Korona LED manja: nthano kapena chenicheni?

garlands choyambirira - njira azikongoletsa zipinda amene momasuka ndi chikondwerero maganizo. anthu ochepa mukudziwa kuti korona LED, ndi manja ake anapanga - ndi mosavuta chopindulitsa. Mudzatha kulenga njira zimene zigwirizane inu ndi kupsa mwangwiro mu m'mudzimo.

ndi nkhata zamaluwa Kodi

Pa maalumali mungapeze zambiri zimene mungachite osiyana, poopa kuti kusochera mu zosiyanasiyana zonse muyenera kudziwa mmene ntchito nanga kusiyana kwake. Podziwa kuti wotereyo chiwembu cha garlands LED, angakuthandizeni ngati musankha kuchita nokha.

Mitundu ya zingwe:

1. Traditional korona ulusi.
2. thumba korona.
3. Makatani.
4. Mmodzi wa mitundu ya nsalu yotchinga - garlands, icicles.
5. Dyurolayt.
6. Kiplayt.
7. Stroblayt adzalenga kukulowa.

Tsopano kuti wasankha pa mitundu ya garlands, ayenera analengedwa ndi inu bwinobwino mawaya mitundu ya zakudya zomwe zingagwiritsidwe ntchito kulenga garlands ndi manja awo.

Mitundu ya zingwe ndi magetsi

garlands Modern anapanga pogwiritsa ntchito mitundu itatu ya waya. Kuti mphira ichi, silikoni ndi PVC zipangizo akhoza ntchito. Pakuti zokongoletsa panja ntchito woyamba mitundu iwiri ya mawaya, ngati ali mkulu litulukira zosagwira ndi mokwanira kugonjetsedwa ndi kusintha kutentha. Mu malo, mukhoza kugwiritsa ntchito bajeti LED Khirisimasi korona ndi PVC waya.

Malinga ndi mtundu wa chakudya munthu amatha kusiyanitsa mitundu iwiri: yoyenda yokha ndi magetsi. Woyamba ndi abwino kwa ulemerero wa pamakoma ndi malo sikutheka kuti abweretse magetsi. garlands izi LED msewu kuthamanga pa mabatire. Chifukwa mowa mphamvu otsika akhoza ntchito nthawi yambiri. A kuphatikiza lalikulu kuyenda mosavuta utenge pa pantchito. Magetsi pulagi mu zitsulo ndi.

Yankho 1: Pangani korona wa kiyibodi akale

Kodi chimachitika ndi kuti korona n'zofunika yaifupi zotheka nthawi, ndi ndalama kuti agule izo apo. Ndiye kuthandiza msonkhano "korona anatsogozedwa, zopangidwa ndi manja ake." Taganizirani kwambiri bajeti njira rework zida akale kompyuta ofesi, monga keyboards ndi mbewa.

Agwire ntchito chofunika:

• Zingapo zosafunika kiyibodi (simungathe ntchito).
• Soldering chitsulo.
• Resistors.
• Magetsi tepi.
• Chubu-mapeto manja Chosafooka.
• Kapena rosin kamwazi.

Choyamba tiyenera kuchotsa kiyibodi ku mawaya zosiyanasiyana zosafunika ndi modekha kusagwirizana USB-chingwe. Kuti festoon anatsogozedwa, zopangidwa ndi manja ake anali mkulu kalasi, ayenera kuyang'ana kwa osachepera keypads asanu. Funsani mozungulira ndi abwenzi, abwenzi, kapena kupita ku maonekedwe m'deralo. Aliyense ali osachepera atatu mababu LED kuti atumikire monga zizindikiro mabatani lamulo. Ngati katundu ndi zosafunika Bakuman, mitengo izo sizidzatero, chifukwa pali anasonkhana ambiri LEDs. Njira chidwi kwambiri ndi analandira mwa kusakaniza mababu osiyana kuwala kwa zipangizo zosiyanasiyana ofesi.

malangizo

Dismantle ndi kuchotsa kiyibodi kumeneko ndalama zochepa kwa Mtsogoleri wa. Kuti adzapitiriza soldered kumtunda babu. Nkofunika kudziwa kuti korona aliyense LED (anapanga ndi manja awo) ndi mbali 12, amene olumikizidwa ku kufanana kwa resistors lapansi. Ngati timaona kuti ndi USB wamba imapereka voteji 5 volts, ndi mphamvu panopa 500 MA.

Mavuto achilengedwe aliyense mchitidwe si upambana 5 volts. Ngati inu kugwirizana nawo mwachindunji, iwo overheat ndi kutentha msanga. M'pofunika kuchepetsa mavuto. Izi zikhoza kutheka ndi zinthu pairwise soldering. Motero, aliyense wa iwo kuchepetsa ena. Koma njirayi si mulingo woyenera. Ndi bwino ntchito zina voteji chimango izo sizikanakhala kungapondereze pa chipwirikiti cha magetsi Mipikisano wachikuda.

Tenga chingwe ndi kuwotcha kuluka pang'ono mbali imodzi. Mu anabala mazenera solder. Kotero inu adzalenga ndi manja awo LED festoon kutalika chofunika. Kukwaniritsa kufunika mawonekedwe, kutalika ndi mumakhala malo poyera. Mkati chingwe pachimake kudya opanda - Black, kuphatikiza - wofiira. Lumikizani dongosolo lonse ndi kuyamba kuyesa LED garlands msewu.

Yankho 2: Pangani korona kuchokera zikande

Ngati mukufuna kupanga korona chidwi kuti adzakomana amafuna mwachindunji, ndiye chonde werenganibe chithunzi pansipa. Galimoto garlands LED kulola kuzindikira ndondomeko ndi kumvetsa mwatsatanetsatane ndondomeko ya zinthu zonse.

Zikatero, ngati ife kuganiza kuti mwadzidzidzi lamulo pafupipafupi wa multivibrator chifukwa cha kukameta ubweya pa malekezero a transistors zonse zilipo, izo anapempha funso zovuta za M'MALO kumunda ndi transistors ochititsa kuti. Pankhaniyi m'pofunika kuganizira pafupipafupi kusinthitsa, ngati nthawi kuchepa, ndi LEDs pa korona, adzakhala kusinthana mofulumira kwambiri.

Choncho ntchito VT-1 ndi VT-2 zikhoza kukhala zofanana ndi KTZ101 KTZ15. Kudziwa voteji ndi dontho ake kudutsa chingwe LED, mungathe kugwiritsa ntchito R2 transistor.
