There is four other ways to do this.
One is using a MSD magnet crank trigger which uses four magnets on the
wheel. It has a pick up that you can send the pulses to the correct type of
tach. This is more difficult to install.
You can also mount four magnets on a aluminum wheel using a pick up that
send 12 vdc pulses to the tach. I got this kit from Café Electric. You have
to machine a aluminum disk about 3 inches in diameter, placing 1/4 diameter
neo magnets on a 2.5 inch circle.
Another way is to use the tach and sender kit from evparts.com which
requires a shaft extender off a pilot shaft. You just clamp it on to the
shaft and you can get the correct tach from them.
Or used a ADC sender and pickup for the ADC motor which you can also get
from any evparts.com or any ev parts source. You may have to get some other
accessories to run this on some tachs.

Ok, I'll take the bait....
I even posted a video showing the trap speed and time of the X1 from a
standing start. That easily equals a time slip. I can see the X1 being
snake oil to you John. Advanced foreign technology often gets that
kind of response. It does however advance the EV cause for everyone,
except you of course, since you are the pinnacle of technology ;) You
also claimed in that video to have the fastest ride around. Or was it
quickest? I thought that was Rod's domain.
X1 = 11's WZ = 12's. Is it even a race? Definitely not a technology
race. We all know who the winner is there ;)
With the advent of the Tesla, I don't know how the X1 will do
commercially. But technologically, it's hard to beat a very well
engineered frame and light weight components to make an EV that did
11's in the 1/4 mile it's very first time to the track and has
incredible range and efficiency.
Here's the url to the X1's 11 second run, from a standing start,
racing only the track timer. A little slower ET due to the wet track.

That's an enlarged roller skate with seats. To be fair, I have heard that

I've ridden in the X1. It blurred my vision.

Or "British flag" displays like
http://dkc3.digikey.com/PDF/T063/1960.pdf
Unfortunately, display type is a matter of taste more than engineering.
The display is the "face" of the product, and people will judge it on
appearance, fashion and style -- not readability or performance. People
will want whatever looks cool on the latest electronic gadgets in the
stores, and matches the rest of the stuff on their dash. So, everyone
will have their own (strongly held) opinions, regardless of how it
actually works.
9 out of 10 of the displays I see on products are terrible -- they look
nice but have fatal flaws. Common ones:
- too small to easily read (packs too much data into too small a space)
- restrictive viewing angle (can't read except from the right position)
- can't read with polarized sunglasses
- can't read in direct sunlight (not bright enough)
- can't read in darkness
- uses meaningless undefined icons
- gets dirty and smudgy and can't be cleaned
- wastes power (important in an EV)
- won't work at extreme temperatures (Arizona sun, Minnesota winter)
Overall, I like the vacuum fluorescent displays the best for car
dashboards. LEDs are my second choice, if you can get them bright enough.

If I understand it correctly, you want to use the fan motor voltage to
operate the relays? If so, this won't work.
The low/medium/high fan speed is accomplished with a resistor controller
(just like EVs in the 1900's). Low connects a higher resistance between
12v and the fan (~6v at the motor), Medium a lower resistance (~9v), and
High is direct to 12v with no resistor.
Relays depend on "instantaneous" application and removal of coil current
to turn on and off quickly. If you apply a low or slowly ramping
voltage, the contacts open and close slowly. This makes them arc more,
and reduces their voltage rating.
So, if you connect a relay coil across the fan, it sees a voltage that
slowly ramps up as the fan comes up to speed, and slowly ramps down when
the fan is turned off (it's a PM motor, and so acts as a generator). The
relay's contacts will quickly burn up.
If you use separate relay coils for each fan speed, each wired ahead of
the fan speed dropping resistors, the relays pull in fast, but still
drop out slowly due to the generated voltage from the motor.

Each contact of the DPDT version is rated 3amps at 150vdc MAXIMUM.
Exceed these limits and the life goes down fast. Two contacts in series
will be ok for your 192vdc pack, which could reach perhaps 250vdc during
charging.

It's clever to wire each element of the ceramic heater to its own relay
contacts. But what matters to the relay is the PEAK heater current that
it has to switch; not the average. I'd be surprised if the peak current
for *each* element isn't in excess of 4 amps. Test it at the coldest
ambient temperature, maximum supply voltage, and maximum airflow.
Heaters are tricky because the failure modes can be catastrophic. I'd
suggest doing a FMEA (Failure Mode Effect Analysis). This means you
consider each part individually; what is its worst failure mode, and
what happens next if it occurs? From best to worst-case:
Best: - system quits working safely, and user can tell it's broken
- system generates some kind of warning or alarm, but still works
- system keeps working, with no apparent consequences
Worst: - system sticks "on", melts down, starts a fire, etc.

I would not choose between the two. I think they have separate but
equal uses. As a guage the LED version rocks. For system info the LCD
did a nice job.
If I were going to buy one I'd pick the LED version.

Since the airing of the show I have been getting a lot of inquires from
Australia just as Chelsea has been experiencing. I have been referring them
to the AEVA, instructions for getting on the EV List, and various links. I
feel this show has had a very good impact down under. I think the scene of
John Wayland blowing away a muscle car had the most impact but I must admit
that I am performance prejudiced. It is just that the image of EVs has
always been that of a slow vehicle. The short lived EV1 did a lot to dispel
that myth in certain areas of the country. The sad truth is that most people
in this country had never even heard of it. So much for "the award winning
add campaigns" that GM claimed.

Just for reference, most tachometers are an analog meter movement. It's
basically a voltmeter with a resistance of about 200-1000 ohms of
resistance. Full scale current will be about 10ma or so.
Any PM DC motor makes a fine RPM sensor. At light load, the voltage it
generates is exactly proportional to RPM.
So, a tachometer can be as simple as any little DC motor, coupled to the
back shaft of your traction motor, connected to your tachometer (or any
voltmeter), with a series resistor to calibrate it.

Plug in America and glad to see all the what's going on there, and the great
links. Seems it;'s time to get the Worlds' EVers together. A International
EAA? Why not? I'll bet there are people all over the world that would chime
in?There IS a Japan EV Club, or group thing there. China? Hello, China?
France, I know, England, there are a bunch of guys from UK on the List

Maybe "Plug in the World" is next?
