Riaan Le Raspberry Pi ingakala amasiginali we-EEG.
Kwesinye isibonelo esihle kakhulu somphakathi we-Raspberry Pi ukwenza izinto ezimangalisayoumcwaningi waseNyuvesi yase-Heriot-Watt usungule idivayisi ethengekayo yokulinganisa nokuqopha izimpawu ze-EEG ezikhiqizwa ubuchopho.
Ngokusho kokuthunyelwe okusha kwebhulogi ku- Iwebhusayithi yeRaspberry PiIsazi sezinzwa okuthiwa u-Ildar Rakhmatulin wasebenzisa inkundla ye-Raspberry Pi futhi wadala uhlelo lokukala i-EEG (i-electroencephalogram), i-ECG (i-electrocardiogram), kanye nama-EMG avela emzimbeni womuntu.
Le gajethi encane ingakwazi ukukala amasignali obuchopho, empeleni okuwuhlobo lwesixhumi esibonakalayo sekhompiyutha yobuchopho. Akugcini lapho, futhi. Ingakwazi ukufunda nokukala ama-microvolts.
Imvamisa, ososayensi be-Neuroscientists basebenzisa ama-amplifiers ayinkimbinkimbi futhi abizayo ukuze enze umsebenzi onjalo, kodwa u-Rakhmatulin uthemba ukuthi ukwakhiwa kwakhe kwe-Raspberry Pi ngokwezifiso kungaholela ekuhloleni okuthengekayo nokuphumelelayo. Ekugcineni, umdali uthemba ukuthi kuzoba yisixazululo sokugcina, asibizayo I-PiEEG.
Ngakho konke lokhu kusebenza kanjani? U-Ildar usebenzisa ama-electrode ukuze athinte isikhumba noma izicubu zomuntu, ezibe sezixhunywa ebhodini lakhe le-PiEEG langokwezifiso elisebenzisa isofthiwe azibhalele yona. Isistimu ithwebula amasiginali kagesi ebuchosheni, iwafake kudijithali, bese ikhipha okurekhodiwe okufundekayo ku-Pi. Kukhona nezihlungi ezikhona zokubamba nokuhlanza noma yikuphi ukuphazamiseka.
Cabanga uthwebula futhi ucubungule amasignali obuchopho ngesikhathi sangempela, bese ukhiphela lezo zimpawu ezingalweni zerobhothi noma ezithweni ezishintshayo. Lezi yizinto ezimbalwa nje ezingase zisetshenziswe kudivayisi enjalo. Angiyena i-Neuroscientist, kodwa lokhu kuzwakala kumangalisa kakhulu. Imininingwane eyengeziwe mayelana nephrojekthi ithi iyatholakala ku-GitHub.
