Take a look what's Inside !
I-POWER! Brake Booster.. hehe
what I've got to say!
WTF ! Photo of a house door for?
This is one of the interesting house @ Blk 52 , Bedok South Ave 3, #16-xxxx with interesting
group of people in Singapore for the past 20 years,
which many Singaporean don't know they existed
and what they do!! people who knew them are forbidden to tell including me and
my classmates (during 1987)... I was in the house TWICE!
and Yes! they are still hyper-active in both
Singapore, Malaysia and maybe other country which I don't know!!
Since they are long gone from this house and no one knows their current location, this is just a photo of the current
location.. if the current tenants saw this information on this page and what is
inside their house before,they would be scared!
I'm sure.
Now I know what they really do.. so I must reveal them!
ENERGISER Ignition Coil Amplifier
Device contributed by Weijie
20/09/2008 - box measured 90 x 38 x 18.5 mm
D1 - 30DF4 (Nihon Inter Electronic) FR, 400V, 3A.
D2 - 0.2v forward voltage drop.
Another "Monkey SEE, Monkey DO" Design! or it's properly done by the same group of people with different Brands?
INAZUMA VS
Device contributed by Decry Hardiyanto Zaidi
Another EZ-stab !
Another EZ-stab from Decry.. seems like it's basically the same thing
a cheaper version without
the "Power-saving!" mode.. :)
but he pay $90 for this... while
others are paying the same price for the extra capacitor and switch!
and a lot of empty space for such a big box.
I was thinking if there are plenty of different version around, since it is very
easily customizable.
A PhD design?? my 13yrs old cousin could do better then
this!
Another Air-charger ?
Interesting stuff...
It's a cheap gadget.. about $70+ fitted in Malaysia, but I still want to know
how it work's.. It's fitted in between the Engine breather (Cam cover)
and intake manifold
using a T connector. I got a spare unit for dismantle.. Later!
Z-Stab Ver.1 - Voltage Stabilizer
Device contributed by ALAN
I've received this gadget from ALAN on 19/08/2008, The box measured @ 12 x 6 x 8cm ..
It's weird to see designer using AC 50/60Hz(Alternating
Current) 250VAC capacitors on a DC application, as both AC and DC caps have
different frequency characteristics, C5-C8 - 100nF(x2), 8uF and 10uF / 250VAC non-polarized capacitors commonly
found on Mainline household appliances and it's the same type of caps used on
Mainline power saver. There is nothing wrong with AC caps on a DC circuit, which
I've asked around including people in electronic hobby and professional alike,
most would say "NOT RECOMMENDED" ! Or even recommend a 4uF/63 WIMA
caps for a low impedance effect, but this is not even used in a switching
circuit, so I would say any common Aluminum Electrolytic Capacitors would do the job.
Download a copy Aluminum Electrolytic Capacitors
Application guide here!
Here is another common Z-Stab Claims -
"And under certain operating conditions, balance
the charging system such that the alternator no longer forces energy into the
battery." - EZ-stab technical section
"Z-stab VS is used to bluff the alternator to think
that the battery has enough charge so it bypass it and supplies current to the
rest of the components?" - Reader's Email
"I heard that this gadget supposed to cut off the alternator
from charging the battery when the battery is already fully charge and in that
way, it channel the generated voltage from the alternator to other parts of the
car?" - Reader's Email
"NO WAY !!"
This circuit is nothing more then a device full of capacitors!!
All SLA battery charge at 13.8V (constant current charging) and anything above
14.2V (14.4V for some battery) will automatically goes into "Cycling"
self-discharge/Charge mode, information could be found at well documented
Datasheets. For those short distance driving and seldom use car, are un-aware
that your car battery might not be able to charge properly which 'feels' like a brand new battery is losing
charge.. There is no way for it to "Bypass, cut off from alternator or even under certain
operating condition" any of the two voltage detected at the voltage
sensitive electroplate, it
will do it's job.
'S1' switch according to ALAN said - "This switch is for
switching between Normal and Power-saving mode *while flipping the toggle
switch.. smiling* "
I think this function is more or less understandable
even by a junior electrician... (shown on schematic)
This circuit been designed by PhD (Permanent head
Damage) Jonathan Wong *or do I got everything mixed up? This circuit
looks more like a child's play to me :)*
If you manage to know one of this sort, don't introduce him/her to me, before you do, I'LL LEAVE TOWN !!
