Gagasane-paper berawal dari keprihatinan terhadap minimnya daya tampung karya-karya ilmiah populer yang dihasilkan para siswa sekolah menengah lanjutan di negeri ini. Terbatasnya media penampung membuat karya-karya itu kurang terpublikasi. Padahal, sebetulnya karya tersebut bisa menjadi masukan yang berguna bagi masya- rakat.
Introduction How to Build SMPS Transformer Home Make 12V 10A Switching Power SupplyWith the transformer from old computer PSU. I try to make 12V 10A SMPS at home. I use SprintLayout for make PCB and iron method for make PCB board. In this video you can see me windings the SMPS transformerFor easy make PCB you can download my gerber file below and upload to for make PCB online 1 Design the PCBI use SprintLayout one of Rusia electric software for design PCB and print it to calendar paper. I always use calendar paper for print PCB because it cheap and good qualityStep 2 Make a PCB by Iron press MethodThe first we need to cut the PCB exactly the PCB we print on calendar paper. After that we use the iron press to the PCB about 5 minute at maximum temperatureStep 3 Complete Make PCBWe put the PCB into water about 5 minute. After that we take the paper out and put it to FeCl3 liquid for 15 minute or more...then put to water again and clean make the PCB take alot of time so for easy you can make PCB online. I usualy make PCB online by upload the gerber file to for get PCB only 2$ for 10PCB. All file of my project include gerber file below. 4 Drill PCB and Solder ComponentMake the hole for PCB and solder component. I had attach the layout picture you just put the component to exact of component can order online them from 5A 275/250V filter diode RS507 150K 150uF/450V 5D9 27k 33K/2W Mosfet 20N60 x2 27ohm X2 224/100V UF4007 1N4007 MBR20100 15K 102 100uF/16V 105/600V 4K7 5mm 2k2/2W 2200uF/50V and transformer heatsink we can take from old computer PSUThe Transfomer we need windings 5 Take Out the Old Wire From Transformer and RewindingsPut the transformer to hot water in 5 minute. after that we can get the ferrite core. windings the transformer we use wire with primary 40T and secondary 5T for get 12V output. At the output with big current we use 6 wire together. Each layer must to use insulation tapeStep 6 Solder Transformer and First TestSolder the transformer and test the circuit. In the first test we must connect with 60w/220v light bulb before plug to 220V. If the circuit fail the light bulb will on and we safety- Трոху ሄитвαμоскω

PowerSupply komputer menggunakan sistem SMPS (Switching Mode Power Supply), yaitu sistem power supply yang menggunakan metode pensaklaran tegangan dengan kecepatan tertentu (frekuensi tertentu). Hasil dari pensaklaran ini berupa sinyal kotak (pulse) diinduksikan ke sebuah transformator (primer) untuk menghasilkan beberapa tegangan output pada sekunder transformator yang kemudian disearahkan dengan dioda dan elko.
Idedasar pembuatan script remote shutdown komputer via SMS ini adalah kita buat script PHP untuk membaca sms yang masuk ke database MySQL nya Gammu. Jika isi smsnya berisi SHUTDOWN, maka lakukan proses shutdown. Karena saya menggunakan Windows XP, maka hanya dengan menggunakan command di shell atau prompt. view source print? 1. shutdown -s -f.
