Picture of How to Make Indonesia's WajanBolic or PanciBolic (USB)
My third instructables! Now I'm gonna teach you all Indonesia's Wifi Antenna made of wok.

NOTE: I didn't invent this cool thing.

Step 1: Gather the parts!

Picture of Gather the parts!
What you need:

1. Extended USB cable (click here)
2. Wok or the cover of a saucepan. (I use the cover of saucepan, because it's lighter).
3. USB WiFi
4. 3" PVC pipe. You need at least 1m. (depending of your wok size)
5. 1.25" PVC pipe. You need just a little of it, at least 5" long. Cut the middle (like in the picture)
6. Doff for 3" pipe (doff=pipe cover, holed in the middle. One of them connect to 1.25" doff using screw)
7. Doff for 1.25" pipe (stick aluminium foil inside then hole in midle, the other don't need to be holed)
8. Aluminium foil
9. Drill

If you don't understand, see picture

wuih...wajanbolic mlebu instructables...
pokoke makyoosss..
bantu sundul ya gan.. :)

this is how to get the focal point http://www.satsig.net/focal-length-parabolic-dish.htm dont know y they didn't include thins in tho

Cool, how do you calculate the focal point? And whats a doff, haven't heard that term before.
doff = pipe cap
huang.wencong (author)  dan moulton7 years ago
To find the focal point, use : D2/(16*d)
where D is diameter and d is depth.
A doff is the cap of the PVC pipe. That's what you call it here in Indonesia.

please tell me how we count the focal point?
 The design is ingenious -- the way you've combined a parabolic antenna with a waveguide antenna is both stable and cheap! Well done.

However, I don't see why you have the 1.25'' pipe piece in there. What does it do? Wouldn't the design work just as well without that piece?
i think the small piece work as holder for the wifi modem

Millmore, i am not sure if it is have to be 1m, but i think you have to check the calculation detail about this equipment. There is standard calculation for this equipment including detail about the pipe length needed, i was read it some month a go. You may find at the link some where he gave.
But the bad news, standard calculation have been made in Indonesian language, you need a dictionary maybe :).

Saya butuh yang buat internetan gratis. Rumor kata orang, temen bisa pake sampai 500 kbps gratis, tanpa batas. Butuh yang itu. ___________________________________________________________ I need that for free internet. Rumor, peoples and friends said it can reach until 500 kbps, free without limit.

Juragan, tuh tutup panci diameter brapa yak?
There are several links on the web including the formula you need to calculate the focal point for the parabola. Have used a seive and similar to gain access to free internet services outside normal range of usb dongles and have also managed to link across our local park between laptops (1km+) just try words like diy wifi antenna. good luck

do you know what WajanBolic or PanciBolic means? it means wok or pan lid bolic (parabolic counterpart) wok and pan lid is cheap and common in indonesia LOL
yay... Indonesia, Obama learned such stuffs while he was a kid here LoL Obama nyalon juga ga yah jadi presiden Indonesia?
bener tuh. dia SD dimana? agak lupa juga nih tapi yang gw tahu masih di jakarta kan?
nyalon jadi presiden indonesia? maksudnya? jadi tukang salon gitu? lol

setuju! keren juga nih...
perasaan gw cuma pernah liat comment inggris dan sekarang indonesia di instructibles ini... yay! cool!

Agree! it's cool
i only see english and now indonesia comments in this instructibles... yay! cool!

It's too bad you couldnt probably get a wifi connection with an ipod using this.. Im confused. Is this a Wifi range booster and a Wifi Pickup range boost? I know some devices allow external antennas for long-range pick up.. But not ipods!
I have used succesfully a sieve for a thing like this... Without measuring anything at all, we did manage to get an incrased signal while lying on anchor i a bay at a beautiful tropical location.

is a wifi max ok to use as the wifi thing

Are you sure you need 1m of 3" pipe? Your picture shows about 30cm. Step 3 is a little vague. How long should the foil and non-foil sections be? Is the 1.25" pipe there to hold the USB stick in place? If so, how does it do that? Thanks Martin

Greetings, How about some descriptive information in the introduction on what this thing is. What is the range? Anyone have a link on this? I can usually find anything in wikipedia, but can't find this. Thanks

WOW!!! Thanks everyone!!! My Instructable IS popular.....
Very nice way to mount a collector to a dish. I would wonder about the way the adapter is mounted though, the distance into the 3 inch tube that the adapter is placed can change the performance. At least that is what I found on a tube I built out of a fire extinguisher measuring about 3 inches in diameter. At first I had placed my adapter all the way in, like you did here, with just the connector outside of the tube, but I found that I got a better signal by pulling the adapter most of the way out. More info here: Wireless Internet Cantenna Wrapping PVC in foil is a good idea, I use a similar approach on the cone of my last wi-fi antenna: Conetenna I would expect the PVC to have no reduction in signal. The collector you built will probably cover a larger dish, I've heard from some really picky designer types that the outer edge of a parabolic dish shouldn't be counted on for much of a signal, so if you can find a reflector that extends a bit beyond what the collector is covering, the better. I would recommend combining your PVC collector with this: Parabolic Reflector
Uber Cool... Time for wifi hacks... LOL

*Keren banget... waktunya nyolong wifi gratisan, hahaha*

May I ask, can the signal/radio waves pass thru the PVC, as it shown here its inside the PVC and theres no metallic or foil inside to reflect thru the saucepan lid/wok. Can you enlighten me. I like to work on this. thanks in advance:)
What is the difference between a single USB wi-fi and this thing?
huang.wencong (author)  electrophobia7 years ago
Of course there is a big difference. This has higher gain.
so here is your five stars.. Great instructable..
