Hi John an' All;
What a heartewarming story! Thanks for the fone call, from the "Bar"!
Curious. How much does the guy Ted WEIGH? I'm sure lighter, than, say me,
Tim, or You?If he is a skinny guy, maybe that's why the front end really
lifted?I would think that the drivers weight would make a big differance, in
Zombies times? We COULD prove THAT point? Maybe I could make a pass
sometime? Hint Hint??Would Zombie wheelie with me aboard?I always figures
that I gave a locomotive a 40-50 lb extra pull, with MY tonnage aboard?Yeah!
Right, like that would make much differance with a 700 ton train<g>?The
other extreame here.So Ted made a 103, to your 106 so, there COULD figure
out a Power to weight ratio, and times for different weight pilots?Or how
much ya lose carrying passengers?IF you are alowed to in Racing?

The problem with a boost converter at low output current is the ripple.
Not so much of a problem when you're charging a battery, but becomes
very noisy when you're trying to do something like power an AM radio.

Hi,
Did I say "drove"? To be more accurate perhaps I should say "towed", and I
guess to be even more accurate it was actually the return lane we went down.
And wouldn't you know it, the only time Zombie gets passed at the track is
when I'm in control of how fast we are going.
I won't steal all of John's thunder, but my part of the story starts with
Otmar coming back to the pits with Ted West in the passenger seat of Otmar's
914. Zombie is at the other end of the track. So John, Rich, and I jumped
into my Jeep to bring Zombie back. When we get down there the smell is
pretty awful. John opens the trunk, and the smell gets worse... battery
carnage. Fortunately limited to only one battery.
So John is in Zombie, Rich is hanging out the tail gate of my Jeep, and I'm
driving. We're cruising at 10mph down the return lane and yes we got passed
by several gas cars.
This run did end Zombie's racing for the night, but it sure added some
excitement to the evening.
I had a great time participating in two action packed days of racing.
Thanks to all the NEDRA folks for putting this event together.
Regards,
Chris Brune

I don't understand. That's that first time in a long time, I said that.
I can get AM FM GM or any of XM clear as a bell in my EV or in my house when
my PFC-50B running wide open.
Maybe it's the high elevation or I keep the humidity above 50 percent at
all times.
It could be that all my home and building wiring is all industrial wiring,
which is all shield in steel conduit.
It also could be that I have several grounding planes, which I one grounding
rod for each panel, another one for the plumbing, another one for the
communications, and one ground cup connection in the concrete floor in the
shop/garage, that I use for for my experimentation in ground frequency
testing.
It could be that in my EV, I have a grounding type counter poise system that
loops around the car and all my control and comm wires are double shield
with only the outside shield ground at one end and the inner shields are
floating.
It could be that the motor, controller, batteries, battery charger and the
AC input power are all isolated from the frame and body of the car.
The only buzz I get is when I drive under very high voltage power lines
which are above 50KV.

just hit the delete key , and for those who have written and think " maybe
I won't post as ,,,,,, HIT THAt SEND KEY . Now I'm going off to work but
when I come home I want to hear all about it :-) ,

I've started buying stuff and was looking for advice on a controller. I will
proably be getting a 9" ADC motor (4001A maybe) and was wanting a cheap
controller (scarse cash) anyone got one in the US that will handle up to
120volts/500-600 amps max?
Nothing fancy, no regen or anything like that. Wish I had the
schematics/diagrams for the one in the middle of this page looks fairly easy
to construct
http://www.jstraubel.com/944EV/EVproject.htm
I've sent him an email asking if there were more details but didn't get a
response.
I'm not an electrical engineer and have only basic knowledge of electronics
but I believe I could construct one, wouldn't be as pretty but it'd work.
I've ordered some runman 2B battery regulator PCBs and instructions to
assemble as practice. I'll test them on a single battery with a regular
charger attached to make sure they work before hooking them up for real.
My project will probably take 6 months, probably a year to finish and will
probably make myself a veritable pest on this list, hehe. Planning on using
an S10 or similar sized truck (easier to put in battery boxes) for my first
attempt and have several leads on getting one. My brother works in machining
and will probably be able to machine any specialty parts I need (like the
adapter plate and hubs) so I can save a bit there. I will probably get a
PFC20 charger so it can be connected to the regulators, battery pack life is
a major concern, but I don't want to (can't, really, unless I want to take 2
years paying) pay retail for a controller or DC/DC
It doesn't have to have a lot of range, planning on using it for commutes to
work which is less than 5 miles each way, max 40mph. But it needs to be
simple in construction and easy to work on in case something barfs on me.
Abjective:
Obtain/build an electric vehicle that can be used for short, daily commutes
to work that is very dependable and has long battery life.
Plan:
1 Will get a good charger and regulators to take care of batteries (onboard
probably). I saw the post about trainning new batteries, short (~2 mile)
trips and topping off after each one to train them (20 6volt batterys).
2 Will get a used (if possible) ~9" motor (probably ADC)
3 Wanting to build own controller and DC/DC (if possible, buy used, low
powered if not possible).
4 Going to use a small pickup as the glider to simplify conversion (and I am
a -ahem- large person, don't think I could fit in a small car, weight and
volume wise)
I welcome any constructive advice but will ignore people that just call me
an idiot without giving me an alternative that works with my plan above.

