Turns out there weren't as many parts as bikes. Mr. Electric didn't exagerate.
Almost complete bikes. One or two experiments with very good parts. If you are in
the bay area and would like some stuff email me and come over and pick up a nice
glider with or without a motor. Got batteries too. Etc.......Etc...excess
parts..........Trade, barter, fix something or just free... Lawrence Rhodes...

Subject: Free Vego Parts
I am the warranty service person for Vego and a few other companies.
I will be moving to a new workshop in about 1 month and I want to
lighten the load. I have a large bulk of free parts. Mostly Vego
some others. Vego is not closing I am just getting rid of overage of
parts. I would like to give away everything not just part out the
good stuff so be ready with a van or pick up truck. Parts include.
Dead IQ 450's, Good motors, Battery caps, wheels, Forks, seats,

The idea of running the keyboard off of a separate amp from the p.a. is so the keys
wont distort the p.a. when the key player uses the lower (bass frequencies) registers.
It would only be normal that low bass freq's off of most any keyboard would distort
p.a. monitor cabinets meant for middle (speech/vocal range) frequencies. This is the
prime reason that bass players (like me) need to have the highest power amplifiers
with the best slew rates, and the fastest cone drivers we can get our hands on (like
hartke aluminum cone 10's 8 to a cabinet.)
As for running musical gear off of inverters, I personally have ran a 300 watt sunn
colesiem bass head of a $79 (at that time...1972) 300 watt radio shack (tripp-lite in
r.s. clothes) inverter into a 2x15 jbl loaded bass cabinet across the back of my old
'68 chevy van and yeah, while it buzzed a bit, it was THE LOUDEST car stereo(mono)
ever heard in the county of Solano for its time. This was when Jensen 6x9's, 8 tracks,
and the audiovox 40 watt "booster" were the car audio bill of fare of the time.
Everywhere i drove heads turned ... no one had ever heard such a thing back then!
I also had alot of juice constantly being poured into my batteries by the cars
alternator, hence the batts never wore down wich is what the problem I see with
running a 1kw sinewave inverter off of a couple of YT's. Power out = Power in so a Kw
at 120 volts is still at least 100 amps at 12v. Here at work in the ENG vans there
are two grp27 deep cycles set aside in the installation just to run the 2.5kw
inverters.
I HATE to bring the thought back to generators, but I've tried running my band off of
generators...7Kw... 12Kw... gas runs out at the wrong time, they're noisy as heck, if
your doing this in the summer heat, you have to give it some cooling... eech...
painful, but sometimes unfortunatly---neccessary. Theres only one small genny I would
RENT for doing this type of gig...the Honda EU3000. It's SO quiet (58db) you can stand
next to it and have a conversation. electric start, doesnt stink, and its an
inverter/generator. A dc generator coupled to an ac inverter -- apparently alot more
efficient. I only wish Honda would make these in a larger size or allow them to be
stacked like you can with they're EU1000's

Yeah but I bet different amps run on different voltages; you can't get
high power from 12V without stepping it up, for example. (But you
could use a car amplifier which has the step-up DC/DC converter built
in.)
Also I wonder if any of the stuff depends on the isolation provided by
having a transformer - i.e. chassis ground and signal ground and power
ground are not always meant to be connected together. I'm planning to
use a PV/battery DC power bus at home pretty soon (for computers, the
ethernet switch, some lights etc.) and have been wondering if I will
run into any problems like that; and if the racks I mount stuff in
should be grounded both to the negative battery terminal as well as to
earth; etc.

