E-Freeboard Freebord Open source Electric Caster

this video from the time before time

Alright I’m giving up on everything I’ve worked on here and I’m making one of these:

haha acutally looks like his design could use an electric caster wheel, maybe with suspension or a big soft tire… wonder where he could find one of those :thinking:

For international sourcing these look like an identical wheel profile to the JMK ride version. I know someone found theirs like this on Taobao also.

oh while searching I see these

without the nice rounded profile but it could be ground to have it. It is the correct diameter at least.

you know what my dumb ass was thinking that would work. It has no spinning axle duh. Well I’m gonna leave it here for you to see.

Hey guys. I have been away from tinkering for a long time. I have a lot to catch up to. Yall have been busy !
I wasnt happy with the belt system, its hard to have it well tensioned. So i bit the bullet and ordered direct drive motors.
This is where i am so far.

I hope you are all well
Cheers

Awesome! I would love to see something come out of this project, I love riding my freeboard so I’m also looking to electrify it!

I panicked because i realised suddenly that those new motors have a hall sensor connection. And my sliprings only have 3 wires.
I tried running them only with the 3 central wires, and it seems to work.
But anyway a 3d printed flat slipring with gold plated metal rings might still be the best, and flattest, way to go.
If the whole wheel system is tightened with a common bolt like on a freeboard it is probably the least ratlling system.

Did you back this Quinn?
Being the guru in this stuff, what’s your opinion on it? Interested in these (snowboarding background) but never ridden them. Not common here.

I am waiting because I want to see if I could buy it without the battery and ESCs…

It is pretty much just a hub motor Summerboard with more standard electric skateboard electronics.

First assembly looks good. I will tweak a few things here and there but the idea seems okay.but I have no idea hiw strong it is.
Next print will be petg if it works okay.
Tje global height might be an issue though

Can I see your anti-sprin solution for the hub motor?

Hey more caster height = more rocker so go for it.

might need some tb110 to match though lmao

@Battery_Mooch premade spring contacts aren’t such a bad idea although I have ordered the BeCu sheet to mess around I went back and found these:

Have it here now actually

Is about 1.1mm of movement enough?

I think so, the travel of the spring in a pancake slip ring just accounts for the compression to get good contact and allow for any slop in the construction.

I really like how these will bottom out to prevent deformation.
One issue I see with the way the leiftech and SBX slip rings are assembled is you can easily press on the ring outside and therefore on the brushes underneath it

There is definitely some travel going on with the leiftech brushes. When I spin them in my hand while cleaning the grease I can feel it being slightly elliptical. This could offer some advantages for reliability I think. Right now I use about 1.2mm of compression, set at 4.2mm and the space is about 3mm.

This one would fit for trying to recreate a V2 brush setup with these premade spring contacts.
