Qhov no tsis yog Mickey Mouse distortion pedal! Cov pedal no yog cov clone ntawm ib qho kuv nyiam cov nyom pedals los ntawm 80's… ProCo's RAT Distortion. Nws yog qhov yooj yim OpAmp kev sib tw pedal siv classic LM308N IC nti uas yog qhov yooj yim tsim rau cov uas siv tau nrog rab phom phom, muaj hnub so dawb, thiab nyiam pob zeb-n-yob. Cov txheej txheem peb tab tom siv tau tsim los ntawm Francisco Pena uas tau ua tiav txoj haujlwm zoo nrog rau qhov no thiab lwm yam kev tsim qauv ntawm Tonepad.com. (thov tsis txhob hloov kho daim duab kos duab kos duab tshwj tsis yog koj tau kev tso cai los ntawm tus sau. (thov txim Francisco !!)) Cov phiaj xwm thiab PCB muaj nyob hauv PDF daim ntawv ntawm TonePad.com raws li qhov txuas no, uas tseem muaj lub tsev qiv ntawv zoo ntawm lwm yam teebmeem pedal thiab guitar cuam tshuam txog cov haujlwm tsim los ntawm pib mus rau qib siab. Koj kuj tseem yuav xav tau PDF rau Off-Board Wiring rau xaim lub qhov tso tawm/tso tawm lub zog thiab lub zog rau tus ko taw. TonePad.com tseem nqa cov ntawv luam tawm uas tau npaj tseg los yuav yog tias koj tsis muaj sijhawm lossis siv zog los ua koj tus kheej. Cov PCBs ntawm tonepad.com tuaj nrog lub vijtsam luam tawm tivthaiv ib sab, tinned solder pawm thiab tseem muaj daim npog qhov ncauj - txhua yam rau tus nqi zoo nkauj zoo xav txog tus nqi ntawm cov khoom koj yuav tsum yuav los ua koj tus kheej! Kuv pom zoo mus rau qhov kev taw qhia no yog tias koj xav kom ze rau qhov yuam kev pub dawb tsim tau. Koj tuaj yeem yuav feem ntau (yog tsis yog txhua qhov) ntawm cov khoom los ntawm Small Bear Electronics uas muaj tus nqi tsim nyog zoo nkauj thiab yog tus txhawb nqa TonePad thiab ob peb lwm yam nkauj DIY project qhov chaw. (Kuj pom zoo!) Kuv tsim cov duab hauv Adobe Illustrator thiab tau ua rau nws muaj hauv qab no rau txhua tus uas xav siv nws. Nws yog PDF cov ntaub ntawv khaws tseg los ntawm Illustrator yog li nws tau kho tau yooj yim nrog cov duab nraaj software uas tuaj yeem qhib pdf's….. muaj kev lom zem nrog nws thiab mus qus. lub tswv yim nws tuaj yeem ua dab tsi.) Tam sim no cia li npaj rau Rat-n-Roll…..

Kauj ruam 1: Tau txais cov khoom…

Cov ntaub ntawv PDF muaj cov npe ntu nrog rau kev teeb tsa pawg thawj coj saib xyuas. Qhov no tsis yog qhov phiaj xwm RatShack yog li koj yuav tsum xaj online los ntawm Small Bear Electronics lossis lwm lub chaw muag khoom muaj npe nrov xws li Digikey, Mouser, lossis MCMinone yog tias koj tsis muaj hmoo txaus los nyob hauv ib lub nroog nrog cov khoom siv hluav taws xob zoo. Kuv siv cov yeeb yaj kiab tiv thaiv cov hlau tsis txhob siv cov yeeb yaj kiab carbon vim muaj qhov ua tau nruj dua (10% lossis 5% rau carbon vs. 1% hlau zaj duab xis ntug ntawm qhov ua yuam kev) thiab yog tias koj yuav cov khoom lag luam online koj tuaj yeem tau txais lawv hauv qhov zoo nkauj pheej yig. Koj tuaj yeem hla cov ntaub ntawv IC's thiab transistors online ntawm NTE txhawm rau nrhiav "generic" NTE version, uas feem ntau yooj yim mus nrhiav hauv zos. Audiophile hom ua ntsej muag thaum siv NTE ntu rau cov phiaj xwm siab xws li kev tsim kho lub tshuab ua kom tsis sib xws hauv ib feem tshwj xeeb tab sis rau cov phiaj xwm zoo li no kuv tsis tau muaj teeb meem txog tam sim no. Tsis tau hais nyob rau hauv cov txheej txheem tab sis xav tias kev paub yog: Txhua tus tiv thaiv yog 1/4 watt, txhua lub capacitors yuav tsum tau ntsuas rau 12 volts lossis siab dua. (a 12V.01uF capacitor thiab 50V.01uF zoo ib yam tsuas yog 50V tuaj yeem siv hluav taws xob ntau dua thiab yuav loj dua qhov loj me yog tias koj xav paub.) Ntxiv rau ntu uas teev hauv daim ntawv PDF, koj kuj yuav xav tau: - Qty. 3- 100K-A (Suab lossis Logarithmic (tib yam) Potentiometers- 17mm txoj kab uas hla haum zoo dua (ceev faj kom tsis txhob tau txais Kab Tawm Taper Pots … qhov sib txawv loj!)- 3PDT stomp hloov (Me Bear Elec, lossis Ebay)- 9V roj teeb ntsaws thiab roj teeb Clip,-LED thiab LED tuav (yog tias koj xav tau qhov ntsuas qhov xwm txheej) -1/4 "Stereo input jack-1/4" Mono input jack-22 Gauge stranded hookup wire (preferable 3 different colors)-9V "wall wort" fais fab mov (tus thawj coj hauv nruab nrab yog "-") (qhov no tuaj yeem khaws cia ib qho nyob ib puag ncig 500 milliamps lossis li ntawd)- cov khoom siv hluav taws xob txuas (poj niam, uas sib txuas rau lub txuas hluav taws xob)- Cov ntaub ntawv tsim nyog (nyiam cov hlau rau lub zog thiab tiv thaiv.) Txheeb xyuas lub vev xaib.. Hammond rooj plaub yog qhov nrov tshaj plaws. Kuv pom kuv tus kheej ntawm kuv tus neeg siv khoom siv hluav taws xob hauv ib cheeb tsam.* Hloov kho* Kuv zaum kawg rov qab mus rau tom khw Kuv pom lub tuam txhab thiab ntu # ntawm rooj plaub … Lub tuam txhab yog: LMB Heeger (lawv muaj lub vev xaib ib yam nkaus) thiab rooj plaub yog # MDC532 Lwm Cov Khoom Siv & Cov Cuab Yeej: Soldering hlau, Cuab Yeej, Laum/Dremel, Laum Khoom, Khaub Ncaws Hlau, Cov Ntim Yas, Hnab Hnab Roj Hmab, PCB etchant (Ferric Chloride), Multimeter (rau kev sim/daws teeb meem), thiab npias txias.

