Lama banget gak posting something di sini. Terlalu banyak hal yang menyibukan. Bukan berarti gak ada sesuatu yang di hack. Hacking all the time pokoknya. Thanks buat yang sudah baca posting di sini, terutama tentang HHO. Banyak juga, yang minat ternyata. Ok, semoga selalu ada waktu untuk posting sesuatu. Hack something, know something.

HHO Generator

2008-08-11T06:43:00.001+07:00

HHO Generator ini akhir-akhir ini jadi tren. Banyak di klaim sebagai penemuan orang indonesia, padahal sudah di temukan sejak sebelum negara ini berdiri, hehehe. Penggunaannya biasanya untuk membantu penghematan penggunaan BBM di mobil atau motor. Saya sendiri juga penasaran ingin mencoba, berikut adalah HHO cell buatan saya dengan biaya yang sangat murah, tapi hasilnya mantab. Saya buat untuk mobil dan motor. HHO cell untuk mobil saya buat dari penggaris stainless 40cm sebanyak 14 buah. Perbuahnya seharga Rp.5000,-. Dan baut stud stainless, dengan harga Rp.10.000,- per meter. Total biaya pembuatan dibawah Rp.150.000,- Untuk motor HHO cell, saya juga buat dari penggaris stainless steel, sebanyak 3 buah. Total biaya pembuatan Rp.50.000,-

Mind Mapping for Guitar Learning

2008-06-11T12:27:00.000+07:00

Kalau belajar gitar, biasanya kita bingung harus belajar apa dulu. Yang paling efektif adalah mempelajari semuanya tapi secara terstruktur. Mungkin mindmap ini bisa sedikit membantu untuk mempermudah proses belajar gitar. Saya biasanya mempelajari beberapa node sekaligus dengan waktu yang tidak terlalu lama. 10-20 menit tiap node. Have Fun

How to open and replace Nouvo/Mio CVT Belt

2008-06-09T17:00:00.000+07:00

Motor matic Yamaha Nouvo / Mio, tidak menggunakan rantai untuk transmisinya, tapi memakai belt bergerigi. Umur pakainya menurut manual adalah sekitar 25000km. Kesan awal memang agak susah membuka atau mengganti bagian transmisi dari Nouvo/Mio. Searching di google juga minim site yang membahas cara gantinya. Berikut cara penggantian belt CVT Yamaha Nouvo kepunyaan saya. Buka semua baut-bautnya. Open up. Dan jangan lupa bersihkan debu-debu, dengan menggunakan kompresor angin. Senjata rahasia. Tidak perlu alat khusus untuk membuka rotor cvt. Cukup dengan "Impact driver" alias obeng ketok. Berhasil... Periksa juga roller pemberat di bagian dalam rotor. Sebaiknya di ganti juga.

Line6 Pocket POD, 32 Amp on your pocket

2008-02-05T21:32:00.002+07:00

I've just found Line6 Pocket POD from local music store. It's quite rare at Surabaya. But i found it and buy it. It's another product from Line6 POD modeling effect family. It's have about +300 custom preset in small packages, yes it's smaller than any stompbox, it's have similar size with tuner. We can customize preset, mix and match between amp, cab and effect, with free software from Line6, or just download preset from www.customtone.com and then upload it on your pocket POD. What inside ? Small room for modifications. But i think it will have better sound quality if replace all cheap capacitor with high quality caps. The engine...

How to open engine center bolt

2007-11-19T10:52:00.001+07:00

Center bolt, crankshaft bolt, or everything you named it. It's the hardest bolt on the engine. Always painful when we want to open it. On my Suzuki G16A Workshop Book, it's have Tightening Torque around 130Nm which mean very hard to open.When your engine still mounted on engine bay, it's not very difficult to open. Just follow your manual. But if your engine is not on engine bay, you will cry for help. What if you want to open it by yourself ? without help from your friend ?. I found the answer easily. Just mount your engine to your wall with bolt. and push your wrench hard..Its the cheapest engine stand. Bolt is 10mm dynabolt. Use transmision bolt hole for pattern.

Reason for head job

2007-10-23T08:16:00.001+07:00

I'll show you why i need head job a.k.a porting and polish for Suzuki G16 MPI 16V SOHC. There is some rough casting on intake manifold, as engine need smooth air flow this should be removed. and, there is distinct ridge on intake valve on transition between casting process and machining process.exhaust manifold.. in chamber, there is manufacturing defect, can do nothing for this. but for this can.. there is small area for unshrouding valve seat, it's dangerous as it can reduce compression ratio. and some port matching.

