"Iceman Otzi" wotchuka wa m'nthawi ya miyala, yemwe anapezeka pa phiri la chisanu, anali ndi zizindikiro.
Kalekale, luso loboola ndi kupaka utoto khungu la anthu lakhala likufalikira m'zikhalidwe zosiyanasiyana. Ndi chizolowezi chapadziko lonse lapansi, chifukwa cha makina amagetsi ojambulira zojambulajambula. Amatha kuyika khungu mwachangu kwambiri kuposa singano zachikhalidwe zomwe zimagwiritsidwa ntchito pakati pa zala za wojambula zojambulajambula. Nthawi zambiri, mota yopanda chipewa chopanda burashi imatsimikizira kuti makinawo akuyenda bwino komanso mwachangu komanso kugwedezeka kochepa.
Chimene timachitcha kuti "tattoo" chimachokera ku chilankhulo cha ku Polynesia. Mu Chisamoa, tatau amatanthauza "molondola" kapena "m'njira yoyenera." Ndi chithunzi cha luso losavuta komanso lamwambo lojambula tattoo m'chikhalidwe cha anthu am'deralo. Mu nthawi ya atsamunda, anthu oyenda panyanja adabweretsa tattoo ndi mawonekedwe ochokera ku Polynesia ndipo adayambitsa mafashoni atsopano: kukongoletsa khungu.
Masiku ano, pali malo ambiri ojambulira tattoo mumzinda uliwonse waukulu.
Kuyambira zizindikiro zazing'ono za Yin ndi Yang pa akakolo mpaka zojambula zazikulu za ziwalo zosiyanasiyana za thupi zilipo. Mawonekedwe ndi kapangidwe kalikonse komwe mungaganizire kangathe kuchitika, ndipo zithunzi zomwe zili pakhungu nthawi zambiri zimakhala zaluso kwambiri.
Maziko aukadaulo si luso lokha la wojambula zojambulajambula, komanso zimadalira zida zoyenera. Makina ojambulira zojambulajambula amagwira ntchito ngati makina osokera: singano imodzi kapena zingapo zimabowoledwa pakhungu pozigwedeza. Utoto umalowetsedwa m'malo oyenera a thupi pamlingo wa minga zikwi zingapo pamphindi.
Mu makina amakono ojambulira tattoo, singano imayendetsedwa ndi mota yamagetsi. Ubwino wa choyendetsa ndi wofunika kwambiri ndipo uyenera kukhala wopanda kugwedezeka ndipo uyenera kuyenda mwakachetechete momwe ungathere. Popeza tattoo imatha kukhala kwa maola ambiri, makinawo ayenera kukhala opepuka kwambiri, koma amapereka mphamvu yofunikira -- ndikuchita tattoo zingapo kwa nthawi yayitali. Madalaivala a DC opangidwa ndi zitsulo zamtengo wapatali komanso madalaivala a DC opanda burashi okhala ndi madalaivala owongolera liwiro lomangidwa mkati ndi abwino kwambiri pokwaniritsa zofunikira izi. Amalemera magalamu 20 mpaka 60 okha, kutengera mtundu, ndipo amagwira ntchito bwino ndi 92 peresenti.
Akatswiri ojambula zithunzi amadziona ngati akatswiri ojambula, ndipo zida zomwe ali nazo m'manja mwawo ndi chida chowonetsera luso lawo.
Ma tattoo akuluakulu nthawi zambiri amafuna maola ambiri ogwira ntchito mosalekeza. Chifukwa chake makina amakono olembera ma tattoo samangofunika kuwala kokha, komanso ayenera kukhala osinthasintha kwambiri, amatha kuyenda mbali iliyonse. Kuphatikiza apo, makina abwino olembera ma tattoo ayeneranso kukhala ndi kugwedezeka pang'ono komanso kugwira bwino ntchito.
Poyamba, makina olembera tattoo amagwira ntchito ngati makina osokera: singano imodzi kapena zingapo zimadutsa pakhungu. Mabowo ambirimbiri pamphindi imodzi amatha kupangitsa utoto kukhala pamalo oyenera. Wojambula tattoo waluso sadzafika mozama kwambiri kapena mozama kwambiri, ndipo zotsatira zake zabwino kwambiri ndi khungu lapakati. Chifukwa ngati ndi lopepuka kwambiri, tattoo siidzakhala nthawi yayitali, ndipo ngati ndi yozama kwambiri, imayambitsa kutuluka magazi ndikukhudza mtundu.
Makina omwe amagwiritsidwa ntchito ayenera kukwaniritsa zofunikira kwambiri paukadaulo ndi kapangidwe kake ndipo ayenera kugwira ntchito molondola komanso modalirika. Popeza ntchitoyi imachitika mozungulira ziwalo zofewa za thupi, monga maso, chipangizocho chiyenera kukhala chete kwambiri chikagwiritsidwa ntchito. Popeza mawonekedwe a chipangizocho ndi aatali komanso opapatiza, ndibwino kuti chikhale chofanana ndi cholembera cha ballpoint, kotero ndi choyenera kwambiri pa ma micromotor a DC owonda kwambiri.
Ndi makhalidwe abwino kwambiri aukadaulo, mota yathu ili ndi mphamvu zambiri, zomwe zimathandiza kwambiri pa batri.
Mphamvu zambiri zimapangitsa kuti pakhale njira zoyendetsera zopapatiza komanso zopepuka, monga mainchesi 16mm a zida zodzoladzola zokhazikika zomwe zimagwiritsidwa ntchito m'manja.
Poyerekeza ndi mota ya DC, zida zathu ndi zosiyana mu rotor. Sizimazungulira pakati pa chitsulo, koma zimapangidwa ndi coil yamkuwa yozungulira yokha. Chifukwa chake, kulemera kwa rotor ndi kopepuka kwambiri, sikuti imagwira ntchito chete, komanso ili ndi mawonekedwe amphamvu kwambiri, osati mphamvu ya alveolar, kapena mphamvu ya hysteresis yomwe imapezeka m'maukadaulo ena.
