Thanks for the information on the dial indicator. The lathe that I have
been using is at my place of employment. It is old, but seems to work
well. I will find out the make, and let you know, if you would like.

Brian,
You have a lathe, but don't know what a dial indicator is?
Here's one:
http://littlemachineshop.com/products/product_view.php?ProductID=1236
You mount it on a little arm attached to your lathe (or whatever
spins), and put the tip on the outer edge of the spinning part, and
watch the needle for movement. It's very sensitive. Each mark is 1
mil. There's also something called a "dial test indicator", which is
similar, but better for inner diameters.
What kind of lathe do you have? Are you happy w/ it? I'm kinda
looking at getting one.

I have my fare share of flat tires being in the lawn business , after
wearing out a few of these little compressors I got 2 ends ( the part that
goes on the tire valve ) form some old flat fix cans and a long piece of
hose the same size . Now I just hook one end to the flat and the other to
one of my well inflated truck tires . No wires to hook up, fills up in less
that a minute , takes up little space , and is still working .

Alan,
I have found that a very slow acceleration doesn't
really improve the MPG on my 04 Prius. Remember, the
battery pack is being recharged by the ICE and this
process is lossy. So, everytime you use the pack
energy, you are wasting a lot more when the ICE tries
to recharge it later. I generally start off the line
on electric only, but accelerate moderately at speed
above 5 MPH so that the ICE kicks in. I am getting 55
MPG on my Prius.
You get better MPG if you keep a moderate
acceleration. This way only the ICE is being used to
accelerate. Also, an ICE is most efficient if it is
heavily loaded.
Of course, there are times you do not want the ICE to
run. For example, if you know that the last 1/2 mile
if your drive is all flat, is in residential
neigborhood, or in parking lot. Under these
situations, the ICE would not been efficient. I
sometimes have to push the EV mode button I installed
to force the ICE to shut off under these situations.

April shows the Tzero & for Christmas we have the Honda Kiwami. The Kiwami
utilizes a fuel cell that powers a DC motor. It looks like a stretch Civic.
The $1.50 charge in part benefits chairity. Interesting a parts chain would

Considering you have to step through electric scooters, bikes, and
choppers to walk into Checker any more, maybe not a big surprise they
are highlighting electrics.
Let's hope Honda's next electric looks more like the Kiwami and less
like the EV+!

If I remember right, a typical consumption level is about 500Wh/mile?
It is typical for a large bus. A normal car (maintained tires, not
dragging brakes, etc)
would do ~200 Wh/mi. Really depends on how you drive and your terrain.

I did receive it too - the first time I sewe temp compensation
requirements. But, we will question
TS about validity of this data, especially suggested charging at above
4.5V (if I remember) at cold temps.

Hi All,
Does anyone know what a line stabilizer is?
PN ATV2000 though Marlin P. Jones + Assoc surplus,
page 7 in their new catalog, doesn't say what brand.
Discribed as a benchtop autoregulater for ac to
compensate for low line voltages. One says it switches
windings to regulate.
Does it have a transformer or autotrandformer?
I was thinking about using it as a battery charger
with mods.
Another question is on pg 15, they discribe
transformer outputs with corrections based on the
filter type, inductance or cap type.
Full wave Centertap into choke filter = .7x the
transformer secondary amps
FW CT cap input =1.2 Trans Sec amps
FW Bridge into choke = to required sec amps
FW bridge into cap =1.8x sec amps
So which way is it for the most power out, eff
for a given transformer?
Exactly what is a cap or choke input and how do
you get the most from the trans -filter combo? Just a
choke in series or a cap in parallel?
Thanks,
jerry dycus

