Here it is then..
The diagram. This diagram is using multiple capacity cap. The number of caps is up to you, some say more or bigger capacity is better.
What u need;
-( 4700uf, 16V/12V capacitor ) x 4
-( 3300uf, 16V/12V capacitor ) x 4
-( 1000uf, 16V/12V capacitor ) x 10
-circuit board
-box
-wires
-fuse holder
-wire terminal
Sorry for the bad drawing. The basic connection is like in the drawing but u can use your imagination and creativity to place it on the circuit board in order to save space or have the better looking end product. For the fuse holder, u can buy one at any spare part shop.
As i discover when i did this in 2008 is that the shop did not have much stock for capacitor so not all VS i made is using the diagram above. This is another design i made using only 4700uf capacitor.
In this design, there is also an LED indicator. Do remember to connect a 1k resistor to the led or it will burnt upon connection of the terminal. I just used normal auto wire in the VS and it works just fine. To make it easier to connect, i also uses the green wire terminal and solder it to the circuit board.
If i recalled correctly i made lesser of the VS with multiple capacity capacitor compared with the single capacity capacitor as thats the most commonly sold capacitor. 16V will do fine.
