2. Lub tsev ua yeeb yam zoo nkauj marquee hom (yooj yim heev rau kev ua yeeb yam!)
3. LED siv tswj
4. Lub tsev qiv ntawv chord tag nrho ntawm thawj txoj haujlwm Ukulele chords (chord tus nqi thiab tus yam ntxwv)
5. Muaj peev xwm los qhia cov ntawv nyeem (ntsug) siv qhov tshwj xeeb 4 x 6 pixel cim teeb

Cov lus qhia no piav qhia txog daim ntawv ua tiav. Zaj dab neeg kev txhim kho tag nrho muaj nyob ntawm no, suav nrog qee qhov kev kawm (mob) ua yuam kev thiab cov lus qhia muaj txiaj ntsig vim li cas koj YUAV TSUM ua tiav koj thawj qhov kev tsim kom tiav (tsis muaj teeb meem dab tsi dab tsi tau txais). Koj yeej tsis paub txhua yam uas koj tsis paub tiag txog thaum koj mus txog qhov kawg (thiab tom qab ntawd koj tseem tsis tau paub!), Tab sis koj nyob nraum zoo dua thiab ntse dua rau kev tsim qauv tom ntej.

Kuv ua tus qauv ib ncig ntawm Grizzly Concert Ukulele cov khoom siv. Pib nrog cov khoom siv tshem tawm qhov kev txhawj xeeb txog lub cev ntawm uke (zoo, feem ntau), thiab tshem tawm feem ntau ntawm kev ua haujlwm zoo tiag tiag. Cov khoom siv no ua tiav zoo nkauj thiab tsis kim li hauv cov txheej txheem loj ntawm cov khoom (thiab tsis mob ntau vim tias koj yuav ua yuam kev).

Kauj Ruam 1: Npaj Hom Phiaj

Fretboard (lossis ntiv tes ntiv tes) suav nrog hauv qee cov khoom siv twb muaj cov khoom sib txuas ua ke. Qhov ntawd zoo/phem. Nws zoo li lub sijhawm txuag, tab sis hais txog kev teeb tsa lub laum qauv thiab tuav nws hauv qhov chaw thaum milling, nws mob me ntsis. Tom qab rhuav tshem ib qho uas tau muab rau hauv cov khoom siv, Kuv tau xaiv (zoo, Kuv tsis muaj kev xaiv dua li yuav lwm cov khoom siv) los yuav lub fretboard tshiab.

Thaum tsim lub fretboard, peb yuav tsum suav qhov nce hauv qhov tuab uas yuav tsum tau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhim kho PCB thiab cov LEDs (thiab tsis txhob hnov qab cov khoom siv tsis dhau), tab sis tsis ntau npaum li cov LEDs nyob deb dhau ntawm qhov chaw fretboard.

Cov ntawv luam tawm Circuit Board LED (PCB) tau tsim los ua cov txheej txheem yooj yim 2 txheej. Qhov no pab tau ntau nrog tes sib dhos ntawm cov hlua LED thiab muab qee yam khoom siv dag zog (nws yog fiberglass thiab epoxy) rau Ukulele caj dab. Kuv pib qhov txheej txheem hauv Dav dawb hau, tab sis tau xaus siv Altium Designer vim yog pawg tswj hwm qhov txwv me me. Altium schematic thiab PCB cov ntaub ntawv nyob ntawm no.

Cov khoom siv fretboard tsuas yog tuab 0.125 ntiv. Yog li, piv txwv tias yog 0.062 nti tuab PCB thiab tso cai ntxiv 0.062 nti rau LEDs, txhais tau tias peb yuav tau txiav tawm ntau (zoo li txhua yam) ntawm lub fretboard. Txhawm rau them nyiaj peb tuaj yeem txiav ib feem rau cov LEDs hauv lub fretboard nrog lub hnab ntim sib xws hauv lub caj dab rau PCB, lossis peb tuaj yeem hloov tag nrho cov fretboard (qhov kev xaiv kuv mus nrog) nrog cov ntawv tuab los ntawm Luther Mercantile International (LMII), uas yog 0.25 ntiv tes los pib.