**************
We need your help.....
H.R. 6 SEC. 41011 Alternative Motor Vehicle Credit
To enhance energy conservation and research and development, to provide for
security and diversity in the energy supply for the American people, and
for other purposes.
*******************************************************************
Sec. 30B allows a $4000 tax credit for fuel cell motor vehicle.
Recommendation
Sec. 30B be revised to include not only fuel cell motor vehicles but all
Battery Electric Vehicles (BEVs). This recommendation includes new and
converted motor vehicles.
*********************************************************************
************** Send Above ************
Background
Fuel cell vehicles are promoted because they (1) do not use imported oil
and (2) are Zero Emission vehicles (ZEVs). Battery Electric Vehicles
(BEVs) similarly use no imported oil and are also ZEVs.
Since the Energy Policy Act of 1992 the automobile manufacturers had the
advantage of a tax credit for BEVs. The manufacturers built a few
prototypes and production vehicles for lease. But these BEVs have since
been removed from the marketplace. General Motors actually crushed the
EV1 that many people wanted to continue to lease. Why? The automobile
manufacturers realize that BEVs are not in their best interest
because their commitment is to the internal combustion engine which
requires continual service (tune-ups, oil changes, exhaust system repairs,
and more). Now the manufacturers are trying to change the emphasis to Fuel
Cell Vehicles that are decades away from production!
Congress passed the Energy Policy Act of 1992 to decrease the use of
imported oil. Meanwhile, our use of imported oil has increased. We have
lost 12 years! Therefore, it is the time to allow the tax credits for
converted BEVs. Congress has the opportunity to revise the regulations to
make alternative fueled vehicles, and specifically BEVs, a reality.
Benefits
BEVs , including conversions, can be built by small manufacturers or by
individuals. Where Fuel Cell vehicles are more than a decade away, many
people can and do use a BEVs now. There are approximately 5000 BEVs
currently on the road; The potential is 1 million BEVs within 10
years. By reducing the cost of new and converted BEVs, the benefits will be:
1. The demand for imported oil is reduced in accordance with the goals of
the Energy Policy Act. This is priority No.1 !
2. It increases the demand for new technology. With the potential for 1
million BEVs, new technology (e.g. batteries, motors, etc.) will be
developed, demand will increase, costs will decrease. The U.S. will take a
leadership role in technology.
3. Emissions from mobile sources in urban areas will be reduced. Over a 5
year life, approximately 25,000 lbs of emissions will be eliminated. That
is 6 lbs of emissions for every federal dollar!
The Clean Air Act allows the conversion of existing vehicles. The
"recycling" of an existing internal combustion engine (ICE) vehicle to BEV
eliminates the emissions. Yes, eliminates! "Recycling" of existing
vehicles is not only common sense but good economics.
Our recommendation will do just that. BEVs will not only decrease our
demand for imported oil; they will also decrease mobile emissions!
Therefore, we ask you to:
1. Email your U.S. Representative and U.S. Senator. Ask them to promote
and vote for our recommendation. You can send the top portion of this email.
www.congress.org to obtain email addresses of your elected officials
2. Please call Sponsor of H.R 6 : Representative J. Dennis Hastert (R ?IL
14th)
Staff Energy - Chris Sarley Telephone No. (202) 225-2976
3. Email President George Bush at [EMAIL PROTECTED]
4. Email Organizations (American Lung Association, Solar Energy
Association, etc.) and ask them to lobby for this change.
5. Forward this email to other EV hobbyists, clubs, and organizations.

SUNDAE DRIVE
New hybrids are more powerful and sexy, if less efficient
The next crop of hybrid vehicles is eagerly anticipated not only by
energy-conscious geeks and early-adopter hipsters, but by regular ol'
Americans who like to have their apple pie and eat it too.
Auto-industry flacks are predicting buyer excitement over
soon-to-debut vehicles like the hydrid Honda Accord and Lexus RX SUV
-- long on horsepower and sex appeal, short on gas consumption
(though slightly less short than their predecessors). "It will be
like enjoying a hot-fudge sundae, without the calories or the guilt,"
says Toyota's Don Esmond of his company's forthcoming Highlander SUV.
Psychologist Margaret Krikorian of auto consultant Iceology also sees
the new hybrids appealing to Americans' have-it-all sensibilities:
"These cars speak to our emotions and rationalizations. It's like
being smart and beautiful."

Recently when AustinEV was at the Renewable Energy Roundup
(theroundup.org), we were exhibiting our cars next to this fellow,
developing a similar idea:
http://www.tritrack.net/index2.html
Say what you might about the aesthetic merits, from speaking to him it
seemed like he's done his homework, from my layman's perspective anyway.
Last I heard he was supposed to have some trial installation in the works
in a small town in Texas. Haven't caught much news about it since then.

Anyone have a starting point recommendation on the number of amp-hours
to set my E-Meter for my 180VDC Optima YT group 31 pack?
I started with 45ahrs, but I think I have a little more capacity than
that, since the meter reaches zero and the pack is still pretty stiff
under load. (I haven't driven to "dead" yet, and I'd like to avoid
doing so just to determine the max capacity)
I'm still tinkering but my emeter shows .1amps going into the pack even
with no loads connected. Interestingly disconnecting the Emeter from
the shunt (using a connector in the shunt wiring) causes the emeter to
read +.6 amps. This makes me suspect that that connector may be part of
the problem. Except for the connector all of the shunt wiring is good
quality twisted pair (stranded cat-5e) Is there anything else that
could cause this misread (noise from the DC/DC?)

Sam, There are numerous ways out there to join an electric motor to the
vehicle drive line that allow for up to several thousandths of mis
alignments without causing vibrations. Go to any good Bearing shop and
ask them about it.

Subject: Alignment, vibration, U-joints, etc.
Was reading about some people who had problems with flywheel vibration
after
machining an adapter plate, blah blah. Seems this is a common.
I've thought about this problem often - of trying to align an electric
motor
with a transmission perfectly, of machining adapter plates and what not,
etc.
Seems that this part of EVing (if not other parts as well) is a fairly
difficult excercise in doing it just right, plus you need expensive
tools, machining
expertise, dial indicators, etc. In fact, it's a part of EVing I'd just
as
soon avoid, if that is possible.
Would doing away with the transmission solve some of these problems
(aligning, vibration, machining adapter plates), or would it create new
ones? If you
do away with the transmission, I presume you attach the motor to the
rear end
with a drive shaft (assuming RWD)? If this is the case, am I correct in
presuming you could have a u-joint to couple the motor to the drive
shaft? If so,
would this allieviate the need to have some sort of ultra-precise
alignment
between the motor and the driveshaft and/or rear end? Now, would this
also tend
to get rid of vibration problems, or would non-straight alignment tend
to
create vibration problems? Where would vibration problems stem from at
this
juncture - the driveshaft?
To ask a really stupid newbie question, is the "purpose" of a u-joint to
make
it so that you can attach rotating things at different angles (so to
speak),
therefore eliminating the need for straight alignment?
I'd really like to know this stuff.
Thanks.

Mark the group 31s where 90 amphours ... Right?? it's on the sticker... Just
read it ....right????
The regulare Yts Group 24 are 55 amphours down from 65 when they first
released them.
80 might be what they are now.
Disconnecting the E-meter, from it's analog ground pin(shunt Neg) While it's
powered up,and the big voltage is still on..... Boy you are a Brave
Fellow!!!
Muy Bad compadre!!
Yea spanking that 100 Mv rail to rail Opamp, just might be part of the
problem.
Got 'em equalized in yet???? all 14.8 volts while feeding thim less than 2
amps????
If so, reset the meter, to amphours go for ride.... when battery stack sags
to less than 180 volts with 50 amps load. Park, record AmpHrs, recharge.
And I don't mean then drive home....I mean recharge where it sits!

All I'm really looking for is string or some other material
with good flexibility, strength, and heat resistance that
can be used to pull brushes away from the com bars.
I'm trying to build a mechanism that will pull the 8 brushes
in an e-tek off the com, which is made "easier" with them all
facing the same direction. I've attached a small piece of
copper wire to the brush wires where they are attached to the
brushes. The new piece fits within the brush spring and is
accessable when assymbled by compressing the spring by pulling
the brush wire up. At this point it is simple to thread some
NON-CONDUCTIVE string through the new wire attached to the brush.
For the moment I used a yoyo string (yup a yoyo) threaded
through a single piece of round arts and crafts wood plywood.
Pull the plywood piece and all thr brushes come off the com.
Though the 8 springs combined pose quite a bit of "resistance".
It might work better to use individule actuators or somesuch.
Anyway...
Got any ideas of what to use for the "strings"?
.oO( Or any good ideas for making this work )

Cool looking EV but 2 things jump out. First is
it's CG is probably too high for a 3wheeler.
Next is it's too long and wide for a single or
tandam seater. But still not bad compared to our poor
choices available from Detroit.
A GM Lean Machine style tilting 3 wheeler would be
cheaper, lighter, shorter and narrower and as low
drag. You could park 2 LM vs his trike in the same
space and drive 2 abreast on the highway reducing road
overcrowding.

Last I heard he was supposed to have some trial installation in the works
in a small town in Texas. Haven't caught much news about it since then.

