Re: The Heavyweight (Hub Motor Build)

Personally I use Gurit 115 resin (it is incredible, miles better than any other I've used either wet or dry) but I hear good things about the 105 resin. If you are not experienced with composite layups, I would recommend you get a slower cure resin. This is both to give you more time to work the res...

Re: 10S custom skate ESC: testers wanted!

I think I will get the PCBs this week, so if I have time and it works well I will upload the new design by the end of the week. I definitely think it is worth waiting. I only run linux on my computers. There are surely other ways to build and upload the firmware, but I can't help with that. Once yo...

Re: Flux hollow core longboard (update!)

So to be one of those guys chiming in with their mileage: 5s, 10AH lipo gave me about 6km on my last ride with a 3.4v/cell cutoff. So that's about 4 miles? Unlike chaka I was cruising slower, at around 35km/h (about 25mph), and had a few starts stops. Also, if I gun it too soon my motor's don't seiz...

Re: 10S custom skate ESC: testers wanted!

With version 4.8 you can connect CSN to the same header and you don't have to modify the servo input. You could also connect CSN to one of the SWD pins and turn off SWD and use the pins as gpio .... For now you could run the server on e.g. a raspberry pi or some other small limux computer. Hey vedd...

Re: So I bought a lathe...and made Hub Motors

Urethane stayed on, and I didn't even had to use any epoxy. Yeah, I found it impossible to keep the thane on when sliding unless the wheels were only partially bored out. Even heavily glued it would jump up the aluminium lips and start pushing off. Are you running 6s as well? I find that casual rid...

Re: OpenSource Handheld Controller (E-go similar)

If you are printing it fine, you can try adding some resin (stuff used with fibreglass) over the printed parts. Just mix a bit up and brush it over, let it partly dry and do it again if you are worried. Works a charm, I just did this to my controller after watching the pieces bounce away from me as ...

Re: Looking For More Torque

The way I see it, you have 4 options, ranging in price/effectiveness: Get a second esc and motor running in diagonal. Reasonably expensive, reliable. Bump up the voltage with more batteries and a new esc, and adjust the gearing to suit the new voltage/speed you want. Reasonably expensive, reliable. ...

Re: how tight is your belt?

Single holes are much easier, but you need to adjust belt tension. No question about it. Have you considered using an idler gear? This can let you adjust belt tension but isn't as neat as slots are. Little bit chunky, but only requires one slotted hole to be cut. Alternatively you could get a machin...

I hear much better things about the LG cells than other cheaper cells used in these type packs, you should be fine.

Re: Power consumption?

I built a 63mm dual hub motor ride on the 90mm wheels, on a fast but cruisy commute this morning, making about 1300 watts max, I burn about 15watts/km. This is running on 5s. When I am going harder, it's more like 3-4kw peak, and burn in the low 20's per km. The max amps pulled can easily go over 10...

Re: Integrating Lipo Charger into E-Board

All above images will work, they are essentially the same. Two are identical, and one is charging through balance leads only. I would check the outer balance leads (true pos and neg) are able to handle the max charge amperage first. They take the bulk of the current, if not all at times. Alternative...

Re: How do you make hub motors?

Is it hard to make hub motors? They offer less resistance which is a bonus. Yep, they have much less resistance than geared drives. The slower the motor spins when kicking, the less resistance it can offer. As for the building, it's not too hard assuming you have the tools, knowledge and experience...

Yeah, does sound like you damages the motors somehow - did they burn out, hit anything or get a rock in them? Do you have a different motor you can test the esc on? Or try switching the esc on without a motor connected, and see what the LED mounted between the wires on one end does. Always better to...

Very nice, any chance you could upload the dimensions for the teeth mounting you used if they are accurate? Also, how hard was it to remove the end bell? I am trying to find the best way to modify one as manufacturers aren't being helpful.

Acrylic or Plexiglass is too brittle and it will snap/crack/break. Maybe, if you use Lexan or similar. This. Acrylic will form it just fine, but you will have it shatter on any impact. Other options is HIPS, ABS, or a nylon reinforced polymer. Ideally you want it to be a thermoplastic - heating and...

Re: ESC restarts itself?

The FVT can be tricky until set up right, check this thread and see if your issues fit any, and start by programming the esc to settings there? Each setup is different, but if the esc programs, then it's not toast.

I use a switch between the charge plug and the ESC, that will sort you out if you're worried.

The charge does not affect the relay because it is on the battery side, so no differ...
