Muaj ntau cov vis dis aus hauv Youtube txog kev kho lub teeb hnub ci vaj; txuas lub roj teeb lub neej ntawm lub hnub ci vaj teeb kom lawv ua haujlwm ntev dua thaum hmo ntuj, thiab ntau yam ntawm lwm qhov hacks.

Cov Lus Qhia no yog qhov txawv me ntsis tshaj qhov koj pom ntawm Youtub. Qhov no yog nyob ntawm kev caij tsheb kauj vab vaj teeb los ntawm ci dawb rau nti RGB lossis strobe LEDs.

Kauj ruam 1: Thawj Circuit Court

Tam sim no qhov no tsis yog hais txog lub vaj teeb hnub ci koj tsuas yog hloov lub teeb ci dawb LED rau lub nti RGB LED thiab lawv ua haujlwm zoo li thawj zaug hauv Circuit Court.

Nrog rau qhov Circuit no koj tsuas tuaj yeem hloov lub teeb ci dawb LED nrog lub nti LED, RGB lossis Strobe thiab kev ua haujlwm hauv Circuit.

Kauj Ruam 2: Cov Cuab Yeej & Cov Khoom Siv

Diodes 1N4148 lossis 1N5817

LEDs Chip RGB lossis Strobe

Capacitors 0.1 uf rau 10 uf

Screwdriver qhib lub hnub ci teeb

Sab Cutters

Lub caij nplooj ntoo hlav

Koob Ntshav Ntshav

Solder

Soldering Hlau

Kauj Ruam 3: Yooj Yim Tsim Circuit Court

Yog tias koj xav tsim koj tus kheej Circuit, qhov no yog qhov yooj yim tshaj plaws thiab yooj yim Circuit Court los tsim.

4 volt hnub ci cell

Chip RGB LED

1N5817 diode

5.6 kΩ resistor

100 Ω resistor

S8550 lossis ib lub hom phiaj dav dav PNP transistor

3 x 1.2 volt roj teeb

Ib co xaim

Yuav ua li cas Circuit Court ua haujlwm no yooj yim; thaum lub hnub nce qhov nqi zoo tau thov rau lub hauv paus ntawm transistor qhib PNP transistor. Qhov no tig tawm RGB LED tso cai rau txhua qhov tam sim no dhau los ntawm 1N5817 diode kom them lub roj teeb.

Thaum lub hnub poob qis; lub hnub ci ntawm tes tso cai rau tam sim no ntws mus rau lwm txoj hauv kev thov tus nqi tsis zoo rau PNP transistors puag. Qhov no kaw PNP transistor thiab tso cai tam sim no los ntawm cov roj teeb kom ntws los ntawm RGB LED. 1N5817 diode tiv thaiv cov roj teeb los ntawm kev siv tus nqi zoo rau lub hauv paus ntawm PNP transistor.

Kauj Ruam 4: Nce Cycling Lub Hnub Ci Teeb Nrog Joule Thief

Tus tub sab 5252F joule yog cov cuab yeej siv yooj yim; nws hloov 1.2 volts los ntawm cov roj teeb uas tau them rov qab, mus rau qhov muaj peev xwm muaj peev xwm ua kom muaj zog ntawm LED. Siv cov khoom ntawm tus inductor, joule tub sab tig qhov tam sim no rau thiab tawm ua rau qhov ntsuas hluav taws xob tsawg dua thiab txo qhov tam sim no. Koj tuaj yeem pom qhov hloov pauv tam sim no ntawm oscilloscope.

Kauj Ruam 5: Hloov LED

Yog tias koj tsuas yog hloov LED nws yuav tsis pom kev. Qhov laj thawj rau qhov no yog nti LED siv 10 ntau milliamps tam sim no dua li cov dawb LED.

Saib ntawm 5252F cov ntaub ntawv koj tuaj yeem pom tias 270 uH cov khoom siv hluav taws xob 14.5 milliamps thiab nti LED xav tau ntau dua 20 milliamps. Los ntawm 5252F cov ntawv xov xwm koj pom koj yuav tsum hloov pauv inductor rau 150 uH inductor.

Tam sim no lub nti LED teeb tab sis nws tsis hloov los ntawm ntsuab ntsuab xiav. Thaum koj txuas lub oscilloscope mus rau LED koj tuaj yeem pom dab tsi tsis nyob hauv cov ntaub ntawv. Lub nti LED xav tau DC tam sim no. Cov nti hauv LED pib suav kom hloov xim txhua lub sijhawm los ntawm lub zog, yog li txhua lub teeb liab los ntawm joule tub sab yog pib suav thiab nws yeej tsis tau txais rau xim tom ntej.

Txhawm rau kho qhov no koj yuav tsum tau ntxiv qhov tsis rau LED.

Kauj Ruam 6: Tsis Siv Neeg Circuit Court

Lub Circuit Court tsis yog tsuas yog s diode thiab lub capacitor ntxiv rau hauv Circuit Court ntawm joule tub sab thiab nti LED.

Lub diode khaws lub capacitor them thaum joule tub sab teeb liab mus rau 0 volts, tam sim no thaum koj txuas lub oscilloscope mus rau chip LED tsuas muaj me ntsis ripple hauv DC tam sim no thiab nti LED mus los ntawm cov xim sib txawv.

Kauj Ruam 7: Sib sau ua ke thiab teeb tsa

Tam sim no koj muaj RGB lossis Strobe vaj teeb ua haujlwm sib sau ua ke thiab tso lawv sab nraum hauv qhov chaw uas lawv tuaj yeem tau txais lub hnub puv.
