Please please please fix those photo BBs, really keen to check yours out! Yeah I've just been using Solidworks cause it's what my uni provides for us. I haven't had any experience with other packages, but as a piece of software its VERY rough around the edges. I'm pretty keen to try out some...

howzit ek se! Yeah I checked them out before I ordered a while back and they look a bit suspect. Also, the stuff in their kits isn't entirely what we need :/ so would most likely have to get them to bring it in, but it would probably be quicker (and cheaper) to bring it in yourself. It's been a...

In terms of wire gauge, I think I calculated about 8 AWG a while back to be super safe, so yeah I guess I'll have to make provision for that mechanically. Yeah I'd be charging it like that, but the max charging rate is theoretically 2C. As they are in parallel, if I do 1C, I can theoretically...

Same. I don't know why you say it's prohibitive. You probably can't build a board with those base specs for less than $500 (on a DIY scale in any case). Markup of 200% is pretty reasonable I'd say for a product like this. I'm sure they've spent a lot of dev time and cash, and I'm sure people...

Cells under the board would be pretty useless lol. Unless you develop a new type of sun that shines out of the road. I think that it could work. I thought about incorporating this and/or piezo transducers in the board. It's not going to charge the board in any practical amount of time, but...

Would like a bit of comments/criticism on my idea for battery connections. From what I've read the safest and best (in terms of longevity) way to charge LiPos is in parallel. In my case, I'm making my own "custom" battery setup using single cells. I need 8s, so I will use 8 cells in series. I...

Thanks for the comments. I've been using Solidworks for about 3 years, but mostly on and off for Uni assignments. Every time an idea props into my head I like to model it to see what it looks like so I've become pretty good. Regarding the putting the batteries where I intend to okp, why would...

Update time. Ok so I've ended up going with HTD 5, 9mm belt in the end. Everything else was either too expensive or not strong enough to be durable. Ordered two of them from SDP, waiting on those. Also, I've settled on an RR of 2.5:1. This should get me crazy torque with the two motors and 8s...

This is entirely stupid and impracticable. 2015 my ass. Does it come with a 10 m copper roadway so you can ride around your garden for an hour until you get bored? We're stuck with wheels for a while I'm afraid. At least until a cheap, small, light energy storage solution comes around.

the. most. awesome.

Sweet! Just a thought. And I'm glad it's not worth the bother :roll:

No, in principle I very much disagree. Think about what's physically happening. Take it to the extreme and say (with a dual diagonal) that your rear motor is reversing and your front motor is going forward. Your board is going to rotate. Maybe not very quickly, but it will rotate. You have a...

Was doing some thinking.. For dual/quad motored boards, being able to provide an "augmented" steering effect by (slightly) slowing down the inside drive/speeding up the outside drive when toggling the nunchuck left or right could be interesting. I know that I'm not going to be able to do this...

you should just scale your RR based on the top speed to keep torque and speed characteristics the same. so work out your speed with your current RR and wheel diameter (Vt=w_motormax*RR*r_wheel) and work back to get your new RR based on new wheel diameter (RR=Vt/(w_motormax*r_newwheel). Either...

steps: - find the link to Austin's code on github in the nunchuck thread - download the code - have your uno + usb at hand - follow one of these guides until you have downloaded the arduino IDE, have your uno talking to your PC and made sure that you can upload code to it - open austin's...
