Indlela yokwenza laser ngezandla zakho ngaphandle nezindleko

Laser - into ewusizo futhi ezithakazelisayo. Zonke cishe idlalwe njengoba ingane nge ezishibhile izikhombo Chinese. Nokho, ngokuhamba kwesikhathi kuba sobala ukuthi leli kuwubala. Bese iqala uvuthwe umbono zendlela yokwenza esingathí sina, laser enamandla oluzonquma steel, njengase-movie. Steel, maye, kunzima kakhulu ukusika, it can amathuluzi zezimboni onamandla kuphela. Ngakho masizame ukuqala ukufunda indlela ukwenza laser ngezandla zakhe, ukuze ukusika okuthile okuncane eqinile, ezifana plastic.

amasu

Uma nicela noma yini unjiniyela mayelana nendlela ukwenza laser ngezandla zakhe, weluleka ukuthatha isibani enamandla futhi ugxile ukukhanya ku ugodo. Nokho, lokhu akukhona ngempela laser. Umehluko omkhulu phakathi ukukhanya laser kusukela yokuvumelana flashlight uvumelanise. I laser kwakuwukuhlasela kwangempela lokhu, kubalulekile ukuthatha, isibonelo, igama elifanayo zedivayisi umbhali (edingekayo!) CD noma i-DVD-drive. Laser kukhona wawunamandla ngokwanele, ayanda isivinini ukurekhoda, namandla kangakanani.

imishini

Ngaphezu idrayivu, sidinga:

- capacitors ezimbili: polar 2200 UF futhi 100 PF;

- 3.6V ugesi, 150-170 ma (inombolo efanelekayo ibhethri okucishe kufane nalokhu izingcingo);

- Resistor 2 ... 5 ohms;

- izindlu nge ukushisa echibini (ne laser kuyinto ngempela ukufuthelana);

- yensimbi nokunamathisela ngomthofu;

- ukufakwa kokumqoka kuphela, impintshisi, kagetsi.

isizinda

Ake ukushayela. Kube sizobonisa ezimbili laser IR-laser ukuthi lifunde ulwazi (kuzokwenza lens) kanye ukuqopha optical, kuba yilokho kanye esikufunayo. Ngaphezu laser, ungakhohlwa ukuze uthole okuthe xaxa kanye lens. Lokhu kumele kwenziwe ngokucophelela ukuze kungabi bikho ukulimala izingxenye ezidingekayo. Isexwayiso! Lapho usebenza nge laser gwema noma yimiphi static, kwakungase ukuphazamisa isimo sawo futhi ibe diode abavamile. Ngaphezu kwalokho, kuwo + nangayiphi indlela uxhumeke ibhethri ngqo.

uhlelo

Ngomsebenzi wokugqokwa laser Uzodinga wesifunda electronic ukuthi kungaba yisiphi solder. Siqukethe capacitors ezimbili ezixhunywe isiqeshana parallel komunye nomunye bese kuya laser ngokwayo (omuhle polarity okukhipha capacitor is soldered okokufaka we-laser kanye omuhle isigxobo SP). Ngaphezu kwalokho, ukuba okukhiphayo omuhle SP soldered Resistor. Schema kungafakwa. Kulesi uhlelo ukulahlekelwa okusezingeni eliphezulu isici, kodwa kuqondile. Uma ufuna ukwenza okuthile okwengeziwe ngokuzumayo, kungenzeka ukuba solder isikimu eziyinkimbinkimbi esekelwe LM317 noma chip LM2621.

ukulungiswa

Nokho, uma nje uvule laser, ngeke ukhiqize ugongolo. It bayokhanya njengokukhanya flashlight, obomvu kuphela. Indlela yokwenza laser ngezandla yakho kusukela kule divayisi? Masikhumbule ukuthi kwenye akhishwa idrayivu lens. Ingasetshenziselwa ukugxila ukukhanya ku ububanzi ugongolo 1 mm noma iphuzu buqamama. Uma udinga pointer, kungcono uvumelane ugongolo, nishise iphuzu elula kakhudlwana. Yonke idivayisi ibekwe endaweni izindlu unikezwe inkinobho nokushaya komoya. Idivayisi usulungile.

ukuphepha

Isexwayiso! I laser unamandla kakhulu! into enjalo uzovutha retina kalula yinoma ngubani abheke ngaphakathi kuwo. Kunoma ikuphi, ngaphambi laser DVD, obzavedites amagogolo. Futhi ungalokothi ukhombe ngqo ebusweni bomuntu!

Manje njengoba siyazi ukuthi ukwenza laser ngezandla zakho, ungaqala ukuthungela yemidlalo, ukuzisika amaphakheji nezinye izenzakalo ezithakazelisayo.
