"Indoda yeqhwa u-Otzi" odumileyo weXesha leLitye, ofunyenwe kwiqhwa lentaba, wayenetattoos.
Kudala, ubugcisa bokugqobhoza nokudaya ulusu lomntu busasazeke kwiinkcubeko ezahlukeneyo. Luphantse lube ngumkhwa wehlabathi, ngenxa yenxalenye yoomatshini bokudweba imifanekiso ngombane. Banokufaka ulusu ngokukhawuleza kakhulu kuneenaliti zemveli ezisetyenziswa phakathi kweminwe yomzobi wokudweba imifanekiso. Kwiimeko ezininzi, i-hollow cup brushless motor iqinisekisa ukusebenza ngokuthula komatshini ngesantya esilawulwayo kunye nokungcangcazela okuncinci.
Oko sikubiza ngokuba yi "tattoo" kuvela kulwimi lwasePolynesia. NgesiSamoa, uTatau uthetha "ngokuchanekileyo" okanye "ngendlela echanekileyo." Luphawu lobugcisa obuthambileyo, obungokwesiko bokudweba iitattoo kwinkcubeko yasekuhlaleni. Ngexesha lobukoloniyali, abaqhubi beenqanawa babuya neetattoo kunye nembonakalo evela ePolynesia baza bazisa imfashini entsha: ukuhombisa ulusu.
Kule mihla, kukho ii-studio ezininzi ze-tattoo kuzo zonke izixeko ezinkulu.
Ukususela kwiimpawu ezincinci zeYin neYang ezisemaqatheni ukuya kwimifanekiso emikhulu yamalungu ahlukeneyo omzimba iyafumaneka. Yonke imilo kunye noyilo onokulucinga lunokufezekiswa, kwaye imifanekiso eluswini idla ngokuba yobugcisa obukhulu.
Isiseko sobugcisa asikokuphelela nje kwizakhono ezisisiseko zomzobi wetattoo, kodwa sikwaxhomekeke kwizixhobo ezifanelekileyo. Umatshini wetattoo usebenza njengomatshini wokuthunga: inaliti enye okanye ezingaphezulu zigqojozwa eluswini ngokuzijika. Ipigment ifakwe kwiindawo ezifanelekileyo zomzimba ngesantya samawaka aliqela eentsiba ngomzuzu.
Kwiimashini zetattoo zanamhlanje, inaliti iqhutywa yimoto yombane. Umgangatho wokuqhuba ubalulekile kwaye kufuneka ungabi nantshukumo kwaye usebenze ngokuzolileyo kangangoko kunokwenzeka. Ekubeni itattoo inokuhlala iiyure ngexesha, umatshini kufuneka ube lula kakhulu, kodwa unike amandla afunekayo -- kwaye wenze iitattoo ezininzi ixesha elide. Abaqhubi beDC abasebenzisa isinyithi esixabisekileyo kunye nabaqhubi beDC abangenamabhulashi abanee-driver zokulawula isantya ezakhelwe ngaphakathi bafanelekile ukuhlangabezana nezi mfuno. Banobunzima obuyi-20 ukuya kwi-60 grams kuphela, kuxhomekeke kwimodeli, kwaye basebenza kakuhle ngama-92 ekhulwini.
Iingcali zobugcisa bokwenza iitattoo zizibona zingabaculi, kwaye izixhobo ezisezandleni zabo sisixhobo sokubonisa ubugcisa bazo.
Iitattoo ezinkulu zihlala zifuna iiyure zomsebenzi oqhubekayo. Ngenxa yoko, umatshini wetattoo wanamhlanje awudingi nje ukukhanya, kwaye kufuneka uguquke kakhulu, unokuhamba uye nakweyiphi na indlela. Ukongeza, umatshini wetattoo olungileyo kufuneka ube nokungcangcazela okuncinci kunye nokubamba ngokukhululekileyo.
Xa ujonga kuqala, umatshini wetattoo usebenza njengomatshini wokuthunga: inaliti enye okanye ezingaphezulu ziyajikeleza eluswini. Amawaka eembobo ngomzuzu angenza umbala ube kwindawo ekufuneka ube kuyo. Umzobi wetattoo onobuchule akayi kungena nzulu kakhulu okanye angabi nzulu kakhulu, kwaye umphumo ofanelekileyo kukuba ube phakathi kolusu. Kuba ukuba ilula kakhulu, itattoo ayizukuhlala ixesha elide, kwaye ukuba inzulu kakhulu, iya kubangela ukopha kwaye ichaphazele umbala.
Oomatshini abasetyenziswayo kufuneka bahlangabezane neemfuno zobugcisa nezoyilo eziphezulu kwaye basebenze ngokuchanekileyo nangokuthembekileyo. Ekubeni olu tyando lwenziwa kwiindawo zomzimba ezibuthathaka, njengamehlo, isixhobo kufuneka sithule kakhulu xa sisebenza. Ngenxa yokuba imilo yesixhobo inde kwaye incinci, kungcono ukuba ibe bukhulu bepeni yebhola, ngoko ke ifaneleke kakhulu kwii-micromotor ze-DC ezincinci kakhulu.
Njengoko sineempawu zobugcisa ezibalaseleyo, injini yethu inomlinganiselo ophezulu wokusebenza kakuhle, nto leyo eluncedo kakhulu kwimo yebhetri.
Ubuninzi bamandla aphezulu bubangela izisombululo zokuqhuba ezixineneyo nezikhaphukhaphu, ezifana nobubanzi obuyi-16mm kwizixhobo zokuthambisa ezihlala ziphathwa ngesandla.
Xa kuthelekiswa nemoto ye-DC eqhelekileyo, izixhobo zethu zahlukile kwi-rotor. Ayijikeleziswanga kwisiseko sentsimbi, kodwa yenziwe yi-coil yobhedu ejikelezayo ezixhasayo. Ke ngoko, ubunzima be-rotor bulula kakhulu, ayisebenzi nje kuphela ngokuthula, kodwa ikwanazo neempawu eziphezulu ze-dynamic, akukho siphumo se-alveolar, okanye isiphumo se-hysteresis esiqhelekileyo kwezinye iiteknoloji.
