An easy way to save a good amount of budget to the board would be to skip using an VESC all together and just go with an ESC. Even cheaper would be to buy someone’s used ESC and use that as they tend to be sold for very cheap.
My current ESC I got used with the remote for only $20 after a tiny drop of water killed my old ESC. It was an old Meppo esc and the remote was dying but even after the remote fully died a working replacement on Amazon was only $27. Only downside to ESCs is that you can’t use a ton of current for your motor and you can’t program them at all.
I have heard of one dude putting stock 10S electronics from a cheap prebuilt onto a SBX and it worked fine supposedly. So unprogrammable ESC seem to be ok with slip rings. Only thing to watch out for is getting the right hub motor or outrunner for whatever esc.
One last note about non-VESC controllers is they will put out enough power and be not overkill for a 5055 motor like any v6 vesc is.
@rusins do you have spare parts or know of any nearby? seems like 50xx motor,esc,batt,remote are required.
As far as I know, most of the ESCs would get fried from too much current well before any motor would. Kind of hard to know for sure though since even ESCs that are labeled with their exact part number don’t list how much current they can handle and looking the part up online gives no specifics either.
Looking at your OG drawing it makes sense to me the highest refined design for manufacturing would be PCB slip rings like the SBX directly coupled to a PCB battery and a ESC all one module. Minimal wiring to make it super compact.
Issue with that design is do you try making the Caster module low enough to fit below the battery pack all below the deck or do you split the battery to either side so the caster sits up against the bottom of the deck like the SBX.
I guess actually you could have a PCB battery pack with a hole in the middle or a C shape.
I was thinking alot about the slipring and I think this variant would be the most durable and easy to make. I dont want to use pcb sliprings(pancake sliprings) because It would need much precision and to me it would be a bit too expensive.
Batteries would be on the bottom splitted in two segments
Electronics such as vesc and other would be stored in the upper tank
The cables of the batteries would go through drilled holes in the deck.
I’m probably going to buy used esc because why not
Is it worth buying prebuilt batteries? or build them myself using 18650 batteries?
If I build batteries myself do they need some type of protection?
And what is the difference in esc 75V 80A continous and 75V 80A peak?
the lowest height you can make the design with minimal deck mods is the diameter of the caster wheel.
Side note if you want to try two castors on the nose and tail of the popsicle deck you could drop it lower.
Edge wheels in the middle of the deck like the @Mistreetsurf would be worth a test in general.
I was thinking to 3d print or plastic mold a wheel shape and then wrap it with 2-3 layers of inner bike tube. and glue them together with silicone. Although i dont know if i will be able to get this small size innerbike tube.
Hey nice to see some new interest in a diy e snow board freebord, 3d printed parts work for proto typing…myne has lasted now for 3 months riding every second day without breaking, but I know if I try and jump on it, it will break. That said I’m not too sure what the solution is, I rekon aluminum welded parts or channel for the casters. Hope this helps you, still is good to make something yourself don’t give up. The other option is to try…and get a set of freebord casters and mod them to make it work, at least you know it will last:+1:

Thanks jon, i really appreciate your comment. Yeah im thinking to firstly 3d print it, then when design will be polished, i will convert it into metal.
Sadly currently i literally dont have any money i can hardly afford food, as i am in a really bad financial situation. So no building this year :). Thinking about starting to build next year’s summer, spring.
I know how that feels believe me, but the first time you slide or spin the board you have made…you will know it is worth your effort, …I say again…don’t give up, If you need help let me know, I also had to build cheap…but so what👍
