DIY Electric Long Board

Why DIY?

In the past couple of years, motorized skateboards have exploded in popularity, and for good reason. They're fast, efficient, and the perfect futuristic gadget for easy transportation. Back in 2015, I decided I wanted to build my own for under 600 dollars, with the intention of it having the same performance and speed as a standard boosted board which were and still are priced well over 1500 dollars. In no means am I criticizing boosted board, as they make a fantastic product for the price, I just wanted something to build for myself on a college student's budget. Turns out this board completely exceeded my expectations with a top speed of 25 mph, 30+ mile range on a single charge, and extreme durability.

Total Cost -

Around $550

Previous Design  Version one of the board utilized a plywood enclosure with an aluminum plate to cover the electronics. The two 5000 mAh lipos were strapped directly to the deck along with the ESC. Charging was done through the two yellow xt-60s, while the black xt-60 was used as a jumper to connect main power to the esc. This avoided the current rating issues associated with mechanical switches, and was a cheaper alternative to a electronic switch for main power. Although this setup looked nice, the enclosure was prone to cracking and I decided that I would have to vacuum form my own abs enclosure.

Although the final version of the board is not perfect, the abs enclosure turned out to be a huge success with its durability and low profile. The same electronics have been utilized in the final version pictured here, apart from the latching push button switch.

Pictured here is the latching push button switch which powers the BEC for the receiver and the voltage sensor to the right of it. The same xt-60 jumper set up for main power was used here. Voltage reading is only from one battery because of the sensor's 30 volt peak, which would be exceeded when the 8s configuration is fully charged.

The DIY electric long board single mount has completely exceeded my expectations, as its lasted well over two years and roughly 1000 miles of hill climbing and other abuse.

Arguably the only thing preventing this board from having performance equal to a pre-built one is the outdated ESC. The YEP ESC used here has outdated software meant for model aircraft, making braking only reliable at very slow speeds. I plan on upgrading to a VESC long board ESC in the future to make this beast safer to ride in crowded areas.