Kauj ruam 2: Etching lub Circuit Board …

Muaj ntau qhov qhia thiab qhia hauv web ntawm yuav ua li cas los xij cov laug cam siv cov txheej txheem hloov pauv toner yog li kuv yuav tsis nkag mus ntau yam ntawm no. Kuv tau pom kuv txoj kev sim thiab muaj tseeb yog li koj yuav tsum sim ua kom pom qhov ua haujlwm rau koj. Kuv siv "ntawv ci" ntawv los ntawm FedexOffice's (lawv khaws nws tom qab lub txee yog li koj yuav tau nug nws) thiab luam tawm los ntawm lawv cov khoos phis tawj nthuav qhia rau B & W Xerox Phaser 5500 lub tshuab luam ntawv. Txhua FedexOffice's muaj lub tshuab luam ntawv no nyob rau thaj tsam ntawd (tsawg kawg thaum lub sijhawm sau ntawv no) thiab nws ntog lub tsho dub hnyav ntawm lub toner zoo meej rau cov txheej txheem no. Cov tshuab luam ntawv (tshwj xeeb tshaj yog Canon's) yog qhov txaus ntshai rau qhov no yog li kuv ua raws li qhov ua haujlwm. Thaum koj muaj koj cov duab tsis zoo (thim rov qab) ces koj npaj tau hlau rau ntawm tooj liab. Kuv ib txwm ntxuav lub rooj tsavxwm nrog cov ntaub plaub zoo (00 lossis 000) thiab tom qab ntawd so nws nrog cawv ua ntej kuv pib ua kom tau cov nplaum zoo tshaj plaws rau lub tooj liab. (Hauv cov duab no kuv tab tom khawb ntau lub laug cam los siv hauv cov haujlwm tom ntej). Muab koj lub ntsej muag tso rau pem hauv ntej thiab nrog cov hlau teeb ze rau qhov siab tshaj plaws (paj rwb) teeb tsa (tsis muaj lub zog) tso cov hlau nyob hauv nruab nrab li ob peb feeb kom yaj lub toner. Qhov no yuav tsoo nws mus rau tooj liab thiab nres nws los ntawm zawv zawg ib ncig thaum koj pib hlau thiab siv lub zog ntau dua. Kuv feem ntau ua haujlwm nrog lub ntsiab lus ntawm cov hlau txav los ntawm lub hauv paus sab nraud, tig lub rooj tsavxwm thaum kuv mus. Cov txheej txheem feem ntau siv sijhawm tsuas yog 5 feeb ntawm khov hlau kom txog thaum nws npaj tau. Nrog daim ntawv no kuv tuaj yeem pom cov kab ntawv toner dhau los thaum nws yuav luag npaj txhij. Peb koj txaus siab tias koj tau tag nrho nws yaj tom qab ntawd cia nws txias rau ib pliag lossis ob feeb thiab tom qab ntawd muab pov rau hauv lub tais kub/dej sov kom cia daim ntawv tsau me ntsis. Thaum ntawv pib khawm kuv pib zaws nws kom maj mam loos nws kom txog thaum nws pib tev. Lub hom phiaj tam sim no yog tshem tawm txhua daim ntawv los ntawm cov tooj liab. Nws tsis yog ib qho tseem ceeb kom tshem tag nrho cov ntawv lo rau cov kab ntawv toner tsuas yog tsuav tsis muaj daim ntawv thaiv lub qhov lossis txuas ib yam dab tsi. Kuv siv tus txhuam hniav qub qub thiab hauv qab tus kais dej kom maj mam txhuam cov ntawv tawv tawv uas tseem nyob. Tom ntej no kuv qhuav lub rooj tsavxwm thiab hauv qab lub teeb pom kev zoo Kuv tshuaj xyuas cov cim rau pinholes lossis tshem tawm cov xim toner thiab siv Sharpie tus cim los sau rau hauv qhov khoob lossis ua yuam kev. Tam sim no nws tau npaj rau txhawm rau … Kuv nyiam kom sov kuv Ferric Chloride los ntawm kev tso kuv lub chav da dej hauv chav da dej ntawm lub qhov dej kub-lub nroog Yeiuxalees, qhov no yuav ua kom lub tooj liab tshem tawm lub sijhawm ntau heev. (Nrog Ferric Chloride nws yog WISE siv cov hnab looj tes vim tias nws yuav luag txhua yam nws kov tshwj xeeb tshaj yog tib neeg cov tawv nqaij.) Tso lub rooj tsavxwm tos ob peb feeb, tom qab ntawd ua rau cov tshuaj daws teeb meem los ntawm nws ncig nws thiab tom qab ntawd cia nws zaum sau ntau ntxiv. Qhib lub npias txias thiab haus dej thaum koj tseem tos. Rov ua dua kom txog thaum tag nrho cov tooj liab raug daws, lossis tsis haus npias, tom qab ntawd tshem lub rooj tsavxwm thiab tawm nrog dej txias. Txhawm rau tshem lub toner koj tuaj yeem siv Acetone lossis Lub Tsheb Nres kom huv tab sis kuv tsuas yog siv ntsuab 3M scotch ncoo thiab lub luj tshib roj. Voila! Tam sim no koj muaj lub rooj sib tham hauv Circuit Court koj tau ua txhua tus los ntawm koj tus kheej !! Txhua yam uas seem yog txhawm rau khawb qhov me me thiab koj npaj tau pib siv cov laug. Kuv pom zoo kom siv lub laum xovxwm (Dermel muaj qhov zoo) rau cov txheej txheem no, nws yuav txuag koj ntau lo lus foom uas zoo dua siv rau hauv kev ncaws pob ncaws pob.

