Is anyone else going to be at the UK maker faire this weekend? I'll be at the Newcastle Makerspace stand with my board. I'm full of top tips on the dumb things i did that people making e-boards shouldn't do! It'd be nice to chat with some other e-board builders!

This looks cool! I'd like to do something similar as the ground clearance on my board is abysmal. What BMS are you thinking of using?

In the uk there is belting online who seem pretty good, cheap and they have a large stock: http://www.beltingonline.com/

Thanks for the info, that's helped me decide!

Hi Everyone! I've just finished my board and it's a hoot, I'm writing up a build log which i should stick up in the next few days. However i think i've got the gearing a bit wrong. As i live at the bottom of a pretty decent hill i designed the board for torque, with a 149kV motor, 10S with a...

Nice! I want to do something along these lines especially as i smashed the front end of my enclosure on a speed bump on my first ride out last night! speed bumps are not my friend :-/ My only concern is waterproofing, as if i can't ride when its a bit wet, i'm not going to be able to ride...

no, wait, i've just caught up with myself. You'd need a switch that could happily conduct 70 or so amps continuous while closed without getting hot, i'm not sure how many of those there are about. a quick search of toggle switches on RS doesn't look promising Anyway, i'll do some testing using...

This is the circuit i use as a switch to drive higher voltage loads from a microcontroller (arduino, pic etc). It's pretty tried and tested for pumps, fans and lights we use on the electric cars at work. I'm not sure if this would be suitable as a main switch for battery connection on an...

This is a really interesting idea. It'll provide a slight preload along that axis of the part which may prevent some failures. However 3d prints often fail along the join between layers (depending on the quality of your print and design) so this preload would be in the wrong direction. if you...

A waterproof enclosure is the way to go i suspect, and maybe some sort of motor cover. I'm thinking about this as i live in the north of england and it's a bit wet... I'm going to start with a nice sealable tupperware box and iterate on from there, as well as vacuum forming a motor cover...

That's a very familiar reaction! SHIT FIRE AAAAHHHH TURN IT OFF!!! That's an interesting motor mount, What is it?

Those battery enclosures are a thing of beauty! One of my friends in Newcastle makerspace has just build one of these, we were testing it last night, and it works amazingly! i'm planning on making motor and belt guards as well as a battery enclosure.

I'm up in Newcastle, there are more of us here than it seems! There shouldn't be too many problems swapping out the SLA batteries for an equivalent voltage lipo pack. A lot lighter! Resist the temptation to go for a higher voltage as you don't know if the control circuitry will take it, and it...

I work for a company that has made some pretty powerful electric vehicles, and we've done this extremely successfully, so it's a working, proven idea! One version used two motors, with different pulley sizes into a belt transmission, and on the other the front and rear axles had different...

I like that 3d printed battery box a lot! How waterproof is it?