Hi Everyone,
If you are doing a conversion, keep your eyes out for funding
opportunities. I just got confirmation today that my project was
accepted for $1000 of funding through an honors society research
opportunity on the Utah State University campus. With costs totally
more than $7000 on the 200sx conversion, this doesn't seem that
significant, but it means *alot* to a poor married college student with
1.5 kids :) The $2500 Utah tax credit for an alternative energy vehicle
will be nice too.
I'm hoping in the future to set up www.evgrin.org to help with funding
opportunities. Maybe list state and federal tax credit opportunities,
etc, etc. I'd really like to set up somewhat of a scholarship type fund
and get some backing from those that have money to burn. Don't hold
me to any of this - just nice thoughts that I hope materialize in the
next few years.

Was reading about some people who had problems with flywheel vibration
after
machining an adapter plate, blah blah. Seems this is a common.
This is not a common problem. We've sold hundreds of adaptors, and I can't
recall ever having vibration as an issue. If you want to avoid the hassle
and expense of tooling, and don't feel your machining and other skills are
up to the job, buy a professionally made adaptor. It doesn't take a lot of
expensive tooling or great skill to simply install it, just some patience
and care. And we have installed adaptors on motors for some customers who
requested this.

I really like the idea of such a program. It would provide
incentive for more of the younger generation to build EVs.
It's not easy gathering the > $10k I'll need to do my
conversion, so anything I can come across would help.
I'm rather shy about accepting grants myself, though. I want
this to be my car, built entirely by myself, and my own
property, without having to put labels from some sponsor on
it and whatnot, and hence I shall go without the perk of a
few grand in funding.
As for the state of Missouri I live in, no state funding for
conversion is available for all I can tell, as much as I'd
like to have it. I'm sure others from the state can correct
me and direct me to information, but I've had difficulty
finding it.
OT: Ryan, I've taken an interest to your 200SX. How much
weight have you been able to remove from it? Weight as a gas
car alone is more than 700 pounds over the estimated final
conversion weight you have on your austinev.org page. How
did you plan to get that thing so light? How much weight did
you strip from it? With a 156V dual string pack of Exides
instead of a 120V single string pack, you'd still never hit
2,600 pounds of weight, and that would be about the same as
the Spitfire I'm planning with only a 240V single string,
which is about 250 pounds less battery weight than what you
would have if you were to do a 156V dual string EV instead
of a 120V single string, based on the 1,850 pound curb
weight you gave on your austinev.org site. 0-60 in 7.5
seconds seems really quick for a 120V conversion and a Zilla
1k, I'd figure you'd need at least 156V to achieve that in
an 1,850 pound car. Maybe it's time for me to do some
calculations on the Pestolite motor.
Also, do you have a breakdown of all the parts you are
planning? $7,000 seems pretty cheap, or does that count in
the grants you are going for? The options I looked at minus
restoration for the EV I plan entailed more than $10k in
parts, and it doesn't seem much different than your proposed
conversion, except for the motor, which might be a WarP9,
and that the Zilla I have planned will be a higher voltage
1k. If I knew what parts you were using, maybe I can kind of
cut the cost down a bit...

It turns out that SJSU moved the list processor to a new server a while
back, and accidentally forgot to re-enable the attachment filter. I just
tested it, and the filter seems to be working now.
Thanks to those who alerted me to the problem.

this is kinda goofy, but how about:
- a light-weight collapsing-frame bike-EV (assisted human-power, perhaps
even a 3-wheeler - which are a riot to drive when small, light, and fast,
yet have excellent low-speed load-pulling characterisitcs)...
ok, pretty normal so far, but
- when no longer being ridden, the frame collapses and - voila, grown-up
transformer toy - can be reassembled as a tower structure, upon which the
motor is re-configured as a genset in a wind-turbine - great for extended
tour-camping!
Operation:
- collapse frame and reconfigure from vehicle mode to tower mode
- attach wind-turbine blades to motor (removing wheels/transmission/etc,
as neccessary)
- attach turbine/motor to tower
- charge battery pack from wind
The entire frame set (including: motor(s), wheels, turbine blades,
load-bearing platforms, structural elements):
+ shouldn't weight more than 30-50kg
+ should be configurable into a tower at least 2-4 meters tall
+ should be strong enough to support the weight and operational stresses
of the wind-turbine tower configuration and the vehicle configuration
... the size and weight of both the batteries/electronics and the total
passenger/freight load are user-variable...
...and, yes, PV (solar panels) can/should be exploited as much as
possible, and are counted as part of the entire frame set...
===
consider this an engineering challenge worth ten bonus points
bonus points sparkle if (any of the following):
+ vast majority of frame is not metal or unobtanium
+ entire frame set weighs 20kg or less
+ you build at least five of them
===
