Nov yog lub desktop me me USB siv LED Menorah. Muaj ntau ntau lub khoos phis tawj Christmas kho kom zoo nkauj thiab khoom siv, tab sis ob peb yog tias muaj Channakah dai kom zoo nkauj. Nov yog qhov yooj yim tus nqi qis LED teeb tsa los ntawm tus qauv USB chaw nres nkoj.

Kauj ruam 1: Cov ntaub ntawv

Koj yuav xav tau. -9 LEDs (~ $ 2) -soldering iron-solder-USB pigtail cable (~ $ 2) -6 hookup wire-pliersLEDs tuaj yeem sib xyaw xim lossis txhua xim tib yam, koj txiav txim siab. Koj tuaj yeem tau txais LEDs los ntawm yuav luag ib lub khw hluav taws xob zoo li Xov Tooj Cua lossis hauv online. Xim yog qhov nyiam ntawm tus kheej thiab tsis muaj teeb meem tiag tiag. Kuv muaj qee qhov khoom seem tso nyob ib puag ncig, tab sis zaum tom ntej kuv xav tias kuv yuav siv cov Purple LEDs txias no los ntawm Allied Electronics.

Kauj Ruam 2: Tsim Circuit Court

Txuj USB tso tawm yog 5VDC thiab tuaj yeem kos txog li 100mA. Peb tsuas xav tau ~ 2VDC rau txhua LED@30mA. Koj qhov kev nrug deb yuav txawv nyob ntawm LEDs koj xaiv. Hmoov zoo rau peb muaj tus kws pab tswv yim uas peb tuaj yeem txuas tus lej rau hauv uas yuav pab tsim cov phiaj xwm rau peb. Siv tus kws pab tswv yim LED no los pab nrog koj tsim - LED Wizard. Kuv xaiv 2x4 array nrog 1 ntxiv LED. txhua 27 ohm resistor dissipates 24.3 mW tus wizard hais tias xim xim rau 27 yog liab violet blackthe wizard xav tias 1/4W resistors tau zoo rau koj daim ntawv thov 100 ohm resistor dissipates 90 mW tus wizard hais tias xim xim rau 100 yog xim av dub lub ntsej muag 4W resistors yog qhov zoo rau koj daim ntawv thov ua ke, txhua tus resistors dissipate 187.2 mWtogether, diodes dissipate 567 mWtag nrho lub zog faib tawm los ntawm cov array yog 754.2 mWthe array thim tam sim no ntawm 150 mA los ntawm qhov chaw

Tam sim no koj muaj txhua yam koj xav tau, muab tshuaj txhuam nws ua ke. Nco ntsoov tias qhov tsis zoo ntawm LED yog tiaj tus thiab ib txwm muaj cov hmoov txhuas luv dua. Siv lub pliers khoov thiab txiav cov hlau raws li xav tau. Cov coj yuav tsim lub cev Menorah. Kuv siv cov LED ntxiv ua Shamash nyob nruab nrab. Kuv kuj tseem siv cov LED no los ua lub hauv paus rau qhov kab zoo thiab tsis zoo koom nrog. Kuv siv cov hlua txuas txuas los txuas cov kab zoo ua ke kom lawv tsis txhob kov cov hlau tsis zoo, thiab muab tag nrho cov tsis zoo coj ua ke raws li qhia hauv daim duab. Pom qhov sib txawv ntawm daim duab kos duab thiab daim duab tiag (duab tsis zoo, Kuv paub) ntawm qhov tsis zoo ua rau cov laug. Los ntawm kev sib tsoo, Kuv tau siv cov tshuaj tiv thaiv rau sab nraud ua ke tsis hloov pauv. Thaum kuv lub voj voog tseem ua haujlwm, tus khub sab nraud tseem ceeb dua li lwm tus. Nco ntsoov rau tus kheej… nco qab txoj cai ohms lwm zaus.

Kauj ruam 4: Ua tiav

Tam sim no tias koj cov khoom sib dhos tag nrho ua ke, ua tiav los ntawm kev siv lub USB pigtail. Muaj plaub lub xov hlau ntxiv rau daim ntaub thaiv ntawm tus pigtail. Tsuas yog qhov xav tau yog cov xov dub thiab liab. Lwm qhov tuaj yeem raug txiav rov qab rau rwb thaiv tsev thiab tsis quav ntsej. Tua nws tag nrho ua ke thiab ntsaws rau hauv. XAV TAU-Tsuas yog yuav tsum tau txuag thiab paub tseeb tias kuv thiab cov me me ua rau lawv tus kheej poob siab, Kuv tau npog kuv cov kab xev kua uas koj tuaj yeem tau ntawm Wal-Mart lossis khw muag khoom tsheb. Cov hlua hlau txuas txuas yuav tsum txaus kom koj tsis txhob poob siab koj tus kheej thiab nws tsis xav tau tiag tiag. Tsib volts kuj yuav tsis ua mob rau koj yog tias koj ua rau koj tus kheej poob siab, tab sis kuv tus poj niam tsis ntseeg kuv. Tam sim no koj muaj USB Menorah (lossis Chanukiyah yog tias koj xav tau) zaum saum koj lub monitor lossis lub rooj ntawm haujlwm. Kuv lub tswv yim tom ntej yog txhawm rau qhov no mus rau hauv Borax Crystal daws kom cov muaju tuaj yeem loj hlob ntawm nws. Tej zaum lwm xyoo.