TAB SIS, nco ntsoov tias koj tseem yuav tsum tau tshuab lub caj dab txhawm rau txhawm rau txhawm rau nce qhov tuab hauv cov fretboard. Lwm qhov txiaj ntsig koj tau txais yog tshuaj pleev ib ce, txij li tam sim no PCB tam sim no tau ua tiav sab hauv lub fretboard uas ua rau cov npoo yooj yim dua kom tiav (thiab saib zoo dua!) Thiab yooj yim milling lub caj dab.

Cov khoom siv engineering (tsis quav ntsej yog tias koj xav tau):

Los ntawm txoj kev, qhov no tsis cuam tshuam qhov nruj ntawm lub caj dab ntau npaum li cas. Cov khoom siv PCB yog qhov nruj dua li cov ntoo fretboard qub (Mahogany modulus: 10.6 GPa piv rau FR4 modulus: 24 GPa), ntxiv rau txij li thaum peb tab tom tsim Ukulele, tsis muaj qhov loj ntawm txoj hlua nruj uas tuaj yeem txwv tsis tau los yog warp) lub caj dab.

Ib qho kev txiav txim siab nthuav heev (uas kuv tej zaum tseem yuav tsum suav) yog qhov tshwm sim dhau qhov kub thiab txias. Feem ntau rau ntoo, sib npaug rau cov qoob loo, cov cua sov coefficient ntawm kev nthuav dav yog kwv yees li 3 x 10^-6/K, thiab rau FR4 nws yog 14 × 10^−6/K. Yog li, muaj qhov sib txawv tseem ceeb heev. Qhov kev txhawj xeeb yog qhov nro tau tsim nyob rau hauv lub caj dab raws li qhov kub txawv, uas nyob rau hauv lem de-tunes cov hlua. Qhov ntawd yog qee yam uas tuaj yeem raug them los ntawm kev thov txheej txheej zoo ib yam ntawm sab nraud ntawm qhov nruab nrab lossis los ntawm kev tau txais FR4 kom ze li sai tau rau qhov nruab nrab. Tab sis qhov ntawd yuav tshuav rau 2.0… Ib yam dab tsi los ua qauv thiab ntsuas.

Cov khoom siv hluav taws xob tau nyob hauv lub cev ntawm uke. Lub qhov raug txiav rau ntawm phab ntsa (tsis yog lub suab ntawv!) Ntawm UKE kom ua chav rau cov zaub thiab cov lus teb, ntxiv rau phaj nkag mus tuav Arduino Micro thiab muab kev nkag mus rau USB interface. Kev nkag mus rau phaj/tsim qauv thiab qhov chaw tuaj yeem zoo tuaj yeem ua kom USB txuas tau tawm hauv qhov chaw yooj yim dua, tab sis raws li nws sawv, nws tsis yog txhua yam phem, vim nws tsis yog txoj hauv kev thaum koj tab tom ua si.

Kev ntxiv cov xov hluav taws xob tuaj yeem ua tau yooj yim nrog rauj (nrog lub ntsej muag yas kom tsis txhob muaj menyuam). Tsuas yog tsis rauj hnyav heev. Yog tias koj tau sib phim cov xov hlau tsis zoo rau lub qhov, lawv yuav tsum nkag mus yam tsis muaj teeb meem ntau.

Yam uas koj yuav tsum tau saib rau yog txhawm rau txhawm rau qhov nyias nyias ntawm lub hnab tshos LED. Ntawm tus qauv, Kuv tau tso cai qee qhov LED hnab tshos (ze rau qhov kev ntxhov siab thib 12, qhov chaw tau nruj) kom nthuav dav mus rau qhov kev ntxhov siab. Qhov ntawd yog lub tswv yim tsis zoo, txij li qhov ntawd tsim qhov chaw tsis muaj zog uas yuav (thiab tau ua) tawg thaum cov xov hlau ntxig ntxig.

