Timapanga synthesizer ndi manja athu

Zolumikiza zomwe zimagulitsidwa m'masitolo apadera nthawi zambiri zimakhala zodula, ndipo zambiri zimakhala ndi zinthu zomwe si aliyense amafunikira.

Ngati mukufuna kusunga ndalama komanso mumakonda zamagetsi, mutha kuyesa kupanga zodzikongoletsera synthesizer ndi manja anu omwe.

Momwe mungapangire synthesizer ndi manja anu

Pali njira zambiri zopangira ndi synthesizer - kuchokera pa analogi yosavuta kupita pa digito. Lero muphunzira kupanga makiyi a polyphonic 48 synthesizer wekha . Chipangizocho, chomwe chidzakambidwe, chidzamangidwa pamaziko a 4060 CMOS logic chip. Idzakulolani kusewera mabimbi ndi zolemba mu 4 octave . Izi zitha kutheka pogwiritsa ntchito ma 12 ma frequency jenereta a matani 12 ndi ma 48 toni jenereta (imodzi pa makiyi 48 aliwonse).

Zomwe zidzafunike

Zida zofunikira ndi zida

Mufunika zida zotsatirazi:

• chitsulo chowumba;
• Screwdriver Set;
• seti ya zomangira;
• zomangira;
• woboola.

Ponena za zida, muyenera kukhala ndi zigawo zingapo zofunika ndi magawo:

• ngati kiyibodi, mutha kugwiritsa ntchito makiyi ochokera kwa wina synthesizer zomwe ziri kunja kwa dongosolo, kapena kuchokera ku chidole cha mwana;
• bolodi losindikizidwa (mbale ya dielectric yomwe mabwalo amagetsi amagetsi alipo) ya kukula koyenera;
• bolodi la makiyi;
• mawaya athunthu ndi masiwichi;
• mlanduwu ukhoza kupangidwa kuchokera ku mapepala apulasitiki kapena mukhoza kutenga mbali kuchokera kwa osagwira ntchito synthesizer a;
• 2 zokamba mawu;
• seti ya zinthu zofunika wailesi ndi microcircuits;
• amplifiers;
• zolowetsa zakunja;
• magetsi 7805 (voltage stabilizer; pazipita panopa - 1.5 A, linanena bungwe - 5 V; athandizira voteji interval - mpaka 40 volts).
• dsP Ma IC (microcontrollers) omwe amakulolani kugwiritsa ntchito zowonjezera zomveka.

Mndandanda wazinthu zamawayilesi

Seti yathunthu yazinthu zofunikira pawailesi:

Chiwembu chimodzi . Izi zikuphatikizapo zinthu zotsatirazi:

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

Chiwembu chachiwiri . _ Zofunikira:

• rectifier diode 1N4148 (D1-D4) - 4 ma PC.
• 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.

Chiwembu chachitatu . Zimaphatikizapo:

• 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 ma PC.;
• resistor 10 Ohm (R1) - 1 pc.

Tsatane-tsatane algorithm ya zochita

1. Kusonkhana synthesizer , muyenera kuchita zingapo zotsatirazi:
2. Boolani mabowo 12 pa makiyiwo.
3. Konzani bolodi la kiyibodi. Ndikofunikira kupanga zolembera pa kiyi iliyonse, kutengera kukula kwake, ndikuyika ma microcircuits ofanana pa bolodi.
4. Konzani bolodi losindikizidwa pokonza zinthu za wailesi ndi ma switch pa izo.
5. Gwirizanitsani bolodi la kiyibodi, bolodi losindikizidwa ndi oyankhula awiri pansi pamlanduwo, kulumikiza mawaya ofunikira kuzinthu zonse.
6. Ikani kiyibodi.
7. Tsitsani pulogalamu ya gStrings pa tabuleti kapena pa smartphone yanu. Idzakulolani kuyimba synthesizer pafupipafupi koyenera. Kuyambira ku synthesizer ili ndi chogawa pafupipafupi, ndikokwanira kuyimba cholemba chilichonse, ndipo zina zonse zizingosinthidwa zokha.
8. Malo opanda kanthu pakati pa zigawo amatha kukhala nawo dsP IC microcontroller.
9. Konzani chophimba pamwamba.

Anu synthesizer zakonzeka!

Mavuto omwe angakhalepo ndi ma nuances

Samalani mfundo zofunika izi:

1. Mu mtundu womwe waperekedwa, synthesizer a amagwiritsa ntchito dera lokhala ndi kamvekedwe ka zisanu ndi chimodzi komanso ma frequency kuchokera 130 mpaka 1975 Hz. Ngati mukufuna kugwiritsa ntchito makiyi ambiri ndi ma octave, muyenera kusintha kuchuluka kwa ma toni ndi ma frequency.
2. Kwa iwo omwe amafunikira chosavuta synth popanda polyphony, chipangizo cha ISM7555 ndi njira yabwino.
3. Pama voliyumu otsika, amplifier ya LM386 nthawi zina imatha kusokoneza pang'ono. Kuti mupewe izi, mutha kuyisintha ndi mtundu wina wa stereo amplifier.

FAQ (mafunso omwe amafunsidwa kawirikawiri)

Kodi ndingagule kuti zinthu zofunika pawailesi?

Atha kugulidwa m'masitolo osiyanasiyana apaintaneti, monga sitolo yamagetsi ya Ampero.

Will amazungulira kuchokera ku Soviet wakale kuphatikiza synthesizer ?

Zinthu zakale zamawayilesi zimatha kugwiritsidwa ntchito, koma pakadali pano, simuyenera kudalira phokoso labwino komanso luso losewera mabimbi .
Kanema pa mutuwu

Kuphatikizidwa

Zitha kuwoneka kwa wina ngati kupanga zodzikongoletsera kunyumba synthesizer sikophweka, koma iyi ndi njira yosangalatsa kwambiri. Ndipo pamene zolemba zoyamba zikumveka pa chida ichi, mudzamvetsetsa kuti zoyesayesa zonse sizinapite pachabe!
