Yog li, thawj qhov teeb meem koj ntsib yog lub teeb liab tsis zoo. Thiab vim li cas rau qhov no tuaj yeem yog dab tsi! Ntoo, vaj tse, nyob deb ntawm ib qho taw tes mus rau lwm qhov. Tib txoj hauv kev tawm hauv qhov no yog kom nthuav dav lub teeb liab, piv txwv li, nrog lub kav hlau txais xov sab nraud.

Peb muab cov qauv tsim ntawm tus kav hlau txais xov yooj yim, pheej yig thiab txhim khu kev qha, uas tuaj yeem ua tau raws li hauv av!

Tus kav hlau txais xov nce yog li 8 dB (qhov tau txais lub teeb liab dhau los ua 10 npaug zog dua). Qhov no yog tib yam li cov kav hlau txais xov lag luam feem ntau siv rau tib lub hom phiaj muab tawm. Lub ntsiab yuav tsum tau yog hais tias qhov kev ncua deb ntawm lub resonator nyob rau hauv daim ntawv ntawm "copper tsom iav" mus rau lub reflective txheej ntawm CD (reflector) yuav tsum yog 15 hli. Tab sis thawj yam ua ntej…

Wi-Fi kav hlau txais xov los ntawm pob CD txuas nrog lub teeb liab receiver

Kauj Ruam 1. Kev tsim cov ntaub ntawv

Peb nqa cov ntim li ib txwm rau 25 CDs

Txiav tawm lub hauv paus axis ntawm qhov deb ntawm 18 mm

Nrog ib puag ncig cov ntaub ntawv peb ua slots rau txuas lub resonator

Nws yuav tsum zoo li no

Kauj Ruam 2. Ua ib lub resonator

Lub resonator tuaj yeem tsim los ntawm ib daim ntawm tooj liab hlau txog 25 cm ntev thiab 2.5 … 4 mm inch. Hauv peb qhov piv txwv, peb siv ib lub xaim nrog txoj kab uas hla ntawm 2.5 hli.

Yog hais tias cov hlau yog insulated, nws yuav tsum tau muab tshem tawm

Cov hlau yuav tsum tau khoov rau hauv daim ntawv ntawm square "iav" kom qhov kev ncua deb ntawm lub hauv paus axes ntawm lub opposite sab ntawm txhua square yog 30 … 31 hli.

Peb khoov, nruj me ntsis tswj qhov loj

Peb txuas ntxiv maj mam khoov cov hlau

Peb tau txais xws li "iav iav". Txheeb xyuas qhov loj me dua

solder kawg ntawm cov hlau thiab tin qhov chaw ntawm lub neej yav tom ntej kho ntawm coaxial cable

Solder lub cable

Kauj Ruam 3. Mounting lub resonator

Sim ntawm lub resonator. Qhov kev ncua deb ntawm lub hauv paus ntawm txhua lub ntsiab lus yuav tsum yog 16 hli

Kaw lub CD nrog ob tee kua nplaum, ua haujlwm sab

Peb thawb lub cable rau hauv lub qhov ntawm tus tuav thiab kho lub resonator nrog kua nplaum

Ob chav square ntawm resonator yuav tuav los ntawm cov kua nplaum

Peb kho lub cable los ntawm sab nraum qab

Kauj Ruam 4. Txuas lub kav hlau txais xov

Peb yuav qhia qhov kev sib txuas siv qhov piv txwv ntawm D-Link 900AP Wireless Access Point (WAP).

Txhua tus neeg uas muaj kev paub dhau los thiab muaj kev ntseeg siab rau nws tus kheej tuaj yeem tshem tawm cov kav hlau txais xov qub thiab muab ib qho tshiab. Cov neeg uas tsis paub meej ntawm lawv tus kheej tuaj yeem txuas lub kav hlau txais xov ntawm SMA connector.

Nws yuav tsum tau borne nyob rau hauv lub siab hais tias los ntawm "mus rau hauv" lub ntaus ntawv (tsuas yog los ntawm kev qhib rooj plaub, thiab txawm ntau npaum li ntawd, manipulating nyob rau hauv ib tug soldering hlau), koj yuav tau nyob rau hauv tag nrho cov luag hauj lwm rau kev puas tsuaj thiab nws tsis ua hauj lwm. Koj yuav tsum paub tseeb tias koj paub qhov twg thiab yuav ua li cas txuas lub kav hlau txais xov.

Peb qhib rooj plaub ntawm lub cuab yeej. Sab hauv yog PCMCIA daim npav nrog kav hlau txais xov

Ua tib zoo!!! Vim qhov kub ntawm cov hlau soldering, nyias conductors tuaj yeem tawm ntawm lub rooj tsavxwm

Npaj txhij. Lub zog kav hlau txais xov, txawm tias nws zoo li yooj yim, yuav ua rau koj xav tsis thoob

Tam sim no koj tuaj yeem tau txais Wi-Fi teeb liab qhov twg nws tawm ntawm cov lus nug ua ntej!

Tsis muaj tsawg nthuav cov lus nyob rau hauv qhov teeb meem tshiab ntawm lub magazine:

• Roj teeb noj qab haus huv thaum mus ncig yog qhov teeb meem rhiab heev. Tom qab tag nrho, kev ua si lossis yeeb yaj kiab tsis yog tsuas yog ua kom muaj kev lom zem, tab sis kuj noj roj teeb. Charging suitcase (tswvyim), tsim los recharge koj gadgets.

• Tsis siv hluav taws xob. Yuav ua li cas ua kom lub teb chaws romantic-style txoj kev teeb koj tus kheej los ntawm cov khoom seem hauv 5 feeb.

Nyeem tag nrho cov version ntawm qhov teeb meem tshiab, sau npe mus rau mini-magazine los ntawm kev xa ntawv, tau txais kev hloov tshiab rau peb blog ntawm Lifehacker ntawm RSS