Kauj Ruam 14: Thov Daim Npog Qhov Ncauj thiab Thov Tiav Rau Ukulele

Npog daim fretboard (nws tsis ua tiav) thiab thaj chaw txuas ntawm tus choj thiab pib thov ua tiav.

Thaum npog thaj tsam ntawm tus choj, nyeem cov lus qhia nrog koj cov khoom siv, tom qab ntawv txheeb xyuas qhov ntsuas qhov ntev kom paub tseeb. Cov khoom siv kuv siv rau tus qauv siv qhov ntsuas ntsuas tsis raug thiab yog li muab qhov ntsuas tsis raug rau nrhiav tus choj (tab sis nws tau muaj ntawv ceeb toom los tshuaj xyuas lub vev xaib rau cov lus qhia tshiab kawg!). Kuv lub plab hais rau kuv tias nws tsis yog lawm, tab sis kuv tau dig muag lees txais txoj cai.

Nws yog qhov zoo dua los nkag siab Vim li cas koj tab tom ua qee yam, tsis yog ua qhov muag tsis pom raws li cov lus qhia.

Txog qhov ua tiav, muaj ntau ntau cov lus qhia los ntawm Luthiers uas paub lawv tab tom ua dab tsi hauv lub vev xaib, yog li kuv pom zoo tham nrog lawv ua ntej dhia mus rau qhov ua tiav.

Kuv, ntawm chav kawm, tsis tau ua li ntawd, yog li kuv tau siv lub foob tsis raug, ua rau muaj cov nplais me me. Tsis txhob ua li ntawd.

Ua koj cov ntawv hauv tsev.

Kauj Ruam 15: Txheeb thiab Txuas Tus Choj

Cov kauj ruam no yooj yim heev, tab sis rov ua dua, npaj tawm koj txoj kev clamping thiab sim ua ntej ua ntej gluing. Kuv siv tus ntoo txheem txheem los txuas tus choj.

Kauj Ruam 16: Nruab Hluav Taws Xob thiab Kuaj

Tam sim no yog lub sijhawm los ua kom koj cov hlua zoo nkauj. Ntxiv rau koj tsis xav kom nws flopping ib puag ncig hauv lub cev thiab ua suab nrov nrov lossis tsis zoo tseem tab tom tawg ntawm theem.

Tus lej Arduino tuaj yeem hloov kho tshiab los ntawm USB chaw nres nkoj, yog li tsis tas yuav tsum cais nws tshwj tsis yog koj xav tinker.

Kauj Ruam 17: Txhim Kho Tuners thiab Txoj Cai Ntsuas

Koj kuj tseem yuav xav tau qib cov nyom thiab ua si nrog teeb tsa me ntsis, tab sis vim li cas thiaj txhawj xeeb tam sim no, thaum koj nyob ze rau qhov kawg?

Kuv hloov kho cov tuners thiab siv cov hlua Aquila zoo, uas tsis pab lub suab zoo li cas. Yog li nco ntsoov tias thaum koj tab tom tua nyiaj rau hauv txoj haujlwm ukulele …

Kauj Ruam 18: Ua Haujlwm Uke

Qhov kawg Arduino code nyob ntawm Github. Muaj qee txoj kab hauv txoj cai los txhawb kev txhim kho yav tom ntej (zoo li kev ua haujlwm metronome thiab "sliders" rau cov zaub (UI ntsiab lus uas zoo li slider)

Txoj cai no siv Lub Tsev Qiv Qub Encoder (Rotary Encoder Arduino Library) los tswj cov neeg siv khoom los ntawm Rotary Encoder.

Nws kuj tseem siv Adafruit Neopixel lub tsev qiv ntawv thiab tus lej piv txwv nyob ntawm no. Lub tsev ua yeeb yam thiab zaj sawv zaj sawv tau los ntawm cov piv txwv muab nrog lub tsev qiv ntawv. (saib strandtest.ino).

Cov tsav tsheb tso tawm yog muab los ntawm 4D cov kab ke thiab pom ntawm Github ntawm no.

Muaj ob txoj haujlwm tshwj xeeb uas tau siv rau txoj haujlwm Ukulele. Thawj qhov ua raws lub tsev qiv ntawv chord, thiab qhov thib ob nthuav tawm cov kab ntawv kab lus uas siv cov cim kev cai.

Daim duab txuas nrog qhia pom cov chaw fretboard LED thiab lawv sib txuas li cas. LED 0 yog nyob rau sab xis sab xis.

Kauj Ruam 19: Yuav Qhia Li Cas Chord

Kev ua haujlwm DisplayChord qhia txog cov haujlwm ntiv tes (thawj txoj haujlwm tsuas yog tam sim no) rau txhua chord. Chords xaiv los ntawm tus neeg siv (hauv paus ntawv thiab qhov zoo) tau khaws cia ua khub ntawm qhov ntsuas. Cov no yog siv los saib cov ntiv tes rau txhua tus chord.

Kuv siv "GCEA" cov cim sau cia chords (piv txwv li "A" yog "2100"). Cov chords tau npaj ua ntej suav rau txhua daim ntawv hauv paus thiab khaws cia hauv qhov sib txawv sib xws rau qhov zoo ntawm chord. (yog li, Qhov loj, tau khaws cia hauv thawj qhov chaw ntawm kab ntawv "majorChords", sib xws rau "2100").

char* majorChords = {"2100 / n", "3211 / n", "4322 / n", "0003 / n", "1114 / n", "2220 / n", "3331 / n", " 4442 / n "," 2010 / n "," 3121 / n "," 0232 / n "," 5343 / n "};

Nco tseg tias txij li qhov no yog kab ntawv kab ntawv txhua tus lej kuj tseem tuaj yeem sawv cev tus lej hex rau tus lej rau qhov haujlwm tsis txaus siab ntau dua 9. Ntawd yog, A thiab B yuav sawv cev LEDs 10 thiab 11. Rau thawj txoj haujlwm chords, qhov no tsis yog qhov teeb meem).

Cov hlua LED tau xaim ntev hauv kab ntawm 12 (ib qho octave) raws txhua txoj hlua (pib nrog A txoj hlua), tom qab khiav ntawm 12 pib ntawm thawj qhov kev ntxhov siab ntawm txoj hlua tom ntej (saib daim duab hauv kauj ruam 18). Qhov no yog qhov tseem ceeb rau lub txheej txheem los txiav txim seb lub teeb twg qhib rau lub chord muab. Qhov ntawd txhais tau tias pixels 0 txog 11 yog A hlua LEDs, 12 txog 23 yog E hlua LEDs, thiab ntxiv rau. Thaum txheeb xyuas A = "2100" (khaws ua ib txoj hlua, kuj tseem muaj qhov tsis muaj qhov xaus "\ n" hauv txoj cai), peb txhais nws li: tsis muaj pixels ntawm A txoj hlua raug teeb, lossis ntawm txoj hlua E, pixel 0 (fret 1) ntawm txoj hlua C tau teeb thiab pixel 1 (fret 2) ntawm G txoj hlua. Nco ntsoov tias "0" raug kaw, tsis yog thawj LED. Raws li txoj kab hluav taws xob, peb xav ua kom pom lub teeb ci LED 24 thiab 37. Cov cai los tso saib lub chord tau qhia hauv qab no.

rau (int i = 0; i <4; i ++) {if (int (chord - '0')) {// algorithm los cais cov hlua chord int ledNumber = int (chord - '0') + (3 - kuv) * 12 - 1; // saib cov lus sib tham saum toj no, (3-i) yog thim rov qab qhov Performance index.setPixelColor (ledNumber, 0, 125, 125); // setPixelColor (coj tus lej, tus nqi liab, tus nqi ntsuab, tus nqi xiav)}}

Yog tias daim ntawv txheeb xyuas yog tias coj tawm. Yog tias nws tsis yog nws yuav siv tus nqi ascii ntawm tus ua cim, chord , thiab rho tawm tus ascii tus nqi rau '0' kom tau coj tus lej kom pom kev.

strip yog ib qho piv txwv ntawm chav kawm Adafruit_NeoPixel. SetPixelColor muaj nuj nqi teev cov xim rau xam pixel (tsau ntawm (0, 125, 125) hauv qhov no.

Kauj Ruam 20: Yuav Ua Li Cas Tso Tawm Cov Lus Scrolling

Yog li peb muaj 12 x 4 kab ntawm LEDs … vim li cas ho tsis ua rau nws pom lwm yam uas tsis zoo nkauj zoo li lub teeb pom kev zoo!

Thawj qhov teeb meem yog qhov pom qhov siab (4) yog qhov txwv vim muaj cov hlua ntawm Uke. Kab rov tav kab rov tav yuav feem ntau tsis raug cai, tab sis nyob rau hauv txoj kab ntsug, peb tuaj yeem txhawb 4 x 5 cim ua haujlwm ntsug.

Npaj cov cim ua tsib kab "ntsug" txhais tau tias ob lub cim tuaj yeem tso tawm ua ke tso cai rau ib kab kab ntawm txhua tus cim.

Qhov nyuaj yog tias tsis muaj txheej txheem 4 x 5 tus cim teeb tsa. Kuv ua kuv tus kheej siv daim ntawv nthuav qhia txuas nrog. Kuv tau muab txhua kab rau ib tus lej hex tus nqi (4 cov khoom sawv cev uas pixel nyob lossis tawm). Qhov ua ke ntawm tsib qhov hex qhov tseem ceeb yog tus yam ntxwv (piv txwv li "0" yog 0x69996).

Cov txiaj ntsig rau txhua tus cim tau khaws cia hauv ib qho array hauv kev txiav txim ASCII. Cov ua cim tau ua qee qhov kev pom zoo nrog qee cov ntawv, tab sis feem ntau yog qhov tseeb tsim nyog. (cov ntawv sau hauv qab ntawm daim ntawv nthuav qhia yog cov tswv yim kuv tau ua si nrog vim peb muaj xim raws li qhov kev xaiv, peb tuaj yeem ntxiv "qhov tob" rau tus ua cim thiab muaj peev xwm tau txais qee qhov kev daws teeb meem ntxiv.

Cov hlua los tso tawm muaj nyob hauv cov hlua sib txawv, cov lus.

Tsis tau tsim los sawv cev rau tus ua cim. Kuv kwv yees kuv tuaj yeem tsim qhov tsis loj nrog tag nrho cov lus txhais ua ntu zus, tshwj xeeb tshaj yog txij li cov lus feem ntau yuav tsawg dua 20 tus cim lossis li ntawd. Txawm li cas los xij, Kuv tau xaiv hloov los tsim kho peb tus cim (18 bytes) tsis. Tsuas yog ob qho ntawm cov cim tau nquag pom, thiab qhov thib peb yog saib ua ntej, qhov twg yog tus cim tom ntej raug thauj khoom. Cov hlua LED (xav txog nws yog qhov hloov pauv loj rau npe) tau ntim nrog 48 khoom rau txoj hlua. Kuv nkim qee qhov chaw nco kom ua qhov yooj yim dua rau lub tswv yim. Txhua tus nibble tau txais nws tus kheej qhov chaw nco, ob npaug rau qhov xav tau, tab sis nws tsis ntau npaum li cas muab qhov tsis zoo.

Qhov tsis raug thauj khoom nrog tus cim tom ntej thaum qhov ntsuas qhov tso tawm (tus pointer) tau txais mus rau tus cim ciam teb (outputPointer ntawm 5, 11, lossis 17).

Txhawm rau thauj tus tsis, peb rub thawj tus cim hauv "xov" raws li tus lej ASCII thiab rho tawm 48 kom tau txais qhov ntsuas nyob hauv asciiFont array. Tus nqi ntawm qhov ntsuas tau khaws cia hauv codedChar.

Thawj feem ntawm cov lus tau hloov pauv sib xws rau LEDs 47, 35, 23, thiab 11 (hauv qab ntawm cov zaub). Yog li rau tus lej xoom 0x0F999F, F (sab laug ib qho) tau hloov ua ntej, 9 thib ob thiab ntxiv rau.

Tus cwj pwm tom ntej yog thauj los ntawm qhov ncauj txhua nibble thiab hloov nws mus rau sab xis. Rau qhov piv txwv saum toj no, cov txheej txheem muab (0x0F999F & 0xF00000) >> 20, tom qab ntawd (0x0F999F & 0x0F0000) >> 16, thiab lwm yam.

koj index; yog (outputPointer == 17 || outputPointer == 5 || outputPointer == 11) {char displayChar = message.charAt (messagePointer); // tuav thawj tus cim ntawm cov lus ntev codedChar = asciiFont [displayChar - 48]; yog (displayChar == 32) codedChar = 0x000000; messageBuffer [bytePointer+5] = byte ((codedChar & 0xF00000) >> 20); // npog tag nrho tab sis qhov kawg nibble thiab hloov nws dhau 20 (thiab ntxiv rau) messageBuffer [bytePointer+4] = byte ((codedChar & 0x0F0000) >> 16); // qhov no yuav tsum tso ib qho nibble rau qhov chaw cim xeeb messageBuffer [bytePointer+3] = byte ((codedChar & 0x00F000) >> 12); // tag nrho rau tus sawv cev ntawm tus cim messageBuffer [bytePointer+2] = byte ((codedChar & 0x000F00) >> 8); messageBuffer [bytePointer+1] = byte ((codedChar & 0x0000F0) >> 4); messageBuffer [bytePointer] = byte ((codedChar & 0x00000F)); yog (bytePointer == 0) {// tswj lub voj ncig ntawm lub bytePointer bytePointer = 12; } lwm {bytePointer -= 6; // peb tau sau los ntawm hauv qab; NCO TSEG: yuav tsum saib qhov thim rov qab kom pom tias nws ua kom yooj yim dua} yog (messagePointer == message.length ()-1) {// tuav lub voj nyob ib ncig ntawm cov lus messagePointer = 0; } lwm {messagePointer += 1; // txav mus rau tus cim tom ntej}}

Thaum tsis tau thauj khoom, nws dhau los ua teeb meem ntawm kev mus saib qhov twg tus pointer tso tawm nyob ntawm thiab thauj cov hlua LED nrog qhov raug 48 khoom (tam sim no 4 thiab yav dhau los 44). Raws li tau hais ua ntej, kab txaij yog qhov piv txwv ntawm chav kawm NeoPixel thiab teebPixelColor teeb xim (RGB) ntawm txhua lub pixel. Cov yeeb yam () muaj nuj nqi hloov tawm cov txiaj ntsig pom rau LED hlua.

// voj mus txuas ntxiv hloov qhov tsis

// xav sau tag nrho cov kab txaij ntawm txhua qhov dhau los ntawm lub voj, tsuas yog pib qhov chaw hloov pauv rau (int row = 12; row> 0; row--) {index = outputPointer + (12-row); yog (index> 17) index = outputPointer+(12-kab) -18; // loop yog ntau dua 17 rau (int column = 4; column> 0; column--) {strip.setPixelColor (uint16_t (12*(column-1)+(row-1)), uint8_t (RedLED*(bitRead) (messageBuffer [index], column-1))), uint8_t (GreenLED*(bitRead (messageBuffer [index], column-1))), uint8_t (BlueLED*(bitRead (messageBuffer [index], column-1)))); // ntawm txhua qhov chaw teeb lub LED yog tias qhov me me yog ib qho}} // outputPointer cov ntsiab lus mus rau qhov qis tshaj tam sim no byte hauv cov hlua pom yog (outputPointer == 0) outputPointer = 17; lwm tus outputPointer -= 1; strip.show (); }

Kauj ruam 21: Ua rau lub ntiaj teb xav tsis thoob nrog Koj Cov Ukulele Zoo Tshaj

Qhov kawg Ukulele tus qauv coj mus txog 6 lub hlis pib thiab nres kom rub tawm.

Ntau yam thev naus laus zis tshiab los kawm thiab tej zaum qee qhov kev ua haujlwm ntoo thiab suab paj nruag txoj kev xav rau khau raj!
