Penjelasan NO atau NC

Berhubung sering melakukan projek DIY elektronik di rumah (pada mobil atau yg lainnya), jadi ga ada salahnya ngebahas sedikit tentang saklar..

Ada 2 tipe saklar yg umum digunakan, yaitu:

1. Self Locking (Push Switch)
Jika ditekan, tombol akan terkunci di dalam dan akan tetap di dalam walaupun jari sudah dilepas. Untuk mengeluarkannya, tekan sekali lagi.

2. Momentary / Horn (Push On)

Push Button

Jika ditekan, tombol masuk ke dalam, bila jari dilepas tombol akan keluar sendiri (mirip tombol bel / klakson). Juga bisa dibagi jadi:

a. NO (Normally Open)
pendeknya: dipencet on, dilepas off

b. NC (Normally Close)
intinya: dipencet off, dilepas on

mau penjelasan yg panjang? baca ini: SWITCH.

LED Foglamp on SX4

So today I plugged the new LED foglamp (which can be switched to strobo by fast-double-pressing the switch).

The process should be very simple, just open the front bumper, disconnect negative current from the battery to prevent airbag from deployment, disconnect respected wiring, replace the bulb with LED, and redo all the steps in reverse.

But in reality, the new LED has different polarity in the circuit, so I had to change the wiring to get it right. By doing so, I wasted another 15 minutes of labor.

LED Foglamp SX4

Jadi ceritanya abis beli Lampu LED (bisa fungsi strobo juga) buat foglamp SX4. Order online lewat salah satu situs jual beli di indonesia. Tapi sayangnya salah satu lampu nya patah, maksudnya lem housingnya lepas seperti yg bisa dilihat di foto. Jadi belum bisa dipasang dulu.

Besok lem nya bakal kering dan siap dipasang.. tinggal bongkar bemper depan besok siang..

Let’s see how it gonna be.. stay tuned!

I Take It Down

Some important elements in just can not work well without some big changes in the core system. It needs to be fully updated, from database structures to the API framework. It has to match the developments that have been done by Google Play and some of the android repositories. And to make it happened, I will need several days of my "silence-coding-day", which means i need to concentrate my attention to the project for the day. And also, it can only be happened in December.. Why?

site down

I planned that the site will up again next Christmas. Why?

New Project: Expert System

I got new client who needs my help to convert his proposal to a real web application. It will uses Expert System algorithm.

tipsAn expert system is software that uses a knowledge base of human expertise for problem solving, or to clarify uncertainties where normally one or more human experts would need to be consulted.  – Wikipedia

This is the most annoying thing, I “have to use an existing algorithm” to build this project, or at least my own algorithm in which the result MUST be similar. It made me decided to increase the price. Higher price than before..

Hemmm… bosen

Oh, by the way, this is the 3rd TA (Tugas Akhir) project I accepted. Normally, I shouldn’t accept those projects because they (my clients) studied for it (it refers to programming) for at least 4 years in their campus. And me? Only 3 years of weekly Pascal Programming training when I joined IT Club in Smansa Singaraja (and I didn’t apply for any IT major in any university, my shame).

The online demo is here:
