Scanning 7-Segment
Since the output buffer of P1 can sink 20mA (each output pin, but maximum IOL for all outputs was limited at 80mA), thus we can use P1 to drive LED display directly. As shown in the circuit, Two common-anode 7-segment LEDs are connected to P1 with 180 Ohms current limiting resistor. Each segment of two LED are tied in parallel to P1. Q1 and Q2 are activated by logic low of P3.0 and P3.1, sourcing +5V to common anode pins. P3.4 read logic low if either S1 or S2 was pressed while scanning period have made.

DC Power Supplay
Electronic devices should be powered by direct current supply DC (direct current) which is stable in order to work properly. The battery or batteries is a source of DC power supply is best. But for applications that require greater power supply, the source of the battery is not enough. Sources of power supply is a source of alternating AC (alternating current) from power plants. This requires a power supply device that can change the AC into DC current.
Rangkaian Power Supplay
Now it should not need another effort to make good pwer supplay you do not need to look for op-amps, transistors and other components, because these circuits are packaged into a single fixed voltage regulator IC. Are now widely recognized as a component of 78XX series fixed positive voltage regulator and the 79XX series is a voltage regulator to remain negative. Even these components are usually already equipped with current limiting (current limiter) and also limiting the temperature (thermal shutdown). This component is only three pins, and by adding some components alone can be a series of power supply regulation was good.

It's just to note that the I C regulator circuit that can work, the input voltage must be greater than the output voltage regulator. Usually the difference voltage Vin to the recommended VM is in the component data sheet. Usage heat hink (Aluminum cooling) is recommended if these components are used to supply large currents. In the datas heet, these components can pass the maximum current reached 1 A.

Installasi XP di Notebook CQ40-324TU(Cara Baru)
ALHAMDULILLAH.Setelah beberapa kali mencoba akhirnnya bisa install xp di notbukku cq40-324tu.Berhubung compaq seri cq menggunakan HD sata maka harus dimasukkan driver sata kedalam installer xp (http://tinyurl.com/sata-ahci-controller-driver).Untuk cara instalasi driver sata kedalam installer xp(slipstream) bisa anda dapatkan diberbagai tutorial.Tidak seperti di banyak tutorial yang mengharuskan untuk mendowngrade bios atau menginstal patch audionya pada start up windows,ternyata cukup menginstal xp seperti biasanya(tak perlu downgrade BIOS)tentunya setelah di lakukan slipstream.XP yang saya gunakan adalah XP ice SP3.Setelah installasi selesai lakukan upgrade BIOS. BIOS yang saya gunakan adalah BIOS V F5.5. Setelah update bios selesai lakukan installasi driver-driver yang ada. Dwnload di sini(http://www.laptops-drivers.com/compaq/how-to-install-windows-xp-into-compaq-cq40-101tu.html)

Windows 7 Hack: Mengktifkan atau menonaktifkan atau Pindah Quick Launch Bar
Quick Launch bar telah melihat dua kasus yang ekstrim digunakan pada Windows XP dan Windows Vista. Beberapa mencintai Quick Launch dan beberapa tidak. Tapi Windows 7 memang memiliki yang lebih kompleks mengambil ini. Proses navigasi Quick Launch membutuhkan lebih dari sekedar klik mouse untuk mengaktifkan atau menonaktifkannya. Jadi bagaimana Anda melakukannya? Berikut ini adalah trik sederhana.
Mengaktifkan Quick Launch Bar
1. Klik kanan pada Windows 7 Taskbar, dan arahkan ke Toolbar item menu konteks, kemudian pilih New Toolbar.
2. Cukup copy dan paste kode ini di address bar
% SystemDrive% \ Users \% username% \ AppData \ Roaming \ Microsoft \ Internet Explorer \
3. Cari dan sorot folder Quick Launch, dan kemudian klik pada tombol Pilih Folder.
A Quick Launch Toolbar akan ditambahkan ke Windows Taskbar dekat dengan area pengumuman. Unlock Taskbar (klik kanan pada Taskbar dan hapus centang pada Lock the taskbar) untuk memindahkan Quick Launch Toolbar.
Pindahkan Quick Launch Button
Misalnya anda ingin memindahkan peluncuran cepat tombol ke kiri taskbar.
1. Membuka peniti semua program aplikasi dari Superbar dengan klik kanan pada masing-masing dan setiap ikon, lalu pilih membuka peniti program ini dari taskbar.
2. Pindahkan kedua perbatasan Quick Launch Toolbar untuk yang terjauh kiri, dan kemudian kembali-pin. Dan anda selesai.
[Opsional, seperti yang Anda tahu, Anda dapat mengklik kanan pada ruang kosong di dalam kawasan Toolbar Quick Launch, dan hapuskan tanda Tampilkan Judul untuk menghapus kata-kata Quick Launch, atau hapus centang Tampilkan Teks untuk menghapus label di sebelah dan ikon cara pintas dalam Quick Launch bar]
Nonaktifkan Quick Launch Bar
Yang sangat sederhana.
* Klik kanan pada Taskbar
* Pergi ke Toolbar
* Ncheck item menu Quick Launch.
Lagi pula, jika Anda tertarik untuk membaca lebih banyak Windows 7 fitur dan hacks, Anda harus baca 10 Top Windows 7 artikel. Hei kami juga memiliki banyak Windows 7 up-to-date cakupan untuk Anda. Saya yakin anda akan tidak ingin kehilangan mereka.