Kauj Ruam 3: Kuv Nyiam Tus Kheej Ntawm Tus Kheej Thaum Sawv Ntxov ……

Nov yog qhov kuv nyiam tshaj. Ua raws cov txheej txheem ntawm PDF Kuv ib txwm pib nrog Resistors ua ntej. Yog tias koj tsis paub yuav ua li cas nyeem tus tiv thaiv Kuv pom zoo kom luam tawm daim duab tawm ntawm lub vev xaib rau kev siv yog li koj tuaj yeem khaws cov txiaj ntsig ncaj thiab tsis sib xyaw lawv thaum tsim. Koj tseem tuaj yeem teeb tsa koj Lub Digital Multimeter rau Ohms thiab ntsuas lawv tus kheej, yog tias koj cov neeg tiv taus 5% ua siab ntev ces qhov tsis kam rau 100 ohm resistor tuaj yeem yog 95 txog 105 Ohms thiab tseem nyob hauv qhov tshwj xeeb.

Tom ntej no kuv txav mus rau Diodes thiab Capacitors. Tam sim no tsuas yog ntws ib txoj hauv kev los ntawm Diode thiaj li saib cov lus qhia kom koj tsis txhob teeb nws rov qab. Ceramic thiab Film Capacitors tsis yog polarized yog li lawv tuaj yeem muag tau nyob rau hauv ib qho kev taw qhia tab sis Electrolytic Caps (puag ncig tuaj yeem saib ib qho) yog polarized yog li xyuas kom tseeb tias tau muab tso kom raug lossis lawv tuaj yeem tawg. (Feem ntau muaj kab txaij khiav mus rau sab ntawm lub poom nrog lub cim "-" uas sib haum rau qhov tsis zoo ntawm lub tshuab hluav taws xob. Daim phiaj xwm phiaj xwm phiaj xwm phiaj xwm ib txwm muaj "+" kos npe rau ntawm nws qhov chaw Zoo mus. Txawm hais tias tsis nyob ntawm cov npe khoom, Kuv yuav 8-Pin IC Socket rau LM308 yog li kuv tuaj yeem sib pauv nws nrog lwm cov Op-Amp chips tom qab yog tias kuv xav ua ib qho kev hloov pauv yam tsis tas yuav muag dab tsi. Koj tuaj yeem tau txais teeb tsa 2 ntawm RatShack rau.69 xees… ntu # 276-1995. Tom qab cov khoom siv tau xau ces ua ntej mus rau cov xov hlau. Kuv yuav peb pob ntawm 22 lub xov tooj cua ntawm RadioShack uas los hauv Dub, Liab, thiab Ntsuab yog li kuv tuaj yeem khaws txoj hauv kev zoo ib yam xim xim rau qhov ua pov thawj dag. Solder Cov Pots rau cov xov hlau tom ntej, ua tib zoo mloog qhov kev txiav txim (qhov no yog qhov sib txawv ntawm cov xov hlau uas pab tau. Kuv nyiam ntswj cov xaim zoo sib xws ua ke kom khaws cov khoom sib koom thiab ua kom lawv tawm ntawm txoj hauv kev. cov lauj kaub tau pom lub ntsej muag qis yog li nco ntsoov nco ntsoov thaum siv tshuaj txhuam.

