Heavy Duty Ignition Coil Booster

Heavy Duty ICB

Heavy Duty ICB

Masih penasaran dengan performa ICB (ignition coil booster), beberapa hari yang lalu saya buat yg lebih besar dengan kapasitor bank  72000uf dengan harapan supply arus koil lebih mulus dan lebih stabil. Kapasitas 72000uf didapat dari 4 buah kapasitor Nichicon 18ooouf 35V yang diparalel. Tadinya kapasitor tsb untuk bikin chip amp (GC) , tp karena stock lumayan dipake juga untuk ICB ini.

Konstruksi menggunakan PCB power supply amplifier 4 elco yang ada di audiobbm store. Skema sama seperti ICB terdahulu dengan dioda schottky yang lebih besar.

Stok elco Nichicon 18000uf/35V.

Empat elco besar dan dioda schottky dipasang pada pendingin agar ICB ini lebih tahan “digeber”.

18000uf 35V X 4

Hasil test menunjukan bahwa tegangan pada jalur coil tetap stabil walaupun gas di hentak. Efek dari ICB mungkin tdk banyak, hanya saja tarikan terasa sedikit lebih smooth. Sayangnya saya tdk sempat merekam hasil ukurnya, karena ini pesenan orang jadi sdh dikirim ke yang pesan hehe.

Berikut foto yang dikirimkan oleh pemiliknya dari pulau dewata. ICB dipasang pada Opel Optima.

Pemasangan ICB pada Opel Optima. Terlihat bentuk fisik box hitam pas masuk diruang mesin Sedan ini.

 

 

Another LM3886 Amplifier Project

This is my other project using IC LM3886. A complete LM3886 amplifier with tone control(Bell Bifet HK201), subwoofer filter (Bell BE-SW2075), and speaker protector(Bell HD 40A). Except PCB for ic LM3886, all using the available cheap kits I mention above.

Standard component in the tone controller gain more attention, I replace it with better components. In addition, all coupling capacitors replaced using MKP capacitors.

Here are some photographs…

2.1 Home Audio System. Using LM3886 chips, with the best value audio  grade components in the market.

Assembled Components on standard HK201 Tone control. The result is not too bad .

 Testing and Checking

Some people said this tone control is noisy, but I think I succed to reduce the noise to a low level.

Some test is important to achieve a good result.

When its all done, I send it to a very nice person in Gresik East Java.
