I-Homemade Inja ye-Ultrasonic Scan
UDater - Inja yenja ye-Ultrasonic, umdwebo kanye nencazelo yedivayisi. Sawubona izivakashi zesayithi lethu. Kwesinye isikhathi kuyingozi enkulu ukuzulazula ezungeze i-alley emnyama yedolobha ebusuku, ngoba ngaphandle kwakho emgwaqweni kungahle kube yinja elahlekile (ngesinye isikhathi) noma noma yimuphi umzuzu kusuka ekhoneni elimnyama likwazi ukukuphonsa kuwe futhi ukuluma kakhulu. Kungenzeka ukusheshe ungene empini, kepha akunakwenzeka ukuthi uphume empini ngaphandle komonakalo nokulimala, ngakho-ke kukhona inketho engcono - i-Ultrasonic Dog Repeller. Izizathu ezilandelayo zabandakanyeka ekwenziweni kwale divayisi: Okokuqala, ngangivame ukuthola ukukhangisa izimboni zezimboni-ov ekukhiqizweni okukhulu kwesiShayina, kanti okwesibili, kumasayithi amaningi "aqoqiwe" kwezinja eziqoqiwe Udonsele ukunaka kwami.
Idivayisi inamamitha ayi-13 kanye nethonya eliphakeme ezinjeni ezizokuluma. Njengoba sekushiwo, kusuka ezinhlelweni eziningi zokuqonda kwe-ultrasound kwezinja ezishicilelwe kwi-Intanethi, okuvame kakhulu kube yilokho okulandelayo.
Phezu kweBhodi - iPiezo Elevator SQ-340L. Kunganconywa ukusebenzisa i-ultrasonic MFC-200 ye-Ovestrist esikhundleni salokho, ukuba nengcindezi ephezulu ye-acoustic kuze kube ngu-85 DB, okusho uhla olukhulu.
I-Piezo Emitter ingatholwa kumakholomu, futhi kusukela ezikhulumeni zokuthi abantu babiza ama-pancake, ukusuka ebhokisini lomculo, kusuka kuma-wokubala, kusukela kuma-wokubala, kusukela kuma-wokubala, njalonjalo. Ibhokisi lokuhlanganisa i-repelter ye-ultrasonic bekulokhu kwenzeka kusuka ku-vhf ehlulekile yesiteshi somsakazo waseChina, ungasebenzisa noma yimuphi omunye umzimba osusondele, umsakazo, kanye nokunye, osayizi bawo futhi baholwa yintuthuko, yenza nomhlangano wedivayisi. Ngakwesokudla - Inkinobho ye-SB1, uma uchofoza lapho amandla avuliwe khona. I-Croon Throw Nutrition Battery, "Corundum", Into esemqoka yokuba ne-9 Volt Operating Voltage.
Isihloko ngesihloko: Kungenzeka yini ukubeka ukubeka upende? Inqubo yokususa upende nokusebenzisa uPutty
Ungasebenzisa amabhethri amabili e-lithium-ion kusuka kufoni ephathekayo ukuze kube lula. Ukubonakala kwemali eqoqwe kusuka ohlangothini lwengxenye kukhonjiswa esithombeni.
I-generator ecacisa ihlanganiswe kwi-microsmem yasekhaya, ibeka imvamisa oyidingayo, futhi i-transistor cascade ikhulisa. Izifo zesikhumba zingcono ukufaka izindawo, wonke ama-capacitors we-polar adinga ukulethwa ngogesi wama-volts ayi-15. Lesi sikhathi se-ultrasound sasetshenziswa kaningi ezinjeni futhi ngaso sonke isikhathi lapho wazibonakalisa kangcono kakhulu kunalokho obekulindelwe.
Lapho ukondliwa kwehliswa ku-3 volts, ikhwela le-texiac kungenzeka, elizwakala, futhi linama-volts ayi-9, imvamisa lenyuka futhi siyeka ukushicilela i-ultrasound. Ngokuvamile, le divayisi iyisikhali sokuzivikela esisebenzayo kusuka ezinjeni hhayi kuphela!
