I-Ovrdrive sisixhobo se-USB esithi, ekuqalekeni, sijonge njengependrive eqhelekileyo. Nangona kunjalo, inomsebenzi okhethekileyo wokhuseleko: isebenza kuphela kwaye ibonise umxholo wayo xa udibanisa kathathu ngokulandelelana ngokukhawuleza. Esi sixhobo sijolise kwiintatheli kwiindawo ezicinezelayo kunye nabaphandi bokhuseleko, kodwa sinokuba luncedo kwezinye ii-hardware zomthombo ovulekileyo kunye nabathandi babucala.
Ukusebenza kwe-Ovdrive kusekelwe kwiisekethe ezimbini ezifanayo eziqhagamshelwe kwi-a Umlawuli omncinci we-ATtiny24A elawula ukusebenza koqhagamshelwano olukhawulezayo. Xa umbane uqhagamshelwe, i-microcontroller inika amandla phezulu kwaye i-CHG1 node ihlawulisa nge-D2, ihlale iphakamileyo ixeshana ngaphambi kokuba ikhuphe kancinci nge-R1 kunye nokumelana nomzimba. I-Capacitors C3 kunye ne-C14 zihlala zihlawuliswa ngexesha lomjikelo wokuvula / wokuvala ngokukhawuleza.
Nangona imbonakalo yayo eqhelekileyo, I-Ovdrive ibonelela ngokhuseleko ebumnyameni, nangona ingenzelwanga ukuthatha indawo yoguqulelo oluntsonkothileyo. Ukongeza, inesekhethi enokuthi ibuyisele umva amandla ombane anikezelweyo kwi-flash chip kwaye iyifudumeze ukuya kuthi ga kwi-100 ° C, enokuthi isebenze njengesixhobo sokwenza "iplanti yokuzitshabalalisa yasekhaya".
Isixhobo yenziwe nguRyan Walker we-Interrupt Labs, inkampani ezinikele ekudaleni i-hardware yomthombo ovulekileyo kunye nesoftware. Zonke isoftware ehambelanayo kunye neefayile zehardware zinokufumaneka kwindawo yokugcina yeGitHub. Iprojekthi ngoku ixhaswa ngemali kwi-Crowd Supply kwaye ifikelele ngaphezu kwesiqingatha senjongo yayo yokunyusa malunga ne-3500 yeedola. I-USB drive inokuthengwa nge-$ 69 ngoku kwi-Crowd Supply, kunye nokuthunyelwa kwamahhala ngaphakathi kwe-US kunye ne-$ 12 yemali yokuthumela kwihlabathi lonke. Iiodolo kulindeleke ukuba zithunyelwe nge-5 ka-Agasti 2024.
