Imba ipapo: maitiro ekuunganidza ichi chakasarudzika chiridzwa

Zvino sezvo yakakurumbira uye yakabudirira nhepfenyuro Iyo Big Bang Theory yapera, kana iwe uri fan of it, iwe zvirokwazvo waona chitsauko umo Sheldon Cooper anoridza chimwe chezviridzwa izvi zvisingazivikanwe zvemimhanzi nemaoko ake. Chishoma chisingawanzo chinoburitsa ruzha rwekungoshamisira nekungofambisa maoko edu pamusoro pacho. Zvakanaka, kana ikabata pfungwa dzako, mune ino gwara isu tinokudzidzisa iwe kuti ungavaka sei yako Kumba ikoko uye tinokuratidza kuti zvinoshanda sei.

Kutanga isu tichaona kuti chii chinonzi Theremin uye nemitemo yakatarwa. chiridzwa chisina kujairika. Uye mushure meizvozvo, isu tichaenda kududziro nhanho dzekuvaka iyo yakapusa Theremin uye neimwe yakaoma Theremin, zvinoenderana nezvinodiwa zvako, nekuti zvinogona kuve kungoda kuziva uye dzidziso yakapusa inokwana kana iwe ungangoda kuita pro yakawanda uye iwe unoda kushandisa maawa mashoma uchidzidzira neaya asinganzwisisike tunes.

Chii chinonzi Theremin?

A theremin mudziyo unozivikanwa zvakare munguva yawo se etheróphone, thereminophone, termenvox kana thereminvox. Icho chimwe chezviridzwa zvekutanga zvemagetsi zvemagetsi uye zvakagadzirwa muRussia muna 1920, kunyange hazvo yaive isina patent kusvika 1928. Muvambi wacho aive Léon Theremin, ndosaka zita rayo.

Inosanganisira maviri esimbi antennas ayo anoona hama chinzvimbo che maoko emaheremist, ndiko kuti, kwemuimbi ari kuridza. Zvichienderana nekuswedera padyo, iwo maacoustic masaisai atinonzwa anochinjwa nekutenda kuma oscillator kudzora kuwanda (neruoko rumwe) uye kukura kana vhoriyamu neimwe. Nenzira iyi mutinhimira unogadzirwa kuburikidza nemukurukuri. Naizvozvo, iri nyore mashandiro.

Zvishoma nezvishoma rave kufarirwa uye yakaverengerwa mune mamwe mafirimu nziyo dzakadai seYeukai, Mazuva asina tsoka, Ultimatum kuNyika, nhevedzano dzakadai seMidsomer kuuraya, nezvimwe. Uye sekutaura kwandamboita pakutanga, zvakaonekwawo mungano senge mumutambo weBig Bang Theory.

Uye zvino, panogona kunge paine mumwe mumba mako ...

Rinoshanda sei?

ari misimboti iyo yakavakirwa pairi zviri nyore. Isu tine dunhu rakagadzirwa neyedu oscillators, resistors uye ma capacitors anofambiswa neiyo sosi kana bhatiri. Hatidi kuzobata, nekuti kutonga kunoenderana nekukanganiswa kwechero muviri, mune ino ruoko rwedu, nemasaisai eredhiyo anogadzirwa nechiridzwa. Mune chimwe chehurongwa hwatinofunga, chekutanga chazvo, hachina kuvakirwa paRF, asi pachiedza nekutenda kune fotoresist, asi musimboti mumwe chete. Mumuenzaniso wechipiri isu takavakira paRF.

Zvakanaka, muchidimbu, tine izvozvo dunhu rinogadzira iyo oscillation kana kudengenyeka kwemagetsi emagetsi, chimwe chinhu chingave chinonakidza kudzidza kana iwe uine oscilloscope yakabatana nezvinobuda mudunhu rino uye uone zvinoitika nekuchinja kwemaoko. Kana iwe uine mukana wekutarisa, iwe uchaona kuti kana iwe uchifambisa ruoko rwako kumhanya kwemafungu kunosiyana, kuburitsa ruzha kuburikidza nemutauri watakaisa pakubuda.

