Last year I build my first electric longboard, with inspiration and information from you guys! Thanks for all the amazing builds and information avalible on this forum, its amazing
I have been riding my board for a year now, and borrowed it to my cousin a few weeks ago. He road it for a few miles, and of course fried all the electronics That gave me a new opportiĂșnity to create something new and hopefully better.
So far my build will contain:
1 Turnigy SK3 6374-192kv motor
30 Samsung 25R 2500mAh (10S3P)
1 40A 10S BMS
1 Vedder Antispark Switch with 40A/50A fuse
4 83mm ABEC 11 clones
Custom remote with NRF24L01
A VESC 6.4
Custom deck
15T and 40T HTD pulleys and belt
The deck is designed in Inkscape, and milled out with my X-Carve from Inventables - a most usefull machine! The deck is made of some glulam I had in stock.
I am planning to cut out som risers for the trucks in some high quality wood, and making a motor mount out of some 5mm aluminium profiles I have lying around.
What do you think so far, anything I could improve? Looking forward to hear your opiones
Iâm interested in how the risers come out. I need me a pair also. And very nice design with following the grain of the wood. Also how thick is that board?
It may be advisable to set an Erpm limit of 60,000 when setting up your vesc if you go with the vesc-x
Using that high a kv motor with a 10s battery may otherwise lead to some issues.
If the PLA version fits I will go for another material. However printing in Nylon is pretty expensive, maybe ABS could do the job? As far as I know ABS is much stronger than PLA
Hi Oskar, good to know that I am not alone on my electric longboard in Denmark! I live in Aalborg, how about you? Could be fun to meet
Lyder spÊndende med din webshop ! Hvis du har brug for noget hjÊlp med opsÊtning/udvikling mÄ du sige til - jeg arbejder til dagligt med webudvikling/design
Itâs looking oddly similar to my build so far. You might try and router out the edge of the deck a bit on the underside to give it kindof a wheel well. Itâs been working out really well on my. Iâve got 97mm wheels and only 1/4 inch risers
As for printed pullys Iâd have someone see about cnc milling some out of aluminum if itâs anything like my motor and gear covers that shit will vibrate itself to pieces.
It seems like this has been addressed and fixed w/ the VESC 6. Where the VESC 4.xx was pretty much guaranteed to kill the DRV chip over 60k ERPMâs (thanks to @Chaka for calling out this limitation and sharing here).
I just read a pretty lengthy post by Ben on his forum regarding the VESC 6 Beta. Getting close finally! And some motors over 150k ERPM it seems w/o issue. Much higher amps possible, and just seems a ton more robust!
The possible downside if you were going to build your own (you made your own deck - iâm guessing you might try reflowing your own VESC) - Vedderâs BOM/Gerbers arenât yet available during the âBetaâ . But you can see if there is room to join the beta group by contacting @trampa (Frank at Trampa) to get on the list. Trampa being in the UK, and you in Denmark - it should be a bit faster for you vs those of us in the states.
If you go printed pulleys - you should go 15mm wide belts for more contact, and hopefully you are light. Being in Denmark - iâm also guessing itâs pretty flat where you ride?
I had a single 9mm setup w/ printed wheel pulley for my GF - worked OK. Nylon IIRC, not PLA, but while she could ride it - it would skip terribly for me no matter how tight i ran the belt. Not just at faster speeds⊠So while it can work⊠I would still go w/ Aluminum if you can. Look for @Titoxd10001âs 15mm 15/40 setup if you want to gear down (less top speed, better accel and torque) w/ some nice aluminum gears that wonât break the bank $ wise. Unsure if shipping to EU will be prohibitively expensive thoughâŠ
Thanks for the tag. @Deathjunior I have aluminum 40t pulleys designed especially for 97mm flywheels. I also have steel 15t 15mm pulleys. They will be available for purchase today or tomorrow shipped directly from Europe at a very reasonable price.
It is indeed very flat in Denmark, however we got hills now and there Maybe I should go with a steel or aluminium pulley instead. I just find the idea of 3D-printing parts very appealing
Thanks, thats good to know! I have already contacted Frank, and I believe he added me to the mailing-list ! So I am waiting to recieve an e-mail from him!
@Titoxd10001 I am very interested in one of your kits, does it fit a 83mm flywheel? Thanks
Looks nice, do you have more pictures of your board?
Iâm good lol I run cnc aluminum wheel pulleys I just use an abs 3d printed spacer to make them work on my 97mm flywheels. My motor pulleys are steel. Iâm going to rework my motor covers and print them from pla in order to investment cast them in sand.
@solidgeek
I actually have a motormount set including pulleys and trucks. I am willing to sell it to you for DKK600? It is about half of what I payed for them from DIYâŠ
I have just recieved my 40T and 15T pulley from @Titoxd10001! Looks great, and fits my ABEC11 clones perfectly - thanks, you just saved me a lot of enginering !!!
Thanks, but I have been working on a motor mount myself ! Just finished the 3D-sketches today, and been trying to carve the design in aluminium on my CNC. It came out very good, however I did not have the time to finish it completly.
So, itâs been awhile since I had the time to work with my board, however since the VESC 6.0 just has been released for Beta, I simple had to finish the mechanics (motor mount etc.). Instead of the aluminum motor mount I had been working on, I decided to try something new. I recently bought a 3D printer, so I thought it would be fun to try and make an all 3D-printed motor mount. And I came up with this design (inspired heavily by the one from DIY).
It consists of to parts, heavily interlocked and reinforced. The locking ring fits perfectly on a caliber truck and is tightened by one 5mm bolt and locked in place with another 5mm bolt. The whole motor mount fits right over the caliber-ring, and is locked in place with 1-5 4mm bolts. To make sure the motor mount doesnât bend I have made room for two solid 3mm*80mm steel rods, that slides in from the tip of the motor mount.
Sooo⊠I printed it with some high quality carbonfiber reinforced PLA in about 4 hours, and it fits perfectly
It feels incredibly stiff and robust, however if it will last more than a few miles, I do not know Hopefully it works untill I learn to push myself ;)! Iâm looking forward to recieving my VESC 6!
If anyone wants to try to 3D-print the motor mount themselves I would love to share the Autodesk Inventor / STL-files
That looks awesome, the way you reinforced the motor plate is inspired. Iâd like to print one if these in ABS and give it a run, if you donât mind sharing.