Tam sim no peb yuav tsum txiav txim siab seb peb xav xaim lub tsheb kauj vab li cas rau lub zog thiab hla dhau. Cov Off-Board thaiv PDF muaj 6 qhov kev teeb tsa sib txawv nyob ntawm seb koj nyob tom qab. Yog tias koj tsuas tuaj yeem pom DPDT hloov koj yuav tsum tau siv ib qho ntawm cov txheej txheem nrog Millennium By-Pass teeb tsa uas xav tau ntxiv ntu thiab cais pawg thawj coj uas yuav noj ntau qhov chaw. Txoj kev nrawm tshaj plaws thiab yooj yim tshaj plaws yog kom tau 3 tus ncej muab pov pov tseg (3PDT) los ntawm Ebay (pheej yig tshaj) lossis lwm qhov chaw ntaus guitar hauv lub vev xaib. Nrog 3PDT hloov koj tuaj yeem xaim ib qho LED yam tsis muaj teeb meem ntawm kev ntxiv cov phiaj xwm sib cais nrog ByPass Circuit. Peb yuav siv Txoj Haujlwm Hluav Taws Xob Offboard 5 rau txoj haujlwm no. Qhov teeb tsa no yuav tso cai rau LED, roj teeb lub zog, thiab rau sab nraud 9V DC zog. Txiav txim siab qhov chaw zoo tshaj plaws ntawm koj rooj plaub rau cov tswv yim nkag thiab tso tawm. Kuv nyiam lawv nyob tom qab kom khaws cov hlua guitar tawm ntawm kuv txoj kev thaum ua si thiab rau rooj plaub no tsim nws muab rau kuv nrog qhov chaw nyob sab hauv. Siv lub caij nplooj ntoo hlav txhawm rau txhawm rau txhawm rau cim qhov nruab nrab ntawm lub qhov, qhov no yuav muab rau koj hauv nruab nrab thiab yuav ua kom lub qhov me ntsis los ntawm zawv zawg ib puag ncig thaum koj laum. Laum tawm cov qhov no thiab tseem lub qhov rau 3PDT hloov chaw, 3 Lub Hau, LED, thiab Sab Nraud txuas lub zog. Koj tuaj yeem tsim daim duab thuam ntawm koj cov ntaub ntawv thiab ua si ib puag ncig nrog kev tso chaw ntawm cov khoom ua ntej koj xyaum yog tias koj tsis paub meej txog qhov haum. Kuv tau siv qee cov ntawv ntsuas hlau nyias los ua cov khoom sib dhos rau PCB mount uas txuas rau rooj plaub ntawm lub lauj kaub nruab nrab kom tsis tas yuav ntxiv qhov ntxiv hauv rooj plaub. thiab cov txuas hluav taws xob raws li tau hais tseg hauv daim duab. Txheeb ob zaug txhua qhov kev ua haujlwm kom ntseeg tau tias lawv raug vim nws yooj yim los sib txuas cov xov hlau hauv txhua qhov kev ntxhov siab. Kuv tau teeb tsa txhua yam ib ntus rau hauv rooj plaub kom tau txais lub tswv yim ntawm qhov ntev ntawm cov xov hlau Kuv yuav xav tau los txhuam txhua lub jack thiab hloov ua ke. Thaum qhov kev ntsuas qhov ntsuas thiab cov xov hlau tau txiav kuv tau muab txhua yam sib nrug thiab muab nws tso ua ke. Kuv tawm ntawm cov xov hlau khiav mus rau 3PDT hloov me ntsis ntev li muab kuv tus kheej qee chav kom khiav lawv mus rau ob sab kom muaj chaw rau lub roj teeb clip nyob nruab nrab ntawm pawg thawj coj thiab hloov. Kuv siv cov yas yas nyias los cais cov roj teeb los ntawm cov kab hluav taws xob nthuav tawm los tiv thaiv los ntawm ib qho kev luv luv hauv qhov xwm txheej uas lawv tshwm sim kov ib leeg. Qhov yas tau khoov zoo li lub rooj sib txuas ntawm lub rooj sib txuas thiab txuas rau rooj plaub siv lub qhov drilled rau lub roj teeb clip uas yog mounted rau hauv qab ntawm rooj plaub.
