Today I inflate my tire with more air and recharged the battery fully. This time I drove the board on stone and got like 75 min out of the battery. I was happily surprised with this result. Because it means if I drove like 5 km/h, I will have 6.25 km of range (4 miles). This fits my expectations! Thank you very much for the tip!
Also I will search for good washers that will fit the bold and the aluminum.
Got my first flat yesterday 
Gave me a mini heart attack thinking that a cells overpressure protection blew at first 
What pressure do you guys run? I loaded up with 3 almost 4bar (max for the tire) but I suspect that its a bit to much for the hose. I haven’t had time to check where it bursted yet.
Alright So I got my 2 hoverboards in. One of them had “samsung” cells, cant tell if they are real yet but the outside said they were. but the voltage was at 20v so some slow charging and the cells are back to normal. and I tested the hoverboard and all seems to work fine. Both of them had the correct motherboard so that was a big bonus. The other battery somehow is completely dead, I measured it at 3v at the plug so I’ll see if I can revive it but if not I’ll just build a new pack. The hoverboard that had a completly dead battery had one of the motor wires unplugged so Idk if that had anything to do with it.
Hi,
New forum member here, but I’ve been closely following onewheel builds on this forum.
A few weeks ago I also started a “Thedirits” build. I went for the Burris tire, as it’s almost impossible to source decently priced 6" tires here, and I wanted a full width (ie. matching the rim width) tire for better stability.
Up to now the build has been going well, I have the full wheel assembly and front/back platforms printed.
Now I’m wondering how did you guys deal with the aluminium rails dimensions ? It looks like the original 3d design is imperial units, but the closest we can source in Europe in metric units does not match perfectly. Especially for the rail height : the design accounts for a 38mm tall rail, while the closest we can source here is 40mm height. So there’s a 2mm gap, which is quite visible in Nathan_3Dr88’s picture :
Did you just print the design as-is and live with the gap, or did you modify the design to compensate for the difference (I’m going this route).
The same question goes with the rails width, but in this case the solution is more obvious, cutting the rails to fit width. I will have to go this route anyway, as the rails I ordered are 40x25x3mm.
post edited to add pictures
I also use 40mm rails and just let the gap be for now. Would be great with versions for 40mm rails I sadly lack the time to design them atm but should be relatively easy to do 
Hello guys!
I have finished my DIY onewheel! I found this project in thingiverse and i decided to do it.
After one week of use I feel more comfortable on it, but when I am near a small climb and my inclination decline the OW couldn’t up.
I have read some tips like to:
Assuming that I haven’t knowledge about batteries my question is, How I can get more torque on the wheel although I’m moving at a very low speed? It is possible?
What is the max A that the board resist?
I await your opinions and advice.
Sorry for my bad english
Cool! Looks great!!
I understand that most of these builds rely more or less on re calibrating the gyro for the “balanced” position to be leaning backward. Did you do this ?
I’m also planning on integrating an emergency landing system, still not sure of the best way to do it, it will probably need so adjustments of the STL file.
Hai,
As you can see I didn’t compensate the gap, but I don’t really care that much about it. I did modify the width of the part for the rail. I used a 40x20x3. If I remember correctly the width of the part is like 1,85 cm or so. I used Fusion 360 to change it to 2 cm.
Which motor and tire is that? Do you have links?
The motor is two hoverboard motors with a 3d printed rim. Look at the top of this forum to see but here is a link to the tire I used
torque at low speed is entirely dependent on the “motor max” current setting. More current = more torque.
Hey guys, what cells would you recommend for a 12s2p battery pack?
If you can fit them this would probably be a good option and what I would build with.
Wow! I love the machined rim. I would have totally done that if I had access to a lathe haha.
So I started with using the rubber nipple thing to activate my Onewheel, but I found it to be inconsistent and not very safe because if you lift your foot off of the button at all the result is you falling off and having a sore day. So I sought out to make a pressure pad, similar to what is used on an actual Onewheel. When scrolling through another forum where they make one wheel with pre-made wheels and vesc’s I found that a lot of people were making their own pads with some copper tape and some Velostat which is pressure-sensitive and semi-conductive material. So using info from this youtube video and other places I made a pad that looks like this.
From there I powered an Arduino nano with 5v from the board and wired everything as pictured above.
If you want a schematic and the code I made a Git Hub for this. I did some testing on it today and it is soooo much easier to get onto the board and I feel a lot more confident when riding that it’s not just going to die under my feet haha. I hope this is helpful and don’t be afraid to ask me any questions!
I really love the idea ! Is the rim tubeless or do you still have an inner tube ? In that case, how did you fit the valve ?