I think i could post here about a gasoline Webasto 5Kw water heater i have
for sell.
It was in my now crashed peugeot 106 electric.
There is a problem with it: the entrance coolant pipe pump head is crashed
so you need finding another suitable pump or fixing-it (difficult way)
Price is in consequence, just give me a serious offer and its yours.
you can see spec and model here:
http://www.webasto.us/am/en/am_marine_heaters_823.html
I sell the complete motor/drive train (22 000miles):
It is a perfect working condition 120V Leroy-Somer Sep-Excited motor, 11kW
nominal, 12.7m.daN,
reduction gearbox 1/7.2
total weight is 160lbs.
pictures here:

The cheap and dirty way might be to get a cheap 600+VA UPS. Cut out the
warning buzzer, take out the batteries and series/parallel your YT's to get
the same voltage. Install a small fan for extra cooling. Before hacking
the thing, make sure that it's the kind that doesn't require AC to turn on
the load. (Some won't turn on the load until AC is detected.)
BTW, unless you already have the YT's laying around, you'd be better off
with cheap golf cart batteries.

You may not have time to complete this but,.....
I would bet that all of te equipment that you are planning on
running has power supplies that convert the incoming AC to DC.
If you can bring an access point to that DC out to the case then
you can directly connect the proper DC voltage and not have to
worry about an inverter or hum. (I find it very difficult to get
hum from a battery ;) )

Most people will be coming up the hill at 20-25mph in their gas
cars (it's a tight uphill lane with a curve swinging through
about 120 degrees to the right). As for EVs, I have been in or
driven vehicles with higher voltage packs. Back in 1994, the
120V Chevette (10 12V floodeds with 1221B controller) would do
this hill in the low 20s in 2nd gear. More recently, a 144V
(16*8V floodeds) Cabriolet carrying two people ran out of steam
about two thirds of the way up going in 2nd. I warned him at the
bottom that he'd better be in the gear he wanted to be in for the
whole hill. He petered out to a stop and could not get started
within several attempts. He didn't know how to use the emergency
brake to keep the car from rolling backwards (and it rolls
backwards in a hurry!) when dealing with the clutch.

things!

Several years ago, I scoped out options for going to a higher
voltage (more fun!!). The one I really wanted to do was two
strings of 144V of Optimas. About the same amount of lead as the
pack I have now (1050lbs), so maybe the same range if I keep my
foot out of it (but why did I raise the voltage?). 24 Optimas @
$125 apiece is $3000 (and will probably be facing a renewal every
three years or so - ouch!!). New battery racks, charger, DC-DC
are going to be about another $2K or so. So ~$5K to upgrade to
this plus loads of time (not just my own).
Or a single string of Optimas (144V at 12 batteries, so half the
lead). $1500 worth of batteries. Range unacceptable. New racks
and DC-DC converter still required.
16 Optimas for a 192V pack. $2000 (and every three years too).
New racks, new controller(!), new DC-DC, new charger. Probably
still $5K.
Nope, the cheapest upgrade would be 16 8V batteries for 128V
pack. What are these batteries, $100 each? Probably the only
real equipment change would be a new set of cables and lugs, so
just a few hundred dollars there. I'd probably be coming up the
hill in the low 20s - big deal! Most people I've talked with
indicate poor service life with 8V'ers. Oh, new charger (I'm
certain Rich will be happy to oblige :-) ).
As I live in an apt and don't have access to a garage of my own
where I can do this kind of work, and the car runs reliably at
its level now (and pretty much has for the last ten years), I
don't see changing it till my circumstances are different (mainly
my own shop and a place to leave a car in pieces). Sometimes I
look at EVs where people are trying this and that, and the
vehicle is never on the road and being used, and I wonder what's
the point. I like to play, but am limited by circumstances (I
gotta get out of this expensive county - Marin!).
Also, I don't care what the gassers think anymore about this
vehicle. When they're into big SUVs and endless
corporate-created convenience and dammed be the consequences, and
aren't willing to have an open mind, then they're irrelevant to
me and where I want to go. Fact is, even if I'm running on a low
pack and come up the hill slower still, after 5 seconds of
clearing my rear end and the top of the hill and then bouncing
over the speed bumps at warp speed, they've forgotten about me.
It's one reason I don't have "electric" emblazoned all over the
rear of my car. (I may eventually do something like "electric"
in place of the stock "diesel" or "fuel injected" on the tag on
the hatchback.)
Oh, if it makes things any better, more than half the time I'll
come up the hill without any gasser following me. It mainly
depends on the time of day. And I've also caught gassers going
up this hill with my electric - somebody just taking their time
in our speedy world, or a big truck.

