*** Hloov kho 4/22/'21 ***

*** Kuv tau ntxiv cov phiaj xwm qhia pom tag nrho cov thaiv los pab tsim kho. ***

Kuv yuav tsis nkag mus rau qhov tsis txaus ntseeg ntawm qhov tob ntawm qhov tsim, kuv lub hom phiaj yog los qhia lwm qhov piv txwv ntawm kev tsim Arduino raws MIDI tus tswj yog tias koj tab tom tshawb fawb lub ncauj lus lossis xav txog kev tsim qee yam thiab sib sau tswv yim. Kuv daim ntawv thov yog qhov tshwj xeeb tshwj xeeb rau Kab 6 Pod 2.0, tab sis nrog qee qhov chaws tweaking tuaj yeem ua kom dav dua siv tau. Muaj ntau qhov kev ua suab paj nruag cuam tshuam nrog MIDI lub peev xwm uas teeb tsa lawv cov presets hauv txhab nyiaj ntawm 4. Kuv ntaus guitar hauv qhov kev pe hawm niaj hnub no. Lub tsev teev ntuj muaj tus Kab 6 Pod 2.0 tus qauv ua haujlwm uas tso rau hauv pem teb thiab tsis muaj ko taw hloov pauv hloov ua ntej lossis pedal los tswj ntim. Muaj ntau tus tswj hwm uas twb muaj lawm hauv khw. Behringer FCB1010 yog qhov kev daws teeb meem zoo txog $ 150 tab sis siv sijhawm ntau qhov chaw hauv pem teb ntau tshaj qhov kuv xav tau. Thiab dua li, qhov kev lom zem yog dab tsi? Kuv paub tias kuv yuav tsum sim thiab tsim ib qho. Thiab … Kuv tswj kom ua tiav!

Kauj Ruam 1: Cov Ntaub Ntawv Kho Mob Yooj Yim

Cov Ntaub Ntawv Kho Mob Yooj Yim
Cov Ntaub Ntawv Kho Mob Yooj Yim

Chassis: Kuv "rov npaj" a "ZvBox 160" HDMI tus hloov pauv uas tau raug tua. Kev tsim kho hlau khov kho zoo, yuav tsum muaj sia nyob zombie apocalypse. Gutted nws, tso tawm cov ntu, ua ntsuas. Tom qab ntawd kuv tsim cov ntawv sib xyaw ua ke daim qauv/daim ntawv lo rau pem hauv ntej hauv Photoshop. Kuv tau luam daim ntawv lo rau ntawm nplooj ntawv puv daim ntawv thiab ntxiv daim nplaum laminated los ua ke. Saib midi_con_faceplate.psd. Lub thawv loj yog 1.7 "H x 10.5" W x 4.75 "D (4.32 cm H x 26.67 cm W x 12.07 cm D)

Xws li: Arduino Mega 2560 clone ua los ntawm Sainsmart.

Zaub: Kingbright qauv DC08-11SRWA. Kuv tau teeb tsa nws thiab 220 tus tiv thaiv xav tau ntawm lub qhov me me uas tseem tau muab txoj hauv kev los txhawm rau hauv lub chassis.

Kev Hloov Taw: qhov kuv tau pw ib puag ncig. SPST ib ntus, ib txwm qhib. guitarpedalparts.com muaj 'em rau $ 3.

LEDs: Kuv muaj qee qhov xim ntsuab thiab Blinking Liab LEDs uas kuv tsis tuaj yeem txheeb xyuas qhov twg lawv tuaj ntawm, tab sis ib qho 3 tus pin ntau cathode bi-xim LED yuav ua haujlwm.

Muab cov hloov pauv: SPDT me me, kev ua yog ON-OFF- (ON). Mouser ib feem # 611-7107-001.

Cov zis tawm: Rean NYS2122 TS 1/4.

Pedal: passive 10k linear taper lauj kaub hom. Kuv siv Kab 6 EX 1; M Audio EX-P thiab Roland EV-5 xav tias tseem yuav ua haujlwm. Saib daim duab rau cov lus qhia luv luv ntawm lub tshuab hluav taws xob.

Resistors: 10K rau rub tawm ntawm cov hloov pauv (QTY: 8); 220 Ohm rau MIDI nkaus (Kuv siv 2, ib qho yuav txaus); 220 Ohm rau preset channel LEDs (QTY 8); 220 Ohm rau Kingsbright zaub (QTY: 8); 2.2K rau kev qhia pedal jack (QTY: 1).

Chassis mount DC jack. Mouser ib feem # 502-712A.

Hloov tshiab: Kuv tau suav tag nrho cov duab-j.webp

Cov hloov pauv taw qhia tias "A" txog "D" xaiv 4 qhov ua ntej hauv lub txhab nyiaj. Lwm qhov 2 ko taw hloov pauv nce thiab txo tus lej hauv txhab nyiaj. Thaum hloov cov tsev txhab nyiaj, qhov kawg siv lub khawm teeb tsa ua ntej sib xws LED teeb nrog cov xim sib txawv kom txog thaum koj xaiv xaiv ua ntej ntawm lub txhab nyiaj tshiab, lossis rov qab mus rau lub txhab nyiaj qub.

2 qhov hloov pauv ib ntus tso cai rau tus neeg siv muab MIDI channel thiab cov lej txuas ntxiv mus (CC). Tsuas yog CC 1, 2, 4 thiab 7 tuaj yeem xaiv (teeb tsa hauv Arduino code, tab sis tuaj yeem nthuav dav) tab sis lawv yog cov feem ntau siv. Muaj 9 lub tsev txhab nyiaj ntawm POD 2.0, tus tswj hwm nkag mus rau tag nrho 9 tab sis kuj suav nrog lub txhab nyiaj tshwj xeeb 10. 10-A toggles lub tuner rau thiab tawm, 10-B xaiv wah hom rau tus pedal. Tog twg los 10-C lossis10-D yuav tua wah thiab rov qab mus rau tus neeg siv muab tus lej CC.

Lub neej ntawd yog CC7 rau ntim. LED zaub qhia tus lej hauv tuam txhab nyiaj tam sim no, thiab qhia ib ntus ntawm MIDI channel thiab CC tus lej thaum ua haujlwm.

Kauj Ruam 3: Txoj Cai:

Nov yog cov cai. Kuv tau sim ua kom nws muaj kev sib koom thiab suav nrog ntau cov lus pom. Thov siv, rov siv dua, tsim txom lossis tsis meej pem raws li xav tau.

Koj yuav tsum suav nrog MIDI lub tsev qiv ntawv los ntawm FortySevenEffects ntawm github.com.

Kauj ruam 4: Nws yog

Thov koj xav tiv tauj kuv yog tias koj muaj lus nug. Kuv tsis muaj tus lej guru, tab sis kuv zoo siab muab cov lus qhia lossis tswv yim.
