Introduction: Make Your Own Electric Motorized Longboard
In this project I will show you how to build an electric motorized longboard from scratch. It can reach speeds up to 34km/h and travel up to 20km with a single charge. The estimated costs are around 300$ which makes it a good alternative to commercial solutions. Let's get started!
Step 1: Watch Part 1 of the Video Series!
During the first part I will show you how to build the longboard itself. The process is rather simple but you can always get yourself an already completed board from your favorite seller. The method of attaching the motor and the electronics later on stays the same.
Step 2: Board Template & Parts List for Your Homemade Board!
Here you can find the board template that I used during the video. Don't forget to print it out as a poster otherwise your board will be a bit small.
The materials you need for your own longboard are the following (affiliate links):
Home Improvement Store:
2x 55x122cm 4mm thick beech plywood
1x 55x122cm 6mm thick beech plywood
2x 550g waterproof wood glue
1x wood glaze (walnut)

Step 3: Watch Part 2 of the Video Series!
In this second part of the trilogy I will show you the mechanical build. This includes attaching a gear wheel to one wheel, milling an adapter to connect the motor to the already mentioned gear wheel and finally mounting the cases for the electronics onto the board.
Step 4: Adapter.svg File & Parts List
Here you can find the .svg file I created for the adapter. Open it with Inkscape in order to print it out as a template or to modify the design.
You will need the following parts to complete this step (affiliate links):

Step 5: Watch Part 3 of the Video Series!
In the final part of the trilogy I will talk about the wiring inside the cases and how I created a remote control from an old Wii nunchuk I had laying around.
Step 6: The Wiring!
Here you can find the wiring diagram that you need to follow in order to achieve the same functionality. Make sure to only switch on one battery at a time. Otherwise you would charge the empty battery through the full one and the ESC might not function correctly. But don't worry nothing would explode if that mistake happens.
For the wiring I used 12AWG red and black wire: Here is an example: http://rover.ebay.com/rover/1/711-53200-19255-0/1?...
Step 7: Build the Transmitter and Receiver Circuit!
Here you can find all the schematics, code and board layouts that I created for the transmitter and receiver.
Make sure to upload the Attiny Sketch to your ATtiny45 if you want to finalize your nunchuk remote control.
