Hello everyone, My name is Andrew. I am currently a 1st year Mechanical Engineering student at the University of California, Santa Barbara. Most of the students here commute on bikes and longboards, and I thought it would be very convenient to have an electric skateboard to get around the campus. The bigger focus of this build is to create a project that would look good on my resume, and to a great conversation starter. I planned on building it over the summer so I did some intensive research in the past week or so. I understand that to build a decent board isn’t going to be cheap, but I am somewhat going to treat this as an investment for future opportunities. So my budget is set to around $1000.
The following are the parts I have decided to use.
From @torqueboards ($528.97 plus shipping = ~$550?): Dual Motor Electric Skateboard Kit, which includes: (2) 6355 190KV (I am assuming is the 6355 190KV at 2500W motor) (2) VESC (I think is TORQUE ESC VESC ® BLDC Electronic Speed Controller) (1) Male to Male Connector (1) VESC Canbus Connector (1) Dual VESC XT90 Parallel Connectors *the assumptions were made based on the prices, @torqueboards please let me know if I am wrong Longboard Bearings 8mm 2x 36T KEGEL Pulley Combo Kit Looking to get the 13T motor pulley TorqueBoards 2.4ghz Nano Remote Controller
From Hobby King (~$140): 4x Turnigy 5000mAh 4S 25C Lipo Pack Planning to put 2 in series and 2 in parallel to get 8S 10000mAh
For the motor mounts, I have some pretty good machining skills, so I think I will be able to machine them myself on a mill. (I might need some drawings)
As for the deck, I am looking for a deck that has similar concave (and maybe flex) to the Vanguard (the Vanguard itself is wayy to expensive), but I am not really in a rush to decide on a deck because I want to see how much space I really need to fit all the stuff underneath it. Decks that I am looking at: Madrid 2017 Weezer Longboard Skateboard Deck w/ Grip ($104.95) Sector 9 2017 Mini Fractal Longboard Skateboard Deck w/ Grip ($93.95) Sector 9 Lookout Longboard Skateboard Deck w/ Grip ($84.95)
And the enclosure, I was planning on 3D printing a two part enclosure after finding out how much space I need.
None of this is 100% set, hence the reason I am reaching out to you guys to get feedback. I want to build something that is decent quality and would at least last me through 4 years of college. My visions for this board is to get around 22 - 25 mph top speed (not crazy fast but decent), and get around 12 - 15 mile range. It would also be nice if I could get a BMS connected to my batteries so I wouldn’t have to worry about the balance charging thing.
Like I said earlier, I want this build to be a project that I could put on my resume. Which means the more DIY I do, the better I can demonstrate my skills to future employers. I have seen many people on this forum who built their own battery pack, but I think for me that might be a tad bit advanced. But should I custom make my own wheel pulleys rather than buying them?
PLEASE let me know what you guys think about what I have so far, what I need, and the concerns I have. THANK YOU for reading all this haha.
