Dab tsi! ?? Lwm qhov Atari Punk Console tsim?

Tos tos tos tib neeg, qhov no txawv, cog lus.

Waaay rov qab rau xyoo 1982, Forrest Mims, Tus sau phau ntawv xov tooj cua Shack thiab Young Earth Creationist (yob qhov muag emoji) tshaj tawm cov phiaj xwm rau nws Stepped Tone Generator. Nws siv ob lub 555 timer chips (lossis 556 dual timer chip). Ib qho ntawm cov timers tau teeb tsa los ua tus khiav oscillator pub dawb, tso tawm qhov sib txawv ntawm qhov sib npaug ntawm lub teeb liab. Lwm lub sijhawm tau siv los ua astable lossis "one-shot" timer, lees txais qhov txhais thiab tom qab ntawd "nyob" rau qhov sib txawv ntawm lub sijhawm. Thaum lub teeb liab los ntawm thawj lub sijhawm tau txuas nrog tus pin ntawm lub sijhawm thib ob, qhov tso tawm ntawm lub sijhawm thib ob yuav dhau los ua qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm lub teeb liab uas yuav dhia nrawm raws li qhov dav ntawm cov mem tes ntawm lub sijhawm thib ob.

Yeej, koj tau txais kev lom zem me ntsis nrov nrov uas tuaj yeem tso tawm cov suab paj nruag kho kom zoo nkauj, ob lub pob qhov rooj tswj hwm tus thawj oscillator thiab lub sijhawm thib ob cuam tshuam nrog txhua lwm yam hauv kev nthuav, qhov txawv.

"Yog li qhov no txawv li cas?" koj nug.

Qhov no yog ua tau yam tsis muaj daim phiaj xwm txheej. Tsis tas li, muaj ob lub sijhawm thib ob.

Yog lawm Ob lub sijhawm thib ob. Peb 555 timer chips zoo li hauv daim duab.

Qhov ntawd txhais tau li cas yog lub suab nrov uas ob lub sijhawm thib ob tso tawm ib txwm cuam tshuam nrog ib leeg vim yog lej! Yog li koj tuaj yeem tau txais pob zeb-khoom polyphonic kev sib haum xeeb tawm ntawm qhov yooj yim Circuit Court. Polyphonic kev sib haum xeeb yog qhov nyuaj, tib neeg, Kuv caum qhov nthuav tawm-teb 1 volt rau octave qhov ntsuas hluav taws xob tswj oscillators rau ob peb xyoos ua ntej kuv tau txais qee yam uas kuv txaus siab.

Ntxiv nyiaj ntxiv! Koj tuaj yeem siv txoj haujlwm los ua lub hauv paus rau Atari Drone Console los ntawm kev tsim kom muaj ntau lub sijhawm thib ob raws li koj lub siab xav, thiab muaj cov phab ntsa loj heev ntawm lub suab nrov !!! Cov ntsiab lus hauv qib kawg.

Kauj Ruam 1: Peb Peb Chips Npaj Rau Kev Tawm Tsam

Thawj qhov peb yuav tsum tau ua yog npaj cov chips. Txhua ob-kab hauv kab-pob nti (zoo li cov no) muaj qhov me me los yog thais ntawm ib kawg ntawm nti. Thaum koj tso lub nti nrog lub thais ntsej muag tig (sab qaum teb deb ntawm koj?) Ob txhais ceg lossis tus lej tau suav nrog pib nrog rau sab laug sab saud, nqis mus rau hauv qab ntawm sab ntawd, txav mus los thiab tom qab ntawd nce mus rau lwm sab ntawm lub nti. Pins tau suav tus lej zoo li ntawd vim tias muaj qee yam ua nrog raj rov qab rau hauv ib hnub, thiab lawv tau puag ncig.

Yog li koj yuav ua li cas kom tau peb peb daim phiaj npaj rau kev sib ntaus yog khoov tus pin 1 thiab 8 rau pem hauv ntej, zoo li lawv tab tom npaj them ua ntej thiab ua rau cov yeeb ncuab nrog lawv cov ntxiab txaus.

Khoov tus pin 4 nce thiab hla sab saum toj ntawm lub nti.

Qhov ntawd yog nws. Ua tag nrho peb lub cim timer ib yam nkaus.

Kauj Ruam 2: Cov Electros Yog LIT… ic…. Electrolytic… nyeem ntxiv

Yog tias peb tuaj yeem muaj peev xwm zoo li yuav luag tag nrho daus las rau ib lub microchip thiab txiav txim siab kom tau txais cov qauv zoo nkauj niaj hnub ntawm 555, peb yuav tsis xav tau cov chunky loj electrolytic capacitor zoo li no. Kuv tus kheej, Kuv siv thawj tus neeg laib 555 chips, thiab lawv muaj lub npe tsis zoo rau kev nqus cov suab nrov mus rau lwm qhov kev sib txuas uas lawv tau txuas nrog. Yog li cov khoom siv hluav taws xob no (thiab cov neeg tawm tsam peb yuav siv tom qab) yuav tiv thaiv lwm cov khoom siv hluav taws xob los ntawm cov ntsiab lus me me.

Electrolytic capacitors yog polarized, lub ntsiab lus peb yuav tsum ib txwm nqes lawv kom raug. Yuav muaj kab txaij ntawm txhua lub capacitor (feem ntau yog lub teeb xim) nrog cov cim rho tawm hauv nws. Ntawd yog ceg "tsis zoo dua", thiab hauv qhov no, ceg yuav txuas rau tus pin 1 ntawm txhua 555 nti.

Qhov "zoo dua" txhais ceg ntawm lub capacitors yuav txuas rau tus pin 8 ntawm txhua tus nti.

Hom ntswj ob txhais ceg ntawm cov capacitors nyob ib ncig ntawm tus pin ntawm lub nti, nrog cov capacitors ntsaws kom huv hauv qab cov chips. Tawm ntawm lub tog raj kheej ntswj ib puag ncig tus pin 8 taw tes rau saum ntuj.

Kauj ruam 3: Tie the Reset High !!!

Pin plaub ntawm 555 nti yog tus pin rov pib dua. Nws rov pib dua, yog li peb xav kom nws tsis rov pib dua yog li peb khi nws siab !!! Koj paub, mus rau qhov twg qhov hluav taws xob zoo tuaj rau hauv Circuit Court.

"Tsawg" thiab "siab" yog cov lus hauv qhov xwm txheej no rau lub teeb liab uas yog qhov hluav taws xob siab (feem ntau tsawg kawg 2/3rds ntawm cov khoom siv hluav taws xob, tab sis daim duab sib txawv) lossis qis qis, ze rau hauv av. Los yog tsawg dua "siab" voltage, kuv twv. Qhov hais txog logic voltage yog tias nws tsis tas yuav muaj qhov tam sim no tom qab nws, yog li peb tuaj yeem siv tus tiv thaiv ntawm tus pin 4 thiab tus pin 8. Zoo, kuv twv yuav tsum muaj qee qhov tam sim no, tab sis tus nqi loj resistor yuav tsum ua haujlwm ib yam nkaus li cov hlua ncaj ncaj zoo li peb siv ntawm no.

Blah blah blah, ua qhov project zoo li no. Nrog tag nrho peb daim.

Kauj Ruam 4: Qhia Lub Cap ntawm Astable Multivibrator !

Thawj lub sijhawm yog oscillator, uas tseem hu ua astiv multivibrator los yog khiav dawb multivibrator.

Muaj lub npe, huh?

Nov yog thawj 555 lub sijhawm, thiab nws yuav txawv ntawm ob qho ntxiv. Thaum peb ua tiav nrog nws, peb yuav ua tib zoo teeb tsa nws ib sab kom peb nco tau tias nws yog leej twg.

Qhov txaus ntshai, qias neeg me me 10nF capacitor teeb tsa tus nqi uas tus oscillator yuav oscillate, ua ke nrog tus tiv thaiv (sib txawv resistor, potentiometer) peb yuav txuas hauv cov kauj ruam tom ntej.

Ib txhais ceg ntawm lub capacitor me txuas rau tus pin 1 ntawm lub nti. Tsis txhob txhawj, hom capacitor no tsis yog polarized, lawv tuaj yeem mus rau ob qho tib si.

Lwm ceg txuas rau tus pin 2 ntawm lub nti. Tab sis tsis txhob txiav tawm ceg ntawd! Nws mus txog txoj kev nyob ib puag ncig hauv qab 10uF capacitor, mus rau lwm sab ntawm lub nti, thiab txuas rau tus pin 6 ntawm lub sijhawm! Super weird, huh? Kuv twv nws tsis yog weird.

Kauj Ruam 5: Peb Thawj Potentiometer! Ib MILLION Ohms Koj Puas Ntseeg Nws?

Peb qhov loj tshaj!

Kuv txoj kev tsim kho siv qhov loj tshaj plaws los ua lub hauv paus ntawm kev siv hluav taws xob. Yog li peb thawj zaug me ntsis ntawm cov khoom siv hluav taws xob tau txais qee yam los dai rau, txias huh?

Ua ntej, peb yuav txuas 1K tus neeg tawm tsam mus rau nruab nrab txhais ceg ntawm lub zog, nrog tus tiv thaiv ceg ncab mus rau "sab qis" ntawm lub zog.

Lwm ceg ntawm 1K resistor txuas rau tus pin 6 ntawm 555 timer nti. Kuv tabtom siv cov tuab tuab-legged 1K resistors, uas ua rau lub cev ruaj khov zoo nkauj. Yog tias txhua yam koj tau txais yog cov yoj me me ua rau cov neeg tawm tsam, qhov no tseem yuav ua haujlwm tau zoo, tsuas yog qaug zog. Nws yuav muaj zog ntxiv rau qib tom ntej!

Tsuas muaj ib kauj ruam ntxiv! Txiav me ntsis ntawm txoj cai ntev kom ncab los ntawm "sab qis" ntawm lub zog ntsuas mus rau tus pin 7 ntawm 555 lub sijhawm timer nti. Solder qhov ntawd thiab peb zoo mus!

Yog tias koj txuas +9 rau +12V mus rau qhov kawg ntawm 220 ohm resistor thiab txuas tus pin 1 rau hauv av, koj yuav tuaj yeem txuas tus neeg hais lus rau tus pin 3 ntawm 555 thiab hnov lub suab! Yay koj thawj synth!*

*Kuv paub tseeb tias qhov no tsis yog koj thawj synth, thiab nws tsis yog synth, nws tsuas yog oscillator LOL: P

Kauj Ruam 8: Txais Lwm Tus Ob Rascals !

Okay, tso tseg lub sijhawm uas koj nyuam qhuav ua haujlwm. Tus txiv leej tub ntawd yog qhov ua tiav.

Koj yuav xav tau ob lub dab me me tsis zoo, muaj nuj nqis ntawm 100nF thiab 47nF. Cov txiaj ntsig no tsis yog txhua yam tseem ceeb - txhua yam tsawg dua 1uF (1uF zoo ib yam li 1, 000nF) thiab ntau dua 10nF yuav ua haujlwm. Thiab ua ob lub peev xwm sib txawv qhov tseem ceeb los ua kom txoj haujlwm zoo dua.

Anywhooo, txuas ib txhais ceg ntawm txhua lub tshuab hluav taws xob rau tus pin 1 ntawm txhua 555 nti.

Txuas lwm ceg ntawm txhua tus capacitor rau tus pin 6 thiab 7 ntawm 555 nti. Kuv paub hauv daim duab kawg ntawm cov kauj ruam no lub capacitor zoo li nws txuas nrog tus pin 8 hloov tus pin 1, tab sis nws yeej txuas nrog tus pin 1.

Kuj ceeb tias, ob tus menyuam timer me no yuav luag tiav lawm! Lawv tsuas xav tau resistors…. VARIABLE resistors! Ay-Kay-Ay potentiometers.

Kauj Ruam 9: Npaj Koj Lub Hau Npaj

Nqa koj tus kheej ob (2) 1M lub zog ntsuas. Txuas 220 ohm resistor rau txhua tus ntawm lawv ib yam li qhia. Saib, sab "qis" ntawm cov hwj huam no yuav txuas nrog rau + lub zog (dhau ntawm 220 ohm resistor ntawm chav kawm), thiab qhov no yog txoj hauv kev yooj yim kom tau txais lub zog ntawd mus rau hauv Circuit Court.

Kauj ruam 10 yuav tshuab koj lub siab!

Kauj Ruam 10: Nco ntsoov Ua Qhov Cuab Yeej Coj txawv no Ob zaug

Yog lawm, ntawm no peb yuav nyob tus pin 8 ntawm lub sijhawm nyob ntawm nruab nrab txhais ceg ntawm lub zog. Qhov "siab" sab ceg ntawm lub hwj chim zoo li haum haum ntawm tus pin 6 thiab 7, cov pins uas muaj cov tshuaj tiv thaiv kab laug sab soldered rau ob ntawm lawv.

Tam sim no cov timers tau ua tiav! Tsuas nco ntsoov ua cov kauj ruam no ob zaug.

Kauj Ruam 11: Khiav Ntau Lub Xov Tooj !

Nov yog qhov me me ntawm xaim xaim txuas rau "txhais" pins (pins 2) ntawm ob lub sijhawm thib ob mus rau "tso tawm" tus pin (tus pin 3) ntawm thawj lub sijhawm. Coj txawv txawv kuv tsis tau thaij duab ntawm thawj lub sijhawm, tab sis koj tuaj yeem siv koj lub tswv yim, thiab siv lwm qhov kawg ntawm cov xov hlau no (xiav yog tias koj muaj nws, muaj lwm yam xim yog tias koj tsis ua!) Rau tus pin 3 ntawm thawj timer.

