Hei Habr. Muchinyorwa chino, ini ndichataura nezve yangu yazvino kusikwa, yakagadzirwa kubva ku500 laser modules, seyakachipa yakaderera-simba laser pointers. Kune akawanda mapikicha anodzvanya pasi pekuchekwa.

Attention! Kunyangwe yakaderera-simba laser emitters mune mamwe mamiriro anogona kukonzera kukuvadza kuhutano kana kukuvadza mafoto emidziyo. Usaedza kudzokorora kuedza kunotsanangurwa munyaya yacho.

Cherechedza. On YouTube ine vhidhiyo yangukwaunogona kuona zvakawanda. Nekudaro, chinyorwa chinotsanangura maitiro ekugadzira zvakadzama uye pano mufananidzo uri nani (kunyanya kana wadzvanywa).

Laser modules

Ini ndichatanga netsanangudzo yelaser modules ivo pachavo. Kune akawanda akasiyana sarudzo dzekutengesa ikozvino, dzakasiyana muwavelength, simba uye chimiro chekubuda kwemwaranzi, dhizaini ye optical system uye kukwira, pamwe nekuvaka mhando uye mutengo.

Ndakasarudza mamodule akachipa anotengeswa kuChina mumabhechi ezvimedu zana anokosha anenge 100 rubles pabatch. Zvinoenderana nerondedzero yemutengesi, vanopa 1000 mW paavelength ye50 nm. Kana ari 650 mW, ini ndinokahadzika, kazhinji hapana kana 50 mW. Ndakatenga akawanda mamodule akafanana muRussia pamutengo we5 rubles imwe neimwe. Muzvitoro zvepamhepo, anowanikwa pasi pezita LM30R-dot-6V. Ivo vanopenya senge tsvuku laser anonongedzera, anotengeswa akasiyana siyana mune chero chitoro chine knick-knacks.

Zvimiro, iyi module inotaridzika sesimbi silinda ine dhayamita 6 mm uye kureba 14 mm (pamwe chete nebhodhi). Iyo midziyo yemuviri ingangoita simbi, sezvo ine yakanaka magineti maitiro. Imba yacho yakabatana neiyo yakanaka kuonana.

Mukati mekesi mune lenzi yepurasitiki uye laser chip yakaiswa padiki rakadhindwa redunhu board. Iko kunewo resistor pabhodhi, kukosha kwayo kunoenderana neyakaziviswa yekugovera voltage. Ndakashandisa 5V modules ine 91 ohm resistor. Iine voltage yekupinda ye5V pane module, iyo voltage pane laser chip ndeye 2.4V, nepo ikozvino iri 28 mA. Iyo yakagadzirwa yakazaruka zvachose kubva parutivi rwebhodhi, kuitira kuti chero guruva kana unyoro hunogona kupinda mukati. Naizvozvo, ndakaisa chisimbiso kuseri kwemodhi yega yega neglue inopisa. Uye zvakare, iyo chip uye lens hazvina kumira zvakanaka, saka iyo inobuda inogona kunge isingaenderane neakisi yeimba. Panguva yekushanda, module inopisa kusvika kune tembiricha ye35-40 ° C.

original version

Pakutanga (rakanga riri gore rapfuura) ndakatenga mazana maviri laser modules uye ndakasarudza kuvatungamirira kune imwe pfungwa ndichishandisa nzira yejometri chete, kureva, pasina kugadzirisa imwe neimwe module, asi nekuisa imwe neimwe emitter mune yakakosha cutouts. Kuti ndiite izvi, ndakarayira zvigadziro zvakakosha zvakagadzirwa neplywood 200 mm gobvu.

Iwo laser modules akatsikirirwa pachekuchekwa uye akanamatira ne glue inopisa. Mhedzisiro yacho yaive setup yakaburitsa danda re200 laser dots ine dhayamita ingangoita 100 mm. Kunyange zvazvo chigumisiro chacho chakanga chiri kure nekurova imwe pfungwa, vazhinji vakafadzwa nemafungiro aya (ndakatumira vhidhiyo pa youtube) uye zvakasarudzwa kuenderera mberi nehurukuro.

Ndakabvisa system ye200 laser modules ndikagadzira laser garland kubva mairi. Zvakava zvinonakidza, asi hazvina kunaka, sezvo pasi pehuremu hwemuviri marara ose aitungamirirwa pasi. Asi panguva ino ndakatenga muchina wefodya uye kekutanga ndakaona kutonhorera kwema lasers mumhute. Ndakafunga kudzokorora zano rekutanga, asi nemaoko tungamira laser yega yega kune imwe pfungwa.

laser chiedza

Kune iyo vhezheni itsva, ndakaraira mamwe mazana matatu laser module. Sechitsigiro, ndakagadzira ndiro ine rutivi rwe 300 mm kubva paplywood 440 mm gobvu ine matrix emakomba emitsara makumi maviri neshanu uye 6 columns. Gomba dhayamita 25 mm. Gare gare ndakaipenda yesirivha. Kuti ndiise ndiro, ndakashandisa chigadziko kubva kune yekare LCD monitor.

Ndakagadzirisa ndiro muvhavha, uye kureba kwe1350 mm (kureba kwetafura yangu) ndakarembera chinangwa chepepa chinoyera 30x30 mm, pakati pacho ndakatungamirira danda rimwe nerimwe re laser.
Maitiro ekunamira iyo laser module yaive yakadai. Ndakapinza tambo dzemodule mugomba ndokubatanidza ngwena nemagetsi ekupa. Tevere, ndakazadza module kesi uye gomba mundiro neinopisa glue. Pasi pendiro isa feni yekumhanyisa kutonhora kweglue. Sezvo glue richiomesa zvishoma nezvishoma, ndaigona kugadzirisa zviri nyore chinzvimbo chemodule, ndichitarisa pane chinzvimbo che laser dot pane chinangwa. Paavhareji, zvakanditorera 3.5 maminetsi kune imwe laser module.

Zviri nyore kushandisa inopisa melt glue, sezvo inogona kudziyisa uye module yakagadziriswa. Zvisinei, pane zvipingamupinyi zviviri. Kutanga, kupisa kwemamodules kwakatungamira ku deformation yemodule chimiro, iyo yakaratidzwa mukuwedzera kweiyo laser beam. Mamwe ma module akarasikirwa nekupenya kwawo zvakanyanya kubva pakudziya uye aifanira kutsiviwa. Kechipiri, mushure mekutonhodza, iyo inopisa inonyunguduka yakanamatira yakaramba ichikanganisa kwemaawa akati wandei uye nekutsausa zvishoma danda relaser munzira yekupokana. Chinhu chekupedzisira chakamanikidzwa kushandura zita rekutanga repurojekiti "500 laser pointers pane imwe nguva."

Sezvo basa racho raiitwa pano neapo manheru uye pakupera kwevhiki, zvakatora inenge mwedzi mitatu kunama ese mazana mashanu laser modules. Tichifunga nezvekuendeswa kwemamodule uye ndiro, pachava nemwedzi mitanhatu.

Nekuita kwakakosha, ini ndakawedzera ma LED ebhuruu kune laser modules.

Kupa simba kune ese mamodule harisi basa riri nyore, nekuti iwe unofanirwa kubatanidza 1000 kutaurirana uye kugovera zvakaenzana ikozvino. Ndakabatanidza 500 positive contacts mudunhu rimwe chete. Ndakapatsanura ma negative contacts mumapoka gumi. Boka rega rega rine switch yaro yekuchinja. Mune ramangwana, ndichawedzera 10 microcontroller-inodzorwa makiyi emagetsi kumimhanzi kuti mapoka agonese.

Kuti ndiise simba mamodule ese, ndakatenga anogara ari voltage sosi Zvinoreva Zvakanaka LRS-350-5, iyo inogadzira voltage ye5V ine ikozvino inosvika ku60A. Iyo ine saizi diki uye yakanakira terminal block yekubatanidza mutoro.

Dunhu rekupedzisira rine ese laser modules akabatidzwa ane kushandiswa kweanosvika gumi nemana amperes. Mufananidzo uri pazasi unoratidza nzvimbo yeese laser dots pane chinangwa. Sezvauri kuona, ini ndoda kukwana mu "nzvimbo imwe" ine saizi ye14x30 mm. Imwe nzvimbo kunze kwechinangwa yakaonekwa nekuda kweimwe module ine spurious side radiation.

Chigadzirwa chinoguma hachitaridzike chakanyanya kunaka, asi kunaka kwayo kwese kunoratidzwa murima nemhute.

Ndakaedza kubata mharadzano yemaranzi. Kudziya kunonzwa, asi kwete kusimba.

Uye akatonongedza kamera zvakananga kune emitters (ini pachangu ndinoshandisa magirazi egirini).

Zvainakidza chaizvo kushandisa magirazi nemalenzi.

Gare gare, ini ndakawedzera kugona kugadzirisa laser modules neinonzwika chiratidzo uye ndakawana mhando yekumisikidzwa kwelaser. Unogona kumutarisa muvhidhiyo yangu yeYouTube.

Iyi purojekiti ndeyekutandara chete uye ndakafadzwa nemhedzisiro yayo. Parizvino, ini handizvimisi mabasa akafanana anotora nguva, asi mune ramangwana ndingangouya nechimwe chinhu. Ndinovimba wakafarirawo.

Спасибо за внимание!
