Endless Sphere

Hmm,I am not sure if I understand. Do you mean that you need to connect the control board to a computer with this usb tool to change the default settings?

I have done some work on the bike too. Let there be light: https://i.imgur.com/immGqZq.jpg https://i.imgur.com/NMNojLQ.jpg No brake light yet though. I ordered a switch with some other stuff, but didn't get it. A problem with inventory. https://i.imgur.com/50sIGhY.jpg A little cad* work. (*cardboard...

Maybe I should show my charger building fail here too. I plan to build a charger by series connect 2 huawei R4850G. Without any regulation they give about 54V and 50A, that is a bit much for me.. https://i.imgur.com/ZtIqPJf.jpg This is what they look like. https://i.imgur.com/Ylnc1NE.jpg Here is a c...

I went with a quick fix of the key: https://i.imgur.com/OuwWNM1.jpg It should be difficult to bend it now, and so far it has been fine :wink: The wear on the upper corners of the battery covers started to be a problem: https://i.imgur.com/Q7Jpp5J.jpg I marked out the sizes of these: https://i.imgur....

It will be interesting to see for sure
How about the dyno? Would´nt it be perfect to test there?

I am not sure how hard it is, but you can always try. Maybe you will need an angle grinder or something.
There are nothing sensitive in the axle. I would like too keep it to mount torque arms, but on such a small motor it might not be needed.

How is the progress, it has been a long time since the last update

Interesting build to follow

Yes, this is about what I mean. Only difference is I would like some material on the outside of the clamp, around the axle. That will still keep the wheel in place if you manage to brake the clamping bolts or something. I don't know if it is really needed, it is more of a "gut feeling". It would be ...

There are no connection between either positive or negative output and either of the can bus wires, so I guess it should be safe.. At the moment I am a little low on psu:s, so I cant really test :roll: Luckily I bought extras of the control board. It seems to work fine at adjusting the voltage outpu...

I would guess that you get a little leakage through the mosfets in the bms, assuming that the switch is to turn off the bms.
I think that is normal.
Test with a small light bulb or something as a load on the terminals, if you still get voltage it is a problem.

I wonder then if it is safe to parallel the can bus from more than one psu? I plan to run 2 psu:s in series, and control them both with one control board over can bus. So the can bus will be connected parallel. From my experience with can bus it should be almost indestructible. You can short them to...

I got the control boards today. I went looking for a power supply for the board in the psu. I found the fan had a steady 12,7v, I thought that would be perfect. https://i.imgur.com/99oUnTg.jpg https://i.imgur.com/KH7XDN8.jpg https://i.imgur.com/Ylnc1NE.jpg Well, I connected the board to the 12,7v. I...

measuring the voltage accross the batteries disconnected, I get 66v. measuring across the batteries whilst connected, I get 5v or thereabouts. Do you have a bms? It sounds like a bms that turns off for some reason. Can you test the output with light bulbs or something? Can you read or mesure cell v...

There is a Chinese guy selling the programmer boards for about 12$ on Taobao https://2.taobao.com/item.htm?id=565948826876&ft=t&toSite=main If you are having difficulty ordering it then you can use a third party service like Taobao Focus. They will order it for you and ship it to you. https://buy.t...

Were you (or someone else) able to find it or something simular? I should soon have to modify 2 of these psu:s, it would be nice to be able to adjust them without the programming. I do not know,,, only china controller.. now I have contact to get it... I have two... no used for now... https://drive...

could you answer or call me and solve the problem with bac8000.
You took my money and sent a product that has defects and cannot be reprogrammed.
It's unprofessional and embarrassing.

Are you talking about the threadstarter or ERT?

You make nice parts, but I really think you should make it so you can clamp the axle in place. Even if it is tight now, it will probably start to move sooner or later. I would like something like your first design, but with clamps on the inside. Then you would have something that still holds the whe...

He got banned from the site, and did as much damage as possible before and after. One thing was deleting all pictures, so I don't think he will post them again.

I'm sure interested in that sprocket, pm sent :) This is some damage from last ride, it is from a crash. But I have no idea how it happened: https://i.imgur.com/9APH2Bm.jpg https://i.imgur.com/wnjqEOO.jpg I thought it was well protected where it is mounted, but apparently not enough. I am thinking a...

Larsb, Interesting :) Does it fit a 428 chain, or what is your plan? I thought your apt96600 was broken, 30s sounds like a plan :wink: My chain rattles when not loaded, and wines when I hit the throttle. You cant really sneak around like with a hub, but it is silent compared to gasbikes. No videos, ...

Well, I have 10 tooth front and 70 tooth rear. It is the biggest rear (and smallest front) sprocket I have found. I have been thinking about going 11 tooth front and 75-80 tooth rear, custom made probably in that case. But I don't know how much difference it would make? One advantage with doing so i...

You did a great job with your build! Very well documented , too. I have to say my favorite image is the one where the little kid is pushing a toy lawnmower around the campsite. Get that little man a toy dirtbike :D I finally got what you mean,it seems like I don't know what is in my own pictures :l...

What kind of chain are you running? 428? Im running the same controller/motor in an ATV and installed the cheapest biltema 428 chain as a temporary solution (I see your biltema sealer on a picture, so I guess youre from Scandinavia somewhere :) ). To my big surprise it is almost the exact same tens...

Thanks,it is always good to know that people appreciate the updates. I don´t think the kid with the lawnmower has anything to do with this thread? :? There is not a lot of news about the bike, but I was riding another endurance track this weekend. 8km of mud, mountains, rocks, roots etc. I did 3 lap...