Tsis txhob maj mus khoov cov zis thiab ua rau tus pin thoob plaws qhov chaw yog tias nws haum rau koj tsim. Kuv tsis tau khoov tus pin ntawm kuv tsuas yog vim kuv tsis xav piav qhia qhov kuv tau ua.

Kauj Ruam 13: Tov Khoom Number ONE

Tam sim no, nrog koj zoo siab, koj tau txais kev ua haujlwm Atari Punk Console x1.5! Tsuas yog koj tsis hnov nws.

Ntau APC tsim tsuas yog tso tus pin tso tawm ntawm lub sijhawm thib ob (tsuas yog ib qho) rau tus hais lus nrog lwm lub dav hlau hais lus txuas nrog hauv av. Peb muaj ob qhov txiaj ntsig txawm hais tias, uas yuav tsis zoo siab yog tias koj tsuas yog txuas ob qho tib si rau tus hais lus lossis lwm yam suab tawm tswv yim txuas. Lawv mam sib ntaus. Zoo li, them nyiaj rau ib leeg sim ua rau lwm tus cuam tshuam nrog lawv tus pas, nco ntsoov?

Qhov no yog qhov sib tov yooj yim tshaj plaws. Nws tau siv lub "siab" teeb liab los ntawm txhua qhov tso tawm, khiav nws los ntawm 1K resistor thiab tom qab ntawd muaj 1K resistor rau hauv av, faib qhov hluav taws xob (+9V lossis +12V) hauv ib nrab, uas tsis ua li cas vim 6V ncov-rau- ncov yog qhov txiaj ntsig zoo rau kev sib txuas hluav taws xob. Okay tej zaum 10V ncov mus rau qhov siab tshaj plaws yam tsis muaj DC qhov tsis zoo tab sis koj paub…..

Kauj Ruam 19: Ob Lub Tswv Yim Lom Zem Ntau

Pin 5 ntawm cov 555 timer chips yog tus "tswj" tus pin, uas zoo li yuav tsis siv yuav luag txhua lub sijhawm thaum tib neeg tsim kev sib txuas nrog 555 timers. Feem ntau tus pin 5 tsuas yog txuas rau hauv av los ntawm lub capacitor me me (10nF zoo li yog tus qauv) thiab tsis quav ntsej.

Kuv tab tom siv tus thawj 555 timers hauv kuv qhov kev tsim, uas zoo siab heev kom muaj tus pin 5 sab laug ntab, tawm mus rau saum huab cua, nrog qhov ntsuas hluav taws xob ib puag ncig thiab hluav taws xob zoo li qub nyob ib puag ncig nws hauv qhov tsis meej pem ntawm cov xim thiab lub teeb ……….

… xijpeem, tej zaum qee qhov zoo nkauj niaj hnub CMOS 555s yuav tsis nyiam kom lawv tswj tus pin dai rau hauv qhov chaw. Yog li ntawd txuas lawv rau hauv av los ntawm 10nF lub tshuab hluav taws xob lossis (qhov no yog txoj kev lom zem dua) siv tom qab ntawd tswj kev nkag hluav taws xob !!!

Koj tuaj yeem siv qhov hluav taws xob los hloov lub suab ntawm peb lub sijhawm nyob hauv txoj haujlwm no! Txuas tus tiv thaiv (10K txog 47K, qhov chaw nyob ntawd) rau tus pin 5, thiab txuas koj qhov kev tswj hluav taws xob mus rau lwm qhov kawg! Nrog rau qhov teeb tsa no, qhov siab dua txhais tau tias yog lub suab qis, tab sis peb tsis nyob tom qab

Nov yog lwm lub tswv yim. Yog tias koj tsim Fancy Tov Khoom rau txoj haujlwm no, koj tuaj yeem ntxiv ntau lub sijhawm thib ob raws li koj nyiam. Kaum rau. 32. 64. Tsis tas yuav txwv koj tus kheej rau lub hwj chim-ntawm-ob… cuaj, 27, 81… ua rau nws muaj hwj chim ntawm peb. Xijpeem, Fancy Tov Khoom koj tau tsim tuaj yeem lees txais qhov txwv tsis pub nkag los. Tsuas yog ntxiv 10K resistors rau tus pin 6 ntawm TL072, nrog rau 1uF capacitors, tau kawg, thiab tsim koj tus kheej Atari Punk WALL.
