Re: [PIC] example code for PICDEM2+

Yes I have the samples working. And I have an
uC-OS II samples as well but it is not really of
much use.

I want to see some more examples and interesting
hacks though. C-based examples will be preferred.

Regards,
Xiaofan

Re: [EE] VFD for 1 phase AC motor

I lived in Southern California during 2002 to 2003 and I saw some small
EVs insider University of California Irvine and some outside GM' Torrence
Advanced Research Center. I had been to the two Fry's near to Irvine but I
did not remember there was a charging station. I did hear that Southern
Califronia Edison had a plan to set up charging station along the Pacific
Coast Highway or some other places but I think the plan was scarpped.

I think now the direction is more on the hybrid type. The battery powered
EV is not so easy now. The only remote chance is that the oil price continue
to rise (at least US$120 per barrel) and then maybe this type of EV got a
chance. Fuel Cell may come to rescue of battery powered EVs but I think
it is still far away from commercially viable.

Xiaofan

Re: [OT] Who controls the internet

Interesting discussions. Is this thread inspired from BBC's now
running "Who runs your world" series?

Who controls the Internet? I guess no one can control the Internet
and it is good to kee p it this way. Still take note Internet does not
contain really all networks around the word. There are still a lot
of special networks around.

Xiaofan

Ah.  Poor memories.  The rest of the world wasn't very enthusiastic to
participate an "american controlled" set of protocols in the first 
place,
resulting in the mutually incompatible ISO protocol stack (at great cost
to everyone involved, including the US, since they couldn't ignore an
international standard even if they had their own protocols.)

Cynically speaking, the ISO stack failed, and now the "rest of the 
world"
wants an opportunity to screw up the american stack.

On the other hand, perhaps I should look more carefully at what sort of
"control" we're talking about here.  Administrative control?  Control
of the protocols (it's not like there hasn't been a lot of international
participation in IETF already, for instance)?  Getting even more 
cynical,
I think perhaps anyone who believes that "the internet" is controlled by
the US government... just isn't paying very much attention!

Re: [EE]: High voltage converter?

A simple 12V to 6V isolated supply can be done easily done
by a push-pull converter. Since it is low power, a simple
ring core based transformer can do it. There is no need to
regulate it. A simple linear post regulator can regulate the voltage
in the secondary side.

Re: [EE] VFD for 1 phase AC motor

There used to be charging stations by the "Alternative Fuel Vehicles Parking
Only" spots at the Sunnyvale, CA Fry's, but I don't think they're there
anymore, either.

If you have a cheap source that will do things like rewind the pump
magnet (!), perhaps you should just investigate what it would take
to implement a DC-based pump (either along the same lines as a DC
buzzer, or using a motor to drive a cylinder or diaphragm.  I have
such a motor driven pump surplus from Electronics Goldmine - it just
uses a rotating cam on the motor to drive a the diaphragm.)

Yikes!  This is waaaaaay to long.  I can't imagine what they are doing
during all that time.  I don't remember exactly how long the EasyProg takes
to do a full 16F88, but 20-30 seconds sounds about right.  I'm not at the
office where I can try that right now.
