Muna yin synthesizer da hannayenmu

Masu hada sinadarai waɗanda ake sayar da su a cikin shaguna na musamman sau da yawa suna da tsada sosai, kuma yawancinsu suna da abubuwan da ba kowa ke buƙata ba.

Idan kuna son adana kuɗi kuma kuna son kayan lantarki, kuna iya ƙoƙarin yin na gida hada-hada da hannuwanku.

Yadda ake yin synthesizer da hannuwanku

Akwai tsare-tsare da yawa don masana'antu mai haɗawa - daga mafi sauƙin analog zuwa dijital. A yau za ku koyi yadda ake yin polyphonic 48-key hada-hada kanka . Na'urar, wacce za a tattauna, za a gina ta ne bisa tushen guntu na CMOS 4060. Zai ba ka damar yin wasa cakulan da bayanin kula a cikin 4 lectures . Ana iya samun wannan ta hanyar amfani da janareta na mitar 12 don sautuna 12 da kuma na'urorin sautin 48 (ɗaya ga kowane maɓalli 48).

Abin da za a buƙata

Kayan aiki masu mahimmanci da kayan aiki

Kuna buƙatar kayan aikin masu zuwa:

• soldering baƙin ƙarfe;
• Saitin Screwdriver;
• saitin sukurori;
• sukudireba;
• mai zubar da ciki.

Dangane da kayan, kuna buƙatar samun adadin abubuwan da ake buƙata da sassa:

• azaman maɓalli, zaku iya amfani da makullin daga wani hada-hada wanda ba shi da tsari, ko daga abin wasan yara;
• allon da'irar da aka buga (farantin dielectric wanda ke tattare da da'irori na lantarki) na girman da ya dace;
• allo don maɓalli;
• cikakken saitin wayoyi da masu juyawa;
• ana iya yin akwati daga zanen filastik ko za ku iya ɗaukar sassa daga wanda ba ya aiki hada-hada a;
• 2 masu magana da sauti;
• saitin abubuwan rediyo masu mahimmanci da microcircuits;
• amplifiers;
• shigarwar waje;
• samar da wutar lantarki 7805 (tsarin wutar lantarki; matsakaicin halin yanzu - 1.5 A, fitarwa - 5 V; tazarar ƙarfin shigarwa - har zuwa 40 volts).
• dsP ICs (microcontrollers) waɗanda ke ba ku damar amfani da ƙarin tasirin sauti.

Jerin abubuwan rediyo

Cikakken saitin abubuwan da suka dace na rediyo:

Tsari daya . Wannan ya haɗa da abubuwa masu zuwa:

• 4060N guntu (IC1-IC6) - 6 inji mai kwakwalwa.;
• mai gyara diode 1N4148 (D4-D39) - 36 inji mai kwakwalwa;
• capacitor 0.01 uF (C1-C12) - 12 inji mai kwakwalwa;
• resistor 10 kOhm (R1, R4, R7, R10, R 13, R16) - 6 inji mai kwakwalwa;
• trimmer resistor 10 kOhm (R2, R5, R8, R11, R14, R17) - 6 inji mai kwakwalwa;
• resistor 100 kΩ (R3, R6, R9, R12, R15, R18) - 6 inji mai kwakwalwa.

Tsarin na biyu . _ Abubuwan da ake buƙata:

• mai daidaita layin layi LM7805 (IC 1) - 1 pc.;
• mai gyara diode 1N4148 (D1-D4) - 4 inji mai kwakwalwa.
• capacitor 0.1 uF (C1) - 1 pc;
• electrolytic capacitor 470 uF (C2) - 1 pc.;
• electrolytic capacitor 220 uF (C3) - 1 pc.;
• resistor 330 Ohm (R1) - 1 pc.

Tsarin uku . Ya hada da:

• amplifier audio LM386 (IC1) - 1 pc.;
• capacitor 0.1 uF (C2) - 1 pc.;
• capacitor 0.05 uF (C1) - 1 pc.;
• electrolytic capacitor 10 uF (C4, C6) - 2 inji mai kwakwalwa;
• resistor 10 Ohm (R1) - 1 pc.

Mataki-mataki algorithm na ayyuka

1. Don tarawa da synthesizer , kuna buƙatar aiwatar da jerin matakai masu zuwa:
2. Hana ramukan hawa 12 akan maɓallan.
3. Shirya allo don madannai. Wajibi ne a yi alama ga kowane maɓalli, dangane da girman su, kuma sanya microcircuits daidai a kan allo.
4. Shirya allon da'ira da aka buga ta hanyar gyara abubuwan rediyo da kunna shi.
5. Haɗa allon madannai, allon kewayawa da bugu da lasifika biyu zuwa kasan harka, haɗa wayoyi masu mahimmanci zuwa duk abubuwa.
6. Shigar da madannai.
7. Zazzage ƙa'idar gStrings zuwa kwamfutar hannu ko wayoyin hannu. Zai ba ku damar yin waƙa da synthesizer zuwa daidai mitar. Tun daga hada-hada an sanye shi da mai rarraba mita, ya isa ya kunna kowane rubutu guda ɗaya, sauran kuma za a kunna ta atomatik.

9. Gyara murfin saman.

your hada-hada ya shirya!

Matsaloli masu yiwuwa da nuances

Kula da mahimman abubuwa masu zuwa:

1. A cikin sigar da aka gabatar, hada-hada yana amfani da kewayawa tare da sautin fitarwa shida da mita daga 130 zuwa 1975 Hz. Idan kuna son amfani da ƙarin maɓallai da octaves, kuna buƙatar canza adadin sautunan da mitoci.
2. Ga waɗanda suke buƙatar mafi sauƙi synth ba tare da polyphony ba, guntu ISM7555 zaɓi ne mai kyau.
3. A ƙananan juzu'i, LM386 amplifier na iya haifar da ɗan ƙaramar murɗawar sauti a wasu lokuta. Don guje wa wannan, zaku iya maye gurbin shi da wani nau'in amplifier na sitiriyo.

A ina zan iya siyan abubuwan da ake buƙata na rediyo?

Ana iya siyan su daga shagunan kan layi daban-daban, kamar kantin sayar da kayan lantarki na Ampero.

Yadda za a yi tafiya daga tsohon Soviet synthesizer fit ?

Ana iya amfani da tsoffin abubuwan rediyo, amma a wannan yanayin, bai kamata ku ƙidaya ingancin sauti mai kyau da ikon yin wasa ba cakulan .