I've flat-towed my Rabbit (~2900-3000lbs) with my '86 4Runner
(4-cyl, basically half-ton pickup). I think the 4Runner weighs
about 4000lbs. 7000 lbs coming at you down the road, with the
4-cyl doing all the work (the gas mileage sure does seem to drop
from its regular 22-25mph). It actually doesn't tow too bad,
although the performance does take a hit. Main thing I think is
the lag from making a move (like a lane change) with the truck,
and the little bit of time before the Rabbit's steering takes
notice. It wants to swing the rear of the truck, but so far it's
been no real problem. So another big thing was to insure I could
get the train going on my hill if I got stopped by an obstacle.
Tested on another hill of about the same steepness with lots less
traffic and wider road. Required being in 4WD-low to get her
going. Use emergency brake to hold the train while doing the
clutch thing - got pretty good at it. And hey, that 4-cyl will
pull the whole train up the hill about as fast as the Rabbit will
go on its own (I'm sure that will tickle Rich per previous
message). Thermo-fan comes on sometimes about 3/4 of the way
up. I've left the Rabbit's tranny in neutral for towing so far,
and have not had problems, even 100-mile tows. I may change the
routine, though, to putting it in 4th. Am getting rusty on the
tow scene - haven't towed to anywheres since 2001. Now what's
this big hitch thing...?

Per your 2nd paragraph, Shawn, isn't the way it's normally done
is to tie the chassis of the inverter to earth ground, and then
run all the rest of your grounds on the AC side of the inverter
through its AC ground wire?
I'm dealing with this same issue, as I want to put the computer
on the end of an Exeltech powered by the spare batteries for the
Rabbit (better to exercise them that way than use a resistor, and
I get away from the grid). The added complication is I still
want the present surge protector (which has brown-out protection)
between the computer and inverter to guard against any inverter
funk (and how cleanly does an inverter shut down if the batteries
get low?); also that surge protector handles the telephone line.
I'd also like to add a means to shut down the computer gracefully
if it detects the batteries are getting low (most computer UPSs
can do this kind of thing).
I wonder if there is a forum that discusses these issues? The
knowledge is probably archived somewhere.

Thanks Darryl. That is quite a database... pretty soon we will have
documented 2000 people who went out of their way to get that which we
supposedly don't want.
And I'll have to send a few updates along.

Anyone happen to know what the specs are for an "ITS" inductive throttle
used in golf carts? (Besides expensive...) Like what would be involved
in making one?

Yup, I remember some of it.
It's a 1 mH coil driven by a 555 circuit buffered through a bunch of
hex drivers or some such. It puts the rectified input across the
coil, switching it in a bipolar way at about 15khz and the whole
circuit draws about 1ma idle. Then when the core with a SS collar is
pushed inside the coil it increases the load on the circuit to about
5ma. The controller measures the load on these two wires and uses
that load as the input.
Look up patents from Curtis and you can probably find a better description.
I've run one of those controllers with a 10K slide pot and maybe a
resistor or two. It was many years ago so I don't remember exactly.

Beware! The battery is NOT isolated from the AC side of some inverters!
I blew up a perfectly good inverter, E-meter, and the serial port of my
PC finding this out the hard way!

Heck no. Well, Trojans at list price might be close to that, but I paid $53
each (plus freight) for the last pack of US Battery 8VGCs I bought.

Looks cool, but 10x what I spent on the Rabbit ($500). For now that's
all that is in the budget. Learning about series wound stuff and Curtii

IMHO, they figured out that Toyota actually knows state of charge and
doesn't guess and after some trying, figured that it was cheaper to
license the technology than keep trying.

That is a fact.
Not surprising, i suppose. I drove in the Escape
Hybrid a little over two years ago (one of the drive
train tuning prototypes) and it was a mess. Granted,
they were still fiddling with tuning parameters, but
at constant speed on the hwy, the ICE was hunting all
over the place trying to decide whether or not to
charge the batteries. It was very distracting.
Ford's spin, as I heard it, is that they are licensing
the hybrid technology from TMC so that they can focus
their R and D money on the 'next thing'. They continue
to see hybrids as an intermediate step.
Overall, i think it is good news, because it brings up
the volume and may lower the cost of the hybrid
powertrain parts. It also rewards TMC for being an
industry leader, which is a good thing (protectionist
politics, notwithstanding).

While I admit this would make a wonderful glider, my hunch is that this car
is basically unsalvagable as a insight.
Why? Well, think about this. You've got a multi-hundred-volt traction pack
and inverter, and water goes rushing through it. Do you really think the
damage stops at the computer?
My hunch is that any intelligence in the battery control system and most of
the inverter logic are toast

After a look, it seems group 24 DEKA batteries fit where the T-105s
are. I will have to do 2 parallel strings, as I have a 72V controller,
but that's fine for now.THat's 160Ah at the C/20 rate. Not as nice as
the T-105 at 225Ah. If I can find a deal, I still might do that.
I am starting to think a controller with a 200A battery limit and 600+
motor amps might be more fun if I got 144V or more.
Incidentally, at full bore I was pulling 277 (ish) battery amps doing
sliding around in the snow tonight... That's on a Curtis 1209B 400A
nominal controller that was about 0C/32F.

Oh yeah, a few other things:
Haven driven mostly Forces up to this point, I was actually SURPRISED
at how much pep the 6.7" and Curtis 400 had. Now Forces are know for
(miserly) efficiency, not being rockets. I haven't done any high speed
duty yet but in the parking lot up to 25 mph or so (it is a big lot),
it seemed useable. I know Madman will think I am nuts, but this is
supposed to be a station car first. The 47 gigawatt stuff doen't get
installed until next month :)
One thing that comes to mind is that this is about the cheapest way to
try a parallel ultracap system (72V nominal).
Finally, I think I am going to get a 1988 VW golf to transplant this
stuff into. My brother has one he wants to get rid of. GTI wheels&
brakes. Not pretty, but better structurally long term. Then I would
feel safe enough to add real power and expect it to last. For the
short term, I might just weld in floorpans.
I can't see using Invicta GLR tires on a station car, so I think I am
going to swap tires with my (offlist) friend with th NiMH Force who
actually commutes, so he can see what difference it makes. They would
probably get me an extra 200 yards of range that I don't need...
Thanks again to Bob Rice and Mark Hastings, and Electro Automotive,

Hi Jim,
I was curious about that too when I was playing with one of those old
curtis sepex controllers you passed my way. In the end I just used a
50k audio pot I think :-) Seemed to work ok. Got full range of PWM
and no smoke or warm. cheers

Mmm... You probably got what is called a "good deal" on the Rabbit.
$5k-7k seems to be the entry fee for a reasonable EV.
That said, I wonder what it would cost to equip an Insight with a small
AC system and maybe 500lbs of lead.

Good memory! I never thought to look at patents, but sure enough,
#5,247,253 sounds like the one - I just need to find the full images
that go with it. Some excerpts from the text:
"
... Oscillator ... 555 timer ...
... two banks of ... inverting buffers ...
... coil inductance is about 10 milliHenrys ...
... operates at a frequency of 16 kHz ...
Of course having electronics in the throttle box rather than in the
controller takes away from the advantage of having an inductive throttle
that could otherwise tolerates more moisture, dirt, etc. I was thinking
more like the Raptor/T-Rex with the coil & plunger.
Specifically I have a new controller to put in an ElecTrak E-20. A
linear motion plunger style throttle would be an easy retrofit for the
pedal to pull down on. The controller (AllTrax) can take either 5K pot
or ITS input. I have the standard Curtis potbox, but it is not an easy
fit into the little box above the pedal and would be prone to water/dirt
damage. Hmmmm....