Replacing front disc brake pad

2007-10-09T20:23:00.001+07:00

It's just routine. Replacing your brake pads when its already thin. Loosen caliper bolt. Thin pad. Use C Clamp to put the caliper cylinder back on zero position. Dont use hammer or other tools, or you will damage the caliper. New meat... You must replace both Left-Right brake pads.

Tracing ECU Pinout

2007-09-22T10:11:00.002+07:00

When i have plan to swapping my Suzuki Vitara Carburetor Engine with EFI Engine, i need right ECU or Engine Control Unit. It's difficult to find Suzuki Vitara genuine ECU here. So i found closest alternative from Suzuki Baleno mk3, part number 33920-60GB1 . Both have same engine type, and same injector configuration. My engine is old version, it's have 2 injector on at once. Main problem is, i didnt find any information about this ECU pinout. Tracing it one by one is almost impossible. With some guts, i try to open ECU casing, and found pinout label printed on pcb. And after comparing with several Suzuki Baleno Workshop Manual, i found each pinout function. Show in picture #I0 = Injector 3 & 4 ISC = IAC Valve EGR = EGR Valve OXH = Heated Oxygen Sensor FP = Fuel Pump Relay RFC = Radiator Fan Control Relay GC = Blank PSS = Power Steering Pressure Switch STA = Starter Magnetic Switch +B1 = Power Source E1 = Ground Next time i will post my homebrew ECU.

Rear Brake Problem

2007-09-04T21:02:00.001+07:00

One day, i found vitara rear brake is not working well, when at parking position, brake pad always stick on it's drum, and brake oil tank need to fill at least half tank, once a week. So it must leakage problem. Rubber boot problem...... After open brake drum, i replace master brake piston seal, and its rubber boot. Just make sure the rubber boot is good and tight. I buy rubber boot for Isuzu Panther at nearest shop. It's hard, and tight enough for Vitara master brake cylinder.

Passive Crossover for JBL GTO426

2007-08-19T19:05:00.000+07:00

I use JBL GTO426 4" series speaker on my car. It's coaxial speaker, with affordable price and high quality material (not high quality sound). I use GTO426 because i dont want to see tweeter above my dashboard. And GTO426 mount perfectly on Suzuki Vitara dashboard speaker mounting. Sound quality is far from great, not even good. Middle sound is very weak, high frequency sound from tweeter is not sharp. Mostly i play Metal, Heavy Metal, and other song that have heavy guitar distortion, like Metallica, Megadeth, Linkin Park, etc.. The GTO426 unable to reproduce that heavy sound distortion from my Alpine HU. My decision is to look at the speaker and add passive crossover for woofer and tweeter. I think JBL make very good product, so i am sure their product have better potential quality. JBL GTO426, using small capacitor 3.3uF/50V as 1st order high pass filter for tweeter. The capacitor is made by well known taiwanese audio grade capacitor manufacturer, Bennic. From that value, i know the tweeter have cut off frequency at 6000hz, and i use this as initial value for my 2nd order passive crossover. From my calculation (I use Linkwitz-Riley equation for first time) i will need 1.65uF capacitor and 0.42uH inductor, both for LPF and HPF. First, i build on prototype pcb, or known as "PCB Bolong-bolong). I use "most bang for the buck" high performance capacitor made by Solen with capacity 3.3uF in series for HPF, and 0.47uH inductor which is closest value available on "Pasar Genteng" electronic market. For LPF i use lower grade capacitor made by Bennic with same value. The main concern of this modification is price, so why i spend 1 juta rupiah on 500 ribu rupiah speaker. Result is very significant. Middle frequency sound is better, but, high frequency is to sharp and bright. First test, i play Jack Johnson - Better Together, sound detail is good, i can hear detail from guitar string, but high frequency sound is too sharp. Second, i play Megadeth - Angry Again, the sound is more crunchy, vocal is more clean, and instrument layer is more detail, but cymbal sound is very sharp. But overall result is good. After some inspection, i found that inductor value is not consistent on 0.47uH, one inductor is 0.49uH, and three inductor between 0.46uH and 0.47uH. All of them need some minor value correction, so i done that, and have 0.42uH. And sound test result is more better. High frequency sound, is not too sharp anymore, middle sound is more powerfull and crunchy. This "100 ribu rupiah per-ch crossover" is satisfying, sound from JBL GTO426, is very crunchy, heavy and details, i dont know what if i use lower frequency cutoff, or higher. Maybe better ?
