Ikhaya apho: indlela yokudibanisa esi sixhobo sikhethekileyo

Ngoku ukuba uluhlu oludumileyo noluyimpumelelo IThe Big Bang Theory iphelile, ukuba uyayithanda, ngokuqinisekileyo usibonile isahluko apho uSheldon Cooper adlala khona esinye sezixhobo zomculo zingaqhelekanga ngezandla zakhe. Isixhobo esinqabileyo esikhupha isandi esingaqhelekanga ngokuhambisa nje izandla zethu phezu kwaso. Ewe, ukuba ibambe umdla wakho, kwesi sikhokelo siza kukufundisa indlela yokwakha eyakho Ikhaya apho kwaye sikubonisa ukuba isebenza njani.

Kuqala siza kubona ukuba yintoni i-Theremin kwaye yeyiphi imigaqo-siseko esekwe kuyo. isixhobo somculo esingaqhelekanga. Kwaye emva koko, siza kunika iinkcukacha ngamanyathelo okwakha i-Theremin elula kunye neyinkimbinkimbi, kuxhomekeke kwiimfuno zakho, kuba kunokuba yinto elula yokufuna ukwazi kwaye okona kufundiswa kulula kuya kwanela okanye ungafuna ukwenza pro ngakumbi kwaye Ndifuna ukuchitha iiyure ezimbalwa ndiziqhelanisa nezi ngoma zingaqhelekanga.

Yintoni i-Theremin?

I-theremin sisixhobo esaziwa ngexesha laso njenge etheróphone, thereminophone, termenvox okanye thereminvox. Sesinye sezixhobo zomculo zokuqala ze-elektroniki kwaye sayilwa eRashiya ngo-1920, nangona sasingenalo ilungelo lokushicilela de kwangowe-1928.

Iqukethe ii-eriyali ezimbini zesinyithi ezifumanisa indawo ekuyo izandla zalaphoOko kukuthi, kwimvumi eyidlalayo. Kuxhomekeke kufutshane, imiqondiso ye-acoustic esiyiva itshintshiwe enkosi kwii-oscillators ukulawula amaza (ngesandla esinye) kunye nokuphakama okanye ivolumu yenye. Ngale ndlela uncuthu lwengoma luveliswa sisithethi. Ke ngoko, sisixhobo esilula.

Kancinci iye yathandwa kwaye ibandakanyiwe kwezinye izingoma zomculo bhanyabhanya ezinje ngeKhumbula, iintsuku ngaphandle koPapasho, Ultimatum eMhlabeni, uthotho olunjengokubulala kwabakwaMidsomer, njl. Kwaye njengoko benditshilo ekuqaleni, ikwabonakalisile nakwinyani njengakwichungechunge lweBig Bang Theory.

Kwaye ngoku, inokubakho enye ekhayeni lakho ...

Usebenza njani?

Los imigaqo-siseko esekwe kuyo zilula. Sinesekethe esenziwe kunye nee-oscillator zethu, ii-resistors kunye ne-capacitors ezixhotyiswe ngumthombo okanye ibhetri. Akukho mfuneko yokuba siyichukumise, kuba ulawulo lusekwe kukuphazamiseka kwawo nawuphi na umzimba, kule meko isandla sethu, kunye nezixhobo zerediyo eziveliswa sisixhobo. Kwesinye sezikimu esizicebisayo, eyokuqala yazo, ayisekelwanga kwiRF, kodwa ekukhanyeni kombulelo kumfoto, kodwa umgaqo uyafana. Kumzekelo wesibini siwusekele kwi-RF.

Ewe, ukushwankathela, sinako oko Ukujikeleza kwesekethe ukuvelisa okanye ukungcangcazela kweliza lombane, into enomdla ekufundeni ukuba unayo i-oscilloscope edityaniswe kwimveliso yale sekethe kwaye ubone ukuba kwenzeka ntoni ngotshintsho lwesandla. Ukuba unethuba lokulijonga, uya kubona ukuba xa ususa isandla sakho isantya samaza siyahluka, sivelisa ingxolo kwisithethi esisibeke kwimveliso.