You can download a copy of
EZ-stab White Paper here.
The value marking of the AC capacitors are badly scribble off by some sharp
object (done by manufacturer),
but in order to find the value, I've use my capacitance meter to test the value of the caps,
A value of 8.848uF is shown on meter which is clearly a +/-10% tolerance 9-10uf AC caps, but the
actual value are not important.
I'll update if I've found more information on
this device... or you like to know more drop a mail.
This is the first version of
EZ-Stab called "Z-stab" and the 2nd version of
EZ-Stab is currently available on their
websites.
Spark Optimizer
Device contributed by ADZ HAIRIS
 
Sorry!! I've miss out the
RK44 (40V, Schottky barrier diode, 3A), which is a
suppressing diode, any schottky with recommended voltage rating should do the
job, an common replacement diode is 1N5822 (40V, Schottky , 3A)
I've just received the
X-treme Spark Optimizer unit from a
reader Adz Hairis today (04/07/08),the Aluminum rectangle casing is size at L83
x W31 x H19 mm. I don't know what type of compound they used to seal up the
device but it's as hard as Tarmac, after a few blow with a 5LB hammer, compound
started to chip off bit by bit... LOL!! what I saw is only 5 component and that for S$160?(Current
Price) It
contain only 2 Diode, Capacitor and a LEDs, RIDICULERS! This is
what they send to SPACE? ROFL!! Don't forget that this is made in
their own LABORATORIES where I could make hundred's of this in my own bedroom..! component 'D1' a TO-220 common cathode diode which is
hot glued to the capacitors, again who would want to dissipate heat onto the
capacitor? And with a forward voltage drop of 0.2 - 0.6 volts, it's secondary
output will definitely suffer a drop in voltage to the spark ! We are talking about 14v supply voltage with 25,000 - 30,000V output
to the spark! and 30,000 - 60,000 volts for C.O.P. and E-core ignition.
Look out for it! The new "DON'T NEED TO CUT
WIRE" design could be as simple as the schematic below:
Another crooks device made by
some local Singaporean.
(cost
to build this unit is estimated at S$5)
Who say this Device is GOOD?? I reckon! Properly ,some
had been told to say what they need to say!
" S$200 ... Rip off... RIP OFF " - ADZ
As a compliment, I've made Adz a NanoPulse-VS at a cost
of S$10. Cheer's !
Let me see..(need rocket science for this!) 5 component
for $160... my Nanopulse-VS got 9 Resistors, 12 Capacitors, 5 Diode, 1 Leds, 1
Transistor and 2 IC's ...ermm... WAHHHH !! I can sell this for S$800 Leh!!
... SHOW ME THE
MONEY !! :)
Device contributed by Glenn ... on his 2007 Mitsubishi Lancer
He's
edger to know what's inside this thing and how it work's and any improvement can
be done, by
looking at the qualities of both devices, they don't really works as expected
and definitely not a "HIGH PERFORMANCE" device. They both have professional
design stickers and rubbish point to point soldering circuits inside and all are
build in their own LABORATORIES :), as I'm concern I'm not going
to cut away
the potting compound and with a glance of view there's a 2A682K(0.0068uF) ,470uF
caps , resistor , LEDs and 10A fuse as shown on Fig3 , these are not going to
boost or out-perform in the electrical system as I can't see any
high-performance circuitry build in them. So the next time you are ready to
buy another similar devices get someone who knows about electrical and don't get
cheated by these sellers! As living standard are getting higher these day, there
will be more and more these type of product people would think of...or learn to
use a soldering iron at least!

Some of my old friend's had asked me the efficiency of
this spark optimizer thing, I couldn't answer them as I've never laid my
hand on it before, and nobody had any feedback or a picture of what's
inside the unit...NOT A SINGLE SOUL! Coincidently one of my
friends had a set setup on his car, so I asked for his permission to
dismantle the unit to have a look what's the layout and component inside
and do a few basic test on the unit.
Nobody bother about the Volt meter lah!!
