I'll start by saying this was an incredibly rewarding project that I'm able to use every day. If you haven't had the chance to ride an electric longboard, it is like no other mode of transportation, fast, fun, and portable. Commercial electric longboards start around $1,000 which is tough to swallow for a financially struggling college student, thus my expedition started to design and build my own! Plus it was a good way to keep my 3D modeling skills sharp!

This project ended up costing me around $400 since I was 3D print a lot of the components and built my own longboard deck, which you can learn how to do here.

Lets get started!

Step 1: Parts List and 3D Model Download Links

Hands down the most difficult part of this project was figuring out what specific parts I needed, making sure they all worked together, and making sure they were all in stock. I put together a comprehensive list of all the components I used throughout the build process, where I bought them from, and how much they were. Hopefully this sheds some light and helps guide you through choosing components.

Since I also have access to a 3D printer, I wanted to take full advantage of it and save some money. I 3D printed the motor mounts, the gear on the wheel, the electronics mounts, and the electronics case. I wanted to do this right, which meant I needed a 3D model of EVERYTHING on the board. This was incredibly time consuming, but I uploaded all the 3D models I made to thingiverse, so feel free to use them as you please!

<p>Hello I want to use the same 3D motor mount design but a different motor which is 280 KV brushless motor. <a href="https://hobbyking.com/en_us/turnigy-aerodrive-sk3-5055-280kv-brushless-outrunner-motor.html" rel="nofollow">https://hobbyking.com/en_us/turnigy-aerodrive-sk3-...</a><br><br>Will the motor be fit for the same design you assembled?</p>
<p>Hi! I have a quick question to ask, if i get a motor that says it needs 8s-10s to operate, can i use a 6s battery? Im asking this because i cant find any 8s esc and dont want to put out $100+ for one. The motor im planning on using is <a href="https://hobbyking.com/en_us/turnigy-aerodrive-sk3-6354-260kv-brushless-outrunner-motor.html">https://hobbyking.com/en_us/turnigy-aerodrive-sk3-...</a> Thanks!!!</p>
nice build tutorial! I just started to make my own. https://youtu.be/yWeLAkTYFoY (build log)<br>I will try to make the best quality board under 400 $
<p>Great 'ible man! I make a bunch of boards with a vacuum press and many of my amigos have converted to electric as you have but were certainly not the 'documenting' type. This is a great service to novices (and lazy people) that makes the engineering involved with this project managable to someone without a machine shop at their disposal (as me and my friends do, being at an engineering school), albeit requiring the 3D printer. I'm not as confident about the massive use of PLA as you seem to be, but this is great either way.</p>
<p>Thank you, that means a lot! I was really frustrated with how hard it was to find information on how to build one so I wanted to be really explicit with the tutorial. I printed the motor mount at 75% infill which makes it really solid. The first version I printed was at 40% and cracked after 20 miles or riding but these haven't budged after 50 miles. Thanks again for looking!</p>
<p>im doing a science research project for my senior year and definitely going to build one of these! You inspired me man! Thank you</p>
<p>That's awesome, it's a really fun project and definitely helped strengthen my engineering and design!</p>
<p>Would there be any advantage to doing this with two motors? How well does the braking work?</p>
<p>Also is there any way you can make a smaller RC transmitter?</p>
<p>You can just use an arduino. The motor controllers work with regular PWM, or &quot;servo-code&quot; outputs. Get a no-name arduino for $4 each on ebay, if you want wireless, get a $1 radio trans/receiver (433mhz or 355 mhz as examples, get the legal frequency for you country). It should be about the easiest thing to code, just a few lines since you only have one output. That would be under $10, and you could program it to have a steady acceleration throttle curve, or anything fancy you want.</p><p>You could also use brushed motors, they have dirt cheap (like $5) motor controllers, and just use like a drill motor (but you would have to re-cad it, and I know not everybody has used CAD software before, but it is a cheap alternative).</p><p>I'm planning on doing something similar, but going for all wheel drive, twin motors with differentials in the trucks. It will be a while till I get time, cost should be around $45-50 +battery and board choice.</p>
<p>Very true, that's definitely another way of doing it. I've even seen a video on someone literally using a lithium ion powered drill attached to a wheel to power it. It would be a cool project to write the software that controls the motor!</p>
<p>Yes! Someone made a 3D printable case modification for the RC transmitter and cuts the size in half, it's the next thing I'm going to make:</p><p>http://www.thingiverse.com/thing:922378</p>
<p>Two motors means higher torque, you'll be able to bomb up steep hills, have crazy acceleration and a higher top speed. The braking system works great, I'm able to program the ESC and change what the max amount of braking force it. It's really helpful when you're going a little too fast for comfort. </p>
<p>This is a pretty awesome design, you did a good job. I particularly like the mount where it clamps onto the trucks. I know I would take cruising in style over walking any day! That's no joke about the &quot;too fast for comfort&quot;, your hitting around 20 mph with that board. Excellent job!</p>
Amazing! Love the video.
<p>Thank you!</p>
Great build. Are you still able to use the board normally if say, the batteries give out?
<p>Thank you! Yup, although there is still some resistance in the motor that makes it significantly tougher to cruise, it's basically constantly slowing you down. Definitely possible to ride it if batteries give out, it's just not a pleasant as if you were on a board without a motor.</p>
Wow, nice job dude! I'll make it and I'll post photos! <br><br>Thank you!!
<p>Thank you! Please do, I'd love to see it!</p>
Thank you for the inspiration to
<p>No problem, I'm glad to hear it inspired you! </p>
<p>hey matt you have inpired me for this job iam have been trying to make my own electric long board all year and i am also doing this for my year 12 majour work </p><p>if you have any other tips and anything that could help me would be really help full</p>
<p>That's awesome, I'm so happy to hear that! Let me know if you have any questions or run into any roadblocks, I'd be happy to help!</p>
<p>superb. it is something I was looking for! thank you!</p>
<p>Thank you, I appreciate the kind words!</p>
<p>cool dude</p>
<p>Thank you!</p>
