El I-DuoGraph Ungumshini wokudweba wakamuva ovela kumsunguli nomklami uJoe Freedman, 'i-Cycloid Drawing Machine' yakhe edale isiphepho se-inthanethi ezinyangeni ezimbalwa ezedlule. Imishini yayo ebanzi iyakwazi ukukhiqiza amaphethini wejometri afanayo afana ne-a I-Spirograph kuma-steroids. Lokhu kudalwa okusha kulula ukusetha nokusetshenziswa, njengoba iqukethe amagiya ayi-7 nenani lamapharamitha angashintshwa masishane ukukhiqiza ukwakheka okungapheli. Ngenkathi i-DuoGraph ikhawulelwe kakhulu ezingeni layo lokwenza ngokwezifiso, iyakwazi ukukhiqiza izibalo ezicacile ze- 'Lissajous'kanti amadivayisi amakhulu awakwazi. Ngemuva kwalokho sikushiya a ividiyo komshini.
Lo ngumshini wami wesine nowokugcina ozodweba. Mina 'Umshini Wokudweba I-cycloid' bekungumshini wokudweba omuhle kakhulu engikwazi ukuwenza. Bengicabanga ukuthi kuzoba ngumshini wokugcina wokudweba, kepha abanye abantu babuze ukuthi uwuthola kanjani omunye wemishini yami yokuqala. Ngimbize nge I-PrimoGraf, hhayi ngoba bekungenxa yokuthi bekungeyokuqala kepha kunalokho ngoba ngidwebe amajika lissajous ngokuya ngesilinganiso sezinombolo eziyinhloko. Bekuyithoyizi elincane elihle elingena ebhokisini lokhuni futhi linamagiya ayi-7 kuphela. Kwakulinganiselwe, kodwa kumnandi. IPrimoGraf bekuwumsebenzi omuhle futhi abantu abaningi bathanda ukudlala ngomshini.
I-DuoGraph entsha igcwalisa iphupho lami lomshini omncane oyinkimbinkimbi we-epicycloid ongekho mkhulu kakhulu. Inikeza nethuba lokwenza amajika eLissajous futhi. I-DuoGraph iyaqhubeka namandla e-fulcum yeselula ye-cycloid. Okuwukuphela kwezici ze-cycloid ezingenazo ukusethwa kwamagiya aseplanethi. Akunandawo yabo kumagiya amancane.
Ulwazi oluningi ngakho ku I-Kickstarter.
