Maitiro ekugadzira yakasimba yekugadzira simbi detector

Kana iwe uchida DIY uye ushingi, imwe yeakanakisa zviridzwa iwe zvaunogona kuva nazvo ndeye imba yesimbi detector. Nayo, hauzove chete nekunakidzwa uchikwenya kumaruwa uchitsvaga "hupfumi hwakavanzika", asi zvakare unakirwe nekuunganidza ichi chishandiso nemaoko ako pachako uye uchitevera mashoma mashoma matanho. Kune izvi, kune nzira dzinoverengeka dzekuzviita, kunyange vamwe vachikurudzira kushandisa redhiyo yekare yausingashandise, asi mhedzisiro inowanikwa haizove yakanaka kwazvo.

Ichi chinyorwa chinopa imwe nyanzvi yesimbi detector nesimba rakakura iyo inokutendera iwe kuti uone zvidiki kana zvakadzika zvikamu zvesimbi. Izvo zvinokuponesa kubva mukudyara rakakosha huwandu hwemari mune yesimbi detector, iyo inogona kusiyana zvakanyanya mumutengo. Semuenzaniso, unogona kuwana zvakachipa kwazvo uye izvo zvinopa mhedzisiro yakaipa yeanosvika € 40 kusvika € 4800 mune zvimwe zvigadzirwa zvehunyanzvi.

Maitiro 1: yakagadzirwa nesimbi detector uchishandisa redhiyo

Zvinogona kuve zvakanaka kutsvaga simbi dzisiri kure zvakanyanya kana kunyangwe tarisa tambo mumadziro usati wachera uye kuwana kutyisa kwakanaka ...

Zvinhu zvinodiwa

ari zvinhu zvakachipa kwazvo uye iwe unogona kuvawana kumba:

• Portable radio bhatiri rinofambiswa rinotsigira AM frequency. Unogona kuva chero radio zvakachipa pane zvaungave nazvo pamba pasina kushandisa kana kuwana imwe. Haifanirwe kunge iri hombe dhiri ...
• Yakachipa inotakurika karukureta, hazvidiwe kuti ive nehunhu hunoshamisa.
• Adhesive tepi, inogona kuve inodzivirira kana yeAmerica. Izvo zvinongobatanidza izvo zvishandiso.
• Tsvimbo refu, yakadai semopu, mutsvairo, tsvimbo isina kushandiswa, danda, kana kana uchida, a chinjika pakureba kweaya anoshandiswa nevapendi.
• Zvimwe: kana iwe uchida kuzvigadzirisa pane zvaunoda, unogona kuzvishongedza nebato rakapetwa, kana chero chaunoda.

Nhanho-nhanho kuvaka

Paunenge uchinge uine zvese zvinhu, kuvaka kwacho kuri nyore kutevera matanho aya:

1. Iyo emitter emitter inoshandiswa ichave iyo Calculator. Kana yakabatana, inoburitsa masaisai ayo achadhumhana nesimbi uye inoita kuti redhiyo igadzirirwe AM kurira zvakasiyana kana wawana simbi. Naizvozvo, iwe unofanirwa kunama zvese zviri zviviri pamwechete uye nenzira yekuti iwe ungavabatidza nyore.
2. Kana uchinge waiswa pamwe chete, unofanirwa kuona kuti iyo redhiyo iri pahoriyamu izere saka iwe unogona kunzwa oscillations zvakanaka. Kana ikabata chero simbi, ruzha rwayo ruchange rwusingakwidze zvakanyanya, saka zvakanak kuzviita munzvimbo yakanyarara.
3. Iwe unofanira Ita chokwadi kuti kana iwe uchivhara mu Calculator pane kupindira pawairesi. Ndicho chikonzero nei vachifanira kuve vari padhuze padhuze pamwe uye vakanyatsogadziriswa neanamatira tepi. Edza izvi nekuunza chinhu chesimbi padyo uye nekuona kuti ruzha rwunoitwa newairesi rwunoshandurwa sei, ndizvo zvinova zvinoitika zvinoitika kana uchinge watarisa mumunda
4. Pakupedzisira iwe unokwanisa wedzera tsvimbo refu yakasungirirwa pamidziyo miviri iyi kuti utsvage zvakasununguka pasina kukotama, kunyangwe kana uchizoshandisa iyo kumadziro iwe ungasarudza kuisiya isina tsvimbo ...

Maitiro 2: yakagadzirwa nesimbi detector uchishandisa Arduino

Es sarudzo yakanaka yekuenda kune zvakasikwa uye kutsvaga tsinga dzesimbi dzegoridhe padhuze nenzizi, kana kungo tsvaga zvinhu zvakaraswa nemumwe munhu kana kuviga imomo ...

Su mashandiro ari nyore. Iwe uchave sei uine capacitor uye inductor mune akateedzana, uye kana simbi ichisvika kune iyo inductor, uye ichichinja iyo magineti kukwana kweiyo inductor musimboti, zvichikonzera shanduko mukumisikidza uyezve shanduko mukushomeka mudunhu. Iko kushambadzira pamberi uye mushure meiyo inductor iri 180º kunze kwechikamu nemumwe, sekuColpitts oscillator. Iye achange ari mutariri wekugadzira yakajairika frequency kuitira kuti simbi ichichinje uye nenzwi rinonzwika rinorira.

La arduino bhodhi ichaita hanya nekugadzirisa iyo chiratidzo pachinzvimbo chekushandisa yechipiri dunhu kubhadhara iyo oscillation. Iyo Arduino bhodhi inochengeta yakamisikidzwa frequency uye ichienderera ichienzanisa nguva yekuisa yedetector wedunhu pamwe neakachengetwa frequency kuti aone kana paine misiyano (simbi inowanikwa).

Zvinhu zvinodiwa

Ndiro inofanira kushandiswa Arduino UNO Rev 3 uye Colpitts oscillator kuwedzera:

• Weed-whacker chishandiso (izvo zvakajairika trimmers) kana iwe unogona kuzviita iwe pachako bhokisi kuti ugadzire dunhu kana kuriprinta neako 3D purinda. Chinhu ichi chakanakira nekuti chine:
  • Bhatani remoto rinoshandiswa kumisikidza mutauri.
  • Bhatani rerutivi kumisikidza yakatarwa frequency.
  • Chikamu chebhatiri (3 AA mabhatiri) ine on / off switch.
  • Mutauri wekubereka matoni.
  • Mota ine maLED inosvetuka kana chimwe chinhu chikaonekwa.
  • Denderedzwa musoro uko kwekuisa iyo coil yetambo kune inductor yedunhu.
• Un potentiometer  kugadzirisa manzwiro ezwi.
• Una the coils inogadzirwa nematanho makumi maviri nematanhatu e26 AWG waya kutenderedza 26 ″ dhayamita spool.
• El redunhu (yakatsanangurwa muchikamu chinotevera) iyo yekutanga trimmer redunhu inofanirwa kutsiviwa neiyi imwe pane yakapetwa ndiro kana pcb.

Nhanho-nhanho kuvaka

Nekuvakwa kwayo:

Kuti uwane rumwe ruzivo nezve Arduino chirongwa, iwe unogona dhawunorodha ebook redu remahara.

1. Gadzira dunhu pamwe nebhodhi kutanga Arduino uye oscillator sekuonekwa mumufananidzo 1.
2. Ronga iyo Arduino bhodhi neizvi kodhi yeArduino IDE. Une kodhi mune yakataurwa-zvakanaka .ino paGitHub.
3. Tsiva iro redunhu rekutanga yesora-whacker yawakagadzira na. Inofanira kutaridzika semufananidzo 2.
4. Vhara chishandiso uye batanidza coil pazasi peichi chishandiso uye wobva wabatanidza kune dunhu sezvinoonekwa mumufananidzo 3.

Sekujekeserwa kwekupedzisira, taura kuti kana iwe uchimisa nayo kunzwisisika yakadzika, ichakwanisa kuona zvinhu zvakakura zvesimbi senge magaba esoda, nharembozha, maturusi ebasa, nezvimwewo, mukati memasentimita mashoma ekudzika. Asi kana iwe ukaisa kune iyo yakanyanya kunzwisisika, inogona kuona zvidiki simbi zvinhu senge mhete, screws kana mari pakadzika kumwechete. Kana iwe uchida, iwe unogona kuwedzera iyo nzvimbo yeiyo inductor yemagineti munda nekuwedzera iyezvino kuyerera kuburikidza nayo, ndiko kuti, kuwedzera iyo yekuisa voltage yeiyo oscillator kana kuwedzera iyo nhamba yekutenderera kwetambo yekoil ...

Maitiro 3: tenga simbi detector

Kana iwe usiri kuda kugadzira yako wega simbi detector, unogona tenga imwe paAmazon kana zvimwe zvitoro zvine hunyanzvi. Heano matatu ezvinokurudzirwa pamitengo mitatu yakasiyana, kuti uigadzirise kune homwe dzese:

• Yakachipa detector: na MD-9020C Unogona kutsvaga mari yekare, simbi, uye ese marudzi akavigwa simbi nemari shoma. Yakanaka kune vanotanga hobbyists avo vanoda chimwe chinhu kupfuura chakatsiga pakutsvaga kwavo uye icho chiri chehunhu hwakanaka. Iyo inokutendera iwe kugadzirisa kunzwisisika uye kudzika, uye kit yacho zvakare inosanganisira zvimwe zvishongedzo zvakaita sefoshoro, mabhatiri uye chinogadziriswa mubato.
• Pakati detector: the Garrett Ace 250 Iyo inyanzvi zvine hunyanzvi asi zvine mutengo une mutengo simbi detector, yakanakira kune vane ruzivo vane hobbyists kana kushandiswa kwehunyanzvi. Inogona kuona simbi uye zvakare magetsi waya. Ne 8-modhi gadziriso yekuenzanisa kunzwisisika uye kudzika kwaunoda kutsvaga
• Inodhura detector: Minelab Equinox 600 EQX11 Iyo ndeimwe yeakanakisa masimbi esimbi machena maunowana paAmazon. Iyo compact, isina kureruka uye inonyudza. Inogona kuona simbi diki kunyangwe iri chinhambwe chemamita matatu pakadzika.
• Wall detector: the Hapana zvigadzirwa zvakawanikwa. Inokutendera iwe kuona tambo kana pombi dzesimbi mumadziro kana pasi pevhu kuti usachere kana kuchera munzvimbo isina kukodzera pamba. Inoshanda uye inoshanda nebhatiri re9v. Zvakare, icharatidza chinhambwe chako chinosvika pane yako LCD skrini.

Zvino, kunyangwe iwe wakasarudza kuigadzira wega kana kuti iwe wakazvitenga, unogona kunakidzwa nekuenda kune zvakasikwa kuti uwane simbi pasi pevhu… Zvimwe uchawana chinonakidza!
