Sorry - forgot it was Thanksgiving down there. Get it done when you can - you need to spend time with your family!

I made a bunch of changes and reorganized things, like grouping some variables into structs. Just got a chance to start debugging tonight. Fixing stupid things relating to the datastream. I should really be ready to send it over tomorrow.

I think they really know what they are doing. Here are their blogs:

OK it was called 4shared. Here is the schematic that they put together:

That's very cool. It's actually pretty close to the one I made for the PC board design I posted a bit back. I had to change things to better understand what was actually going on. The main differences that I can see is the 6011 ucontroller, more I/O options, and 4 PWM output pairs set up for smaller switches. It's definitely a helpful double check.

I tested the iphone 4S yesterday with google hangouts live. You have to acknowledge a *BUNCH* of warnings before you start it up, but it works. I'll be using it today to video one set of meters.

And I'll be posting the logs as usual, so you can see the setup and confirm I didn't mess anything up .. or that I DID mess it up .... and how many tries it takes me to type the commands without typos ..

Wow, that single sided hoist looks crazy.
Sort of like working under a car when it is lifted up by a forklift.



They don't appear concerned but the bend on those forks and the resulting lean of the car just looks wrong.
Maybe if i was just lifting a car to swap some tyres but not to get underneath.
Or is this just normal and i am being to precious?

[MPaulHolmes]

Maybe I should add a line or 2 in the code so that, when the car stops going forward, the regen is disabled, so the car won't fly into reverse at a stop light?

LOL! It's all good - that guy in back is holding it up.

You know, my grandpa is swedish,and he told me that our family changed their name from Svensson (or ssen or I don't know) to Holmes to sound more american, because people thought swedes were dumb. I need to send him their link, to help break the stereotype! Well, first I have to show him how to use the internet. haha.

ha, I heard the same story, only it was the swedish army what said "we have too many sveningsons, this is your new name".
