Membuat Antena Omni 2.4GHZ

Antena omni memiliki pola radiasi horizontal yang menyebar ke segala arah alias 360 derajat, sehingga antena ini sering digunakan untuk koneksi point to multi point di sisi Access Point (AP)

Bahan-bahannya:
1. Paralon 1″ (panjang disesuaikan dengan jumleh elemen antena)
2. 2 buah dop paralon 1″
3. Kawat tembaga (NYA 1×2,5 mm2)
4. Female N-Connector
5. Baut dan mur 2 pasang
6. Pipa paralon diameter 1/2″ 2 buah( masing2 panjang 12 cm)
6. Busa sterofoam (dipotong silinder diameter sesuai diameter dalam pipa, jumlah sesuai panjang paralon)

Langkah Pembuatan
1.Kupas isolator pelindung di sepajang kawat tembaga dan buatlah segmen2 seperti ini. Buatlah lingkaran sebesar keliling dalam pipa untuk membuat pembatas antar segmen.
Satu segmen berjarak 3/4 lambda (3/4 panjang gelombang; untuk frekuensi 2,4 GHZ, 1 Lambda = -/+ 12,5 cm . Jarak antara N-Connector dan batas awal segmen pertama 1/2 lambda (posisinya nanti di bagian bawah antenna).
2. Pasang N-connector pada salah satu dop paralon

3. Pasang busa2 sterofoam pada kawat agar posisinya tetap berada di tengah bagian dalam pipa



Akhirnya siap juga elemen dalamnya !  
4. Masukkan kawat yang sudah diberi sterofoam ke dalam pipa dengan hati2


5. Solder kawat untuk bagian bawah (yang panjangnya 1/2 lambda) dengan konektor.




6. Pasang kedua dop paralonnya dan jadilah antena omni kita!

7. Untuk membuat klem antenna, potonglah pipa PVC diameter 1/2″, panaskan lalu di-press panjangnya kira2 12 cm. Lalu buatlah holder antena dengan pipa berdiameter 1″ (masing2 panjangnya 2 cm) lalu dipotong secara vertikal membentuk penampang seperti huruf C. Holder kemudian dipasang pada pipa yang telah di-press dengan baut.



8. Antenna omni siap beraksi!

How to install OS X Mountain Lion on your PC with Niresh

 
If you're interested in running Mac OS X, but you don't want to pay ridiculous prices for a normal Mac, then a Hackintosh just might be for you. Right now, the newest iteration of OS X is 10.8, known as Mountain Lion. In this guide, we'll show you how to install Mountain Lion on your PC with the newly released "Niresh" distro.

We've previously covered how to install Mountain Lion on a PC using tonymacx86's Unibeast tool, which requires you to have an existing Mac OS X installation. This usually means that you have to install Snow Leopard on your PC first, or find a real Mac. We've also covered how to install Mountain Lion on a PC using a "distro" like iAtkos, which allows you to jump straight to Mountain Lion. However, you can't set up iAtkos on a regular DVD, and iAtkos doesn't work with AMD or Atom processors. If you need either of these limitations to be inconvenient, then using the Niresh distro instead may be your best option.

*You MUST be at the ROOT user to make/save any changes. Linux users, your distribution will determine the location of your network config file which will need to be updated and saved in order for the changes to remain in effect after rebooting. Network cards are referred to as eth0, eth1, eth2, etc based on their position on the PCI bus.
*Special thanks to Gergely for the Linux commands!

SSH TUNNELING ON ANDROID

If you want to have a secure browsing environment or just want to access your home network securely without exposing extra services to the internet and without the mess that comes with setting up and maintaining a VPN server, ssh tunneling is your rescuer. In this post, I’ll tell you how to setup an ssh tunnel to your home network easily. Also look for some bonus tips at the end 

This article assumes that you have already installed and setup a ssh server (you can probably use openssh). Also, it assumes that the ssh server is accessible from the internet (i.e. you have appropriately forwarded the port on which ssh server is running). I’d also recommend that if you do not have a static IP for your home network, then sign up for a dynamic DNS service (I use dyndns.org) so that you can access your home network easily by using a domain name (e.g. myserver.dyndns.org) from outside.

Now, here is a step by step guide on what to do on your Android Phone (I’m doing this on a Nexus one but should be same for you as well):1. Install an app called “connectbot” from the android marketplace. It is a FREE ssh client for android.

1. Open it and add the IP (or dynamic domain name as suggested above) and the port on which ssh server is running to the bottom and connect.

2. Once connected, press the menu button and select the icon which says “Port Forwards”

3. On this screen you can configure the ports to be used for tunneling.

MUDAHNYA MEMBUAT ANTENASTAR BOLIC

MUDAHNYA MEMBUAT ANTENASTAR BOLIC
Pada dasarnya untuk meningkatkan jarak jangkauan wireless LAN diperlukanantenna eksternal dengan gain yang lebih tinggi dari antenna standard dimanasetiap antenna mempunyai fungsi penerima ataupun pemancar signal.Berdasarkan fungsi tersebut antenna juga terbagi dari beberapa tipe yangbiasa digunakan untuk wireless LAN seperti :
? Antena Omni
? Antena Sectoral
? Antena Solid Dish
? Antena Grid
? Antena Yagi

Antena Patch PanelNamun kita tidak akan membahas semua tipe antena yang disebutkan tetapikita akan mencoba membuat sebuah antenna dengan beberapa perpaduan antenatersebut.Kita akan mencoba membuat antenna dengan tipe yang baru, sebut saja
“STAR BOLIC” sepertinya nama itu cocok dengan antenna yang akan kita buat
sekarang dimana antenna ini adalah perpaduan antara Antenna Grid dan Antena
Solid Dish namun jika dibandingkan dengan harganya sangat relative murah “cocokuntuk pelajar” sehingga memicu kreatifitas kita.
