Yip, I've been clicking away. Not so many the last two days, been very busy here. Same goes for blog. Getting facebook under control has been a chalenge, but worth it! Of course the originals are much higher res.
> Nuna5 looks flash!
Sure does, sunswift (Bat-Sunswift) is very nuna-esk, but was actually designed before nuna published their design. I like sunswift's styling better, with the whole batman thing going on with the trailing edge. Nice car!

Guess who crashed today! They lost it on the corner going on to the straight, but got it fixed after a few hours.
> Lots of brakes with (factory designed?) pull-back springs!
Yes!
> Interesting wheel failure (red cast ally one)
Shipping :(
> NTU / NGM motor stator details - looks easy to make!
Yes! You might also notice the other stator laminations, punched out BEFORE it is wound up with some cunning software on the winding/punching machine.

It's a water pump, axial motor, with sensorless sinewave drive, very cunning because all three windings are energised all the time, no open phase to measure back EMF. Instead the look at the current waveform, and simulate the motor to estimate the rotor position.

Esteban! I'll blog some more about them.
> How is "your" team doing - are you ready to race?
> Has the motor controller stopped throwing "Tanti(lums)"?
No more tanty's. I spent hours fixing the other controller which blew the fets, fet protection zenors, gate drives etc. It was a real bitch assembly wise. photos
We got solar max tyres from sunswift, amazing difference, I'll blog that one. I'm now a key team member, working on the car to all hours, solving all their technical issues. It's quite fun really. I'm not just a tourist, I'm really racing this time around, Towards Tomorrow is almost mine!
> Looks like a lot of fun - wish I was there!
Sure is!