Izvo zvinotibvumidza isu kubata uku kusiana nenzeve dzedu iyo yataigona kuona pachiratidziro chechiridzwa senge oscilloscope. Mufananidzo wapfuura unoratidza mashandisiro anoita ruoko capacitor neiyo antenna patinenge tichisvika pairi, uye zvichienderana nepedyo kana chinhambwe, chiratidzo chinosiyana sekunge ruoko rwedu rwakabatana nechunhu chepasi (GND).

Sezvandinotaura, vamwe theremin vane kanyanga kaviri, imwe inodzora vhoriyamu uye imwe yekushomeka. Asi mune iyo optics-yakavakirwa imwe pane imwe chete nzira yekutonga neyekumirisana neyekugadzirisa iyo inogadzirisa ruzha. Mune chirongwa chechipiri, kune zvakare imwechete antenna yekudzora ruzha, asi ichokwadi kuti inosanganisira maviri potentiometers atinogona nemaoko kugadzirisa vhoriyamu nerumwe ruoko uye iyo pani, ndiko kuti, kuti iite yakawanda kana kupinza zvishoma.

Vaka yako wega Theremin nhanho nhanho:

Zvakareruka ipapo:

Wedu yakapusa prototype Ichave yakavakirwa pane chirongwa kubva kumagazini yedigital Gadzira. Izvo zvauchazoda izvi zvinotevera zvinhu:

• Breadboard kana prototyping board, kunyangwe iwe uchigona zvakare kuigadzira zvachose nekuisa pasoda pabhodhi rePCB.
• 9v bhatiri kana magetsi magetsi neiyi voltage.
• Mutauriri 8 Ohms.
• IC 555
• Photoresistance by 5pK
• 2 capacitors 0.22μF (yakabatana mune akateedzana) kana 0.47
• Electrolytic capacitor 100μF (chenjera kana uchiisa sezvo iine polarity)

Kuti ukwire iyo, unogona kushandisa iyo inotevera dhayagiramu yedunhuNokubatanidza zvinhu nenzira iyi pabhobhodhi unogona kuwana imba yako ipapo, saizvozvo.

Zvino iwe unofanirwa kungoibatanidza kumatanda ebhatiri kuitira kuti tanga kushanda, wobva waisa ruoko rwako pane izvozvi uye unogona kutanga nenziyo dzako ...

Yepamberi ipapo:

Kunyangwe kubva ku Instructables blog vanoitsanangura se yakapusa theremin dhizaini Uye saka zvirizvo, isu takazvisarudzira mberi kuti zvisiyane kubva kune yekutanga modhi yaive yakati rebei. Nezve chirongwa ichi iwe unozoda zvinotevera zvinhu:

• NAND IC CD4093
• Anoshanda gudzazwi MCP602 Microchip
• Condenser 1nF, imwe 4.7µF, uye 2 ma capacitors e100pF
• Resistors: 6 pamusoro 10KOhm, 1 pamusoro 5.1K, 1 pamusoro 6.8K
• 2 potentiometers yegumi
• Radio athena
• Simba Jack
• Sravana Sameeralu Serial XNUMXth Audio Jack
• Rezinesi ndiro Pcb for soldering kana chingwa chebhodhi
• Plastiki kana bhokisi remapuranga kubatanidza zvese (kusarudza). Unogona kuzvivaka iwe nematanho anodiwa kana uchida kana kuprinta mu3D.

Iye zvino isu tinounganidza zvese zvinhu zvedu uchitevera unotevera wedhayagiramu

Nenzira, ndinokurudzira kuti iwe uikwire kutanga pabhodhi rechingwa kuitira kuti iwe ugone kuyedza mashandiro ayo, nekuti kana iwe ukafunga kusungisa zvinhu zvese uye zvikasashanda, zvinozonyanya kukuomera iwe kubvisa iwo ma solders uye kumisazve dunhu.