Oko kuyasivumela ukuqonda oku kwahlukileyo ngendlebe zethu esinokubona kwiscreen sesixhobo esifana ne-oscilloscope. Umfanekiso ongaphambili ubonakalisa ukuba isandla sakha njani i-capacitor nge-eriyali xa sisondela kuyo, kwaye ngokuxhomekeka kufutshane okanye kumgama, umqondiso uya kwahluka ngokungathi ingalo yethu yayiqhagamshelwe kunxibelelwano lomhlaba (GND).

Njengoko besesitshilo, ezinye theremin ziye I-eriyali ephindwe kabini, enye ilawula ivolumu kwaye enye ikhutshwa ngaphandle. Kodwa kwimeko yokusekwa kokukhanya, inye kuphela indlela yolawulo kunye nefotoresist eguqula isandi. Kwiprojekthi yesibini, kukwakho ne-eriyali enye yokulawula isandi, kodwa kuyinyani ukuba ibandakanya ii-potentiometer ezimbini esinokuthi ngazo silungelelanise ivolumu ngesandla esinye kunye ne-pitch, oko kukuthi, ukuyenza ibe ninzi okanye ngaphantsi kabukhali.

Yakha inyathelo lakho ngenyathelo likaTherem:

Elula apho:

Wethu prototype elula Iya kusekelwa kwiprojekthi evela kwimagazini yedijithali Yenza. Into oya kuyidinga zezi zinto zilandelayo:

• Ibhodi yesonka okanye ibhodi yokubonisa, nangona ungayenza isigxina ngokuyihambisa ngebhodi yePCB.
• 9v ibhetri okanye unikezelo lwamandla kunye nalo mbane.
• Somlomo I-Ohms.
• I-IC 555
• Ukumelana nefoto ngu 5pK
• Ii-capacitors ezi-2 0.22μF (edityaniswe kuthotho) okanye i-0.47
• Capacitor yombane I-100μF (lumka xa uyibeka kuba ine-polarity)

Ukuyinyusa, ungasebenzisa ukulandela umzobo weseketheNgokudibanisa izinto ngale ndlela kwibhodi yesonka ungafumana ikhaya lakho, ngoluhlobo:

Ngoku kufuneka uyixhume kwiipali zebhetri ukuze qala ukusebenza, emva koko beka isandla sakho kwi -min kwaye ungaqala ngeengoma zakho ...

Kwinqanaba eliphezulu:

Nangona zisuka kwi-blog yoLwazi bayichaza njenge uyilo olulula lwe-theremin Kwaye kunjalo, siyichonge kwangaphambili ukuba yahlule kwimodeli yokuqala eyayilula noko. Kule projekthi uzakufuna ezi zinto zilandelayo:

• NAND IC CD4093
• Isikhulisi sokuSebenza IMicrosoftchip MCP602
• I-Condenser 1nF, enye i-4.7µF, kunye nee-capacitor ezi-2 ze-100pF
• Abaxhasi: I-6 ye-10KOhm, 1 ka-5.1K, 1 ka-6.8K
• 2 potentiometers Kaninzi "
• Radio athena
• Amandla uJack
• Umsindo weJack
• Ipayiti yelayisensi PCB for ngelotha okanye yesonka
• Iplastiki okanye ibhokisi yomthi yokudibanisa yonke into (ngokuzithandela). Ungazakhela ngokwakho ngemilinganiselo eyimfuneko ukuba uyafuna okanye uyiprinte kwi-3D.

Ngoku Sihlanganisa zonke izinto zethu ukulandela umzobo wesekethe olandelayo:

Ngendlela, ndincoma ukuba uhambe ngayo kuqala kwibhodi yesonka Ukuze ukwazi ukuvavanya ukusebenza kwayo, kuba ukuba uthatha isigqibo sokudibanisa zonke izinto emva koko zingasebenzi, kuya kuba nzima ngakumbi kuwe ukuba ususe abathengisi kwaye uphinde umisele isekethe.

Ekugqibeleni unako bona kwaye wonwabele isiphumo:
