I did not find the fault with the sensorless boards i............ <review of sensorless boards>

Can someone please do whatever magic is required to make this video small and nice?
I just cut it down to size and left it in a high quality format. It is about 16M

When the wife comes home for lunch I am going to get her to take a movie of me doing my (now infamous on my street) 0 - 30MPH burnout
The on board vid had so much wind noise that it was pointless.

methods said:Hi Geoff,
Whatever size you think is appropriate.
In the past people have complained about my WMV format and large size.
I am sorry, no pictures of the bike as it is a somewhat shameful Walmart bike.
Thanks,

Are the phase wires the stock 16g?methods said:The phase wires were so hot after I did this that I burnt my hand
julesa said:AWESOME Patrick! That first video really shows off the bike's excellent cornering characteristics.

You should do more of those burnouts
Methods said:Geoff was kind enough to fix the video up.
He did a good job. i will upload it to my server a little latter.
I also have some more pron pictures.... Something showed up in the mail
So I am going to start an open debate in a few posts here...
I need you guys to put away your extremest hats and put on your "normal" hats.
We are going to debate how to configure the controller
* Phase wire length
* Power wire length
* Wire gauge
* Connectors for phase and power
* Conventions
* Compatibility
* Sticking to Crystalyte connectors
* Cost vs. reliability vs. ease of use
* Which wires to bring out (Cruise control, brakes, regen, external power switch, etc)
* Keeping it simple (like ebikes.ca)
We need to talk about all the tradeoffs.
Features vs. reliability
Overkill vs. "enough"
Wants vs. needs
This is your chance to literally build the controllers how you want them... but ....
DONT be too fast to spew out every feature you ever wanted because you would be surprised at just how much it can increase the cost
Every connector we add decreases reliablity, increases parts cost, increases congestion inside, increases build time... Just adding one cable could add $10 to the price of the controller.
I really like Justin's idea of keeping it simple.
I also like the idea of bringing out one master connector that has all the bells and whistles in it that most people wont use
anyhow. . .
Start thinking about that.

swbluto said:Some kind of indicator would be nice, for errors and stuff. Audio indicators would be nice so that a person can get an idea what's going on while riding. I just purchased a few SMD mylar speakers, and the can-be-loud kind only cost something like $2 and less.
Also, having the ability for the end user to add on a sensor (as simple as one extra plated through-hole in the pcb) and being to tell the controller what to do if the sensor goes below or above a programmed value(as simple as updating the programmable software) would be helpful. Example, if the voltage level goes above 4.5 volts from a 5 volt temperature sensor corresponding to 300 degrees fahrenheit, the user could select a) pull down the throttle line b) sound the audio indicator with a specific choosable audio pattern c) whatever else seems like a reasonable response sequence. Then the user could add temperature protection to the controller or motor or whatever, really if they feel like they might risk burning out something(Such as for the power freaks). And, it's just that, one extra through hole and the requisite programming. There'd really be no extra pcb costs since it's just one more hole, and this presumes the user buys the sensor and installs it themselves. Of course, there should be support documentation of some sort, which I'm sure people would be happy to write up on the forums. Also, it'd be cool if there was some "open source" playground for programmable software features so people could make the controller more feature rich if they wanted to on their side, but that'd take some development which it seems doubtful keywin or whomever would invest in.
Edit: Well, if methods doesn't want this message to be responded to and that's why he didn't keep it on here, and that's why my post might seem a little tangential, then don't respond to the following copy I made. This is just for justifying my post's raison d'etre, that I so don't want to delete as I put hard work into it!

swbluto said:Anyways, I was just looking up digikey for those incredible specs and I noticed it has pretty decent A/D resolution and quite a few A/D ports and it's nearly as cheap as the 8-bit atmega168 AVR's that I currently program! When you say micro-amps, do you mean during sleep mode or during actual operation?
