Yize sonke sinekhompiyutha noma ilaptop ekhaya, baningi abasenawo umshini wokubhala abangakawulahli ngenxa yokulangazelela. Futhi nakuba abaningi bekholelwa ukuthi umshini wokubhala awusasebenzi futhi awunanjongo, iqiniso liwukuthi sibonga Hardware Libre Kuyidivayisi esetshenziswa ngokuya ngokuya.
Umsebenzisi ongumenzi, UKonstantin Schauwecker ukwazile ukuguqula umshini wokubhala omdala ube yikhibhodi engenantambo esebenza futhi ixhuma kwikhompyutha. Inqubo yenguquko ilula kodwa yinde futhi idinga imali encane.
UKonstantin Schauwecker usebenzise umshini wokubhala omdala wase-Olympia ukudala le khibhodi. Into yokuqala eyenzile ukugcwalisa ukhiye ngamunye ngama-phototransistors anomthwalo wokuthumela i-keystroke. Ngemuva kwalokho uxhume wonke lawa ma-phototransistors ku- i-PCB ayidalile uqobo. Uma usuxhume konke, Ibhodi le-PCB lixhunywe ku-Arduino Leonardo, ukuze umshini wokubhala ukwazi ukuxhunywa kukhompyutha noma kwi-laptop. Lapho umshini usuxhumekile ebhodini le-Arduino, kufanele sixhume i-Arduino Leonardo kuphela ku-pc. Lokhu kuzosinika ikhibhodi yendabuko, okungukuthi, ikhibhodi enentambo. Kepha singashintsha ibhodi lika-Arduino Leonardo no-Arduino Yún, kulokhu sizoba nekhibhodi engenantambo.
Inqubo ilula, kepha umsebenzi mude ngoba kufanele xhuma i-phototransistor ngayinye kukhiye ngamunye wokubhala bese uya ebhodini le-PCB. Kepha ngemuva kwalo msebenzi sizoba namagajethi amabili koyedwa: umshini wokubhala wakudala nekhibhodi engenantambo.
Ungathola umhlahlandlela wokwakha kanye nezinhlelo ze-pcb lapha. Ngamanye amagama, noma ngubani angazakhela eyakhe ikhibhodi yokubhala ngomshini omncane. Yize uma sifuna ukonga isikhathi, singahlala sikhetha ikhibhodi yendabuko yekhompyutha.
