well brittle. This led to a few cracks. After printing the parts out once again in ABS, [yowhwui] put a few more kilometers on this longboard, as well as there are no instant indications of wear.
