Ko te pūtake o te whakarerekētanga ā-wāhanga:
Ko te tohu auau reo irirangi he mea hanga mai i te kaikawe hurihuri i te āhua o te ngaru sine, koinei te pūtake o te tohu. Ka whai te kaha tere i tēnei pihi i roto i te ahunga pai, kātahi ka kino, ka hoki ki te pūwāhi tīmatanga i muri i te huringa katoa - ka whai i te pihi o te ngaru sine. Ka taea hoki te whakaatu i te ngaru sine mā te nekehanga huri noa i tētahi pūwāhi i roto i te porowhita, ā, ko te āhua i tētahi pūwāhi ko te Koki i waenganui i te pūwāhi tīmatanga me te pūwāhi i runga i te āhua ngaru. Ka neke haere anō te āhua i roto i te wā, nō reira ka taea te kī he rerekētanga āhua kei waenganui i a rātou ngā pūwāhi i runga i te āhua ngaru. Ka mahi te whakarerekētanga āhua mā te whakarerekē i te āhua o te tohu, arā, te whakarerekē i te tere o te neke o te pūwāhi huri noa i te porowhita. Ki te kore e whakamahia te whakarerekētanga, ka whakarerekē tēnei i te āhua o te tohu. Arā, ka whakarerekētia te tere hurihuri huri noa i te porowhita e pā ana ki te toharite. Mō tēnei, me whakarerekē te auau o te tohu i roto i te wā poto. Arā, ina whakamahia te whakarerekētanga āhua ki te tohu, ka puta he huringa auau, ā, ko te ritenga kē. He hononga kore e taea te wehewehe i te āhua me te auau nā te mea he wāhanga whakauru te āhua o te auau.
TE WHAKATAUNGA: Hei whakanui ake i te wehenga tāuru-putanga o te pūwhakarerekētanga ā-wāhanga katoa mā te whakarato i tētahi ara iahiko tautuhinga kore e hanga ana i te ngaohiko tohu mai i tētahi ara iahiko taraiwa kia kore ina whakamahia he tohu tapahi kawe. TE TŪRANGA: Ko te ara iahiko pana diode 10 he ara iahiko pana momo tātari-iti e rima-wāhanga e whakamahi ana i ngā diode PIN 12 me te 14; ina whakamahia ngā ngaohiko rerekē te ahunga ki ngā diode 12 me te 14 mai i te ara iahiko whakahaere 16, ka tahuri te pana, ā, ina whakamahia ngā ngaohiko whakamua, ka rere ngā diode 12 me te 14 ki te hanga i tētahi ara iahiko poto, ā, ka tapahia he kawe. Ka whakamahia e te ara iahiko whakahaere 16 ngā ngaohiko whakamua ki ngā diode 12 me te 14 e whakamahia ana me te tohu tapahi kawe. Ko te ara iahiko taraiwa 30, ina whakamahia te tohu tapahi kawe mā te raina 40, ka whakahaere kaha i tētahi tohu ngaohiko kia tukuna mai i te pūwhakarerekētanga PSK ā-wāhanga rua 20 ki te kore.
