Zoo li txhua yam kuv tsim, Kuv ib txwm xav txog txoj hauv kev kom siv ntau yam ntau li kuv ua tau. Kuv txaus siab rau kev tshawb fawb zoo ntawm Amazon, thiab zoo siab txhua lub sijhawm pob khoom tshiab tuaj txog … tab sis siv cov khoom uas kuv muaj ntawm tes yog qhov kev xav zoo.

Nov yog ib qho ntawm cov tsim, yog li kuv tau txiav txim siab siv qhov yooj yim tam sim no LED tsav tsheb Circuit Court uas kuv nyuam qhuav kawm paub txog online.

Lub hauv paus tseem ceeb uas txiav txim siab tam sim no xa mus rau lub teeb LED yog lub tshuab tso tawm suab. Txhawm rau piav qhia qhov yooj yim ntawm no, Kuv yuav hais qhia tias qhov hluav taws xob poob thoob plaws qhov emitter resistor yog qhov tsis tu ncua ntawm 0.5 vdc ua tsaug rau diodes 1 thiab 2 txuas nrog lub hauv paus raws li qhov faib hluav taws xob.

Hauv Version 1 thiab Version 2, Kuv tau sim nrog 15 mA txog 30 mA LED tsav tam sim no rau txoj hlua LED.

Kev suav lej rau emitter resistor resistor xav tau:

0.5 volts / 0.015 amps = 33 ohms

los yog

0.5 volts / 0.030 amps = 16 ohms

Hauv Version 2 qhov sib txawv tseem ceeb yog 270 ohm resistor ntxiv los ua kom tag nrho cov hluav taws xob tam sim no kos rau tsuas yog ntau dua 50 mA kom khaws qee lub txhab nyiaj roj teeb los ntawm kev kaw tom qab li 30 vib nas this.

Hauv Version 3… Kuv yuav tos txog thaum tom qab los tham txog qhov kev hloov kho no.

Version 1 Kev Xeem:

Kuv siv Hype HW-440-ASST lub txhab nyiaj uas ua haujlwm tas li (tsis kaw) thaum ua lub zog ntawm 20 LEDs.

Nco tseg: Lub sijhawm suav suav (them tag nrho) yuav yog 4, 400 mAh / 30 mA = 145 teev

Kuv ces sim Version 1 nrog ONN ONA18W102C lub txhab nyiaj fais fab, uas yuav pib kaw tom qab 30 vib nas this.

Version 2 Tsim thiab Xeem:

Tom qab ntawd kuv muab tso ua ke ib yam ntawm Circuit 1 ntawm lub khob cij, thiab ntxiv qhov ntxiv 270 ohm resistor rau USB + thiab USB - ntsia. Qhov no tau nce tag nrho cov hluav taws xob tam sim no kos rau 50 mA. ONN ONA18W102C yuav yog lub zog siv tas li. Qhov no dhau los ua Version 2 uas yuav ua haujlwm rau ntau lub txhab nyiaj USB.

Lub sijhawm suav suav (them tag nrho) rau ONN ONA18W102C lub txhab nyiaj yuav yog 3, 350 mAh / 50 mA = 69 teev. Qhov no yuav ua kom pom kev ci ntsa iab tag nrho lub sijhawm no.

Thawj qhov ntsuas roj teeb thiab xav:

Cov roj teeb CR2032 tau ntsuas ntawm 3 vdc nrog lub peev xwm ntawm 240 mAh, thiab qhov chaw khav theeb tias lawv yuav nyob ntev 72 teev nrog kev siv tas li. Kev tiv thaiv sab hauv ntawm CR2032 roj teeb txwv tam sim no rau Fairy Lights, thiab yog vim li cas thiaj tsis muaj qhov txwv kev tiv thaiv hauv qhov tsim thawj. Txawm li cas los xij, txhua qhov chaw uas kuv saib qhia tias CR2032 tsis nyiam tso tawm ntawm qhov siab (30 lossis li mA).

Kuv tsis tuaj yeem lees paub tseeb ntawm qhov no, tab sis kuv rov qab pom lub teeb pom kev zoo dua qub tom qab 3 yav tsaus ntuj (ntawm 4 teev sijhawm). Tsis muaj txoj hauv kev uas koj tau txais "khawv koob" tawm ntawm cov roj teeb no. Kuv tau lees paub los ntawm kev sim tias lub teeb zoo li npau taws heev thaum lub roj teeb tsoo 2.5 vdc ib lub xov tooj.

Kuv yuav tau ua qee qhov kev sim lub neej tiag tiag thiab hloov kho cov ntawv no tom qab hnub tom qab, tab sis kuv xav tias 3, 350 mAh @ 5 vdc lub tsev txhab nyiaj yuav tsum ua tiav zoo dua 240 mAh @ 6 vdc (2 lub roj teeb hauv koob) CR2032.

Dhau li, lub hom phiaj ntawm no yog lub sijhawm ua haujlwm ntev dua, thiab thaum kawg tsawg dua CR2032 cov roj teeb tau "siv" thiab rov ua dua tshiab.

Mus Farther:

Koj twv nws… Version 3 yog xeeb, yog li nyeem ntxiv!

Version 3 siv tam sim no ntxiv uas tau hloov pauv (pov tseg) rau hauv 270 ohm resistor hauv Version 2.

Txij li thaum peb tau tsom mus rau 50 mA raws li tag nrho cov kev kos tam sim no txhawm rau ua kom lub zog fais fab nruab nrab muaj zog, peb tuaj yeem txhim kho. Kuv tau sim qhov twg kuv siv txoj hlua teeb nrog 15 mA, thiab txoj hlua teeb thib ob nrog 30 mA thiab nug kuv tus poj niam yog tias nws tuaj yeem pom qhov txawv. Nws tig rov los thiab tawm mus ntau zaus, thiab qhia tias nws tsis tuaj yeem pom tiag tiag thiab sib txawv.

Qhov kev sim no tau lees paub qhov kev daws teeb meem zoo dua yuav tsum ua kom muaj zog ob (2) Fairy lub teeb hlua ua ke, thiab tsav lawv nrog 50 mA tam sim no. Koj tuaj yeem pom hauv cov txheej txheem txuas rau Version 3, tias txhua yam uas xav tau yog hloov pauv qhov ntsuas hluav taws xob R2 txog 10 ohms, thiab txuas kab thib ob lub teeb ua ke.

Txhawm rau suav lub zog los ntawm R2 nrog Ohm Txoj Cai:

P = E x I

E = 0.5 volts (hla R2)

Kuv = 50 mA (dhau R2)

0.5 x 50 = 0.025 W

Peb tuaj yeem nyab xeeb siv 10 ohm 1/4 watt (250 mW) resistor rau daim ntawv thov no.

Daim duab 2 qhia txog qhov ntsuas ntsuas kos 50 mA raws li kev suav.

Kuv tau ntxiv ob peb cov duab ntawm cov txheej txheem tsim los qhia txoj kab txuas.

Version 3 ua tiav thiab ntsuas ntawm kuv lub rooj ntev zaum.