Its good thatyou have the "grin " back Seppo. My own Citroen Berlingo
(same
as partner) is also off the road for a couple of months now since the
controller board went bang. I am still trying to get a replacement at a
sensible cost.
It would be interesting to hear the process you went through to change the
motor. Me and another Berlingo owner in the UK are writing up various
procedures for changing out parts in these ev's so that we can post a
guide
on the web for other owners. We have already done, battery packs,
controller
and heater instructions and it would be nice to add some help for motor
removal.

Hi,
I thought I'd do a short post about the method I have been using to capture
Zilla data from Zombie, and also last night from Otmar's 914.
In the past John has been putting his Mac laptop in the passenger seat and
capturing data using a program called Zterm. There are a number of
logistical issues with this. The laptop battery can't handle a full night
of racing. I personally worry about submitting the laptop to the vibration
and G's associated with going down the drag strip. And the bottom line is
the laptop is a bit bulky to have in the car with you.
My thought was let's figure out a way to get my Palm V to do this job. So
my solution involves the following programs:
ptelnet - this is the Palm terminal emulator that Otmar recommends for use
with the Zilla. It is very handy for interacting with the Zilla, but does
not have the ability to capture large data files.
AccessIt! - This is a different terminal emulator for the Palm. It is not
as good at interacting with the Zilla, but it does generate great log files.
These log files are stored as pdb (Palm database) files on the Palm. Each
log file is conveniently time and date stamped.
Weasel Reader - Weasel is a program that is intended for viewing pdb files.
It has the added feature of being able to beam these files as well. This
program is used to beam the logfile generated by AccessIt! to a PC.
Wordpad - Windows text editor. I use this program to edit out unwanted info
in the logfile.
FasTrack - This is the PC based program that SEVO (www.suncoast.net) put
together for graphing Zilla data. Thanks!
The process goes like this:
1. First setup the Zilla to start sending data. I do this using ptelnet on
the Palm. This is done from the "p" menu using command "Q4" (make sure "Q"
is upper case).
2. Now start AccessIt!. When you are ready to start logging data click
"OnLine". This will start logging the data to a file. The fun part begins
here, go drive/race your EV. When you are done click "OffLine" to close the
log file.
3. The next thing we need to do is send the data to a PC. There are other
ways to do this, but I wanted to do this via IR. My laptop has an IR port
and so does the Palm V. So I go into Weasel, select the log file I want to
send (filename starts "AccessLog-....). Then from the menu select Beam
Book. The PC then picks up the file and stores it (in my case it shows up
on the desktop).
4. I then use Wordpad to edit and view the file. There is some garbage at
the begging of the file I delete out. In drag racing there is a fair amount
of unwanted data so I can edit that out as well.
5. Then you can open the file in FasTrack.
FasTrack is a great tool for quickly analyzing data from the Zilla. There
are a couple of suggestions I have for making it more useful.
First, everytime a "trace" is turned on and off it resets the x-axis
scaling. This is fairly annoying if you are trying to analyze a specific
portion of the data.
Second, the Zilla is spitting out some data that isn't shown in FasTrack.
Specifically which mode the controller is in. Zombie is constantly dancing
with different Zilla limits (battery voltage, battery current, motor
current). It would be helpful if there were some way to graphically show
which mode the Zilla is in.
John and I hope to put some snapshots of Zombie runs on his web site pretty
soon, so be looking for this.
We also captured Otmar's run where he blew an Orbital last night. Happened
just after the end of the run. Current draw from the Orbitals was about
1250 amps at the end of the run.
Regards,
Chris Brune

1.
does anyone on the list have connections at apple or dell?
I would love to take those recalled li ion laptop batts off their
hands
2.
does anyone use marine-style battery connectors? Someone mentioned
that anderson connectors can short due to salt buildup;
i imagine the hookups for sailboats in dock might provide more
protection? i live on the med sea so i'll have plenty of salt in the
atmosphere...

The shutter I was talking about is a piece of film with gradual
clear-to black transition through all shades of gray
on the way. It is trivial to make such a shutter - I use
to do it when photographed a sheet of paper bent such
that bright side pointed toward light source (like sun)
gradually turns to the shadow on the other side. The
developed negative cut out was the shutter ready for use.
You can make such shutter from a sunglasses with
almost clear bottom and dense dark top coating.
But clear-to dark ratio won't be too high.
But, really, while it is all fun, it's a school-hobby approach.
One can make it work, but if you want to "install
and forget" sensor, use the one meant for the job.
A TPS is the part. I use Bosch throttle pot. If connected
as prescribed, no one have heard of a failure of one.
People who got Siemens system can tell they have real thing.
It's been suggested many times here, and only desire to
get as good solution but 10x cheaper keeps
generating bizzar solutions for non-existing problem.
If one find $30 part, he won't get it because he think he may
built the equivalent for $8 parts worth. So far so good.
Once this part fails on a freeway, he'd be in the situation
where you'd gladly pay on the spot twice $30 if he only
could avoid getting the trouble. Very the same "unconvenceable"
person. At this tome he likely will regret that he didn't
install the right $30 part in a first place.
But in a first
place there is no way you convince to spend $30
for non-tangeable peace of mind. Sort of buying insurance.
People is people,
you know. So, have fun with photo-sensor throttle pot,
best luck! (it's not directed to you Lee, just thinking
out loud).
