bought those caps for around RM70bucks pcb board and wires... however it didn't work when i tested with a computer 12V DC power supply.. it only managed to go 1.2V instead of a steady 12V.. i wonder why.. who wants those caps i offer at RM30.. 2pcs 4700microfarads, 8pcs 3900mf, 6pcs 2200mf, hows that?

I wonder he means he is trying to simulate 12v DC power supply in car battery la.. <_<

 

[jaywat]

but ufo, u manage to go through all the post...

RESPECT! :ph34r:

erm... i'm using 85c caps... but my VS casing i got put heatproof material (superlon)

n i'm using 16v caps....

so far no probs... even last time got one guy very sure 85c caps will burst if use on his waja... he bought my DIY VS to try.... well i guess its fine until now so long already he din call me... :P btw he was my 2nd customer...

 

[jaywat]

khguan, when do u wanna mass product the VS??? :lol: :lol: seems like can get some profit also hehehee :D

 

[khguan]

mass production ah? i duno how to do dat wor... now i onli manufacture it by myself.. fully handmade by me...

well... no plans for dat yet... now i'm stil like a "pasar malam" VS seller.. :P just like ppl selling nasi lemak in small quantities... :lol: i complete few units onli very fast finish... now wanto get more cash 1st.. then i wanto get in more stock once... no need travel here n there to get my stocks..

 

[jaywat]

You need an assistant?!?! :lol: :D :lol:

no such thing lar.... battery recharge n discharge is using chemical reaction... n chemical reaction need time to happen...

caps is diff.. charging n discharging is using dielectric materials.. so no chemical reaction... just de flow of electrons... dats y it is fast....

rite or not? pls correct me if wrong... B)

[snapback]823834[/snapback]​

For normal batteries, you're right... But lately since there are some new electronics which requires high amps that normal batteries could supply, newer batteries has to be invented...

Thus, why not use Li-Ion? They have very highdischarge rate... But I'm not sure about the charging rate...

 

[khguan]

well.. i think a voltage stabiliser need to work like an car shock absorber... it need to have fast bound n rebound rate...

if de voltage is constantly fluctuating.. then de charge in de battery may not b enough to stabilise de fluctuations... cos de charging rate of batteries is slower than discharge rate...

am i rite?

anyone have build one or want to sell it pls pm me !
coz i am lazy to do it myself i just want to buy a instant one...hehe
anyone want to let go ?
pls pm me ! thanx

Ahah...
So here's some pictures...
Warning: Very ugly Pics:lol:

Here's the setup. The multimeter poking to the battery teminals where the VS is installed. A torch light cause it's night time...And... a bunch of my DIY grounding cables.. very very messy. :P

Top View... The VS is installed in front of the battery just after the headlamp...

These 2 pictures... with the engine off (Fluctuating a little probably due to the engine was on just a moment ago)

When the engine is on, the voltage is very very constant and stable at 14V.

Fuse and LED...

My battery contact HAHAHA!!!...

Just because I was lazy to drill a few freaking holes on a metel piece or something? :P

thanks...

Hey ufo dude!! you are answering all those "backlog" questions lar...i think they are all very happy and satisfied with their own VS now ;) hahahah

[snapback]824088[/snapback]​

i guess so.. was a newbie here, started mine DIY, not satisfy, as i compare wit a commercial VS.. i can see there r other things included other than jus CAPS.. :ph34r: put me in ur group , i might share something wit u guys...

Well ufo, for DIY we took some tryings lo. I produce my first VS without any improvement to my car. So i produced another VS with different sized CAP, my car feels better now but still not as good as i expected. However, my friend curi curi took my first VS and went trying on his 8 years old satria, <_< he is amazed with the effect the VS gave him hahahahaha :D ... it just didn't work on my new car lo :lol:
