Yuav ua li cas ua kom lub teeb pom kev zoo los ntawm ib tsob ntoo thiab ntau lub LEDs. Qhov no ua ke ua ke ob yam khoom siv ntuj tsim thiab cov khoom siv hluavtaws ntau heev. Kuv nyiam tooj liab ntawm ntoo, Kuv tsis nyiam PCBs. Cov vis dis aus qhia tias koj tuaj yeem ua dab tsi los ntawm kev sib tw "Dial-a-LED" maub los, txwv tsis pub muaj 10 qhov kev teeb tsa ruaj khov, thiab 2 txoj haujlwm tsis ua haujlwm.

Kauj Ruam 1: Cov Khoom & Cov Cuab Yeej

Ib daig ntoo (Hawthorn) los ntawm cov ntoo. Qhov pob zeb hauv zos Ib qho tooj liab tooj liab / khoom plig rau neeg ncig tebchaws Tsis zoo li tus xov tooj Nyij Pooj A USB cable (rau lub koob yees duab, los ntawm ua ntej daim npav-nyeem tau ib txwm muaj) Liab micro LEDs 10x los ntawm cov kab laug sab-tuav ntawm lub qub stereoYellow 5mm LEDs 8X los ntawm cov ntoo Christmas-ntoo qubGreen 5mm LEDs 8X los ntawm cov ntoo Christmas-ntoo qubViolet / UV LED (yuav) Khoom-tseem ceeb tswb-hlauSolid-core mains cable (30A) Qee lub capacitors los ntawm lub qub stereoA xyaum A soldering-ironScrewdriverScissors / riam 2- ib sab epoxy kua nplaum Lub cev muab tub lim (styrene / polyester cob)

Kauj ruam 2: LED los ua ke

Tsuas yog laum qhov hauv ntoo kom haum rau LED "ob txhais ceg". Hauv cov ntu no kuv tau laum qhov rau 10 qhov me me liab LEDs, ib lub qhov rau txhua tus pin. Kev sib txhuam txaus kom ruaj ntseg cov no, txawm hais tias tau ntxiv cov kua nplaum. Wire LEDs hauv kab ua ke nrog tswb-xaim (saib schematic) Cov coj mus rau sab laug yog rau +muab khoom, ua rau sab xis rau hauv av (- ve). Ntawm qhov GND coj yuav txuas rau lub npav loj tooj liab-bar, cov +ve xov hlau yuav raug coj mus rau hauv paus thiab nyab xeeb.

Kauj Ruam 3: Lub Rooj Sib Tham Fais Fab

Sawb cov rwb thaiv tsev los ntawm cov kab hluav taws xob hnyav kom tso cov tub ntxhais tooj liab. Kev kho kom zoo nkauj Lub qhov ntoo hauv cov ntoo kom haum. Qhov tooj liab "khoom" tau tawg nrog rab phom kub kom yaj cov laug uas tuav nws ua ke thiab ib ntawm ob peb daim tau siv koom nrog tsheb npav-bar ua ke ntawm cov ntsiab lus sib txuas Cov duab qhia pom hauv av (-ve) cov hlau, lub +ve lub tsheb npav fais fab tau tsim los ntawm tswb-hlau. Qhov tooj liab yog txhua qhov kev sib txhuam, tsis muaj kua nplaum xav tau.

Kauj ruam 4: Mus txuas ntxiv

Laum ntau qhov, ntxiv ntau LED. Txuas cov LEDs rau hauv av (-ve) npav npav, thiab khiav qhov khoom zoo cia rau hauv ntoo nrog lub tswb-xov. "ntxig rau hauv qhov drilled-qhov. Cov tooj liab tau txiav los ntawm cov xov hluav taws xob mus rau ~¹/₄", thiab kev sib txhuam-haum qhov no zoo heev lom zem, thaum koj tsim tus tsim nyob ib ncig ntawm cov khoom siv. Qhov twg koj cov xov hlau mus yog qee yam ntawm kev txhim kho ntuj. Feem ntau cov LEDs tau ruaj ntseg los ntawm kev sib txhuam, lossis txuas rau cov hlau, tab sis ob peb tau ruaj ntseg nrog kua nplaum. Qhov twg +cov khoom siv tau khiav hauv qab GND lub npav, me me ntawm cov kua nplaum tau ntxiv raws li kev tiv thaiv kev tiv thaiv.

Kauj ruam 5: Lub hauv paus

Ib qho me me-ntsia hlau mus rau ib qho me me ntawm hardboard, tom qab ntawd ruaj ntseg nrog cov muab tub lim. Qee lub pob zeb tau ntxiv, nias rau hauv cov muab tub lim thaum nplaum, kom hnyav thiab zoo nkauj. Qhov screws tau raug tshem tawm thaum cov muab tub lim tau khov lawm. qhov hnyav kom khaws qhov ncaj.

Kauj Ruam 6: "Dial-a-LED" Controller

Cov xov tooj khib kuv pom ntawm kev ua lag luam yog nyob ib puag ncig ntawm ob-ncej 12-txoj haujlwm hloov pauv. Kuv tshem tawm qhov hloov pauv thiab txuas cov LEDs raws li tau qhia hauv cov qauv Tam sim no. Cov txiaj ntsig tau muab txuas rau lub tshuab txuas hluav taws xob los ntawm cov yeeb yaj kiab qub, tso cai rau tsob ntoo kom tsis txhob ntsaws yooj yim Ib qho qub USB cable tau hle, qhov av txuas nrog hauv av (-ve) tooj liab npav, thiab (liab) +5V xaim pub rau qhov hloov pauv ntawm qhov hloov thib ob (tsuas yog vim nws nyob ntawd)

Kauj ruam 7: Schematic

Lub violet LED tau khiav ntawm kwv yees li 10mA nws zoo. Kuv tau siv daim ntawv ntsuab tsim nrog cov cim kos-tus cwj mem ntawm ntoo, tab sis nws tsis tuaj yeem thaij nws (tsis nrog kuv lub koob yees duab li cas los xij) Cov micro LEDs ua haujlwm tau zoo ib yam nkaus. Cov ntsuab thiab daj daj tau xub txwv nrog 39 Ohm resistors, tab sis muaj zog me ntsis yog li cov no raug tshem tawm. Qhov no yog vim li cas thiaj muaj 0 Ohm resistors hauv cov txheej txheem. Kuv tau sawv cev rau ob ntu ntawm kev hloov pauv ib sab, lawv nyob saum ib leeg, thiab txhua tus muaj caj npab tig txuas cov chaw nruab nrab mus rau sab nraud.
